How is tip calculated?

Tip is calculated by multiplying the bill amount by the tip percentage. For example, a 20% tip on a $50 bill = $50 × 0.20 = $10 tip, making the total $60.

What is the standard tip percentage in the US?

In the US, standard tips range from 15% to 20% for restaurant service. 15% is considered acceptable, 18–20% is standard for good service, and 25%+ is for exceptional service. For takeout, 10–15% is common.

How do I split a bill evenly?

Enter the total bill amount, set your desired tip percentage, then enter the number of people. The calculator instantly shows the per-person tip and total, dividing everything evenly.

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

Tipping etiquette varies: in the US, tipping on the pre-tax subtotal is technically correct, but many people tip on the total. The difference is usually small — on a $50 meal with 8% tax, the difference between tipping pre-tax vs post-tax at 20% is about $0.80.

Yes. Click the custom input field (next to the preset buttons) and type any percentage you like. The results update instantly.
