Tip Calculator
Calculate a restaurant tip, the final bill, and an equal per-person share in one step. Enter the amount before tip, choose a percentage, and add the number of people sharing. The calculator does not assume a local tipping custom, tax treatment, or service charge; enter the amount and percentage you actually want to use. Results stay in this browser tab, and the visible working makes it clear whether the tip is included in the total.

How to use Tip Calculator
- 1
Enter the bill
Use the pre-tip amount and include any items that should participate in the gratuity calculation.
- 2
Choose the percentage
Enter the tip rate as a percentage, such as 15, 18, or 20, rather than a decimal fraction.
- 3
Split if needed
Enter the number of people to see the total divided equally; uneven contributions need a separate arrangement.
How it works
The tip is bill × percentage ÷ 100. The total is the bill plus that tip, and
the equal share is the total divided by the number of people. Currency is
displayed to two decimal places while the arithmetic runs at full precision, so
the shares always add back up to the total.
It infers nothing. No tax is added or removed, no service charge is assumed and no customary rate is suggested — the percentage applied is the one you choose, to the amount you enter. That is deliberate: tipping custom varies by country, venue and occasion, and a calculator that guesses at it is making an etiquette argument disguised as arithmetic.
Working it out in your head
The arithmetic is easy once you see it as one step rather than a percentage problem, and it is worth knowing because the moment you need it is usually the moment the phone is in someone else's hand.
Find ten percent first. Move the decimal point one place left. A $64.80 bill has $6.48 in it. Everything else is built from that number.
- 20% — double it. $12.96.
- 15% — take the ten and add half of it. $6.48 + $3.24 = $9.72.
- 18% — double the ten, then subtract a tenth of the ten. $12.96 − $0.65, near enough $12.30.
Splitting comes after, not before. Work out the tip on the whole bill, add it, then divide. Dividing first and tipping each share separately gives the same answer in theory and a different one in practice, because each rounding error is multiplied by the number of people.
For a table of four on that $64.80 bill at 20%: $6.48, doubled is $12.96, total $77.76, each person $19.44.
The calculator above is the version that does not require you to trust your arithmetic at the end of an evening, and it shows its working so the table can check it.
Before you pay
Check whether the bill already includes a service charge or an automatic gratuity for large groups — adding a second tip on top is the most common and most expensive mistake here. If a discount or voucher changed the amount, decide whether the tip follows the price before or after it; there is no universal rule, only the one you intend to apply.
If one person pays and the others transfer their share, keep the receipt and the agreed percentage with the request. It settles the rounding argument before it starts, and it makes clear whether the split covered tax and service or only the food.
For a table where people ordered very differently, an equal split is a convenience, not a fair answer. Total each person's items, then allocate tax and tip in the same proportion.
Examples
Twenty percent on an $85 bill
The tip is calculated from the bill before it is added to the total.
Sharing dinner with friends
Equal splitting assumes everyone shares the same total; it does not reconcile separate meals.
Frequently asked questions
Should I calculate the tip before or after sales tax?
That depends on the custom, venue, and preference in your location. This tool applies the percentage to the bill amount you enter and does not add tax or remove it automatically. Decide whether your input includes tax, then use the result as a transparent arithmetic calculation rather than an assumption about etiquette.
Does splitting the bill handle uneven meals or cash rounding?
No. It divides the final total equally among the people value. If diners ordered different items, assign each person their items and a fair share of tax and tip separately. Cash rounding, service charges, and local payment rules also need to be handled after the displayed calculation.
Is the tip calculator storing my bill amount?
No. The arithmetic runs in the browser and the page does not send the numbers to a server. The result is still visible on your device screen, so clear it before handing over a shared phone or taking a screenshot that includes private receipt details.
How do you calculate a tip?
Multiply the amount before tip by the percentage you mean to leave: twenty percent of a $60 bill is $12, for a $72 total. This page does that and divides the result by the number of people sharing, so the gratuity, the final bill and the per-person share all appear together. It assumes no local custom, tax treatment or service charge, because the percentage is yours to choose.
