Price conversion rounding calculator.

Rounding a converted price

A straight conversion rarely lands on a price you would publish: 24.99 at a rate of 0.92 is 22.9908. This table applies the rounding rules shops commonly use to that figure: nearest 0.05, 0.10 or 0.50, whole units, tens, a .99 / .95 / .90 ending, and always up or always down. Each row shows the resulting price and its percentage change from the converted amount, so you can see what a tidy price costs or earns you.

Endings and direction

"Ending .99 (nearest)" picks the closest price of the form N.99, which may be below or above the converted amount; "round up" always moves to the next N.99 at or above it. For zero-decimal currencies such as JPY, KRW and ISK the tool uses whole-unit endings (for example 1,980) instead of cents, since ISO 4217 gives those currencies no minor unit (SIX, ISO 4217 currency codes and minor units, List One checked October 2026). Halfway cases go to the lower price.

The percentage change is arithmetic only; the tool does not claim any ending improves conversion. For a full price list across currencies use the multi-currency price list builder.

Frequently asked questions

How do I round a converted price?

Multiply by your exchange rate (and buffer), then pick a rule: a step such as nearest 0.05 or 1, or an ending such as .99. The table shows each result and its percentage difference from the unrounded figure.

Should I round up or down after converting?

Rounding up protects margin against rate movement; rounding down is more generous to the buyer. The change column shows the size of either choice so you can decide.

How are zero-decimal currencies handled?

Currencies such as JPY, KRW and ISK have no minor unit in ISO 4217, so the tool shows whole-unit steps and endings like 80 or 98 instead of cents.

Where does the exchange rate come from?

You type it. No rate is fetched, so use your bank, processor or central-bank rate for the date you price.
