I know that if you want to figure out your roi you divide your profits or losses by the total cost of the buy-ins and multiply by 100. But what is the math procedure if you know your ROI but want to fiure out your actual dollar profits or losses? Thanks.

Profit = total invested x ROI

eg you played 20 tournaments, each costing a total of $5.25 (including rake), and your ROI is 4.5%

Then your total profit = 20 x $5.25 x (4.5/100)

=$4.725
