Tip Calculator
Work out the tip and total for any bill, split it between people, round the total up, and tip on the pre-tax amount — with a 15–25% comparison table.
Tip Calculator: with the default inputs, tip is $11.52.
The total on the check.
15% is the US floor for table service; 18–20% is standard.
- Total with tip
- $75.52
- Each person pays
- $75.52
- Tip per person
- $11.52
- Effective tip rate
- 18%Tip as a share of the full bill — differs from the slider when rounding or tipping pre-tax.
Assumptions
- The tip percentage applies to the whole bill unless you enable pre-tax tipping.
- Rounding up increases the tip so the grand total lands on a whole dollar.
- Splits are even; use the split bill calculator for uneven shares.
| Tip % | Tip | Total | You pay |
|---|---|---|---|
| 15% | $9.60 | $73.60 | $73.60 |
| 18% | $11.52 | $75.52 | $75.52 |
| 20% | $12.80 | $76.80 | $76.80 |
| 22% | $14.08 | $78.08 | $78.08 |
| 25% | $16.00 | $80.00 | $80.00 |
How this is worked out
The formula
tip = bill × tip% ÷ 100 total = bill + tip per person = total ÷ people Pre-tax option: tip = (bill − sales tax) × tip% ÷ 100 Round-up option: total = ⌈bill + tip⌉, tip = total − bill

About this calculator
Type the bill and a tip percentage and you get the tip, the total, and what each person owes if you're splitting. The table underneath shows 15%, 18%, 20%, 22% and 25% side by side so you can pick without re-typing.
How to use it
- Drag the slider or type a percentage. In the US, 15% is the floor for sit-down service and 18–20% is the norm; 20%+ for excellent service, large groups, or when the kitchen bent the rules for you.
- Set Split between to divide the total and the tip evenly.
- Open More options to round the total up to a whole dollar (the tip absorbs the difference — handy when you're writing the total on a receipt) or to tip on the pre-tax amount. If you choose pre-tax, enter the sales-tax line from the check; the tip is calculated on the food and drink only.
Reading the results
Tip is the headline number. Total with tip is what you write on the receipt. Effective tip rate tells you what percentage of the full bill you actually left after rounding or pre-tax adjustments — useful if you want to make sure a pre-tax 18% still lands at a respectable number.
Pre-tax or post-tax?
Etiquette guides (Emily Post included) say tipping on the pre-tax amount is acceptable, and most restaurant POS terminals compute their suggested tips on the post-tax total. The difference on a $64 bill with 8% tax is about $0.92 at 18%. Servers, understandably, prefer post-tax. Do what you like; the calculator handles both.
Quick mental math
Ten percent is the bill with the decimal moved one place left. Double it for 20%. For 15%, take 10% and add half of that again. For 18%, take 20% and knock off a tenth of it. If the bill is $64: 10% = $6.40, 20% = $12.80, 15% = $9.60, 18% ≈ $11.52.
Edge cases
Counter service, takeout, and delivery run on different norms — 10% or a flat few dollars is common for takeout, and delivery tips should reflect distance and weather rather than the bill size. If a "service charge" or "gratuity included" line already appears (common for parties of six or more), that's the tip; anything extra is optional.
Frequently asked questions
▸How much should I tip at a restaurant?
In the US, 15% is the minimum for table service and 18–20% is standard. Tip 20% or more for great service or large groups. In many other countries 5–10% or rounding up is the norm, and in Japan tipping is not customary.
▸How do I calculate an 18% tip?
Multiply the bill by 0.18. On $64 that's $11.52. Mentally: take 20% ($12.80) and subtract a tenth of that ($1.28).
▸Should I tip on the total before or after tax?
Either is acceptable. Tipping on the pre-tax amount is technically correct by most etiquette guides; tipping on the after-tax total is more generous and is what most card terminals suggest. The difference is usually under a dollar.
▸Do I tip on a bill that already includes gratuity?
No. An automatic service charge or 'gratuity included' line — common for parties of six or more — is the tip. You can add a little extra for outstanding service, but it isn't expected.
▸How do I split a bill unevenly?
Use the split bill calculator, which lets one person carry a different share. This calculator splits the total evenly.
