Conversion rate calculator

Every other lever costs money. More traffic means more ad spend, a higher average order value usually means discounting something else, and a better margin means renegotiating with a supplier. The conversion rate is the one number where the gain is free once the work is done: the same visitors, the same products, the same budget, and more of them buy.

That is also why the arithmetic looks so aggressive. A store doing €1M a year at 1.4% that reaches 2.1% is not 0.7 percentage points better, it is 50% bigger. The percentage-point gap reads as small and the revenue gap does not.

It will not tell you whether the new rate is achievable on your store. That depends on your category, your price point, how much of your traffic is paid, and where the leaks actually are. A store at 0.6% usually has one broken thing and a fast fix; a store at 2.4% is fighting for a tenth of a point at a time.

It also assumes the extra conversions are as valuable as the current ones, which is not always the case: aggressive discounting lifts the rate and lowers the margin at the same time. Measure revenue per visitor alongside the rate, not instead of it.
