Tip Calculator
How This Calculator Works
Tip = Bill Amount × (Tip % / 100); Total = Bill + Tip; Per Person = Total / Number of PeopleA tip calculator quickly determines how much to tip on a restaurant bill or service charge, splits the total among multiple people, and compares tip amounts across different percentages. It eliminates the mental math at the end of a meal so you can focus on enjoying the experience rather than fumbling with numbers.
How the Calculation Works
The core calculation is simple: Tip Amount = Bill Amount multiplied by Tip Percentage divided by 100. If your bill is $85 and you want to leave a 20% tip, the tip is $85 times 0.20 equals $17.00, for a total bill of $102.00. When splitting among multiple people, both the tip and total are divided equally by the number of people.
Preset and Custom Tip Percentages
The calculator offers one-tap preset buttons for the most common tip percentages: 15%, 18%, 20%, 22%, and 25%. If you prefer a different amount, the custom option lets you enter any percentage. The bar chart and comparison table instantly show how different tip percentages affect the total, helping you make a quick, informed decision.
Round Up Feature
The round-up toggle automatically rounds your total bill up to the nearest whole dollar. This is a popular convenience feature — it makes the final number cleaner and usually adds only a few cents to your tip. For example, if the total with tip comes to $102.47, rounding up makes it $103.00, increasing the tip by $0.53.
Pre-Tax Tipping
There is an ongoing debate about whether you should tip on the pre-tax or post-tax amount. Technically, tipping on the pre-tax amount is correct since the tax goes to the government, not the server. However, many people tip on the total for simplicity. If you prefer to tip on the pre-tax amount, enable the pre-tax toggle and enter the tax amount shown on your bill. The calculator will compute the tip based on the bill minus tax, then add it to the full bill for the total.
Splitting the Bill
When dining with a group, the calculator evenly divides the total bill (food plus tip) among all diners. Simply adjust the number of people using the plus and minus buttons or type in the number directly. The per-person total and per-person tip are displayed separately, so everyone knows exactly what they owe.
The Comparison Table
The comparison table at the bottom shows tip amounts, totals, and per-person costs at seven common tip percentages (10% through 30%). Your selected percentage is highlighted in green for easy reference. This table is especially useful when you are unsure what percentage to leave — you can quickly see the dollar difference between, say, an 18% and 22% tip and decide what feels right for the level of service you received.

The Complete Guide to Tipping in America
Tipping culture in the United States is unlike most other countries. While tipping is optional in much of Europe and Asia, it is an essential part of the compensation system for service workers in America. Understanding tipping norms helps you navigate social situations with confidence and ensures the people serving you are fairly compensated.
Standard Tipping Percentages by Service
For sit-down restaurants, 15-20% is the baseline, with 20% increasingly becoming the new standard in many areas. For hair salons and barbershops, 15-20% of the service cost is typical. Taxi and rideshare drivers generally receive 15-20%. Hotel housekeeping should receive $2-5 per night, left daily rather than at checkout. Valets typically receive $2-5 when your car is returned. Movers usually receive $20-50 per mover for a full-day move. For a coffee shop tip jar, $0.50-$1 per drink is generous but not expected.
When Tipping Is Not Expected
You are not expected to tip at fast-food restaurants, retail stores, gas stations, or doctor's offices. Despite the proliferation of tip screens on point-of-sale terminals at these locations, there is no social obligation to tip for counter service where no table service is provided. Similarly, you do not need to tip the owner of a business (such as a salon owner who cuts your hair), though this tradition has relaxed in recent years and many owners now accept tips.
The Math Behind Tipping
If you prefer to calculate tips mentally, here is a quick trick: to find 20%, simply move the decimal point one place to the left and double the result. For an $85 bill: $8.50 doubled is $17.00 — a perfect 20% tip. For 15%, find 10% (move the decimal) and add half of that amount. These mental shortcuts make tipping easy even without a calculator, though having one handy certainly takes the guesswork out of splitting among a group.
