The war in Ukraine is costing Russia about 20 Billion Euro per day. After one month that is about 600 Billion Euros. Admittedly, much of this is sunk cost (spend from previous years tied up in equipment)
On February 24th 2022, Russia launched a full-scale invasion of neighbouring Ukraine.

Russia’s military spend is a little over $60 Billion USD per year (4% of GDP). So, in 30 days they have burnt through 10 years of annual spending. The sanctions are going to hurt Russia’s GDP. It will shrink making future military spending at current L dollar levels difficult to sustain. Sooner or later Putin is going to have to weigh the dollar costs of the war as his forces become smaller and smaller through destruction and capture and his economic ability to replace them is also diminishing. And, various NATO countries that were previously not making their 2% GDP target have vowed to increase spending.
Putin’s goal was to strengthen Russia and weaken NATO. Russia is now getting weaker and NATO stronger. Colossal strategic decision making error to invade Ukraine.
