Tip Calculator
Calculate tips, split bills, and get per-person amounts with preset or custom tip percentages.
What is a Tip Calculator?
A tip calculator is a practical tool that helps you calculate gratuity on a bill and split the total between multiple people. It takes the bill amount, applies a tip percentage (preset or custom), and shows you the tip amount, total bill, tip per person, and total per person. This eliminates mental math and ensures fair splitting.
Gratuities are typically expressed as a percentage of the bill amount. Common percentages range from 10% for basic service to 25% or higher for exceptional service. The calculator computes the tip by multiplying the bill amount by the tip percentage, then adds it to the bill for the total. When splitting, both the tip and total are divided evenly by the number of people.
This tool uses straightforward arithmetic: tip = bill × (tip percentage ÷ 100), total = bill + tip, tip per person = tip ÷ split count, and total per person = total ÷ split count. All results are formatted as currency with two decimal places for clarity.
Whether you're dining out with friends, paying for a group meal, or calculating service charges, this calculator gives you quick, accurate numbers so everyone pays their fair share.

Tips and Common Mistakes
- Pre-tax vs post-tax — Most people tip on the pre-tax amount, but tipping on post-tax is more generous. Be consistent with local norms.
- Rounding per person — When splitting, the calculator divides exactly; you may want to round cash amounts slightly for convenience.
- Minimum splits — Split count cannot be less than 1. The calculator enforces this.
- Custom percentages — You can enter decimal values (e.g., 18.5%) for precise tipping.
- Currency precision — Results are shown to two decimal places. Behind the scenes, calculations use floating point for the displayed precision.
- Service context matters — Tip percentages vary by country, service type, and group size. Use appropriate percentages for your situation.
