What Is a Bill Split Calculator?
A bill split calculator helps you quickly and fairly divide a restaurant bill, group expense, or shared cost among multiple people. Instead of fumbling with mental math or phone calculators at the table, this tool instantly shows each person's share including tip.
How to Use This Bill Split Calculator
- Enter the total bill amount before tip
- Set the number of people sharing the bill
- Optionally add a tip percentage (common rates: 10%, 15%, 18%, 20%)
- Select your currency and click Calculate
How It Works
Per Person = (Bill + Bill × Tip%) ÷ Number of People
The calculator first applies the tip percentage to the subtotal to get the grand total, then divides equally among all participants. Amounts are rounded to two decimal places (or whole numbers for currencies like JPY and KRW).
Tipping Customs Around the World
Tipping practices vary widely. In the United States, 15-20% is standard for restaurant service. In Japan and South Korea, tipping is generally not expected and can even be considered rude. In many European countries, a small tip of 5-10% is appreciated but not mandatory. This calculator accommodates all customs by letting you set any tip percentage, including zero.
Frequently Asked Questions
Should I calculate the tip before or after tax?
Traditionally, tip is calculated on the pre-tax amount. Enter your pre-tax subtotal as the bill amount for the most accurate calculation. However, many people tip on the post-tax total for simplicity — either approach is acceptable.
What if people ordered different amounts?
This calculator handles equal splits. If some people spent significantly more, you may want to have each person calculate their individual share plus their portion of the tip. A good rule of thumb: split equally unless the difference exceeds 30% of the average.
How do I handle rounding when splitting?
The calculator rounds to two decimal places. In practice, one person may need to cover a few extra cents to account for rounding. Many groups simply round up each share to the nearest whole number for convenience.
