Tip formula
Without rounding, tip = tip basis × tip percentage. The final total is bill plus tax plus tip. Tip per person and total per person divide those amounts by the number of people. Pre-tax tipping uses the original bill as the basis; after-tax tipping uses bill plus entered tax.
Tip and bill-split example
For a $120 pre-tax bill, $10 tax and a 15% pre-tax tip, the tip is $18 and the final total is $148. Split four ways, each person pays $37. Using an after-tax basis would make the tip $19.50 and the total $149.50.
Rounding the tip or total
The tool can round the tip up, round the total up or round each person up to a whole currency unit. Rounding each share upward changes the effective tip percentage because the rounded group total may be higher than the unrounded bill.
Splitting fairly
An equal split is convenient when everyone shares similar items. If guests ordered very different amounts, calculate individual subtotals first and allocate shared charges separately. The calculator divides the final amount equally and does not itemize a receipt.
Important limitations
- Local customs: the tool does not recommend a tip percentage.
- Service charges: confirm whether gratuity is already included.
- Tax basis: tipping practices before or after tax vary.
- Rounding: whole-unit choices intentionally change the exact percentage.

Tip Calculator FAQ
How do I calculate a 15% tip?
Multiply the selected tip basis by 0.15. The calculator then adds tax and the tip to the bill.
Should I tip before or after tax?
Customs differ. Choose the basis that matches local practice or your preference.
Can I split the bill between several people?
Yes. Enter a whole number from 1 through 100 for an equal split.
Does rounding change the tip percentage?
Yes. Rounding the tip, total or each share can change the effective rate.
What if gratuity is already included?
Check the receipt before adding another tip; included service charges are not detected automatically.
Are bill details uploaded?
No. The calculation runs locally in your browser.
