How does rounding work?

Choose 1, 10, 100, or 1000 to round the standard share to that unit. The last person absorbs the difference so the total stays exact.

Why is the last person amount different?

The last person absorbs the rounding difference so the final total remains exact.

Can I include card fees, tax, delivery, or tips?

Yes. Enter the final paid total after any fees or tips that should be shared.

Can the last person become negative?

It can happen if the rounding unit is too large for the total and group size. The tool now warns you and suggests a smaller unit or rounding down.

Settlement examples

If the total is 48,000 and 5 people split it, the exact per-person amount is 9,600. With 100-unit rounding, 4 people pay 9,600 and the last person also pays 9,600, so the total matches without adjustment.

If the total is 50,000 and 3 people split it with 100-unit rounding, 2 people pay 16,700 and the last person pays 16,600. The final collected amount still equals 50,000.

Input guidelines

Use a whole-number total from 1 to 1 trillion.
Use 1 to 200 people.
If the last-person amount would become negative, lower the rounding unit or choose round down.
Include tax, delivery fees, tips, or service charges in the total if they should be shared.

FAQ

When should I use the rounding unit?

Use it when exact small units make transfers awkward and you want cleaner 10, 100, or 1000-unit payment amounts.

Why is only the last person different?

The last person corrects the rounding difference so the collected total equals the original bill.

Can I use it on mobile?

Yes. It runs in the browser and keeps the calculation on your device.

What happens with one person?
