Tip Calculator: Complete Guide
Learn how much to tip, how to calculate a tip by hand, how to split a bill, and common tipping mistakes. Covers US norms and international customs.
Quick Answer
This gratuity calculator works out the tip amount, the total bill after tip, and the per-person cost for bill splitting. Enter the bill, tip percentage, and number of people. On a $60 bill with a 20% tip split three ways: tip = $12, total = $72, per person = $24. Tip calculation runs instantly with no account required.

In the United States, standard restaurant tips are 15-20% for good service. Excellent service warrants 20-25%. Counter service and takeout orders receive 10-15%. Delivery drivers get 15-20% on the food subtotal, with a minimum of $3-5 for small orders since the fixed cost of a trip does not scale with order size.
For a sit-down restaurant: a $45 bill at 20% tip = $9 tip, $54 total. For a $120 group dinner at 18% = $21.60 tip, $141.60 total. At a coffee counter for a $6 drink: $0.60-$0.90 at 10-15%. The calculation is the same at every price point.
Other services where tipping is standard in the US: hair and nail salons (15-20%), taxi and rideshare (15-20%), hotel housekeeping ($2-5 per night), movers (5-10% of the total bill), tour guides ($5-15 per person). These are conventions, not laws; adjust based on service quality.
Tipping customs differ significantly outside the US. Japan: tipping is not customary and can be considered rude. Most of Europe: a small tip or rounding up is appreciated but not required, and service charges appear on many bills automatically. Australia and New Zealand: tipping is not expected but welcomed. Always check local customs before traveling to avoid awkward exchanges.
How Does a Tip Calculator Work?
This gratuity tool takes three inputs: bill amount, tip percentage, and number of people. It computes the tip as (Bill × Percentage) ÷ 100, adds it to the bill for the grand total, then divides the grand total by the number of people for the per-person share. As a bill splitter, it always divides the full total (bill plus tip), not just the pre-tip bill.
The fastest mental method for 20%: move the decimal one place left to find 10%, then double it. On a $47 bill: 10% = $4.70; 20% = $9.40. Round up to $9.50 if service was good.
For 15%: find 10% and add half. On a $47 bill: 10% = $4.70; half of that is $2.35; 15% = $7.05. Round to $7.
How Do You Split the Bill Evenly?
Add the tip to the bill total first, then divide by the number of people. On a $90 bill with a $18 tip (20%): grand total = $108; split among 6 people = $18 each.
A common mistake is splitting the pre-tip bill, then asking each person to add their share of the tip separately. This works but creates friction. Adding the tip first and splitting the grand total is cleaner: everyone pays one number.
For uneven splits, where people ordered different amounts, calculate each person's fraction of the pre-tip subtotal and apply that fraction to the tip as well. The tip calculator handles even splits automatically.
Does the Tip Apply Before or After Tax?
A tip percentage applies to the bill before tax is added, not the total with tax already included. The server provided the service at the pre-tax price; the tax is a government charge. Standard advice is to base tip calculation on the pre-tax subtotal.
On a $100 pre-tax bill with 10% sales tax ($10 tax): pre-tax 20% tip = $20; post-tax 20% tip = $22. The gap is $2. For everyday restaurant visits, the difference is small and rounding up to the post-tax total is common. For large catered events at $2,000 pre-tax, the $40 difference becomes meaningful.
Tip Calculation Examples
Common scenarios with worked numbers. For example:
- Two people, dinner. Bill: $74. 20% tip: $14.80. Total: $88.80. Split two ways: $44.40 each.
- Group of five, restaurant. Bill: $135. 18% tip: $24.30. Total: $159.30. Per person: $31.86.
- Delivery order. Food subtotal: $28. 20% tip: $5.60. Total including tip: $33.60. (Delivery fees listed separately do not replace the tip.)
- Comped item. Original bill: $80, one item comped leaving $55 charged. Tip on full $80 pre-discount: $16. Paying $55 plus $16 tip = $71 total.
