Free Tools
Calculators and audits for
Amazon operators.
Four free tools we built for our own brands. Run the numbers on ad spend, FBA fees, subscription margins, and your listing, in a couple of minutes each.
Numbers, not theory
The same math we run before we touch a brand's account.
Every one of these tools answers a real operator question we get asked all the time. What ad spend can I justify? What will FBA take out of this product? Does a subscription discount pay off? Is my listing actually built to convert? They run in your browser, free, with no number ever leaving your screen.
