What Is the Money Change Calculator?

The Money Change Calculator works out exactly how much change you should hand back after a cash transaction. Whether you run a market stall, a lemonade stand, or just want to double-check the cashier, this tool removes the mental math by subtracting what is owed from what was paid.

How to Use It

Enter two numbers: the Amount Paid (the cash the customer handed over) and the Amount Due (the total price of the items). Press calculate and the change to return appears instantly. If the result is negative, the customer still owes that much.

The Formula Explained

The math is simple subtraction:

$$\text{Change} = \text{Amount Paid} - \text{Amount Due}$$

For example, if a customer buys goods totalling $13.45 and pays with a $20 bill, the change is \(\$20.00 - \$13.45 = \$6.55\).

Change equals the amount paid minus the amount due.

Worked Example

A coffee costs $4.75. The customer pays with a $10 note. $$\text{Change} = \$10.00 - \$4.75 = \$5.25$$ You would return one $5 bill and one quarter.

The change broken down into the fewest coins and notes.

FAQ

What if the change is negative? A negative result means the amount paid was less than the price, so the customer still owes that amount.

Does it handle cents? Yes — enter dollars and cents (e.g. 13.45) and the result is shown to two decimal places.

Can I use it for any currency? Absolutely. The math is identical for any currency; just read the dollar sign as your local symbol.
