This margin calculator helps ecommerce sellers, operators, and pricing teams check how much gross profit is left after cost and what that means as a percentage of selling price. It is useful because margin and markup are often confused, but both matter when pricing products, bundles, and promotional offers.
Formula and method
The calculator subtracts total cost from selling price to estimate gross profit, then divides that profit by selling price for margin and by total cost for markup. It also shows cost share as the percentage of price consumed by cost.
Example
If a product sells for $49.99 and total cost is $35.00, the calculator estimates gross profit, gross margin, markup, and the share of price consumed by cost.
