How much to tip, at a glance
For sit-down service in the US, 18–20% of the pre-tax bill is the everyday standard. Use 15% for service that was just okay and 22–25% when someone went out of their way. Counter service and takeout tips are optional.
Not at a restaurant? Movers, hairdressers, tattoo artists and delivery drivers each have their own customs. The tipping guide by service covers them, and it can answer an odd situation for you.

Tip on the subtotal, not the tax
Sales tax goes to the government, not the restaurant. That's why etiquette guides say to tip on the amount before tax. Most card machines and tip screens calculate on the total with tax, so you tip a little more than you meant to. Drag the sliders to see how much.
Tip: $16.00, which is 20% of what you actually ordered. Tipping on the total instead would add $1.42.
Splitting the bill
Set "Split between" to the number of people and TipMath divides the total, tip included. If it doesn't divide evenly to the cent, it tells you who pays the extra cent. Turn on Round up → Per person so everyone pays a whole-dollar amount; the extra goes to the tip.
Didn't everyone order the same? The split bill calculator splits by what each person had and shares tax and tip in proportion. You can also snap a photo of the receipt to fill in the items.
Tips in your head
10% is the bill with the decimal point moved one place left. Double it for 20%. Add half again for 15%. The step-by-step mental math guide walks through it with your own numbers.

Questions people ask
How do I calculate a 20% tip?
Move the decimal point one place left to get 10% of the bill, then double it. On a $64 bill, 10% is $6.40, so a 20% tip is $12.80.
How much is a 20% tip on $61?
$12.20, for a total of $73.20. Quick way: 10% of $61 is $6.10; double it.
How do I calculate a 15% tip?
Find 10% by moving the decimal one place left, then add half of it. On $48: $4.80 + $2.40 = $7.20.
Should I tip on the total with tax or before tax?
Etiquette guides such as the Emily Post Institute recommend tipping on the pre-tax amount. Tick "Bill includes tax" in the calculator and enter the tax from your receipt to tip on the pre-tax amount. The difference is usually under a dollar or two.
How much should I tip at a restaurant?
In the US, 18–20% of the pre-tax bill is standard for table service; 15% is the low end and 22–25% is for excellent service. Toast's Restaurant Trends data puts the average full-service tip at about 19%.
How does the bill split handle leftover cents?
When a total can't be divided evenly, TipMath shows the per-person amount and tells you which one person pays the extra cent or two, so the table covers the bill exactly. You can also round up per person to whole dollars.
Can I send the result to my friends?
Yes. "Share result" copies a link that opens the calculator with the same bill, tip, people and rounding (on phones it opens the share sheet). Nothing is stored on a server: the numbers are in the link.
Is TipMath free? Is there an app?
TipMath is free with no ads for accounts or sign-ups. It works in any phone browser; add it to your home screen from the browser's share menu and it opens like an app.
