About MerchantCalc

MerchantCalc is the all-in-one suite of 22+ e-commerce calculators built to help online sellers make mathematically sound business decisions.

Our Mission

E-commerce has become incredibly complex. Between opaque marketplace fees, fluctuating payment gateway surcharges, unpredictable ad costs, and confusing logistics dimensions, it's harder than ever for a seller to know their true net profit.

Our mission is to bring radical transparency to e-commerce math. We want to empower dropshippers, FBA sellers, Etsy artisans, and wholesale B2B merchants with the exact formulas they need to price their products correctly and avoid selling at a loss.

Why We Are Different

100% Free: No paywalls, no premium subscriptions. The entire 22-tool suite is free forever, supported by display advertising.
Privacy First: Your financial data is none of our business. All math calculations are performed locally in your browser using client-side JavaScript. We never send your revenue, COGS, or margins to a backend database.
Comprehensive: We don't just calculate basic Shopify fees. We calculate your true ROAS, your dimensional CBM weight, and even your Free Shipping thresholds.
