Tipping can be confusing, especially when you're splitting a bill with friends or colleagues. This calculator eliminates the mental math by instantly computing the tip amount, total bill, and per-person share. It's designed for restaurant checks, bar tabs, taxi fares, food delivery, and any situation where you need to add a tip and potentially split the cost.
The calculator offers five standard tip percentages (10%, 15%, 18%, 20%, 25%) as quick-select buttons, plus a custom option for any percentage. The default is 18%, which aligns with common US tipping standards for table service. Results update in real time as you type, so there's no need to click a calculate button — though the button is there if you want it.
In the United States, tipping is a significant part of service industry compensation. Standard restaurant tipping ranges from 15% (acceptable) to 20% or more (excellent service). For counter service, takeout, and coffee shops, 10–15% is customary. Tipping customs vary internationally — some countries include service charges in the bill, while others consider tipping unnecessary or even rude.

Frequently Asked Questions
How do I calculate a tip?
Multiply the bill amount by the tip percentage. For example, on a $50 bill with a 20% tip: $50 × 0.20 = $10 tip. The total is $60. This calculator does the math automatically — just enter the bill amount and select your preferred tip percentage from the quick buttons or enter a custom value.
What's a good tip percentage?
In the United States, standard tipping is 15–20% of the pre-tax bill for restaurant service. 15% is considered acceptable, 18% is good, and 20%+ is generous for excellent service. For counter service or takeout, 10–15% is common. Tipping customs vary significantly by country — always research local norms when traveling internationally.
How do I split the bill?
Enter the number of people in the "Split Between" field, and this calculator automatically divides the total (bill + tip) evenly across everyone. The per-person amount includes both the food/drink cost and each person's share of the tip. For uneven splits, you can adjust individual portions manually.
Should I tip before or after tax?
Traditional etiquette says to calculate the tip based on the pre-tax subtotal, not the total including tax. However, many people tip on the post-tax amount out of convenience, and most point-of-sale systems make it easy to tip on the full amount. This calculator uses whatever bill amount you enter — if you want to tip on the pre-tax amount, enter that number.
Do different countries have different tipping customs?
Yes, tipping customs vary widely around the world. In the US, 15–20% is standard for restaurant service. In many European countries, a 5–10% service charge is often included in the bill. In Japan and South Korea, tipping can be considered rude. In Australia and New Zealand, 10% is common for good service. In some Middle Eastern countries, a service charge is added to the bill. Always research local customs when traveling internationally.
