💱 Overview: Currency Converter Using Custom Exchange Rate
This Simple Currency Converter allows you to convert any amount between two currencies using your own specified exchange rate. It's ideal for travel, budgeting, or any situation where you have a personal or fixed rate — such as one offered by your bank, exchange office, or remittance provider.
Unlike most converters, this tool is:
- 🛜 Offline-friendly — no internet connection needed
- 🔐 Private — no data sent or stored anywhere
- 📈 Customizable — works with any rate you choose
Just input your base amount, select the currency symbol (optional), and enter your desired exchange rate.
📐 Formula Used
This tool follows a very simple but essential formula:
Converted Amount = Input Amount × Exchange Rate
For example, converting 100 Euros at a rate of 1.10 to USD gives:
100 × 1.10 = 110 → You get $110
This allows you to compare manual conversion against live rates or calculate expected totals for specific rate agreements.
🧭 Use Cases & Benefits
This converter is perfect for:
- 🌍 Travelers using local or cash desk exchange rates
- 💸 Remittance senders checking bank-offered conversion rates
- 💼 Freelancers billing clients in foreign currencies
- 📊 Budget planners comparing different FX offers
- 🛒 Shoppers comparing foreign prices vs. local rates
- 🧾 Bookkeeping where a fixed exchange rate is pre-defined
You can also scale results by changing the rate multiple times — ideal for comparing real market rates with card or ATM exchange values.
🧮 Examples
-

Where should I get an exchange rate?
You can use the rate from your bank, credit card statement, currency kiosk, ATM receipt, or forex platform. Rates vary slightly depending on service fees or spreads.
Does this tool update rates automatically?

Yes. This converter runs entirely in your browser and does not require any data connection.
Is the tool suitable for cryptocurrencies?
Yes, if you know the current crypto-to-fiat rate (e.g., BTC to USD). Just input the amount and rate as you would for fiat currencies.
Can I copy or export my result?
Yes. Use the “Copy Results” button to save or share your conversion, or print/export for record-keeping.
How accurate is the result?
The tool provides mathematically exact results based on your entered rate — but it’s only as accurate as the rate you provide.
