Russia's invasion of Ukraine has cost Moscow a small amount by historical standards, per the Economist. Russia's spending remains opaque, but its war budget is about 3% of GDP. The direct fiscal cost of the war — spending on soldiers and machines — is estimated to be about 3% of Russia's GDP, or roughly $67 billion a year, according to the report. That figure comes from a comparison of Moscow's pre-invasion spending forecasts for defense and security with what it actually spent. However, 3% is substantially higher than the 0.4% of GDP the Soviet Union spent on its war on Afghanistan.
