Be careful of the goal. Sanctions are unlikely to directly bring someone to the bargaining table. Sanctions make is harder to get the things Russia needs to fight way. It will take years to catch up, but Russia has a smaller economy. Russia has mostly stopped using tanks because they can only make a few of them (1-3 per day depending on what source you ask), and they have no ability to make more, sanctions are part of this.

The real question is what if there were none - Russia would have more money and thus have done a lot more damage to Ukraine - but there is no way to measure damage they could have done.
