- Russia has likely incurred approximately 950,000 casualties (killed and wounded) since launching the full-scale invasion of Ukraine in 2022.
- In the first four months of 2025, Russia likely sustained approximately 160,000 casualties. Should these casualty rates persist for the rest of 2025, this would be the costliest year of the war in terms of Russian personnel, continuing the year-on-year trend of casualty increases.
- The average daily Russian casualties during April 2025 was just over 1,200, and totalled 36,000 over the course of the month, according to Ukrainian General Staff reporting. This was a moderate decrease from the daily average of 1,300 in March 2025.
- Whilst the numbers of casualties remain below the very high daily rates of nearly 1,600 in late 2024, when Russia was making territorial gains, it is still towards the high end in the overall context of the conflict. So far in 2025, Russia has not been able to translate continued heavy losses into significant advances in Ukraine.
