The calculator will show you the exact change due and provide a breakdown of the bills and coins needed to make up that amount. This is particularly useful for cashiers to quickly determine the correct combination of bills and coins to return to the customer.

Formula Explained

The calculation of money change is straightforward. The formula used is:

Change Due = Amount Tendered - Amount Due

Where:

Amount Due is the total cost of the items or services being purchased.
Amount Tendered is the amount of money given by the customer to pay for the items or services.
Change Due is the amount of money that should be returned to the customer.

For example, if the amount due is $25.50 and the amount tendered is $30.00, the change due would be $4.50.

Worked Examples

Example 1: Simple Transaction

Suppose you are purchasing items that cost $15.75. You give the cashier $20.00. The change due is calculated as follows:

Change Due = $20.00 - $15.75 = $4.25

The cashier should return $4.25 to you, which can be given as one $2 bill, one $2 coin, and one $0.25 coin.

Example 2: Larger Transaction

If you buy a product that costs $56.80 and you pay with a $100 bill, the change due is:

Change Due = $100.00 - $56.80 = $43.20

The cashier should return $43.20, which can be given as two $20 bills, one $2 bill, one $1 coin, one $0.10 coin, and one $0.10 coin.
