Free E-commerce Calculators
Estimate e-commerce revenue, total entered costs, profit, margin, and blended ROAS from one order-level model.
E-commerce tools ready to use
The e-commerce collection brings unit sales, price, product cost, per-order fees, and advertising spend into one disclosed calculation. It is a planning aid, not an accounting or tax system.
How to use this collection
Model order economics
Multiply units by selling price, then subtract scaled product costs, per-order fees, and ad spend.
Test a pricing scenario
Change one input at a time to understand which assumption changes the resulting margin.
Add omitted costs
Account separately for shipping, refunds, taxes, labor, platform fees, and overhead that are not entered.
Frequently asked questions
Does the calculator store sales figures?
No. The current calculator runs locally and does not transmit or retain the values entered.
Is blended ROAS a profitability metric?
Not by itself. It compares revenue with ad spend and must be considered alongside all other costs.
