They had been making a billion dollars a day with gas and oil exports alone. For a long time. iirc. Although some of that has stopped, it has been restructured elsewhere.
I'm not an expert on Russia finances, especially oil and whatnot, but Reuters puts the figure $8.3bn per month, which would be equivalent to £6.6bn.
To be fair, it is first important to mention this is a fair drop from the revenues gained in the past. Now, even if that figure isn't fully correct, we can work from it.
If it's costing them roughly £1.68bn per week to run the war, so £7-9bn per month, and they're gaining as a minimum £7.4bn per month from revenue...
... you can see it'll really impact on their economy. Even if the revenue is higher, so say £12bn per month, the state is still losing a good few billion per week.
This doesn't even account for the oligarchs/mafia and whatnot who will still want their skim, and will do whatever they can to siphon off their cut.
In simple terms, they're generating less money from oil and gas, and are spending more on the war - their balance book can't be looking great.
Russia's federal budget revenues from oil and gas, the lifeblood of its economy, fell 64% in April from the year-earlier period and declined by 5.9% from March, the finance ministry said on Thursday, as a result of higher subsidies to oil refineries.
