The Human and Material Cost of Russia's War on Ukraine

A data-oriented assessment of losses on both sides since Russia's full-scale invasion began on February 24, 2022, drawing on multiple Western intelligence agencies, independent open-source trackers, and international institutions.

Russian Military Personnel Losses

The highest-profile running tally comes from Ukraine's own General Staff, which reported on May 4, 2026 that Russia has suffered approximately 1,336,120 total military casualties, combining killed and wounded, since the full-scale invasion began. The figure includes 970 casualties that Russian forces suffered in a single day. Ukraine updates this number daily, though the methodology is not independently verified.

The figure aligns broadly with estimates from Western governments and intelligence services. The UK Ministry of Defence put Russia's killed and wounded at approximately 1,168,000 as of December 2025. Former CIA director William Burns, in a January 2026 Financial Times interview, cited 1,100,000 casualties. Western officials reported by Bloomberg in February 2026 estimated 1,200,000 Russian casualties, including 430,000 in 2024 alone and 415,000 in 2025.

The January 2026 CSIS report, one of the most comprehensive Western analytical assessments, estimated 1,200,000 Russian military casualties, killed, wounded, and missing, with as many as 325,000 killed between February 2022 and December 2025. The Wall Street Journal reported in February 2026 that Russia had suffered approximately 1,200,000 casualties including 325,000 killed, while the Netherlands' Military Intelligence and Security Service estimated in April 2026 that Russia had suffered about 1,200,000 permanent losses, including more than 500,000 dead.

Multi-Source Comparison: Russian Casualties

Confirmed deaths tracked independently through obituaries and social media provide only a partial picture. The Mediazona and BBC open-source project had documented over 200,000 identified Russian deaths by February 2026, a number widely understood to be a significant undercount, as many deaths go unannounced or are suppressed by Russian authorities.

In March 2026, Ukrainian intelligence released a striking figure based on captured Russian documents. President Zelenskyy and Ukrainian military intelligence chief Lieutenant General Oleh Ivashchenko stated that according to Russian documents obtained by Ukrainian intelligence networks, approximately 1,315,000 Russian soldiers had been killed or wounded since the start of the invasion. Zelenskyy said even these figures were "understated."

The rate of Russian losses has not slowed. In April 2026, Zelenskyy stated that Russia had suffered its highest single-month losses since the invasion began, with over 35,000 killed or wounded in March alone.

Ukrainian Military Losses

Ukraine's military casualties remain far less certain. Kyiv has not released official figures, citing operational secrecy, but various estimates have emerged. In late February 2025, Zelenskyy announced that over 46,000 Ukrainian soldiers had been killed and 380,000 wounded, noting that approximately 50% of the wounded had recovered and returned to active duty. He updated the figure in February 2026, stating that 55,000 Ukrainian soldiers had been killed.

The CSIS January 2026 report gave a broader range. It estimated that Ukraine had suffered between 500,000 and 600,000 total military casualties, killed, wounded, and missing, from February 2022 to December 2025, with between 100,000 and 140,000 killed in action. Radio Free Europe/Liberty's February 2026 estimate aligned, also placing Ukrainian military losses at 500,000 to 600,000 killed, wounded, or missing. The Netherlands' Military Intelligence Service's April 2026 assessment estimated Ukraine had suffered approximately 500,000 permanent losses.

The UALosses project, an independent name-by-name tracking effort found reliable by Mediazona, Meduza, BBC News Russian, and The Economist, had documented by name the deaths of 91,559 Ukrainian fighters as of April 8, 2026, as well as 95,165 missing in action, for a total of 186,724 dead or missing. This is considered a significant undercount given incomplete reporting.

The Casualty Ratio

The casualty ratio consistently favors Ukraine. CSIS estimates the ratio to be roughly 2:1 or 2.5:1 in Ukraine's favor. The Economist estimated approximately five Russian soldiers die for every Ukrainian killed. A key caveat applies: Russia is a country of 144 million drawing on far larger reserves, and its capacity to absorb losses and regenerate forces has been a defining feature of the conflict.

