Ethereum to Euros Profit & Loss Calculator
What this tool estimates
This page estimates historical profit or loss for Ethereum (ETH) positions priced in Euros (EUR). It serves European holders who need a euro-denominated view of their ETH trades for personal review, portfolio updates, or preliminary tax planning.
Add one or more transactions with buy and sell dates to see estimated gain per row. Like the BTC-to-EUR pair, the result reflects both ETH price movements and EUR/USD dynamics, so euro-denominated gains can diverge noticeably from dollar-denominated ones.
Not included: gas costs, DeFi yield, staking rewards, NFT proceeds, or EU member-state-specific tax rules. Treat output as a directional estimate and reconcile with exchange and wallet records for official reporting.
| Amount | Crypto | Fiat | Buy Date | Sell Date | Profit/Loss (EUR) |

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 EUR. 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 ETH position performs in EUR terms across two different exit dates.
- Run a quick realized P/L estimate before reconciling full exchange exports.
- Estimate gain/loss before deciding whether to realize or defer a position.
- Check downside sensitivity by moving sell date to a lower-price window.
- Create draft month-end performance notes before accounting system close.
Planning notes
- When reporting internally, include date ranges used for this pair.
- Use this route for quick hindsight checks before full ledger reconciliation.
- If portfolio base currency is EUR, this pair helps evaluate realized outcomes.

FAQ
No. Gas fees are transaction-specific and not captured by daily reference rates. Subtract your actual gas costs for a more accurate net figure.
The EUR/USD exchange rate adds a second variable. If the euro strengthened against the dollar during your holding period, your euro profit will be smaller than the dollar equivalent, and vice versa.
You can add yield amounts as separate rows, but the tool does not track DeFi protocols, reward schedules, or compounding logic.
It provides a rough estimate. German tax rules include holding-period exemptions and specific cost basis requirements that this tool does not implement. Use it for orientation, then consult a tax advisor.
