Calculate your restaurant tip, total bill, and effective tip percentage in the US. Choose pre‑tax or post‑tax base, rounding, and split the bill easily.
Last updated: 19 October 2026
Use this restaurant tip calculator (and delivery, salon, or any bill) to find the tip amount and the total with tip from your bill, tax, and tip percentage. You choose the tip percentage, the base (pre-tax or post-tax), rounding, and how many people split the total.
What this tool does not do: it does not set a required tip percentage, does not calculate tip payroll taxes for workers, and does not handle itemized per-item bill splitting. Tipping percentages are social customs, not laws.
Extra tip is $0.00 because a service charge is marked as already included.
Limitation: the tip percentage is a user-chosen convention, not a legal rule. This page does not compute tip income tax or wage rules for workers.

Tip = tip % × base, where base is the pre-tax bill (default) or bill + tax. Total = bill + tax + tip. Effective tip % = (total − bill − tax) ÷ bill × 100 after rounding. Tip is rounded half up to the cent.
No US federal or state rule sets a required customer tip percentage (calculator convention). Optional reference starting points the reader may check: U.S. DOL Wage and Hour DivisionFigures you enter drive the result.
Privacy: the calculation runs in your browser. Bill and tip values are not sent to a server.
Should you tip on tax? Many people choose the pre-tax subtotal; others use the full receipt total. The table below always shows both bases with the same tip percentage so the dollar difference is clear.
| Tip base | Base amount | Tip at your percentage | Total with tip | Difference vs pre-tax tip |
|---|---|---|---|---|
| Pre-tax bill | $86.40 | $17.28 | $110.81 | — |
| Bill plus tax | $93.53 | $18.71 | $112.24 | +$1.43 |
When tax is zero, both rows match. Change the tax field above to update this table.
These rows are computed from your bill amount for convenience. They are selectable examples only, not recommendations of a standard rate. Gratuity is another word people use for tip; this gratuity calculator treats the two the same way.
| 20% tip calculator row | Tip amount | Total with tip (bill + tax + tip) |
|---|---|---|
| 15% | $12.96 | $106.49 |
| 18% | $15.55 | $109.08 |
| 20% | $17.28 | $110.81 |
| 25% | $21.60 | $115.13 |

Every symbol is defined below. Arithmetic uses exact decimal steps; the tip is rounded half up to the cent; the effective percentage is shown to two decimal places. Use the round up tip calculator options (round total up or round tip up) when you prefer a whole-dollar figure; the effective percentage beside the result shows the real rate after that change.
Rounding the total up to the next dollar changes the tip, and the page shows the resulting effective percentage next to the result. Rounding the tip up to the next dollar works the same way.
Move the decimal one place left to get 10 percent, then double it for 20 percent. On a hypothetical $50.00 pre-tax bill: 10% is $5.00, so 20% is $10.00. For 15%, take 10% plus half of 10%. For 25%, double 10% then add another 2.5% (half of 5%).
These examples use clearly labelled hypothetical inputs to show the substitution step by step. They test arithmetic only, not law or local custom.
Inputs (hypothetical): bill $86.40, tax $7.13, tip percentage 20%, base = pre-tax.
Substitution: Tip = 20 ÷ 100 × 86.40 = 17.28. Total = 86.40 + 7.13 + 17.28 = 110.81. Effective tip % = 17.28 ÷ 86.40 × 100 = 20.00%.
Result: tip $17.28, total with tip $110.81.
Inputs (hypothetical): bill $86.40, tax $7.13, tip percentage 20%, base = bill plus tax.
Substitution: Base = 86.40 + 7.13 = 93.53. Tip = 20 ÷ 100 × 93.53 = 18.706 → 18.71 (half up to the cent). Total = 86.40 + 7.13 + 18.71 = 112.24. Difference from the pre-tax tip = 18.71 − 17.28 = 1.43.
Result: tip $18.71, total with tip $112.24, $1.43 more tip than Example A.
Inputs (hypothetical): same as Example A with rounding = round total up.
Substitution: Unrounded total = 110.81. Rounded total = 111.00. Tip becomes 111.00 − 86.40 − 7.13 = 17.47. Effective tip % = 17.47 ÷ 86.40 × 100 ≈ 20.22%.
Result: tip $17.47, total $111.00, effective tip 20.22% — not exactly 20% any more.
Inputs (hypothetical): Example A with rounding = round tip up, people = 3.
Substitution: Unrounded tip = 17.28 → rounded tip up = 18.00. Total = 86.40 + 7.13 + 18.00 = 111.53. Effective tip % = 18.00 ÷ 86.40 × 100 ≈ 20.83%. Per person on the rounded-total variant of $111.00 among 3 people: 37.00 each (exact).
Result: tip $18.00, total $111.53, effective tip 20.83%.
Two comparison tables help you see which choices move the number most.
| Rounding option | Tip | Total | Effective tip % of pre-tax bill |
|---|---|---|---|
| None (nearest cent) | $17.28 | $110.81 | 20.00% |
| Round total up to the next dollar | $17.47 | $111.00 | 20.22% |
| Round tip up to the next dollar | $18.00 | $111.53 | 20.83% |
| Percentage | Tip amount | How to get it mentally |
|---|---|---|
| 15% | $7.50 | 10% ($5.00) plus half of 10% ($2.50) |
| 18% | $9.00 | 10% ($5.00) plus 8% (double 4% ≈ $2.00 + $2.00) |
| 20% | $10.00 | Double the 10% amount |
| 25% | $12.50 | Double 10% ($10.00) plus 2.5% ($1.25) plus another 1.25% |
The tip calculator split feature divides the total evenly among up to 50 people. Cents are allocated by largest remainder so the parts add up exactly; ties go to the lowest person number. For itemized splits (different items for different people), use a dedicated bill-split tool — that feature is outside this page’s scope.
Example: $111.00 among 3 people is $37.00 each (exact).
No US federal or state rule sets a required tip percentage for customers. Tipping is a social custom; the percentage is your choice. This page does not label any percentage as standard or required. Enter the tip percentage you intend to leave and the tool shows the tip amount and total with tip.
You can tip on the pre-tax bill or on the bill plus tax. This calculator defaults to the pre-tax base and shows post-tax results side by side with the dollar difference so you can see how the base changes the tip. There is no legal requirement modeled here either way.
Take 10 percent by moving the decimal one place left, then double that number. On a $50.00 bill, 10 percent is $5.00 and 20 percent is $10.00. The quick-reference table above repeats this check for other common percentages on the bill you entered.
In everyday US usage, gratuity and tip both mean a voluntary extra payment to service staff. Some receipts print an automatic gratuity or service charge; that line is already part of the bill. If you mark service charge included, this tool sets the extra tip to $0.00 so you are not led into double tipping.
No. The preset buttons are selectable values only. Customs vary by place, party size, and type of service, and they are not modeled as rules on this page. Choose the tip percentage that fits your situation.
Set the number of people (1 to 50) and the per-person figure shows the exact share of the total, allocated in whole cents. For itemized splitting by dish or seat, you need a bill-split tool; that is outside this calculator scope.
If you are budgeting the whole outing or month, Varnda also offers a paycheck calculator to estimate take-home pay, a credit card payoff calculator for time-to-pay planning, a personal loan calculator for monthly payment and interest, and a mortgage calculator with taxes, insurance, and PMI. Itemized bill splitting is a separate task from this tip and total calculator.
This tip percentage calculator shows the tip amount, total with tip, effective tip percentage after rounding, and the per-person share from the bill you enter. Adjust the tip base, rounding, and people count above; the result updates in your browser without sending your numbers anywhere.
