Enter the price you bought at (entry), the current price, and the quantity you hold. If your exchange charged fees, add them as a total amount. The calculator returns your cost basis, current position value, and PnL in both currency and percent.
Crypto PnL: how to calculate gains and losses (amount and %)
A crypto PnL calculator helps you understand how your position is performing by computing the difference between what you paid and what your holdings are worth now. “PnL” stands for profit and loss. In everyday investing, people often want two results: the PnL amount (how much you gained or lost in currency) and the PnL percentage (how large the gain or loss is relative to your initial cost). This tool focuses on clear, practical numbers so you can check a trade, compare multiple entries, or track the impact of market moves without needing an exchange dashboard.
The core logic is simple. First, compute the cost basis (what you actually spent): cost basis = entry price × quantity + fees. Fees are optional, but they matter because they reduce net performance. Next, compute your position value: position value = current price × quantity. Finally, compute profit or loss: PnL = position value − cost basis. If this value is positive, you are in profit; if it is negative, you are in loss.
For the percentage, the calculator uses: PnL % = (PnL ÷ cost basis) × 100. This expresses performance relative to what you put in. As a quick example, if your cost basis is 1,000 and your current position value is 1,150, then PnL is +150 and PnL % is +15%. If the value drops to 900, PnL is −100 and PnL % is −10%. These numbers are helpful for comparing positions of different sizes, because percentage returns are scale-independent.
This calculator runs locally in your browser and does not fetch live quotes, which makes it fast and private. Because it is a simple estimator, it does not include taxes, funding rates, interest, liquidation costs, or spread/slippage. For real trading decisions, always confirm the final prices and fees on your exchange. Still, for day-to-day tracking, journaling trades, or quickly checking a scenario, a local PnL calculator is often the fastest way to get clean results.
What is this crypto PnL calculator used for?
This crypto PnL calculator is a performance measurement tool. It helps you understand how a crypto position has evolved by calculating profit or loss both in absolute value and percentage, based on prices and quantity. It is intended for analysis, tracking, and learning purposes only.
Who is this tool useful for?
- Crypto holders who want to check how a position is performing
- Traders comparing different entry prices or scenarios
- Investors tracking gains and losses over time
- Learners discovering how PnL calculations work
Concrete examples
- Checking whether a position is currently in profit or loss
- Comparing two different entry prices for the same asset
- Understanding how fees impact overall performance
Common mistakes to avoid
- ❌ Ignoring trading or transaction fees
- ❌ Confusing profit amount with profit percentage
- ❌ Forgetting that unrealized PnL can change at any time
PnL figures are snapshots based on prices at a given moment and can fluctuate with market conditions.
Limits and important notes
This calculator does not account for taxes, funding rates, interest, leverage effects, liquidation risk, or market liquidity. It does not provide financial advice or investment recommendations. Always confirm official figures directly on your exchange or records.
