E-commerce unit economics
Paid acquisition only works when you know the ROAS floor implied by your costs, refunds, and contribution margin. The break-even ROAS calculator turns those inputs into a single gate you can compare to channel performance.
These tools are built for speed: change an input and the output updates immediately, with no sign-up and no server-side storage of your numbers.
Pair ROAS targets with finance tools (compound interest, mortgage planning) when you are deciding whether to reinvest store profit or pay down debt.
