What this calculator does
This crypto profit calculator is built for the moment you need a defensible number — quoting a client, comparing options, or checking someone else's math — not a generic estimate.
The Crypto Profit Calculator answers the only question that matters after a trade: how much did you actually make after fees, and what was the annualized return?
How to use the Crypto Profit Calculator
- Enter your buy price and how many tokens you bought.
- Enter the sell price (or current price for unrealized P/L).
- Add exchange fees on both legs — even 0.5% matters on large size.
- Set days held to see the annualized return.
The formula
profit = (sell × tokens × (1 - sell_fee)) - (buy × tokens × (1 + buy_fee))
Worked example
0.25 BTC bought at $42,000 (0.5% fee) and sold at $65,000 (0.5% fee) → cost $10,552.50, proceeds $16,171.88, profit ≈ $5,619.
Common mistakes
- Forgetting the sell-side fee when setting a target price.
- Comparing raw ROI without annualizing — 50% in 6 months ≠ 50% in 5 years.
- Ignoring tax — short-term crypto gains are taxed as income in most countries.
When to use it
Use for every trade you exit — especially to compare short-term flips against a HODL baseline.

Frequently asked questions
›Does this handle short trades?
For shorts, invert buy/sell so buy price is your entry short and sell price is where you covered.
›What about stablecoin pairs?
Works identically — set both prices in the quote asset.
›Are fees really that important?
On active trading, 0.5% × 2 × 100 trades/year = 100% of a 10% edge. Yes.
›Where does the formula come from?
The formula shown in the "How it works" section is the same one you'll find in standard finance references — no proprietary tweaks or hidden weightings.
›Can I use this on mobile?
Yes — the crypto profit calculator is fully responsive, and results, charts, and the share button all work on phones and tablets.
