About mQuickCalc Finance — Fee & Profit Calculators
mQuickCalc Finance provides free fee, margin and revenue calculators for sellers and creators. Our methodology, data sources and platform coverage.
What this site is
mQuickCalc Finance (finance.mquickcalc.com) is a free suite of fee, margin, profit and revenue calculators for online sellers, creators, freelancers and side-hustlers. We cover marketplaces, payment processors, creator platforms, pricing math and everyday finance — with every calculation running privately in your browser.
Why you can trust the numbers
- Fee logic is checked against each platform’s publicly published rate structure.
- Tools are transparent: the assumptions behind each result are shown on the page.
- Corrections are verified against the platform’s published help pages before deployment.
- Independent tools — we are not affiliated with Etsy, eBay, Amazon, Shopify, Stripe, PayPal or any named brand.
Privacy by design
Every calculator runs in your browser. We do not store the numbers you enter on our servers, and as of this writing we run no third-party advertising. See our Privacy Policy.
