How the Localized Price Rounding Calculator works
Rounding a converted price down to a tidy local number is a small, permanent, one-directional margin leak. Customers never saw the converted price, so rounding up to the nearest charm point is usually free.

Frequently asked questions
Should I round converted prices?
Always — a price of 47.83 looks like a conversion and reads as unconsidered. What matters is which direction you round.
Which way should I round?
Up, in most cases. The customer has no reference point for the converted figure, so rounding up costs nothing in perception and adds margin on every unit.
Do charm prices work in every market?
The .99 convention is widespread but not universal — some markets prefer round numbers, and in others certain digits carry associations. Local convention beats the home-market habit.
How much does rounding cost?
Whatever the difference is, times every unit sold. It is small per unit and permanent, which is exactly the kind of leak that never gets found.
