Frequently Asked Questions
How do I calculate a 20% tip?
Multiply the bill by 0.20. For example, a $50 bill with 20% tip: $50 × 0.20 = $10 tip, $60 total. Use the calculator above to set any tip percentage instantly.
How do I split a bill evenly?
Add the tip to the bill total, then divide by the number of people. For example, $80 bill + $16 tip (20%) = $96 total ÷ 4 people = $24 per person.
What is a standard tip percentage?
In the US, 15% is the minimum for adequate service, 18–20% is standard, and 25% or more is for exceptional service. For takeout, 10–15% is common. Tipping customs vary widely internationally.
Should I tip on the pre-tax or post-tax amount?
Most people tip on the pre-tax subtotal, though either is acceptable. This calculator uses the bill amount you enter, so enter the pre-tax total if you prefer to tip before tax.
How do I calculate an 18% tip quickly?
A quick mental shortcut: find 10% (move the decimal left one place), then add nearly double that for 20%, or slightly less for 18%. For exact results, use the calculator above.
