Quick Overview:
- Total Everest death toll (to end of 2025): At least 344 confirmed fatalities
- Current mortality rate above base camp: Approximately 0.7% (2007 to 2024)
- Everest yearly deaths average: 5 to 8 per year in the modern era (2010 to 2025)
- Deadliest recent season: 2023 with 17 to 18 deaths recorded
- 2025 season deaths: 5 fatalities, one of the lowest tolls in recent years
Few mountains in the world carry the weight of myth, ambition, and tragedy quite like Mount Everest. At 8,848.86 metres above sea level, the world’s highest peak has drawn tens of thousands of climbers since the first recorded attempts in the 1920s. And with every expedition comes an uncomfortable question that never loses its urgency: what is the Everest mortality rate, and just how dangerous is this mountain in 2026?
The numbers tell a story that is both sobering and, in some ways, surprisingly hopeful. A landmark study published in the Journal of Physiology in 2025 found that the overall Everest mortality rate above base camp declined from 1.4% for the period 1921 to 2006, down to 0.7% for the period 2007 to 2024. That represents a dramatic improvement in safety across more than a century of climbing. Yet the total Everest death toll continues to grow with every season, and the mountain remains, without question, one of the most dangerous places on earth.
Whether you are researching for an upcoming expedition, following the stories of those who died on Everest, or simply trying to understand the true risks of the world’s tallest mountain, this complete guide gives you the full picture: the statistics, the causes, the deadliest seasons, and the honest reality of climbing Everest in 2026.
What Is the Everest Mortality Rate and How Is It Measured?
The Everest mortality rate is not a single fixed number. It depends heavily on how and where you measure it, which era of climbing you examine, and whether you count all attempts above base camp or only summit bids on the standard routes.
The most widely referenced figure comes from the Himalayan Database, the most comprehensive record of Himalayan expeditions ever compiled. Based on this data, the overall mortality rate for climbers above Everest Base Camp across all of recorded climbing history stands at approximately 1.06 deaths per 100 summits. In practical terms: roughly 1% of everyone who ventures above base camp on Everest has died on the mountain.
However, that headline figure masks important nuance. The rate has shifted significantly across different eras of climbing:
- 1921 to 2006: Mortality rate above base camp was approximately 1.4%
- 2007 to 2024: The rate fell to approximately 0.7%, representing a halving of risk
This improvement coincides with the rise of commercial expeditions, advances in weather forecasting, wider use of supplemental oxygen, improved fixed-rope systems, and better logistical support. According to the peer-reviewed research published in the Journal of Physiology in 2025, more than three-quarters of all recorded Everest summit ascents occurred after 2007, yet the death rate fell substantially in that same period.
What has not changed is where people die. The most dangerous phase of any Everest climb remains summit day itself. More than 76% of climber deaths from 1921 onwards occurred during the descent from extreme altitude. Climbers who reach the top are operating at peak exhaustion in the death zone above 8,000 metres, where oxygen levels drop to roughly one-third of what is available at sea level. The descent, not the ascent, is where most lives are lost.
How Does the Everest Death Rate Compare to Other 8,000-Metre Peaks?
Context matters when evaluating the Everest mortality rate. Compared to other peaks in the 8,000-metre category, Everest is actually not the most lethal mountain by percentage. Annapurna I, which rises to 8,091 metres in Nepal’s Gandaki Province, historically carried a fatality rate of around 32% of all attempts in its early climbing era, though improved techniques have reduced this figure significantly in recent decades.
K2 in Pakistan, the world’s second-highest peak, has a mortality rate approximately three times higher than Everest’s modern figure. The difference comes from Everest’s well-established commercial routes, the extensive use of fixed ropes on the standard South Col and Northeast Ridge approaches, and the large network of experienced Sherpa support teams that accompany most expeditions.

How Many People Die on Everest Each Year? A Season-by-Season Breakdown
One of the most searched questions about Everest is: how many people die on Everest each year? The answer varies considerably from season to season, and understanding why requires looking at the data over time.
