Open the calculator

Each calculator answers one question about your store: how many visitors buy, what a higher conversion rate is worth, how much you keep from each sale and whether a test result is real. They use your own numbers and run in your browser. We don't store anything you enter.

The benchmarks on these pages come from named sources with dates, such as Littledata's Shopify conversion rate median. Use them as reference points, and compare with your own past months first.

These calculators are free and work for any store. PopupSnap's popups run on Salla and Zid, the spin-to-win wheel and countdown timers on Salla, and InstaFeed also on WooCommerce and any website. See what runs on your store.
