Cash Change Calculator
Subtracts the total from the cash tendered and lays out the change using the fewest US bills and coins, so you can count it back with confidence.
- $5 bill×1
- quarters×2
- dime×1
- pennies×3
How it works
The change owed is simply the cash handed over minus the amount due. Hand over $20 on a $14.37 bill and you're owed $5.63. The calculator does that subtraction and, if the cash falls short, tells you how much more is needed instead of showing a nonsense negative.
Then it counts that change the way a good cashier would: biggest denominations first, working down. $5.63 becomes a $5 bill, two quarters, a dime, and three pennies — the fewest pieces of money that add up exactly. No hunting for the right combination in your head.
It runs on standard US denominations from the hundred-dollar bill down to the penny. That makes it a quick helper for a market stall, a cash register, teaching kids to make change, or just double-checking that a cashier handed you back the right amount.
Frequently asked questions
How is the change broken down?
It uses the greedy method — largest denomination that fits, then the next, all the way down to pennies. For US currency this always gives the fewest total bills and coins, which is exactly how change is normally counted back.
What if the cash isn't enough to cover the bill?
The calculator won't invent negative change. Instead it tells you the amount still owed, so you know how much more cash is needed to complete the purchase.
Which denominations does it use?
Standard US money: $100, $50, $20, $10, $5, and $1 bills, plus quarters, dimes, nickels, and pennies. Half dollars and dollar coins are rare in day-to-day change, so it sticks to the common set.
