Bitcoin to US Dollars Profit & Loss Calculator
What this tool estimates
This page estimates historical profit or loss for Bitcoin (BTC) positions priced in US Dollars (USD). It is the most common crypto-to-fiat pairing and the one most investors check first when reviewing past trades, evaluating exit timing, or preparing rough estimates before tax season.
Add one or more transactions with buy and sell dates to see estimated gain per row. Because Bitcoin is the highest-value and most liquid cryptocurrency, even small timing differences between buy and sell dates can produce significant dollar swings. This tool helps you see that impact without logging into an exchange or opening a spreadsheet.
Not included: trading fees, slippage, intraday price variation, staking rewards, gas costs, or jurisdiction-specific tax rules. Treat output as a directional estimate and reconcile with exchange records for official reporting.
| Amount | Crypto | Fiat | Buy Date | Sell Date | Profit/Loss (USD) |

How it works
For each row, the calculator requests historical rates for buy and sell dates via /.netlify/functions/crypto-convert, then computes (sellRate − buyRate) × amount in USD. Arithmetic runs client-side after the rate is returned.
Data source: historical daily reference rates from CoinGecko API. Intraday timing, exchange-specific spreads, and fees are not included.
Scope: this tool estimates gain/loss per position. It does not implement FIFO/LIFO/HIFO lot methods, tax event classification, staking treatment, or jurisdiction-specific reporting.
Practical use scenarios
- Test how a BTC position performs in USD terms across two different exit dates.
- Prepare a directional investor update using transparent date-based assumptions.
- Use row-by-row output to isolate which transaction contributed most to total movement.
- Compare multiple transaction rows to see timing impact under one fiat baseline.
- Perform a pre-tax estimate review before handing records to professional tools.
Planning notes
- Before tax season, compare multiple sell dates to test sensitivity for this pair.
- Use this route for quick hindsight checks before full ledger reconciliation.
- If fees were charged in asset units, reconcile exchange statements after using this estimate.

FAQ
This tool uses daily reference rates from CoinGecko, which may differ from the exact price your exchange executed at. Exchanges also apply their own fees and spreads.
Only as a preliminary estimate. US tax reporting requires complete transaction records including fees, cost basis method (FIFO, LIFO, etc.), and exchange-specific data that this tool does not capture.
BTC is highly volatile. A one-week difference in sell date can swing the result by thousands of dollars on even moderate positions. This tool helps you see that timing impact.
You can add multiple rows to model different positions, but the tool does not connect to any exchange. You enter dates and amounts manually.
