Spot exchange rate.
In plain English
The spot exchange rate is the price at which one currency can be exchanged for another right now, for near-immediate delivery. It is the number quoted on financial sites and the reference point most other currency prices are built from. Banks, card networks, and exchange counters add a markup on top of the spot rate when they serve retail customers, so the rate you actually receive is not the raw spot rate. Spot rates move continuously, because the currency market trades around the clock on weekdays.
01Why it matters
The gap between the spot rate you looked up and the rate your card or exchange counter gave you is the real fee, and it is often larger than any line item actually labeled fee.
02The math, step by step
Say spot is 1.10 dollars per euro and an airport counter offers 1.19. On a 500 euro exchange, spot would cost 550 dollars and the counter charges 595. That 45 dollar difference is about 8 percent, collected without the word fee appearing anywhere.
Illustrative example. The amounts here are hypothetical, chosen to show how the math works, not real quoted rates or figures.
03What this is NOT
The spot rate is not what you were charged. Your bank or card network applies its own rate, plus any foreign transaction fee. Comparing the two on the same day is how you find the real cost of a conversion.
