Travel calculator

Currency Converter

Convert currencies with current reference rates, a selected historical date or a manual rate. Results include inverse rate, fee/spread impact and source freshness.

Rate mode

Reference rates are not transaction guarantees. Banks, cards and cash exchanges can add spreads, fixed fees and their own rate timing.

How the conversion is calculated

The core conversion is amount x exchange rate. In latest and historical modes, the rate is fetched through a server-side endpoint and cached. In manual mode, the rate is entered by the user.

Example

If 100 EUR converts at a 1.08 EUR/USD reference rate, the reference result is 108 USD. With a 2% spread and a fixed 1 USD fee, the amount received is lower than the reference result.

Historical rates

Historical mode is useful for invoices, accounting checks, old purchases and travel budgets. If the selected date is not available from the provider, the returned rate date is the authoritative date for the displayed result.

Fees and spreads

The reference result is not the same as a retail card, bank or cash exchange result. A 2% spread on a 100 EUR to USD conversion reduces the target amount by about 2% before any fixed fee entered in the calculator.

What to check before using the result

Reference exchange rates can change frequently and may not be available on weekends or holidays. The live provider can be unavailable, so the calculator includes manual fallback mode. Results are informational and not trading, accounting, tax or payment advice.
