📌 About Everyday & Lifestyle

Some of the most-used math in daily life is the quick mental kind we still get wrong under pressure — figuring a fair tip at dinner, splitting a bill among friends, or rounding to a clean total. These calculators take the awkward guesswork out of the moment so you can tip fairly and split evenly.

Each tool shows exactly how the number was built, including the per-person share when you split. Use them at restaurants, bars, salons and for delivery, where US tipping norms vary by service and the bill rarely divides evenly.

  • Calculate a tip by percentage on any bill
  • Split the total and the tip evenly among any number of people
  • See the per-person amount instantly
  • Use common US tip rates (15%, 18%, 20%) by service type
  • Round the total up to a clean number
  • Tip on the pre-tax or post-tax amount, your choice

❓ Frequently asked questions

How much should I tip at a restaurant?

In the US, 18–20% of the pre-tax bill is standard for sit-down restaurant service, 15% for adequate service, and more for exceptional service. The tip calculator lets you pick a rate and splits it per person.

How do I split a bill with a tip?

Add the tip to the bill, then divide by the number of people. The tip calculator does both at once and shows each person's exact share.

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

Customarily you tip on the pre-tax subtotal, though tipping on the full total is also common and only adds a little. The calculator lets you choose which base to use.

How much do I tip for delivery or at a bar?

Food delivery is typically 10–15% (or a $3–5 minimum), and bartenders usually get about $1–2 per drink or 15–20% of a tab. Adjust the rate in the calculator to match.