Based on records from the Himalayan Database and Nepal’s Department of Tourism, here is what the Everest yearly deaths figure has looked like across the modern commercial era:
- 2025: 5 deaths (3 on the mountain, 2 at Base Camp) — one of the lowest recent tallies
- 2024: 8 deaths
- 2023: 17 to 18 deaths — the deadliest season of the modern commercial era
- 2022: 5 deaths
- 2021: 4 deaths (season partially disrupted by COVID-19 protocols)
- 2019: 11 deaths, partly attributed to severe overcrowding near the summit
- 2015: 22 deaths — primarily caused by the devastating Nepal earthquake and resulting avalanche at Base Camp
- 2014: 16 deaths — an ice avalanche in the Khumbu Icefall killed 16 Sherpas in a single incident
- 1996: 15 deaths — immortalised by Jon Krakauer’s Into Thin Air and still one of the most studied disasters in mountaineering history
The long-term average from 2000 to 2019 sits at roughly 3.2 deaths per year, though this figure is pulled downward by relatively quiet years and upward by disaster seasons. In the decade from 2010 to 2024, the annual average has risen to approximately 8, largely due to the outsized 2014, 2015, and 2023 figures.
Why Was 2023 So Deadly?
The 2023 season stands out as a critical case study in what drives the Everest death toll upward. Nepal issued a record 479 climbing permits that year, the highest number ever. Subsequent analysis of the fatalities revealed a disturbing pattern: 23 of the 26 deaths across the combined 2023 and 2024 seasons occurred on lower-cost commercial expeditions. These operators typically provided thinner supplemental oxygen supplies, fewer Sherpa guides per climber, and weaker turnaround discipline.
The data strongly suggests that the overall improvement in the Everest mortality rate has benefited primarily climbers on well-resourced, professionally guided expeditions. Underfunded operations with inadequate support retain fatality rates closer to those of the pre-commercial era.
Nepal responded to the 2023 figures by introducing tighter regulations: mandatory guide-to-climber ratios, enhanced weather systems, and a new permit fee of $15,000 per climber introduced for the 2026 season. Whether these measures will drive a sustained reduction in the Everest death toll remains to be seen.

The Total Everest Death Toll: How Many People Have Died on the Mountain?
The cumulative Everest death toll since climbing records began in 1921 now stands at a minimum of 344 confirmed deaths, according to data from the Himalayan Database and Wikipedia’s list of people who died climbing Everest, which is updated continuously.
This figure includes foreign climbers, Nepali Sherpa guides, and high-altitude support staff. It does not include several deaths that are disputed, unconfirmed, or occurred in incidents where records were incomplete, including alleged deaths on the Chinese-controlled North Face during restricted political periods.
Of the 344 confirmed deaths:
- Approximately 200 to 250 bodies remain on the mountain, unrecovered due to the extreme difficulty and cost of retrieval at high altitude
- Body recovery from above 8,000 metres can cost between $30,000 and $70,000 and requires multiple Sherpa days of dangerous work
- Melting glaciers have begun revealing bodies that were buried for decades, prompting ongoing recovery efforts by the Nepalese government
- Four unidentified bodies were recovered in 2019; another five in 2024
The presence of unrecovered bodies on Everest is a topic that generates enormous interest internationally. Our dedicated guide, How Many Bodies Remain on Mount Everest? The Haunting Reality 2026 Guide, covers this subject in full, including the stories behind several of the mountain’s most recognised landmarks.

What Causes Deaths on Everest? The 6 Leading Killers
Understanding the Everest mortality rate requires understanding what actually kills climbers on the mountain. The causes are multiple, often interrelated, and concentrate in specific zones and phases of the climb.
