About this tool
Splitting a bill seems simple until tax and tip enter the picture and someone's mental math is off. This calculator does it cleanly: enter the pre-tax subtotal, the tax rate, the tip percentage, and how many people are sharing, and it returns the tax, the tip, the grand total, and the exact per-person amount. It handles two details people often disagree about. First, whether to tip on the pre-tax subtotal (the etiquette norm, and what this defaults to) or on the post-tax total — a small but real difference. Second, an optional round-up that bumps each person's share to the next whole dollar, which over-collects slightly to cover rounding and leaves a touch extra for the server; the tool shows exactly how much extra that adds. All arithmetic is exact and runs in your browser, so there is no guessing and no awkward recalculation when the group size changes.
How to use it
- Enter the pre-tax bill subtotal.
- Set the tax rate and tip percentage (or tap a preset).
- Enter the number of people splitting.
- Read the per-person amount; toggle pre/post-tax tip or round-up as needed.
Frequently asked questions
- Should I tip on the pre-tax or post-tax amount?
- Etiquette guides generally say tip on the pre-tax subtotal, since the tax is not part of the service. Tipping on the post-tax total is also common and slightly more generous. The tool defaults to pre-tax but lets you switch.
- How is the per-person amount calculated?
- It adds tax and tip to the subtotal, then divides the grand total by the number of people. Tax = subtotal × tax%; tip = (pre- or post-tax base) × tip%; total ÷ people = each share.
- What does "round up per person" do?
- It rounds each person's share up to the next whole dollar, so everyone pays an even amount. That collects slightly more than the bill — the tool shows the small surplus, which conveniently pads the tip.
- Is 18–20% the right tip in the US?
- In US table-service restaurants, 18–20% of the pre-tax bill is customary for good service, with 15% on the lower end and 25%+ for exceptional service. Norms differ by country — many places include service or tip far less.
- Can it split unevenly by what each person ordered?
- This tool splits evenly. For an itemized split where each person pays for their own dishes plus a share of shared items, tax, and tip, use the itemized bill-split calculator.
- Is anything uploaded?
- No. All calculation runs in your browser with no network request.
