Show HN: I made Amazon Profit Calculator, Visual Tool to Estimate Amazon Profits
monkeycalcs.comI made a profit calculator for Amazon sellers that breaks down FBA fees, ROI, and net profit per unit.
You plug in your product price, shipping, and costs. It gives a full breakdown of gross revenue, Amazon fees, taxes, and final margins. Everything updates live as you type.
It runs in the browser, no signups, no tracking. Just a tool I needed and ended up putting online.
