What the Profit Margin Calculator does
Profit Margin Calculator: calculates Profit, Margin % and Markup % from Cost and Revenue / Selling Price. Example: cost 80 ₹ and revenue / selling price 100 ₹ gives profit ₹20.00.
From Cost and Revenue / Selling Price, this tool derives Profit, Margin % and Markup %. Enter what you need and trigger it when you are ready.
It is mostly used by people planning a budget. Lenders present the same deal in different ways, so a like-for-like number is worth having.
The work is done by JavaScript already loaded in your browser, so your input never crosses the network.
The method, a field-by-field reference and a worked example built from the defaults are all on this page.
What do the Profit Margin Calculator fields mean?
The Profit Margin Calculator uses 2 inputs. The form opens pre-filled, so the fastest way in is usually to overwrite the one field you actually care about.
| Field | What to enter | Default |
|---|---|---|
| Cost | measured in ₹ | 80 |
| Revenue / Selling Price | measured in ₹ | 100 |
How does the Profit Margin Calculator work?
Each output is derived from the inputs above in a single pass; there is no hidden state carried between runs, so the same inputs always give the same calculation.
The guard clauses run before the formula does, which is why mistakes surface next to the field.
