Tip Calculator

How to use the Tip Calculator

Enter your bill amount, pick a tip percentage, optionally add a service charge, and split among multiple people.

  1. Enter the bill amount

    Type the subtotal before tip and service charge in the first field.

  2. Select a tip percentage

    Choose from the quick-select buttons (5%, 10%, 15%, 18%, 20%, 25%) or type a custom percentage.

  3. Add a service charge if applicable

    If the restaurant has already added a service charge, enter it here so the tool accounts for it separately.

  4. Set the number of people

    Use the +/- buttons or type directly. Default is 1 (no split). Enable round-up for clean per-person amounts.

  5. Read the results

    See the tip amount, service charge, total bill, and per-person amount update instantly.

Frequently asked questions

How is the tip amount calculated?

Tip amount = Bill x (Tip% / 100). A 15% tip on a 1,200 bill is 1,200 x 0.15 = 180. The total is 1,200 + 180 = 1,380.

How much should I tip at a restaurant?

Tipping norms vary by country and context. In the US, 15-20% is standard for sit-down restaurants. In the UK, 10-15% is common. In many European and Asian countries, tipping is optional or not expected. Always check local customs when travelling.

What is the difference between a service charge and a tip?

A service charge is a mandatory or near-mandatory levy added by the restaurant to your bill, typically 5-15%. A tip is a voluntary, direct payment from the diner to the staff. If a service charge is already on your bill, additional tipping is usually optional.

Does tipping etiquette differ across countries?

Yes, significantly. In the US, 18-22% is the norm in restaurants. In the UK, 10-15% is standard. In Japan, tipping is not expected and can be considered impolite. In Australia, tipping is appreciated but not mandatory. Always check local custom.

How does the bill split work?

The tool divides the total bill (including tip and any service charge) equally among the number of people. Enter 4 people for a table of 4 and you get the exact amount each person owes. The round-up option bumps each person's share to the nearest 10 for clean cash handling.

How much should I tip for delivery orders?

For food delivery, 10-20% of the order total is common in countries where tipping is customary. Many delivery platforms offer an in-app tip option. Consider tipping more for long distances, bad weather, or large orders.

Should I calculate the tip on the pre-service-charge amount?

Yes, it is standard to tip on the pre-service-charge subtotal (the food and drinks amount), not on the service charge itself. Use the service charge field in this tool to separate them: enter your food bill, enter the service charge percentage, and the tip will be calculated on the base bill only.

What does the round-up option do?

When you are splitting the bill among multiple people, the per-person amount is often a decimal like 687.50. The round-up toggle bumps each share to the nearest 10 (so 690), which makes cash payments practical. The extra rounds up the tip slightly in the server's favour.

Tipping norms, the math, and when a service charge is already included

How to calculate a tip, what percentages are customary across countries, and how to handle service charges on Indian restaurant bills.

Tipping: the math, the norms, and why service charges are not tips

Tipping is a straightforward calculation, but tipping norms vary enormously by country, service type, and even city. Understanding both the formula and the context helps you tip appropriately and avoid double-paying when a service charge is already included.

The formula

Tip amount = Bill x (Tip% / 100)
Total = Bill + Tip
Per person = Total / Number of people

For a 2,400 dinner with a 15% tip split among 4:

  • Tip = 2,400 x 0.15 = 360
  • Total = 2,400 + 360 = 2,760
  • Per person = 2,760 / 4 = 690

In many countries, restaurants add a service charge (typically 5-15%), which appears as a line item on the bill. If a service charge is already included, an additional tip is entirely at your discretion.

The rounding shortcut

For quick mental math: 10% of any bill is just moving the decimal point left one place.

  • 10% of 1,350 = 135
  • 15% = 10% + 5% = 135 + 67.50 = 202.50
  • 20% = 10% x 2 = 270

This works fast enough that you rarely need a calculator, but the tool handles the exact split calculation that mental math struggles with for uneven divides.

When to adjust the tip

Consider going above the standard tip for:

  • Exceptional service or unusual effort
  • Large group bookings (the server handled complexity)
  • Small local restaurants where staff wages are lower

Consider lower or no tip for:

  • Pre-counted service charges already on the bill
  • Self-service or counter-service contexts
  • Genuinely poor service (though speaking to management is usually more productive)
