チップ計算機

This free tip calculator helps you determine the tip amount, total bill, and per-person share for your group.

What is a Tip / Gratuity?

A tip is a voluntary payment to a service worker as recognition of good service. Customs vary widely by country and culture. This calculator works for any scenario where you need to calculate and split a service-related payment.

Formula:

Tip Amount = Bill × (Tip% ÷ 100) Total = Bill + Tip Per Person = Total ÷ Number of People

The Round-Up Method

When paying cash, rounding each person’s share up to the nearest whole currency unit simplifies the payment. Our calculator shows both exact and rounded amounts.

How to Use

Enter the bill amount (subtotal before tip).
Set the tip percentage (15–20% is standard in the US; adjust for local customs).
Enter the number of people sharing the bill.
Toggle round-up for easy cash payment.
Click Calculate.
