₿ Crypto Tax Estimator
Estimate capital gains on a crypto sale using FIFO purchase lots. Educational only, not tax advice.
Sensitive finance note
- Use rounded or anonymized figures if exact records are not needed for the estimate.
- This is an educational calculator, not tax, legal, accounting, or financial advice.
Why it is useful
It helps investors sanity-check possible tax exposure before using official records, tax software, or a qualified professional.
How it works
Enter purchase lots and a sale. The tool consumes the oldest lots first, allocates basis and fees, and estimates gain or loss.
Best input
Use exchange and wallet exports with dates, quantities, cost basis, and fees. This tool handles a single sale scenario.
Recordkeeping tip
Keep raw exports and transaction IDs because crypto tax treatment depends on complete history and jurisdiction.
Privacy note
Entered values are calculated locally in your browser.
Important limitation
This is not tax, legal, accounting, or financial advice. It does not handle every DeFi, staking, transfer, wash-sale, or jurisdiction-specific rule.
Quick answers
Is this enough to file taxes?
No. Use tax software or a qualified professional for filing.
