How to use the tip calculator
- Enter the bill, the tip percent and the number of people.
- See the tip, grand total and what each person owes.
How much should you tip?
- 15% — standard service
- 18–20% — good to great service
- 10% — quick counter service (where customary)
Benefits
- Works out the tip, the total and the per-person split in one step.
- Adjustable tip percentage for any level of service.
- Mobile-friendly for use at the table.
- Free and instant.
Limitations to know
- Tipping norms vary widely by country and service — the tool cannot know local custom.
- Rounding an even split can leave the total a cent or two off.
- It does not handle separate itemized checks.
Common mistakes to avoid
- Tipping on the post-tax total when you meant to tip on the pre-tax amount.
- Adding a tip when a service charge is already included in the bill.
- Rounding each share down so the collected total falls short.
