Split Bill Calculator
A total bill, a group size, and a combined tax-and-tip percentage — this collapses straight to what each person actually owes, including all the extras baked into one number.

1,120 each
Grand total 5,600
How the split bill calculator works
Grand total = bill × (1 + tax & tip percentage ÷ 100).
Each person's share = grand total ÷ number of people.
Worked example: 5,000 bill, 5 people, 12% tax & tip
- Grand total = 5,000 × 1.12 = 5,600.
- Each person = 5,600 ÷ 5 = 1,120.
Common mistakes to avoid
Entering tax and tip as two separate additions on top of this tool's single percentage
This calculator expects one combined percentage covering both tax and tip together — if you enter only the tax rate and plan to add tip mentally afterward, the per-person figure won't reflect the true final total.
Assuming an even split is always fair
This tool assumes everyone owes an identical share — for a group where people ordered very different amounts, an even split can noticeably overcharge light eaters and undercharge heavy ones.
Frequently asked questions
How do I combine tax and tip into one percentage if I know them separately?
Add them directly if both apply to the same base amount — an 8% tax plus a 15% tip both calculated on the bill total combine to 23% for this calculator's single field.
What if some people already paid for part of the bill, like drinks separately?
Subtract any amounts already covered separately from the total bill before entering it here, so the remaining group split reflects only the shared portion.
Is this the same as splitting a restaurant bill using an app?
The underlying math is identical — this just does the calculation directly without needing to install anything for a quick, one-off split.
Does rounding matter much for large groups?
For larger groups, small rounding differences per person can add up to a noticeable gap between the sum collected and the actual total owed — round up slightly, or have one person cover any small shortfall.
