Tip Calculator
Work out the tip, grand total, and each person's share in seconds.
Example
On a $50 bill with an 18% tip split between 2 people: the tip is $9.00, the total is $59.00, and each person pays $29.50.
How it works
Tip = bill x tip% / 100, and total = bill + tip. The total is then divided by the number of people to get the per-person amount.
Good to know
This Tip Calculator turns three inputs — your bill amount, a tip percentage, and the number of people sharing the check — into four instant figures: the tip itself, the grand total, the tip per person, and the total each person owes. It's built for the quick mental math you'd otherwise do at a restaurant table, in a taxi, or after a haircut or food delivery, and it updates the moment you type or tap, so there's no submit button to press.
Reach for it whenever a group needs to split a bill evenly and you want everyone to pay the same fair share including their slice of the tip. The four preset buttons (15%, 18%, 20%, 25%) cover the most common US service tiers, but you can also type any percentage — including small ones for counter service or zero where tipping isn't customary — and the presets stay in sync with whatever number you enter.
Read the results from the big number down: the large figure is the tip in dollars, then "Total" is what goes on the card, and the two "per person" lines tell each diner their tip share and their all-in share. The split always rounds the head count up to at least one whole person, so fractional or blank entries won't break the math, though dividing a total evenly can leave a cent or two unaccounted for — one person may need to cover the rounding.
A practical caveat: the tool tips on exactly the bill figure you enter, so if you want to follow the common etiquette of tipping on the pre-tax subtotal, type that subtotal rather than the post-tax total. For uneven splits where people ordered very different amounts, this even-split model won't reflect that — calculate each person's tip on their own portion instead.
Frequently asked questions
Should I tip on the pre-tax or post-tax amount?
Etiquette generally suggests tipping on the pre-tax subtotal, but many people tip on the full post-tax total for simplicity. Enter whichever bill amount you prefer in the bill field.
What is a standard tip percentage at a restaurant?
In the US, 15-20% is customary for sit-down service, with 18-20% common for good service and 20-25% for exceptional service. Use the preset buttons to switch quickly.
Is my data uploaded anywhere?
No — this calculator runs entirely in your browser. Your inputs never leave your device, and it works offline once loaded.
Is this calculator free?
Yes, completely free with no sign-up and no limits.
People also ask
How do I calculate a 20% tip quickly in my head?
Move the bill's decimal one place left to get 10%, then double it. For a $50 bill, 10% is $5.00, so 20% is $10.00.
How much should I tip on a $100 bill?
At common US rates, 15% is $15, 18% is $18, 20% is $20, and 25% is $25. The amount you choose typically depends on service quality and local custom.
Do you tip on the total before or after a discount or coupon?
Practice varies; many people tip based on the original pre-discount price to reflect the full service value, while others tip on the amount actually paid. Enter whichever figure you prefer in the bill field.
How do you split a bill and tip evenly among a group?
Add the tip to the bill to get the grand total, then divide that total by the number of people. This calculator does both steps and also shows each person's tip share separately.
What is the tip for delivery or takeout orders?
Tipping norms differ by service: delivery tips are often around 10-20% or a flat few dollars, while takeout tipping is more discretionary. You can enter any custom percentage rather than using a preset.
Is tipping mandatory or just expected?
In the US, tipping is customary rather than legally required for most table service, though some venues add an automatic service charge for large parties. Always check your bill for a charge already included before adding more.
How do I handle an automatic gratuity already added to the bill?
If a service charge is already on the receipt, you generally don't need to add another tip on top. Either leave the tip percent at zero or enter only any extra amount you choose to give.
