Russia sustained approximately 415,000 casualties in its war against Ukraine throughout 2025, the UK Ministry of Defence reported, citing intelligence data. This represents a slight decrease from the roughly 430,000 casualties recorded in 2024, which remains the highest annual toll since the full-scale invasion began.
The total casualty count since February 2022 has reached approximately 1,213,000 killed and wounded, according to British intelligence estimates.
December 2025 saw Russian forces losing an average of 1,130 soldiers daily, according to Ukrainian General Staff figures cited in the British report. This marked an increase from 1,030 casualties per day in November and represented the fourth consecutive monthly rise.
However, the period from August through December 2025 recorded the five lowest monthly average casualty rates since April 2024, the intelligence update noted.
"Russia's monthly casualty rate has risen again in conjunction with increasing advances across the frontline," the Ministry of Defence stated. "Russia will highly likely continue to experience high casualty rates over January 2026 with continued dismounted infantry attacks on multiple axes."
The Ukrainian General Staff reported that as of 14 January, Russian military losses since the invasion began totaled approximately 1,221,940 personnel.
Moscow has not officially disclosed its casualty figures since September 2022, when it claimed 5,937 killed.
