Built by operators,
not gurus.

ZeroNova started as a set of internal spreadsheets. We were running dropshipping stores, needed quick profit calculations, and got tired of paying $97/month for tools that showed the same math we could do in a spreadsheet.

So we built our own. Clean, fast, no upsells. Every calculator here does one thing and does it right. Create a free account to unlock your results and save calculations for later.

No credit card. No trial period. No "premium tier." Just math that tells you whether a product is worth selling before you spend money on ads.
