Tip Calculator
This free tip calculator figures out exactly how much to tip and how much everyone owes when splitting a bill. Enter the bill amount, pick a tip percentage (or enter your own), and the number of people splitting the check, and the tip amount, total, and per-person share update instantly. Useful for restaurants, delivery, salons, or any group bill.
How to Use It
- Enter the bill amount.
- Choose a preset tip percentage (10/15/18/20/25%) or enter a custom percentage.
- Enter the number of people splitting the bill (1 to 20).
- The tip amount, total, and amount per person update instantly as you change any value.
How It Works
The calculator applies your chosen tip percentage to the bill amount to get the tip amount, adds that to the bill for the total, then divides the total evenly by the number of people splitting it. All the math happens the moment you type. There's no submit button, so you can adjust the bill, tip, or party size and watch every number update immediately.
Formulas
tip amount = bill × (tip % ÷ 100)
total = bill + tip amount
amount per person = total ÷ number of people
Preset buttons (10/15/18/20/25%) cover the most common tipping percentages, but you can always type an exact custom percentage instead, which is useful for tipping on an odd amount, or matching a specific service charge.
A worked example: an $85.40 bill with a 20% tip comes to $17.08 in tip, for a total of $102.48. Split four ways, that's $25.62 per person. Each step (tip, total, per-person share) recalculates the moment any of the three inputs changes.
Everything runs client-side in your browser. No bill amounts are sent anywhere or stored.
Frequently Asked Questions
What is a standard tip percentage?
In the US, 15% to 20% is standard for restaurant table service, with 20%+ increasingly common for good service. Food delivery typically gets 10% to 20% (or a flat $3 to $5 minimum for short trips), and salons/barbers are usually tipped 15% to 20% as well. These are conventions, not requirements. Always tip according to your own budget and the service received.
Should I tip on the pre-tax or post-tax total?
Tipping on the pre-tax subtotal is the more traditional convention, since it reflects the cost of the service itself rather than local sales tax. In practice, many people just tip on the post-tax total for simplicity, and the difference is usually small. This calculator lets you enter whichever bill amount you'd like to tip on.
How do I split a bill evenly between a group?
Enter the total bill amount and your chosen tip percentage, then enter the number of people splitting the bill. The calculator divides the bill plus tip evenly across everyone and shows the amount each person owes.
What if I want a tip percentage that isn't one of the presets?
Use the "Custom %" field next to the preset buttons. Enter any percentage and the results update immediately.
What if the total doesn't divide evenly between everyone?
The calculator shows the exact per-person amount to the cent, which often won't be a perfectly round number when splitting between an odd number of people. In practice, most groups either round each person's share up slightly (so the group collectively covers any rounding gap) or have one person cover the small difference. The calculator shows the precise math either way.
Is tipping customary outside the US?
It varies a lot by country. Tipping is deeply embedded in US service industry pay norms, but many countries (much of Europe, Japan, South Korea) either don't expect a tip at all or already include a service charge in the bill, and in some places, offering a tip can even come across as awkward. If you're traveling, it's worth checking local convention rather than assuming the US-style 15-20% norm applies.
What if the service was poor? Should I still tip the standard percentage?
That's a personal call this calculator doesn't make for you. Some people adjust the percentage down for poor service using the same custom tip field, others tip the standard rate regardless since it may reflect a kitchen or systemic issue rather than the server's effort. There's no single "correct" answer, only local convention and your own judgment.
