Understanding Your Results

Enter the bill, the tip percentage and the number of people. You can tip on the subtotal before tax, which is a common practice, or on the total including tax. An option rounds each person’s share up to the next dollar for easy payment.

How to Use the Tip Calculator

  1. Enter the bill subtotal and, if you wish, the tax amount.
  2. Enter the tip percentage.
  3. Choose whether the tip applies to the pre-tax subtotal or the total.
  4. Enter how many people are splitting.
  5. Press Calculate.

Formula

Tip = base × tip %   (base = subtotal or subtotal + tax)
Total = subtotal + tax + tip
Per person = total ÷ people

Example Calculation

On an $85.50 subtotal with no tax listed, an 18% tip is $15.39, making the total $100.89. Split between two people, each pays about $50.45.

What Is a Tip Calculator?

A tip calculator figures out the gratuity and total for a bill and divides it between people. It saves mental math and helps groups settle up quickly.

Tipping Basics

Tipping norms differ by service: restaurants, delivery, taxis, salons and hotel staff each have conventions, and they change over time. When a service charge is already added, you may not need to tip further.

Tip on Pre-Tax or Post-Tax?

Many people calculate the tip on the pre-tax subtotal because tax is not a service cost. Others tip on the total for simplicity. The difference is small, but you can pick either with the selector.

Tips for Splitting a Bill

  • Agree on the tip percentage first.
  • Round up so rounding never shortchanges the server.
  • For separate items, add each person’s items plus a proportional share of tax and tip.

Common Mistakes

  • Adding a tip on top of an automatic service charge without noticing.
  • Forgetting alcohol and shared items when splitting.
  • Calculating on the total with discounts already applied unintentionally.

Frequently Asked Questions

How much should I tip?

Customs vary by service and region. In the U.S., 15–20% is common at sit-down restaurants, though practices differ. Follow local norms.

Should I tip before or after tax?

Both are common. Tipping on the pre-tax subtotal is a widely used approach.

How do I split unevenly?

Calculate each person’s subtotal separately, or use the per-person tip amount as a guide.

What does rounding up do?

It rounds each person’s total up to the next whole dollar, which slightly raises the effective tip.

Does a service charge replace a tip?

Sometimes. Check the receipt, since some service charges do not go to staff.
