Tip Calculator
Enter your bill amount, choose a tip percentage, and optionally split the total across any number of people — get the tip amount, grand total, and per-person share instantly.
How the Tip formula works
Three quick formulas:
Tip amount = Bill × (Tip% / 100) Total = Bill + Tip amount Per person = Total / Number of people
Step-by-step calculation
- Multiply the bill amount by the tip percentage (as a decimal) to get the tip amount.
- Add the tip amount to the bill to get the total.
- Divide the total by the number of people splitting the bill, if more than one.
Worked example
A $84 bill with an 18% tip, split four ways: Tip = 84 × 0.18 = $15.12. Total = 84 + 15.12 = $99.12. Per person = 99.12 / 4 = $24.78.
Frequently asked questions
What's a standard tip percentage in the US?
15–20% is typical for sit-down restaurant service in the US, with 20% common for very good service. Norms vary by country and by service type (delivery, bar service, salons), so adjust for your situation.
Should I tip on the pre-tax or post-tax amount?
Most etiquette guides suggest tipping on the pre-tax subtotal, though many people simply tip on the total for simplicity — either is common practice.
How do uneven splits work if people ordered different amounts?
This calculator assumes an even split. For itemized splitting where each person pays for exactly what they ordered, you'd total each person's items individually and apply the tip percentage to each subtotal.
