Calculator
What the Markup Calculator does
Markup Calculator: calculates Profit, Margin % and Markup % from Cost and Revenue / Selling Price. Example: cost 80 ₹ and revenue / selling price 100 ₹ gives profit ₹20.00.
The inputs are Cost and Revenue / Selling Price; the output is Profit, Margin % and Markup %. Set your values, then run the tool to see the result.
Most people who open the Markup Calculator are savers modelling a goal. Getting the arithmetic right before you sign is cheaper than discovering it afterwards.
The work is done by JavaScript already loaded in your browser, so your input never crosses the network.
The field reference, the method and a worked example using the default inputs follow the tool itself.
What do the Markup Calculator fields mean?
The Markup Calculator uses 2 inputs. The page opens in a usable state: real values in, real answer out, ready to edit.
| Field | What to enter | Default |
|---|---|---|
| Cost | measured in ₹ | 80 |
| Revenue / Selling Price | measured in ₹ | 100 |
How does the Markup 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.
Bad input produces an error, never a confident-looking wrong answer.
Worked example
These are the values the Markup Calculator loads by default, and the result it produces from them. Below is the same computation the tool performs on load, step by step.
| Cost | 80 ₹ |
|---|---|
| Revenue / Selling Price | 100 ₹ |
| Profit | ₹20.00 |
|---|---|
| Margin % | 20.00% |
| Markup % | 25.00% |

How to use it
- Key in Cost in ₹.
- Fill in Revenue / Selling Price in ₹.
- Press Calculate.
- Read Profit, Margin % and Markup % in the results panel.
- Copy Link when you want to return to this exact configuration; Print when someone needs it on paper.
What this tool does not do
- Rates are treated as fixed for the whole term; a floating rate will change the outcome.
- Fees, processing charges and taxes are not included unless there is a field for them.
- It handles the common case well and the unusual case literally.
- A plausible-looking answer from the wrong input is still the wrong answer: verify the fields first.
Frequently asked questions
Enter Cost in ₹ and Revenue / Selling Price in ₹. Each field states its unit next to the input, and outputs are labelled the same way.
With the values loaded when the page opens, profit comes out as ₹20.00. Adjust any field to see how much the answer depends on it.
No. Disconnect from the internet and it still works; that is the simplest proof there is no server call.
No charge. Everything on the page is available without signing in.
The arithmetic will match any correct implementation. What it cannot include is the processing fee, the insurance bundled into the offer, or the rate band you actually qualify for.
