What is a crypto tax calculator?
Come tax season, the question is: what were my realised gains? This calculator estimates them from your trade history using FIFO or LIFO cost basis — matching sells against buys to compute the gain or loss on each disposal, then totalling it. It's an estimate to help you understand your position (not tax advice), runs in your browser, and keeps your trades on your device. Describe it and Cryptohopper.AI builds it.
Common features
- Realised gains/losses from your trade history
- FIFO or LIFO cost-basis matching
- Per-disposal and total gain/loss
- Optional short vs long-term split
- Trades stay on your device
- 100% browser-side, no key
Real-world examples
FIFO total
Enter trades and see realised gains under FIFO.
FIFO vs LIFO
Compare the two methods' impact on your gain.
Per-trade detail
Inspect the gain on each individual disposal.
Why Cryptohopper.AI fits crypto tax calculator projects
Cryptohopper.AI builds the cost-basis engine from a description, kept private on your device. Add CSV import or a tax-year filter by chatting. (Estimate only — not tax advice.)
