A fixed rate locks the amount you will receive at the moment you create the order — safe from market moves but usually with a slightly larger margin. A floating rate follows the market until your deposit confirms — often a little cheaper, but the final amount can change.
Fixed rate
With a fixed rate, the exchanger guarantees the output amount for a short window. If the market swings while your transaction confirms, you are protected. The service prices that protection in, so the quoted rate is a touch less generous. Best when you want certainty or the market is volatile.
Floating rate
With a floating rate, the final amount is calculated when your deposit arrives and confirms. If the market moves in your favor you get more; if it moves against you, you get less. It is often marginally cheaper because there is no protection premium. Best for calm markets and when you are comfortable with small variation.
| Fixed | Floating | |
|---|---|---|
| Output amount | Locked | Can change |
| Typical cost | Slightly higher | Slightly lower |
| Best when | Volatile market, need certainty | Calm market, want the best price |
Which to choose
- Big order or nervous market → fixed.
- Small order, calm market, chasing the best price → floating.
- Either way, compare offers first on an aggregator so the base rate is competitive.
FAQ
Does floating always cost less?
Not always. It usually starts cheaper, but if the market moves against you before confirmation, the final amount can end up lower than a fixed quote.
Why is a fixed rate more expensive?
The exchanger absorbs market risk for you and prices that guarantee into the rate.
Can the rate change after I send funds on a fixed order?
Within the guaranteed window, no. If you miss the window, the service may re-quote.
