About the Gratuity Calculator
Gratuity is the tip you add to a bill to reward good service, and working it out in your head while everyone waits is rarely anyone’s favourite moment. This gratuity calculator does it instantly: enter the bill amount, pick the percentage you want to leave, and it shows the gratuity, the new total, and — if you are dining as a group — each person’s share.
Customs vary, so the calculator lets you set any percentage rather than assuming one. In the United States a gratuity of 15–20% is typical for restaurant service; in many other countries a smaller amount or simple rounding up is the norm, and some bills already include a service charge. Being able to dial in the exact rate means the tool works wherever you are and however you like to tip.
It is especially handy for splitting the total fairly across a table, with an option to round to a tidy figure so the payment is easy. Everything is worked out in your browser the moment you type, with nothing stored.

Frequently Asked Questions
How do I calculate gratuity on a bill?
Multiply the bill amount by the gratuity percentage expressed as a decimal — for example, 18% gratuity on a $50 bill is 50 × 0.18 = $9, for a $59 total. This calculator does it instantly and also splits the total across however many people are paying.
Should gratuity be calculated before or after tax?
Conventions differ. Many people calculate gratuity on the pre-tax subtotal, while others simply apply it to the final total for speed. Either is acceptable — enter whichever figure you prefer as the bill amount, and the calculator applies the percentage to it.
How much gratuity is customary?
It depends heavily on the country and setting. In the US, 15–20% is standard for sit-down restaurant service; elsewhere a smaller percentage, rounding up, or nothing at all may be normal, and some bills add a service charge already. The calculator lets you set any rate to match local custom.
Understanding Gratuity and Tipping
What gratuity is and when it applies
Gratuity, or a tip, is a discretionary amount added to a bill to reward service. It is most associated with restaurants but also appears for taxis, hairdressers, hotel staff and delivery. In some industries and countries it forms a meaningful part of workers’ income; in others it is a small token or not expected at all. Knowing the local norm helps you tip appropriately without over- or under-paying.
Percentage tips versus service charges
A percentage tip is calculated from the bill, so it scales with the amount spent. A service charge is different: it is a fixed percentage the venue adds automatically, often for larger groups, and when present an additional tip may be unnecessary. Always check the bill for an existing service charge before adding gratuity so you do not pay twice for the same thing.
Splitting the bill fairly
When a group shares a meal, the simplest fair approach is to total the bill, add the chosen gratuity, then divide by the number of people — exactly what this calculator does. Rounding each share up slightly makes payment easier and ensures the tip is fully covered. For very uneven orders, some prefer to split by what each person had, then add gratuity proportionally.
