Everything about the Tip Calculator
How much to tip, how to figure it mentally, and how to split fairly.
A tip calculator answers the two questions every restaurant table faces: how much do we leave, and what does each person owe? Enter the bill, pick a percentage and a group size, and the tip, grand total and per-person share appear instantly, with the math written out.
The formula is simple: tip = bill × percentage. A $50 bill at 15% means $50 × 0.15 = $7.50, for a total of $57.50. Split between two people, that's $28.75 each.
Mental math trick: move the decimal one place left for 10% ($86.40 → $8.64), then double it for 20% ($17.28) or add half of it for 15% ($12.96).
How much should you tip?
| Service | Typical tip (US) |
|---|---|
| Restaurant, table service | 15 to 20% (18%+ for great service) |
| Food delivery | 10 to 15% (minimum $3 to 5) |
| Bartender | $1 to 2 per drink or 15 to 20% |
| Taxi / rideshare | 10 to 15% |
| Hairdresser / barber | 15 to 20% |
| Hotel housekeeping | $2 to 5 per night |
Splitting the bill fairly
- 1Tip on the pre-tax amount
Etiquette says the percentage applies to the food and drink subtotal, though many people simply tip on the final figure.
- 2Even splits are simplest
Total ÷ people. If the shares differ a lot, split the subtotal by what each person ordered, then add the same tip % to each share.
- 3Check for service charges
Some restaurants add 18% automatically for large groups, so don't tip twice unless service was exceptional.
- 4Round up kindly
Rounding $57.50 to $58 to 60 keeps cash payments simple and servers appreciate it.
Frequently Asked Questions
How do I calculate a tip?
Multiply the bill by the tip percentage as a decimal. For an $80 bill at 18%: 80 × 0.18 = $14.40 tip, so the total is $94.40. This calculator does it live and also splits the total for you.
How much should I tip at a restaurant?
In the US, 15 to 20% for table service is standard: 15% for adequate, 18 to 20% for good service. Counter service is optional (0 to 10%), while delivery usually deserves 10 to 15% with a small minimum.
How do I calculate a 20% tip quickly?
Take 10% by moving the decimal point one place left, then double it. A $64 bill → 10% is $6.40 → 20% is $12.80. For 15%, add half of the 10% figure instead: $6.40 + $3.20 = $9.60.
Should I tip on the pre-tax or post-tax amount?
Traditional etiquette is pre-tax, and no one will fault you for it. Tipping on the post-tax total is slightly more generous, though on an 8% tax the difference at 20% tip is only 1.6% of the bill.
How does splitting the bill work?
The calculator adds the tip to the bill and divides the grand total by the number of people, showing each person's tip share and total share separately, rounded to the cent.
