What percent should you tip?
Twenty percent is a good tip at a sit-down restaurant, 18% is standard, and 15% is now low for table service. Salons, barbers, and rideshare take 15 to 20%, and delivery adds a $4 to $5 minimum on small orders. The calculator tests any percentage on your bill, so you can compare rates before you pay.
The formula guide shows the simple math behind every percentage, with worked examples at 15%, 18%, and 20%. The mental math guide teaches three tricks for finding a tip in your head when your phone stays in your pocket.
Gratuity is another word for a tip. A gratuity calculator and a tip percentage calculator do the same job: they turn a bill total and a percentage into a dollar amount.
How do you find 20% of any bill?
Move the decimal point one place left to find 10%, then double it. On a $60 check, 10% is $6, so 20% is $12. On an $85 check, 10% is $8.50, so 20% is $17. The trick works on any bill with no phone. Use the calculator above when you want the exact total and split too.
How do you use the tip percentage calculator?
Enter the bill total, tap a percentage or type your own, and set the number of people if you are splitting. The calculator shows the tip amount, the grand total, and each person's share at once. Try each rate on the same bill to see the dollar gap between 15%, 18%, and 20% before you pay.

How much is the tip at each percentage?
On a $100 bill, the tip is $15 at 15%, $18 at 18%, $20 at 20%, and $25 at 25%. The table shows all four rates on bills from $20 to $200. All tips are figured on the bill total you enter. Find your bill amount in the left column and read across to compare rates.
| Bill total | 15% tip | 18% tip | 20% tip | 25% tip |
|---|---|---|---|---|
| $20.00 | $3.00 | $3.60 | $4.00 | $5.00 |
| $40.00 | $6.00 | $7.20 | $8.00 | $10.00 |
| $60.00 | $9.00 | $10.80 | $12.00 | $15.00 |
| $80.00 | $12.00 | $14.40 | $16.00 | $20.00 |
| $100.00 | $15.00 | $18.00 | $20.00 | $25.00 |

What does the math look like on a $75 bill?
A $75 bill with a 20% tip needs a $15 tip, so the total is $90. At 18%, the tip is $13.50 and the total is $88.50. At 15%, the tip is $11.25 and the total is $86.25. The steps below show the same math the calculator runs, so you can check each number before you pay.
The formula is simple
Tip Amount = Bill Amount × Tip Percentage
Total Bill = Bill Amount + Tip Amount
For example: $75 × 0.20 = $15 tip. $75 + $15 = $90 total. Split four ways: $90 / 4 = $22.50 each.
The gap between 15% and 20% on $75 is $3.75. Small on one bill, but it adds up for the person serving you across a full shift. When the service was good, the higher rate is the fair choice.
To find 10% in your head, move the decimal one place left: 10% of $75 is $7.50. Double it for 20% ($15) or add half for 15% ($11.25). The mental math guide shows how the same tricks work on any check.
The rates
What tip percentage should you use?
Use 20% for good service, 18% for standard service, and 15% as the floor. The same three rates cover restaurants, salons, rides, and delivery, because the custom is one custom: a percentage of the pre-tax price, picked by how good the service was. The calculator applies any percentage you enter, including rates outside the three standards.
15%
The floor
Adequate service, nothing more. On a $75 bill, 15% is $11.25.
20%
The standard
Good service anywhere: table, chair, car, or door. On a $75 bill, 20% is $15.
25%
Generous
Service that went beyond the basics. On a $75 bill, 25% is $18.75.
The percentage is a share of the price before tax. A 20% tip on a $75 meal is $15, whether the meal was dinner, a haircut, or a ride across town. The service changes, the math does not. When the price includes a service charge or an automatic gratuity, subtract that amount from the tip you planned, so the total tip stays at the rate you picked.
What changes it
What changes the percentage you pick?
Service quality, the setting, the size of the bill, and whether a service charge is already included all change the percentage. Small bills and big bills follow the same rates, but small bills need a dollar floor, and big bills reward rounding to a clean total.
Service quality
The main lever. Good service earns 20%, standard service earns 18%, and adequate service earns the 15% floor.
Setting
Table service tips 20%. Counter service tips 0% to 10%. Bar drinks tip $1 to $2 each, or 15% to 20% of the tab.
Bill size
Small bills need a dollar floor: 20% of a $12 lunch is $2.40, which is too little for a delivery. Large bills follow the same rates and round to a clean total.
Service charges
Subtract a printed service charge or automatic gratuity from the tip you planned. The total tip should land at the rate you picked, not above it.