Civilian Casualties

Civilian deaths have mounted throughout the war. The UN's Office of the High Commissioner for Human Rights (OHCHR) verified a total of 58,930 civilian casualties through March 2026, of whom approximately 15,578 were killed and 43,352 injured. OHCHR consistently notes the real toll is higher, as deaths in occupied or frontline zones cannot be confirmed.

The first quarter of 2026 saw civilian casualties 20 percent higher than the same period in 2025, with 556 killed and 2,731 injured in just three months. March 2026 was the deadliest month for civilians since July 2025, with at least 211 killed and 1,206 injured, representing increases of 49 percent over February and 29 percent over March 2025.

Attacks with long-range weapons, missiles and drones, remained the primary cause of civilian casualties, accounting for 36 percent of the total, with most occurring in cities far from the frontline. Short-range drones were the second leading cause of civilian deaths, particularly near frontline areas.

Independent researchers estimate the true civilian death toll is considerably higher than UN-verified figures. Political scientist Neta Crawford estimated 323,000 total dead in the war by July 2025, across military and civilian categories, at an average rate of 7,690 killed per month, far exceeding the monthly death rates in the Gaza war or the War in Afghanistan.

The war has also produced a catastrophic medical toll. The National Health Service of Ukraine recorded 95,000 amputations performed in-country by August 2025, with the total including procedures performed outside Ukraine estimated as high as 120,000.

Russian Equipment Losses

Ukraine's General Staff tracks Russian equipment losses daily. As of May 5, 2026, the running totals reported are as follows:

Independent open-source tracking organization Oryx, which requires photographic or video evidence for each confirmed loss, provides a more conservative but rigorously verified count. As of early 2026, Oryx documents approximately 3,500 or more Russian tanks destroyed, damaged, abandoned, or captured, the highest confirmed tank loss of any conflict since World War II. Since the invasion began, Oryx has documented the visually confirmed loss of over 21,550 pieces of Russian military equipment in total. Because Oryx requires photographic confirmation, its figures are widely understood to significantly undercount actual losses.

These confirmed losses represent roughly 50 to 60 percent of Russia's pre-war tank inventory. Russia has compensated by drawing on Soviet-era stored equipment, thousands of T-62, T-72, and T-80 tanks from warehouses, and through significantly increased domestic military production, estimated at over 1,500 tanks per year and more than 3 million artillery shells per year.

Ukrainian Equipment Losses

WarSpotting, an independent visual tracker similar to Oryx, documents Ukrainian confirmed losses. As of early May 2026, it recorded 3,701 Ukrainian tanks lost, 8,300 infantry fighting vehicles, 932 self-propelled artillery pieces, 382 towed artillery systems, 105 fixed-wing aircraft, and 110 helicopters. As with Russian figures, actual losses are believed to exceed confirmed totals.

Territorial Context

The scale of losses must be understood against what has actually been gained and lost on the ground. Since February 24, 2022, Russia has seized approximately 29,171 square miles of Ukrainian territory, about 13% of the country, an area roughly equivalent to half the state of Illinois. Including Crimea and the Donbas seized before 2022, Russia now controls approximately 45,796 square miles, or about 20% of Ukraine's territory.

Progress has been extremely slow relative to losses. From October 2025 to March 2026, Russia captured roughly 746 square miles, an average of about 4.1 square miles per day, down from approximately 5.7 square miles per day over the same period a year earlier.

The Scale in Historical Perspective

Russia has absorbed over a million casualties in pursuit of territorial gains measured in dozens of square miles per month. Ukraine, though far smaller, has matched and in key metrics exceeded expectations, sustaining a front against a nuclear-armed neighbor now in its fourth year of full-scale warfare.

Ukraine has suffered deeply too. With 55,000 or more soldiers killed by Zelenskyy's own account, possibly as many as 140,000 by CSIS estimates, along with the near-total destruction of its energy infrastructure, the displacement of millions of its citizens, and an economy kept alive by Western financial support, the cost to the defending nation has also been historic. At least 15,578 verified civilian deaths represent a fraction of the true toll, by every credible account.

As of May 5, 2026, with no ceasefire in place and daily losses continuing on both sides, the full accounting remains ongoing.
