Tip Calculator

How to calculate a tip

Calculating a tip is straightforward: multiply your bill amount by the tip percentage, then divide by 100. For example, on a $60 restaurant bill at 20%, the tip is $12 and your total comes to $72. BehCalc does this instantly and also shows you a total rounded up and rounded down to the nearest dollar — so you always know the cleanest amount to write on the receipt line.

How much should you tip?

Tipping norms in the US generally follow these guidelines:

• 15% — adequate or average service at a sit-down restaurant
• 18% — good service, the widely accepted standard
• 20% — great service, increasingly the new norm
• 25% or more — exceptional service or when you want to show extra appreciation

Tipping by situation

Restaurants: 18–20% of the pre-tax bill is standard. Many people tip on the total including tax — either approach is acceptable.

Food delivery: $3–$5 minimum, or 15–20% of the order total, especially for larger orders or bad weather.

Coffee shops and counter service: $1–$2 per visit, or 10–15% if the order is complex.

Rideshare (Uber/Lyft): $1–$2 for short trips, $3–$5 for longer rides. A 15–20% tip is always appreciated.

Hair salons and barbers: 15–20% of the service cost is standard.

Hotel housekeeping: $2–$5 per night, left daily since staff may rotate.

Should you tip before or after tax?

Most etiquette guides suggest tipping on the pre-tax amount, since tax isn't part of the service. In practice, most people tip on the post-tax total — the difference is small and it's simpler. Either way is fine.

Why round your tip?

Rounding your tip to a whole dollar total makes it easier to fill out a paper receipt quickly and avoids awkward change. BehCalc shows you both options — round up for a slightly more generous tip, round down to keep it conservative — so you can choose what feels right without doing the math yourself.
