Profit Calculator
Cost and selling price in: profit or loss, profit margin and markup percentage out — the pricing numbers sellers mix up, sorted live.

Profit Calculator
Enter what an item cost you and what you sell it for, and get the absolute profit (or loss) plus the two ratios every seller needs: margin — profit as a share of the selling price — and markup — profit as a share of the cost.
Because the two ratios use different denominators, a 25% margin is a 33.3% markup; the tool shows both together so invoices, quotes and pricing sheets stay consistent.
Frequently asked questions
What is the difference between margin and markup?
Margin is profit ÷ selling price (share of revenue); markup is profit ÷ cost (amount added on top of cost). A product bought for 80 and sold for 100 has a 20% margin and a 25% markup. Confusing the two silently shrinks your intended profit.
How do I set a price from a target margin?
Divide the cost by (1 − target margin): for a 25% margin on an 80 cost, 80 ÷ 0.75 ≈ 106.67. Setting it by markup instead (80 × 1.25 = 100) leaves you with only a 20% margin.
Does the calculator include fees and taxes?
It works on the two numbers you enter, so payment-processing fees, shipping and sales tax only show up if you fold them into cost or price first. For tax-inclusive pricing, run the number through the VAT or GST calculator.
