How to use it
Numbers are clearer when the assumptions are visible.
Start with the default example. Change one input at a time and notice which part of the result moves. Then read the explanation below before using any real-world number.
- Use your account currency consistently.
- Include costs and uncertainty outside the simple model.
- Verify the product’s own contract or fee rules.
What the calculator includes
The gross result is the difference between the exit and entry price multiplied by quantity. The tool then estimates fees as a percentage of the buy and sell turnover. ROI is shown against the initial purchase value, so you can see how costs change the headline return.
The model does not include taxes, network fees that are not represented by the percentage field, funding, currency conversion, spread differences or slippage. Add a margin of safety and verify the venue’s fee schedule before using real figures.
Working modelNet result ≈ (sell − buy) × quantity − estimated fees
Use it as a question generator
Try the same prices with a smaller quantity, a wider spread or a different fee. Notice how a positive gross move can become much smaller after costs. Then ask what happens if the exit is lower than expected; the calculator is most useful when it makes downside visible too.
Do not use the output to decide what to buy. Use it to check whether you understand the units, the fee basis and the possible range of outcomes.
Common questions
Before you move on
Does the result include taxes?+
No. Tax treatment depends on your country, account and activity. Seek local advice.
Does it use live crypto prices?+
No. It uses the values you enter and is designed for learning scenarios.
Why is my exchange result different?+
Actual fees, spread, slippage, quantity precision, funding and conversion can differ from this simplified estimate.
