How to Use

  1. Enter the bill amount (use pre-tax for standard tipping, post-tax for simplicity).
  2. Select a quick-select tip percentage or enter a custom amount.
  3. Enter the number of people splitting the bill.
  4. Review tip amount, total bill, and per-person split (exact and rounded).
  5. Toggle tax mode if you want to tip on pre-tax or post-tax amount.
  6. Use the round-up feature to see what clean total each person needs to pay.
  7. Check effective tip percentage if you plan to pay a round total.

Calculator Overview

The Tip Calculator computes gratuity amount, total bill, and per-person split for any restaurant, service, or hospitality bill. Enter the pre-tax bill, tip percentage, and number of people splitting, and the calculator instantly returns the tip per person, total per person, and grand total โ€” with a rounding option so everyone pays a clean amount.

Tipping norms vary by country, service type, and bill size. In the United States, 15-20% is the standard restaurant tip for table service. 20% is considered good. 18% is commonly added automatically for large parties. At coffee shops and counter service, 10-15% is typical if you tip at all. For delivery drivers, $3-5 per delivery or 15-20% of the order total is standard, with higher amounts for large orders or bad weather.

This calculator supports custom tip percentages for any situation. Tipping hotel housekeeping ($3-5 per night), airport porters ($2-3 per bag), rideshare drivers (10-15%), salon stylists (15-20%), and taxi drivers (10-15%) all have different conventions. Enter any percentage you choose and the calculator handles the rest.

For group dining, the split calculation eliminates the awkward table math. If a $127 bill with 18% tip needs to be split among 5 people, the calculator shows both the exact per-person amount and a rounded version (e.g., $30.05 exact vs. $31 rounded up to cover any change). You can also choose to split tip but not split the bill, or handle uneven item purchases.

The calculator also shows the effective tip percentage when you enter a round total. If you plan to pay $150 on a $122 tab, the calculator tells you the implied tip percentage (23%) and tip amount ($28) โ€” useful when you want to leave a clean number without doing backward math.

Tax-inclusive vs. tax-exclusive tip is a common point of confusion. Some people tip on the pre-tax amount; others tip on the post-tax total. This calculator supports both modes. Tipping on the pre-tax amount is mathematically correct (you are rewarding service, not tax), but tipping on the total is simpler mentally. The difference for a typical 8% tax rate is about 1.6 percentage points on the effective tip.

Formula and Step-by-Step Example

Tip calculation uses straightforward percentage arithmetic with optional rounding for group splits.

Core formulas Tip Amount = Bill ร— (Tip % / 100) Total Bill = Bill + Tip Amount Per Person = Total Bill / Number of People Per Person Tip = Tip Amount / Number of People

Reverse calculation (from total to tip rate) Tip Amount = Total โˆ’ Bill Tip % = (Tip Amount / Bill) ร— 100

Rounding for group splits Round per-person amount up to the nearest dollar to ensure full total is covered. If per-person exact = $23.85, round to $24.00. Overage = $0.15 ร— n covers any rounding differences.

Worked example Bill: $85 | Tip: 20% | 4 people Tip Amount = $85 ร— 0.20 = $17.00 Total = $85 + $17 = $102.00 Per person = $102 / 4 = $25.50 Rounded up: $26.00 per person

Reverse example: Paying $100 on an $82 bill Tip = $100 โˆ’ $82 = $18 Tip % = ($18 / $82) ร— 100 = 21.95%

FAQ

How much should I tip at a restaurant?

15% is the minimum for adequate service in the US, 18-20% is standard for good service, and 25%+ is appropriate for exceptional service. For buffets, 10% is typical since service is limited. For counter service and fast casual, tipping is optional (10-15% if you choose).

How do you calculate a tip percentage?

Multiply the bill amount by the tip percentage divided by 100: Tip = Bill ร— (Tip% / 100). For a $60 bill at 20%: $60 ร— 0.20 = $12 tip. Total = $72.

How do you calculate a 15% tip quickly in your head?

Find 10% by moving the decimal (10% of $48 = $4.80), then add half of that for 15% ($4.80 + $2.40 = $7.20). For 20%, just double the 10% figure ($4.80 ร— 2 = $9.60).

Should you tip on the pre-tax or post-tax amount?

Tipping on the pre-tax amount is technically correct โ€” you are rewarding service, not the government's tax. However, tipping on the total is simpler and widely accepted. For a typical 8% sales tax, the difference is about $0.80 on a $50 bill at 20% tip โ€” minor in practice.

How much do you tip on a $100 bill?

At 15%: $15. At 18%: $18. At 20%: $20. At 25%: $25. If the service was excellent, 20-25% is appropriate. For average service, 15-18% is standard.

How do you split a tip evenly?

Calculate total tip (Bill ร— Tip%), then divide by number of people: Tip per person = Tip Amount / People. Or calculate the total bill per person: (Bill + Tip) / Number of People.

What is the standard tip for food delivery?

In the US, $3-5 minimum per delivery, or 15-20% of the order total, whichever is higher. Tip more for large orders, bad weather, long distances, or when drivers need to wait. Many drivers rely on tips as a significant portion of their income.

Do you tip when gratuity is already included?

No โ€” if the bill shows gratuity or service charge already added (common for parties of 6+), you do not need to add more. Check your bill carefully. Additional tipping is at your discretion for exceptional service but is not expected or required.

How much do you tip a hairdresser?

15-20% of the service cost is standard for hairdressers, barbers, and salon stylists. For exceptional work or a long appointment, 20-25% is appropriate. If the salon owner performs the service, tipping is still appreciated and common, though technically optional.
