How this calculation works
Convert an amount using either your own exchange rate or the bundled ECB reference snapshot dated 2026-08-24. The rate is target-currency units for one source-currency unit. A positive manual rate replaces the snapshot; entering zero selects the snapshot. Neither mode includes a bank’s spread, transfer fee or card markup automatically.
Worked example
This example uses illustrative inputs. Your current result is shown above.
Choose USD as source and INR as target, enter 100 and a manual rate of 85 INR per USD. The result is 100 × 85 = ₹8,500 and the rate source is “Manual override”. The number 85 is an illustrative rate, not a current quote. Reversing the same assumed rate gives 1 ÷ 85 ≈ 0.0117647 USD per INR.
Assumptions and limits
- The bundled data is a static snapshot dated 2026-08-24, not a live feed. Its age matters for any real transaction.
- A manual rate must match the displayed direction: target currency per one source unit. Zero means use the reference snapshot, not a zero-value conversion.
- Fees, spreads, taxes, settlement timing and provider-specific rounding are excluded. ECB reference rates are information values rather than executable transaction quotes.
Questions people ask
Why is the answer different from my bank’s quote?
A bank can use a different market rate, spread, fee and settlement time. This tool multiplies by the displayed rate without those extra charges.
Does the exchange rate update when I open the page?
No. The bundled rate date stays visible, and the calculator makes no live exchange-rate request. Enter a current provider quote as a manual rate if that is the scenario you need.
How do I know which way round to enter a manual rate?
Read the rate label. If it says INR per USD, enter the rupees received for one dollar, not the dollars received for one rupee.
