• The 20% figure represents an approximation; some sources cite slightly lower figures such as 'almost 20%' as of 2024. Russian territorial gains in 2025 amounted to approximately 0.72-0.94% of Ukraine's total territory according to conflict monitoring organizations.
• The percentage includes territories occupied since 2014 (Crimea and parts of Donbas) as well as territories occupied since the February 2022 full-scale invasion.
• Different methodologies for calculating occupied territory may yield slightly different percentages depending on whether certain contested areas or administrative boundaries are included.
