Hey Product Hunt! I'm Adam, a performance and affiliate marketer.
I kept rebuilding the same spreadsheets: break-even ROAS, the max CPA a campaign can survive, which affiliate offer actually pays more per click. Most free calculators online give you a number with no context, sit behind a signup wall, or quietly use the wrong formula (margin vs. markup trips up a lot of people).
So I built GrowthMath:
- 11 calculators, free, no signup
- Everything runs in your browser - even the Dormant Affiliate Finder, which reads your CSV locally and never uploads it
- Every tool shows the formula, typical benchmarks and what the result means
My favourite is the ROAS calculator: it shows your break-even ROAS from your margin, so you can see when a green-looking 3x campaign is actually losing money.
What calculator do you keep rebuilding that should be next? I'm picking the next tool from this thread.
