Tip & Bill Split Calculator

What this tool does

You've got the check, a table full of people, and nobody wants to do the math in their head. This calculator figures out the tip, folds in sales tax if you had any, and splits the final total evenly across however many people are paying.

Who it's for

Dinner with friends, a work lunch getting expensed as a group, splitting a bar tab — anywhere a bill needs to be divided fairly and quickly, right from a phone at the table.

How to use it

• Enter the bill amount (and the sales tax amount separately, if your receipt shows it).
• Pick a tip percentage from the quick buttons (10–25%) or type a custom one.
• Set the number of people splitting the check with the +/- buttons.
• Toggle whether tip should be calculated on the bill alone or on the bill plus tax, and whether each person's share should round up to a whole dollar.
• Copy the full summary — bill, tax, tip, total, and per-person amount — with one click.

Real-world examples

A $120 dinner for four people with a 20% tip and $9.60 tax: enter the numbers, and you instantly see each person owes about $37. Splitting a solo takeout order to check what a fair tip actually costs before you order? Set people to 1 and watch the tip amount update live.

Frequently asked questions

Should you tip on the pre-tax or post-tax amount?

Tipping etiquette varies, but most guides suggest tipping on the pre-tax subtotal — that's the default here. Check the "tip on bill + tax" box if you'd rather tip on the full post-tax amount.

What's a normal tip percentage?

In the US, 15–20% is standard for full-service dining, 18–20% is common for good service, and 10% or less is typical for counter service or takeout.

How do I split a bill unevenly?

This tool splits evenly across the number of people you set. For itemized, per-item splitting, add up each person's items separately and divide the shared tax/tip proportionally by hand.

Why round up each person's share?

Rounding up avoids awkward change and covers small math discrepancies — the "round up" option bumps every person's share to the next whole dollar automatically.

Does this work for splitting a bar tab or takeout order too?

Yes — it works for any shared bill: restaurants, bars, group takeout orders, or shared services. Just enter the total and how many people are paying.
