About Change Due Calculator

Change is simply tendered minus the amount due, but where the smallest coin has been withdrawn the total must be rounded to the nearest available denomination. Several countries have removed one and two cent coins and round cash payments to the nearest five.

Formula

Change

change = tendered - total, rounded to the nearest available coin

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
