E-Commerce & Retail Calculators (38)
Selling online means juggling fees from every direction, which is why this set of retail calculators starts with a sales tax calculator for what you actually owe on an order, alongside dedicated fee calculators for eBay, Etsy, and Amazon FBA, a Shopify transaction fee tool, and a side by side Etsy versus eBay versus Shopify fee comparison. PayPal and Stripe processing fees get their own calculator too, so you know exactly what a payment platform keeps before the rest hits your account.
Once the sale is made, a profit margin calculator and a markup calculator show what you actually kept, an inventory turnover calculator and a reorder point tool keep stock levels realistic, and a ROAS break even calculator tells you whether an ad campaign is actually paying for itself. Round it out with shipping calculators for Etsy, eBay, Shopify, freight, and international dropshipping, a unit price calculator with versions for wholesale, Amazon bulk buying, and manufacturing cost per unit, plus AOV and upsell revenue, coupon impact on margin, Black Friday revenue forecasting, cost of lost customer, affiliate commission and CAC, and brand ambassador program ROI.
