Estimate crypto gains using FIFO
Working out capital gains on crypto means matching sells to buys, and the first-in-first-out method is a common approach. This calculator estimates gains using FIFO lots from your buy and sell trades, entered in a simple CSV-style form.
Why FIFO and lot matching matter
When you sell crypto, the gain depends on which purchase it is matched against, because different buys had different prices. FIFO matches each sale to your earliest un-sold coins first, which is a standard method many tax regimes accept. Doing this by hand across many trades is error-prone, since each sale draws down the oldest lots and you must track what remains. The calculator applies FIFO consistently so the gain estimate is coherent across all your trades.
A coherent gain estimate
This is an estimate for planning from the figures you enter, not financial advice, and real outcomes depend on rates and rules that change.

Frequently Asked Questions
What is FIFO for crypto gains?
First-in-first-out: each sale is matched against your earliest un-sold coins first. The gain is the sale price minus the cost of those earliest lots.
Why does the matching method matter?
Because different purchases had different prices, so which buy a sale is matched against changes the gain. FIFO is a standard, widely accepted method.
Why is this hard to do by hand?
Because each sale draws down the oldest lots, and you must track what remains of each purchase across many trades. The calculator does this consistently.
Is FIFO the only method?
No, but it is common and accepted in many tax regimes. Confirm which method applies to you before relying on the figure.
Is this tax advice?
No. It is an estimate. Confirm your crypto tax obligations with a professional.
