Product Cost & Profit Calculator
Estimate what each product may earn you. This printable Product Cost & Profit Calculator walks you line by line through what the customer pays, what each sale really costs you (product, packaging, postage, selling fees, payment processing, advertising) and what you actually keep.
It includes the formulas for profit, margin, markup and break-even, plus a simple target-margin pricing method so you can set prices with confidence instead of guessing.