Rounding
Round the total to a clean dollar when the cents are ugly. The calculator's rounding modes do this on the total or per person.
Currency
The percentage works in any currency. The calculator covers dollars, euros, pounds, rupees, and yen at the same rates.
The data
What percentage do most people actually tip?
Pew Research Center surveyed 11,945 US adults in 2023 and found that 57% tip 15% or less for an average sit-down meal, while 25% tip 20% or more. Payment data runs higher: Toast reported an average full-service tip of 19.1% in the second quarter of 2026, because card tips skew toward the suggested presets.
57%
Of US adults tip 15% or less for an average sit-down meal, per Pew Research Center (2023).
19.1%
Average full-service tip in Q2 2026, per Toast platform data. Card and digital tips only; cash is excluded.
The gap between the two numbers is the gap between what people say and what the card machine records. Surveys catch every meal, including the ones where no tip was left. Card data catches only the meals where a tip was added by card, and the preset screens push those tips up. The honest read: 20% is the standard people aim for, most land near it, and the average card tip sits just under it.
Pew also found that 72% of adults say tipping is expected in more places than five years ago. The percentage you pick is a habit, not a negotiation. Fix your three rates, 15%, 18%, and 20%, and use them everywhere. The calculator remembers nothing and judges nothing. It just does the math.
Tricky situations
What trips people up with tip percentages?
Four situations cause most of the confusion with percentages: tipping on the after-tax total, the preset screen, discounted prices, and splitting the percentage across a group. Each has a simple answer, and the rule behind all four is the base: figure the percentage on the pre-tax, full price, then split the total.
Tipping on the after-tax total
The custom is pre-tax. The difference is small, often a dollar or two, and either way is fine in practice. Pre-tax is the rule, and the calculator uses the amount you enter, so enter the subtotal.
The preset screen
Presets of 25%, 30%, and 35% are suggestions set by the house. The custom amount option always exists, and 20% entered by hand is always allowed.
Percentages on discounted prices
Tip on the full price. A discount changes what you pay, not what the service was worth, and the percentage follows the service.
Splitting the percentage
The percentage applies to the whole check. Figure the tip on the full total, then split the total. Splitting first and tipping each share separately invites rounding errors.
Worked example
How do you find 20% in your head?
Move the decimal one place left to find 10%, then double it. On a $75 check, 10% is $7.50, so 20% is $15.00. For 15%, take the 10% number and add half of it: $7.50 plus $3.75 is $11.25. Three moves, no calculator, and the answer is exact.
The math, step by step
10% of $75 = $7.50 (move the decimal)
20% = $7.50 × 2 = $15.00
15% = $7.50 + $3.75 = $11.25
25% = $15.00 + $3.75 = $18.75
On a $64 check, 10% is $6.40, 20% is $12.80, and 15% is $9.60. The trick works on any amount, including odd totals, because moving a decimal never needs rounding. When the bill is large or the group is splitting, the calculator is still faster, and it shows every share.
What else do people ask about tip percentages?
Tip percentage questions usually cover the right rate, the mental math tricks, and the dollar amounts on real bills. The answers below give the standard rates with worked examples you can check. For service-by-service rates, the calculators on the hub page cover restaurants, salons, delivery, and rideshare on their own.
What percent is a good tip?
Twenty percent is a good tip at a sit-down restaurant in the US. Eighteen percent is standard, and 15% is now low for table service. Salons, barbers, and rideshare take 15 to 20%. Delivery takes 15 to 20% with a $4 to $5 minimum on small orders. Tip above 20% when service stands out.
How do you calculate a 20% tip in your head?
Move the decimal point one place left to find 10%, then double it. On a $60 check, 10% is $6, so 20% is $12. The same trick works on any bill, and it needs no phone. For a $35 check, 10% is $3.50, so 20% is $7. Practice it once, and the math feels easy at the table.
How do you calculate a 15% tip without a calculator?
Find 10% first, then add half of that amount. On a $60 check, 10% is $6, and half of $6 is $3, so 15% is $9. On an $80 check, 10% is $8, half is $4, and 15% is $12. Halving is the only hard step, and rounding to the nearest dollar keeps it simple.
How much is an 18% tip on a $75 bill?
An 18% tip on $75 is $13.50, so the total is $88.50. Find it in your head: 10% is $7.50, and 8% is $6, so 10% plus 8% gives $13.50. Or use the calculator: enter $75, tap 18%, and the tip and total show at once. Splitting four ways, each person pays $22.13 after rounding, two cents over the total.
