Should I tip on pre-tax or post-tax amount?

Many people tip on the pre-tax amount but both methods are used. This tool supports tipping on pre-tax or post-tax totals so you can match local etiquette.

How do rounding rules affect per-person split?

Rounding changes the displayed tip or total; per-person splits reflect the rounded total. We also show raw exact values (unrounded) so you can decide which to pay.

Does this calculator handle exact decimals?

Yes — choose the decimal precision (0–6) and the results will be displayed exactly to that precision. Raw unrounded values remain accessible when rounding is used.

Tip & gratuity definitions (quick guide)

Helpful definitions so users understand what each term means and how this calculator computes results.

Tip / Gratuity

Tip (also called gratuity) is a voluntary payment given by a customer to service staff, typically expressed as a percentage of the bill. Common restaurant tips range from 15% to 20% in many countries.

Sales tax

Sales tax is a government-imposed tax added to a bill. Some people calculate tips on the pre-tax amount; others prefer to tip on the post-tax total. This tool supports both methods so you can match local etiquette.

Split per person

Split divides the final total (bill + tax + tip) evenly among the specified number of people. If you round the total or tip, the displayed per-person amount will reflect that rounding.

Rounding rules

Rounding can simplify payments (e.g. round tip up to nearest dollar). When rounding is chosen, this tool shows both the rounded and the exact raw values so you can choose which to pay.

Why use a tip calculator?

Use a tip calculator for quick, accurate tip computation, fair splits, and to compare tipping on pre-tax vs post-tax totals. It avoids mental errors and ensures consistent payments.
