E-commerce
Profit per order, ad targets, pricing, stock, returns, and shipping weight for online sellers.
6 calculators
E-commerce calculators answer the money questions online sellers face on every product. The profit calculator shows what each order really leaves after product cost, shipping, packaging, marketplace and payment fees, and advertising, and the break-even ROAS calculator turns that into the minimum return your ads must earn. The selling price calculator works backwards from the margin you want to the price you need, accounting for fees that grow with the price. On the operations side, the reorder point calculator tells you when to restock and how much safety stock to hold, the return cost calculator puts a number on what returns cost per order, and the dimensional weight calculator shows what your carrier will bill for a box. Every calculator uses your own costs and fee rates, so the results fit your shop whether you sell on your own site or on a marketplace, and nothing you enter leaves your browser.

Open calculatorFrequently asked questions
Do these calculators include Amazon, Etsy, or Shopify fees?
You enter your own fee rates. Marketplace and payment fees differ by category, plan, and country and change over time, so using the rates from your own account keeps the results accurate.
Which calculator should I start with?
Start with the profit calculator to see what one order earns before and after ads. Then use break-even ROAS to set your ad targets, and the selling price calculator if the margin is too thin.
Can I use these for wholesale or B2B orders?
Yes. Leave marketplace fees at zero and enter your own payment terms and shipping costs. The reorder point and dimensional weight calculators work the same for any kind of stock.
