Why rates differ
A currency converter usually shows a reference rate from a data source. Banks, card networks, exchanges, and payment providers may apply spreads, fees, timing differences, or settlement rules. That is why the number you see online should be treated as an estimate unless the provider confirms a final rate.
When a converter is useful
- Planning a travel budget.
- Estimating an invoice in another currency.
- Checking whether a quoted amount is roughly reasonable.
- Comparing the direction of rate changes over time.
When to verify
Verify before sending money, booking a large purchase, preparing accounting entries, or making a tax-related decision. Use the official source for the transaction that will actually happen.
FAQ
Why does my bank show a different number?
Your bank may include a spread or fee and may use a rate from a different moment.
Are old cached rates safe to use?
They are fine for rough examples, but not for important decisions.
