Monster Currency Converter
Convert between 30+ world currencies at live mid-market rates — the date of the rates is printed right on the page, and if the live feed ever fails, a clearly dated backup table takes over instead of silently showing stale numbers.
Rate source: built-in backup table (November 2026). Converted figures update as you type.

How it works
Every rate is stored as "units per 1 US dollar", so converting A → B is amount ÷ rate(A) × rate(B) — the same mid-market method banks use before they add their markup. Rates are fetched live when the page opens from a public exchange-rate feed, and the page tells you exactly when they were updated. If the fetch fails (offline, blocked, feed down), the converter falls back to a built-in table and says so, with its date — you always know how fresh your rate is.
Formula & worked example
Formula: Converted amount = amount ÷ rate(your currency) × rate(target currency), where every rate is quoted against the US dollar, so any pair of currencies pivots through USD. Live rates load automatically when available; otherwise the tool uses built-in fallback rates dated November 2026.
Worked example: At the fallback rate of €0.92 per $1: $500 × 0.92 = €460.00. The inverse rate is 1 EUR = 1.08696 USD.
When to use this
- You are pricing a trip, a purchase or an invoice in another currency and need the real figure.
- A salary or freelance rate is quoted abroad and must be compared with a home-currency offer.
- You are checking a card or exchange bureau's rate against the mid-market rate.
- You are converting a historic amount for a report and need a stated-rate calculation.
How to use it, step by step
- Enter the amount.
- Pick the from and to currencies.
- Read the converted amount and the rate used.
- Use swap to reverse the pair — note the result is not exactly reciprocal at real-world spreads.
- For a purchase, compare your card's rate against the mid-market figure shown.
What the inputs mean
| Input | What it is | Typical values |

| From / to | The currency pair | 30+ major and common currencies |
| Rate | Units of target per 1 unit of source | Indicative mid-market rates |
Another worked example
At an indicative rate of 0.92 EUR per USD, $250 converts to €230.00, and €1,000 comes back as about $1,086.96. If a bureau offers you €215 for that same $250, the €15 gap — about 6.5% — is their margin, now visible because you knew the mid-market figure first.
Frequently asked questions
Are these exchange rates really live?
Yes — when the page loads it fetches today's rates from a public feed and prints the update time above the converter. If that fetch fails for any reason, a built-in backup table (dated November 2026) is used instead and the page labels it clearly, so stale rates are never passed off as live.
Why does my bank give me a different rate?
Banks and transfer services add a markup (typically 1–5%) plus fees on top of the mid-market rate shown here. This converter shows the mid-market benchmark so you can see exactly how much a service is charging you.
What is the swap button for?
It exchanges the From and To currencies in one tap, so you can check the reverse conversion — handy when a price is quoted in the foreign currency and your budget is in dollars.
Which currencies are supported?
More than 30 majors and widely used currencies: USD, EUR, GBP, JPY, AUD, CAD, CHF, CNY, INR, MXN, BRL, KRW, and many more. The live feed supports additional currencies beyond the backup table.
💸 Borrowing in any currency?
The Loan Calculator solves for payment, amount, term or rate — and shows what extra payments save you.
Why does my bank give me a different number?
Banks and bureaus quote the mid-market rate minus a margin (typically 1–6% for cards and far more at airport desks), sometimes plus a fee. This converter shows the mid-market calculation so you can measure exactly what any provider's margin costs you.
Are these live rates?
The rates are periodically updated indicative figures, not a trading feed — fine for budgeting and comparison, not for settling an invoice to the cent. For a large transfer, the provider's confirmed quote at the moment of sending is the binding number.
