About Profit Margin Calculator
Profit Margin Calculator turns any two of cost, revenue, and margin percent into a full pricing breakdown: profit, margin percent, and markup percent, all at once. Fill in cost and revenue to see profit and margin percent, or fill in cost and a target margin to solve for the revenue you need to charge, or fill in revenue and margin to back into your cost. It applies margin = profit ÷ revenue × 100 and markup = profit ÷ cost × 100, and shows both side by side so you can see how the same dollar profit reads very differently depending on which base you divide by. It is useful for pricing a product, checking a vendor quote, setting a service rate, or sanity-checking a markup you were given. Results update as you type, right in your browser — nothing is uploaded. Estimates only — not financial or tax advice.

Example
Input
cost $40, revenue $100
Output
Profit: $60
Margin: 60% (markup 150%)
A $40 cost sold for $100 is a 60% margin but a 150% markup.
Common errors & troubleshooting
- Margin percent and markup percent don't match what a spreadsheet showed. — They are different ratios on the same profit — margin divides by revenue, markup divides by cost. A 60% margin is always a higher markup percent, never the same number.
- Result shows an error when solving for revenue from cost and margin. — Margin percent must be under 100 when solving for revenue from a cost — a 100% margin would mean an infinite selling price. Lower the target margin or fill in revenue directly instead.
- Only one field is filled and nothing calculates. — The Profit Margin Calculator needs exactly two of the three values — fill in a second field (cost, revenue, or margin percent) and the third fills in automatically.
- Markup percent looks unexpectedly small compared to margin percent. — That's expected at low margins — markup and margin converge near 0% but markup grows much faster than margin as the margin percent rises, especially above 50%.
Frequently asked questions
- What does the Profit Margin Calculator compute?
- Given any two of cost, revenue, and margin percent, it computes the missing value plus profit, margin percent, and markup percent — all in one pass.
- What is the difference between margin and markup in this calculator?
- Margin is profit divided by revenue (how much of the sale price is profit); markup is profit divided by cost (how much you added on top of what you paid). The Profit Margin Calculator shows both for the same numbers so you can compare them directly.
- Can the margin calculator solve for the price I should charge?
- Yes. Enter your cost and a target margin percent, leave revenue blank, and the calculator solves for the revenue (selling price) that hits that margin.
- Does the Profit Margin Calculator handle a loss?
- Yes. If revenue is below cost, profit and margin percent come back negative so you can see exactly how much a sale lost, not just that it did.
- Is this margin calculator only for retail pricing?
- No — the same cost/revenue/margin math applies to a single product, a service rate, a project quote, or an entire business line. Enter whichever two figures you know.
- Does the calculator upload my cost or revenue figures?
- No. The Profit Margin Calculator runs entirely in your browser. The numbers you type never leave your device and are not sent to ArrayKit.