Altitude Illness: The Silent Killer Above 8,000 Metres
The death zone above 8,000 metres is where oxygen levels drop to approximately one-third of sea-level concentrations. At this altitude, the human body begins to deteriorate regardless of fitness level. Two conditions are particularly deadly:
High Altitude Pulmonary Oedema (HAPE): Fluid builds in the lungs, causing breathlessness, coughing, and ultimately suffocation. Without immediate descent and treatment, HAPE is fatal approximately 50% of the time.
High Altitude Cerebral Oedema (HACE): Fluid accumulates around the brain, causing loss of coordination, confusion, and unconsciousness. HACE can be fatal within 48 hours without intervention.
Many climbers who die on summit day show signs of severe HAPE, HACE, or both, often compounded by exhaustion and dehydration after 15 to 20 hours of continuous high-altitude exertion.
Our comprehensive resource on the Death Zone on Mount Everest: Complete 2026 Survival Guide explains the physiological reality of high-altitude survival in detail every prospective Everest climber should read before committing to an expedition.
Avalanches: Catastrophic and Unpredictable
Avalanches have caused some of the Everest death toll’s single largest spikes. The 2014 Khumbu Icefall avalanche killed 16 Sherpa guides in minutes, making it the single deadliest day in Everest’s history at that point. The 2015 earthquake triggered a massive avalanche that swept through Base Camp and killed 22 people in one afternoon.
The Khumbu Icefall, the chaotic section of broken glacier that climbers must cross immediately above Base Camp, remains one of the most consistently dangerous sections of the standard South Col route. Serac towers the size of houses can collapse without warning.
Falls: The Descent Danger
Falls account for approximately 35% of non-Sherpa deaths on Everest. The risk spikes dramatically during descent when climbers are exhausted, oxygen-depleted, and operating in the dark. The Hillary Step, the Lhotse Face, and the traverse below the South Summit are all technically demanding sections where a single slip can be fatal.
Modern fixed-rope systems have reduced fall-related deaths considerably in the post-2007 era. The peer-reviewed research cited earlier notes that deaths from falls and disappearances above 8,000 metres decreased significantly in the 2007 to 2024 period compared with earlier decades.
Exhaustion and Impaired Decision-Making
The research published in the Journal of Physiology identified profound exhaustion and impaired consciousness as the most frequent symptoms among those who died above 8,000 metres in the modern era, even where falls or obvious altitude illness were absent. The physiological cascade of oxygen deprivation, sleep deprivation across weeks of expedition life, caloric deficit, and dehydration collectively degrade judgement and physical capacity to a degree that sea-level athletes simply cannot simulate.
Many fatal decisions on Everest, including the choice to continue summiting past the 2 PM turnaround rule, to descend without a guide, or to ignore early signs of HACE, happen not because climbers are reckless but because altitude has already compromised the very cognitive functions needed to make safe choices.
Hypothermia and Frostbite
Temperatures on the Everest summit can drop to -60°C (-76°F) in winter, and even during the spring climbing season, summit temperatures range from -20°C to -35°C. Sudden weather deterioration while climbers are exposed in the death zone has historically contributed to a significant portion of fatalities. Notably, the post-2007 research found zero weather-related deaths on the standard routes between 2007 and 2024, a dramatic contrast to earlier decades when approximately 25% of deaths above 7,000 metres were weather-related. This improvement directly reflects advances in meteorological forecasting that now give expedition teams several days of reliable weather windows.

Climbing Without Supplemental Oxygen
The Everest mortality rate for climbers attempting to summit without supplemental oxygen is dramatically higher than for those using it. Traditional estimates place the no-oxygen death rate at upwards of 30%, though this figure fluctuates based on conditions and individual physiology. In 2023, only three climbers attempted a no-oxygen summit, and one disappeared during descent. Without supplemental oxygen, the summit of Everest sits in a zone where no human can survive for extended periods.
Who Is Most at Risk? Climbing Experience and Expedition Quality
Not all Everest climbers face the same level of risk. The data from 2023 and 2024 makes this stark: expedition quality and prior experience are the two strongest predictors of survival.
