Ukraine’s total war costs will reach $155 billion this year, while the government is trying to close a $27 billion gap in 2026 military spending to support combat operations at the start of 2027, Prime Minister Sergii Koretskyi said. Kyiv plans to cover $7 billion by postponing expenditure, reallocating funds within the budget and cutting costs, while seeking partners to finance the remaining $20 billion. The estimate is Ukraine’s first public calculation of annual war costs, so there is no comparable figure for 2025. It includes domestic state spending and military aid from Western allies delivered as hardware, including air-defense missiles, ammunition and aircraft. Ukraine’s total budget revenues are targeted at about $70 billion this year and are fully allocated to defense. Koretskyi said $29.5 billion in foreign aid was at risk if Kyiv does not meet reform commitments to the IMF (International Monetary Fund) and the EU by Oct. 15. The funding pressure comes as Russia plans to spend 17.1 trillion roubles, or $202.58 billion, on defense in 2027, about 27% above its original 13.5 trillion-rouble budget and the highest level since its invasion began in February 2022. Ukraine is still finalizing next year’s military spending plans and has faced delays in receiving foreign aid because of reform implementation problems, corruption scandals and disputes between the government and parliament over unpopular legislation.
