How Currency Conversion Rates Work
A rate quote is a ratio: EUR/USD 1.0850 means 1 euro buys 1.0850 dollars — the first currency is always 1 unit. Inverting gives USD→EUR = 1 ÷ 1.0850 = 0.9217. Misreading direction is the most common conversion error.
You never get the mid-market rate you see on Google: banks and cards add 1-3% spread, and dynamic currency conversion (paying in your home currency abroad) adds another 3-6%. The calculator's fee field shows the real amount you'll get.
Worked Example: €2,000 → USD with card fees
Mid-market: 2,000 × 1.0850 = $2,170.00
Card FX fee 2%: 2,170 × 0.98 = $2,126.60
Paying in USD at a European terminal (DCC 5%): 2,170 × 0.95 = $2,061.50
Best practice (pay in EUR, no DCC): saves ~$65 vs the worst option
Rate choice moves money more than rate movement on short trips: the spread you accept costs more than a week's volatility.
Frequently Asked Questions
Why do rates change constantly?
FX is a 24/5 auction: rates move with interest-rate differentials, inflation prints, trade balances, and risk sentiment. Trillions change hands daily, so even small news shifts prices within seconds — weekend rates are just Friday's close.
What is the mid-market rate?
The midpoint between what buyers bid and sellers ask — the 'real' rate with no margin. Google, xe.com, and our calculator default to it. It exists only as a reference; every actual transaction embeds a spread.
Should I pay in local currency or my home currency abroad?
Always local. The terminal's 'pay in your currency' (DCC) uses a privately-set rate 3-6% worse than your card's network rate. Let YOUR bank do the conversion — and pick a no-FX-fee card to get near-mid-market.
How do pegged or managed currencies work?
Some currencies (HKD to USD within a band, SAR, AED) are defended by their central banks, so rates barely move. Others are managed floats with gradual crawl. Pegs can break (CHF 2015 jumped 20% in minutes) — pegged ≠ risk-free.