Experience matters enormously. Climbers who have previously summited peaks in the 6,000 to 7,000-metre range arrive on Everest with practised acclimatisation protocols, genuine knowledge of altitude illness symptoms, and the physical memory of how their bodies respond at high elevation. Those without this background frequently underestimate the speed and severity with which altitude illness develops.
Expedition quality correlates directly with survival. The 2023 and 2024 data showing 23 of 26 deaths on below-median-priced expeditions is not coincidental. Reputable operators maintain strict turnaround rules, adequate Sherpa-to-climber ratios, sufficient oxygen reserves (including emergency supplies), and the authority to halt a client’s summit bid when conditions deteriorate. Cheaper operators frequently cut each of these elements.
Gender and age data from the Himalayan Database shows that age correlates with increased risk above 50, though experienced older climbers with proper support consistently summit safely. Gender shows minimal difference in base death rate when experience levels are controlled for.

Sherpas and the Everest Death Toll: An Unequal Burden
Any honest discussion of the Everest death toll must address the disproportionate risk borne by Sherpa guides and high-altitude support teams. The 2025 Journal of Physiology research revealed a critical difference in where and when Sherpas die compared with foreign climbers:
- 82.2% of Sherpa deaths occurred during route preparation, not summit attempts
- 76.5% of climber deaths occurred on summit day itself
- The mean altitude of fatal incidents involving Sherpas (6,894 metres) was significantly lower than for climbers (7,970 metres)
This reflects the reality that Sherpas spend far more total time on the mountain than their clients, fixing ropes, carrying loads, and preparing camps across multiple rotations before a single summit attempt. The Khumbu Icefall, crossed dozens of times per expedition by support staff, remains the primary killing ground for Sherpa guides.
The 2014 disaster, which killed 16 Sherpas in a single icefall avalanche and triggered a Sherpa boycott of the 2014 season, forced a reckoning about who bears the costs and risks of commercial Everest climbing. Improved insurance requirements, higher wages, and better safety protocols have followed, though the inherent dangers of the Icefall remain unchanged.
Our article on The Dark Reality of Frozen Bodies on Everest examines the human cost of Everest ambition from perspectives that statistics alone cannot capture.
The 1996 Disaster and Other Landmark Tragedies in Everest’s History
The Everest death toll is not simply a roll of statistics. Behind every number is a human story, and several seasons stand apart as defining moments in the mountain’s history.
The 1996 season claimed 15 lives, including experienced guides Rob Hall and Scott Fischer, whose deaths during a single catastrophic storm were documented by journalist Jon Krakauer in Into Thin Air. The disaster exposed the dangers of commercial climbing when inexperienced clients are pushed beyond their capabilities during rapidly deteriorating weather. Our article 1996 Everest Disaster Re-examined: 7 Shocking Timeline Facts revisits this tragedy with the benefit of historical perspective.
The 2015 earthquake season remains the single most catastrophic event in Everest’s history. A 7.8-magnitude earthquake on 25 April 2015 triggered multiple avalanches, one of which swept through Base Camp and killed 22 people in minutes. The entire 2015 climbing season was cancelled.
Understanding these disasters in context helps prospective climbers and curious readers understand what the Everest mortality rate statistics represent in human terms.

Is Everest Getting Safer? What 2026 Data Tells Us
The honest answer to this question is: yes, but not for everyone.
The peer-reviewed data is clear. The overall Everest mortality rate has approximately halved since 2007. Improved weather forecasting has essentially eliminated weather-related deaths on standard routes. Fixed-rope systems have reduced falls. Better medical protocols and oxygen management have lowered altitude illness fatalities. More experienced climbers now occupy the higher camps.
Yet the 2023 season demonstrated that this progress is fragile and unevenly distributed. When Nepal issued record numbers of permits and low-cost operators flooded the mountain with under-prepared, under-supported clients, the Everest death toll surged to its worst modern level.
