Work out the tip and split the bill fairly. Everything runs locally in your browser.
How the tip calculator works
The calculator takes your bill, applies a tip percentage you choose (or one of the quick preset buttons), and shows the tip amount, the new total, and — if you are splitting — exactly what each person owes. The math is simply:
tip = bill × (percent ÷ 100) and per person = (bill + tip) ÷ people
Everything updates the instant you type, so you can try a 15%, 18% and 20% tip side by side before deciding.
Common uses
- Restaurant bills — figure out a fair tip without mental arithmetic.
- Group dining — split one check evenly across the table.
- Takeout and delivery — decide whether and how much to tip.
- Travel — check local tipping norms when the percentage differs from home.
Frequently asked questions
What is a standard tip?
In the US, 15% to 20% is typical for sit-down service, with 18% a common middle ground. Norms vary widely by country.
Should I tip on the pre-tax or post-tax amount?
Either is acceptable; tipping on the pre-tax subtotal is slightly more common, while some prefer the post-tax total for simplicity.
How do I split an uneven bill?
This tool splits the total evenly. For unequal shares, calculate the tip on the whole bill, then divide items individually.
Can I tip a custom percentage?
Yes. Type any percentage into the field rather than using a preset.
What if the service was poor?
Tipping is discretionary. You can lower or skip the tip for bad service, or raise it for exceptional care — the calculator simply does the math for whatever percentage you choose.
Should I round the per-person amount?
The calculator shows exact splits, but in practice you may round to cents and let one person cover the penny difference, or round up slightly so the tip isn’t shortchanged.
