How to use the crypto tax calculator
Prepare the values for this calculation
Estimate tax on a crypto gain using an explicitly entered tax rate. Use the formula below to check that it answers your question. Read the input units before transferring figures from a statement, measurement or dataset.
Enter and check each input
- Sale proceeds: enter a value at least 0. Use the unit named in the label or selected above. Do not leave this required field blank.
- Cost basis: enter a value at least 0. Use the unit named in the label or selected above. Do not leave this required field blank.
- Transaction costs: enter a value at least 0. Use the unit named in the label or selected above. Do not leave this required field blank.
- Tax-rate assumption (%): enter a value at least 0 and no more than 100. Use the unit named in the label or selected above. Do not leave this required field blank.
The input table gives a complete example. Keep units and time periods consistent across related fields.
Calculate and resolve any input error
Choose Calculate after entering the values. Changes also update the answer after a short pause. If an error appears, follow its message, correct the field and calculate again. Reset restores the example values.
Interpret the answer
Check Estimated tax on gain first. With the unchanged example inputs, it is $980.00. Compare the additional metrics with the primary result; each has its own label and unit.
Compare and keep a useful result
For a controlled comparison, keep every other example input unchanged and change Sale proceeds from 15000 to 16500. The resulting Estimated tax on gain is $1,280.00. This illustrates the equation’s response to that input, rather than a forecast of real events.

Crypto Tax Calculator formula
Gain=proceeds−cost basis−transaction costs; estimated tax=max(gain,0)×entered rate.
Inputs and units
| Input | Format / range | Example |
|---|---|---|
| Sale proceeds | minimum 0 | 15000 |
| Cost basis | minimum 0 | 10000 |
| Transaction costs | minimum 0 | 100 |
| Tax-rate assumption (%) | minimum 0; maximum 100 | 20 |
Worked example
Using the example inputs above, the estimated tax on gain is $980.00.
- Estimated tax on gain
- $980.00
- Modeled gain/loss
- $4,900.00
- Entered tax rate
- 20%
Results and assumptions
Actual taxable gain, holding period, losses, lot selection, jurisdiction and reporting rules may differ.
Fix an input or unexpected result
Sale proceeds is required. Enter sale proceeds using the format and bounds in the input table. Zero and an empty field are different: use zero only if it is allowed and represents your data.
If your answer differs from the example, choose Reset and compare every field, including selected units and options. Check percentage versus decimal entry and whether values describe the same period. Round only the final displayed answer when reproducing the formula.
If a discrepancy remains, report the calculator issue with the page address, non-sensitive example inputs, actual result, expected result and a reference for your calculation.
