Frequently Asked Questions

In the United States, the standard tip for restaurant service is 15-20% of the pre-tax bill. For excellent service, 20-25% is appreciated. For takeout or counter service, 10-15% is common. In many other countries, tipping customs vary — in some countries like Japan, tipping is not expected, while in Europe, 5-10% is typical. Always check local customs when traveling.
To split a restaurant bill fairly: first calculate the total bill including tip, then divide by the number of people. For an even split, everyone pays the same amount. If splitting by what each person ordered, calculate each person's subtotal, add the proportional tip to each, and sum up. This calculator helps you quickly determine the per-person amount when splitting evenly.
A 20% tip is calculated by multiplying the bill amount by 0.20. For example, on a Rs. 1,000 bill, a 20% tip would be Rs. 200, making the total Rs. 1,200. On a $50 bill, a 20% tip would be $10, making the total $60. This calculator lets you quickly see the tip amount for any bill and any percentage.
Technically, tip should be calculated on the pre-tax bill amount, since tax is a government charge and not part of the service provided. However, many people calculate tip on the total (post-tax) bill for simplicity. The difference is usually small. This calculator uses the bill amount you enter, so you can use either the pre-tax or post-tax amount as you prefer.