The 2026 season began with Nepal’s new $15,000 permit fee in effect and active discussions around requiring proof of prior 7,000-metre ascent experience before issuing Everest permits. Tibet’s side of the mountain already mandates this experience threshold. Whether Nepal adopts equivalent standards will significantly shape the mountain’s safety trajectory in coming years.
The conclusion is clear: Everest has not become safe. It has become better managed for those who choose reputable, well-resourced expeditions. The gap between a safe Everest expedition and a dangerous one has never been wider than in 2026.

10 Frequently Asked Questions About the Everest Mortality Rate
1. What is the current Everest mortality rate in 2026?
The overall mortality rate above base camp is approximately 0.7% for the period 2007 to 2024, down from 1.4% in earlier decades. The normalised rate from 2015 to 2025 stands at roughly 0.69 per 100 climbers, the lowest decade on record.
2. How many people die on Everest each year on average?
Everest yearly deaths average approximately 5 to 8 per year in the modern era. The long-term average from 1921 to 2024 is around 5 to 6 per year. The 2023 season was an outlier at 17 to 18 deaths; 2025 recorded just 5.
3. What is the total Everest death toll to date?
At least 344 confirmed deaths as of the end of 2025, including foreign climbers, Sherpa guides, and support staff. Approximately 200 to 250 bodies remain unrecovered on the mountain.
4. When is climbers most at risk of dying on Everest?
Summit day is the most dangerous phase, accounting for over 76% of climber deaths. The descent from the summit is statistically the most lethal single phase of any Everest climb.
5. Is Everest more dangerous than other 8,000-metre peaks?
Not by percentage. Annapurna I historically had a much higher death rate, and K2’s modern rate remains roughly three times higher than Everest’s. Everest’s well-established routes and commercial support infrastructure make it more survivable relative to its extreme altitude.
6. How does supplemental oxygen affect the Everest death rate?
Dramatically. Climbers without supplemental oxygen face mortality rates historically estimated at 30% or higher. With supplemental oxygen on reputable expeditions, the risk drops to roughly 0.7% in the modern era.
7. Which season was the deadliest in Everest history?
The 2015 earthquake season killed 22 people in a single day. The 2023 season recorded the most deaths in the modern commercial era without a single catastrophic event, with 17 to 18 deaths from isolated incidents across the season.
8. Do Sherpas face different risks to foreign climbers?
Yes. Over 82% of Sherpa deaths occur during route preparation phases, primarily in the Khumbu Icefall, rather than on summit day. Sherpas spend far more cumulative time on dangerous sections of the mountain than clients.
9. What has Nepal done to reduce Everest deaths?
Nepal introduced mandatory guide-to-climber ratios after 2023, tightened permit requirements, and raised the permit fee to $15,000 for 2026. Discussions around requiring prior 7,000-metre experience for all applicants are ongoing.
10. Can I visit Everest Base Camp safely without climbing?
Absolutely. The Everest Base Camp trek to 5,364 metres carries dramatically lower risk than a climbing expedition and is accessible to fit, well-prepared trekkers. See our Trek to Base Camp: Complete EBC Route Guide 2026 for everything you need to plan this adventure.
Final Thoughts: The Mountain Demands Honest Respect
The Everest mortality rate is both better than many people assume and far less forgiving than ambition alone can overcome. At its best, modern Everest climbing is a triumph of preparation, logistics, and teamwork in one of the planet’s most extreme environments. At its worst, it is a collision of commercial pressure, inadequate support, and the unchanging indifference of high altitude.
The Everest death toll of 344 lives is not a deterrent for those genuinely equipped to attempt the mountain. But it is a clear, evidence-based argument for the non-negotiable value of experience, reputable operators, adequate oxygen, and the discipline to turn back when the mountain says no.
Nepal’s mountains offer extraordinary experiences at every level of ambition and fitness.
