Frequently asked questions

Which bills and coins does it use?

It defaults to US denominations: $100, $50, $20, $10, $5, $1, and quarters, dimes, nickels and pennies.

Does it always give the fewest pieces?

Yes. It uses a greedy method from the largest denomination down, which is optimal for standard US currency.

Is it accurate with cents?

Yes. All math runs in whole cents internally, so there is no floating point rounding error.

Can I use it for a cash drawer or till?

Absolutely. It is built for counting drawers and making change, and the total piece count helps you confirm the count.

Is my data private?

Yes. Everything is calculated in your browser and nothing is uploaded.
