Tip amount: 12.68Personal inputs stay on this device. Sharing sends the calculator page without these values.
Rounding the tip and rounding the total are not the same thing. On an 84.50 bill at fifteen percent, rounding the tip gives 13.00 and rounding the total gives 13.50 — the second is the one people usually mean when they say they rounded up.

tip = selected base × percent / 100; final payment = bill + rounded tip; split whole cents
The bill is the amount payable before the tip, including any tax already charged. Enter that included tax separately only to choose a pre-tax tip base; it is never added to the payment again. First calculate the tip using the selected base and percentage, then apply the chosen aggregate rounding.
With no whole-unit rounding, the tip is rounded half up to cents for payment. Add that tip to the bill and distribute the resulting whole cents between the selected number of people. If the total does not divide equally, the stated number of people pays one cent more. The displayed counts and amounts always add up to the final payment; the primary tip calculation keeps its original precision for reverse calculations.
Rounding the tip raises the tip itself to the next whole unit. Rounding the total raises bill plus tip and leaves the tip whatever remains — 13.00 against 13.50 on an 84.50 bill at 15 %.
Enter the amount payable before tip, including any tax. For a pre-tax tip base, enter that already-included tax separately and select bill minus tax. Tax is never added to the payment twice.
The table above only shows what is usual where; the page does not decide it. The percentage is yours to set.
MisconceptionI said round up, so the tip goes to the next whole unit.
CorrectionThat is one of the two options. Rounding the total up is what most people mean, and on 84.50 at 15 % it gives 13.50 rather than 13.00.
MisconceptionRounding the total up always adds only small change to the tip.
CorrectionIt adds whatever lifts bill plus tip to the next whole unit. On 67.30 at 20 % the tip goes from 13.46 to 13.70.
MisconceptionThe calculator knows whether my bill includes tax.
CorrectionEnter any tax already included separately and choose the tip base. The payable bill itself remains unchanged.
| Where | Customary in the US |
|---|---|
| Sit-down restaurant | 15–20 % of the bill before tax |
| Counter service | Optional, often nothing |
| Taxi or rideshare | 10–15 % |
| Hotel housekeeping | A few dollars per night |
Rounding the tip raises the tip itself to the next whole unit; rounding the total raises the bill plus tip. On 84.50 at 15 % that is 13.00 against 13.50 — the second is what most people mean by rounding up.
The bill field is the payable amount including tax, before tip. Enter the included tax separately and choose bill minus tax for a pre-tax tip base, or use the full bill. This never adds the tax again.
It depends on the country and the service; the table above shows what is customary. The calculator assumes no rate of its own — the percentage is yours to set.
Yes, the percentage field starts at 0. Rounding the tip up leaves it at zero, but rounding the total up does not: a bill of 84.50 still rounds to 85 and leaves 50 cents behind. Only on a whole-number bill does every setting give exactly zero.
