ROI is measured as a percentage or dollar?

then your ROI is 100% or 2x.
Ah yeah, this might be true
I'm quite confused if it should be 200% or 100%... I think it should be 200% since we got 200% of the initial investment. $20 is 100% if the initial investment was $20, if we won $40, then that should be 200% return of investment. Am I right?

Our solution to find ROI from initial investment of $20 if we won $40 making it $60 bankroll would be
ROI=40/20 * 100%=200%But if initial investment was $20 and won an extra $20 growing our bank roll to $40 the ROI would be:
ROI=20/20 * 100%=100%
