Tip Calculator

Two calculations, usually done at once

A tip calculation is really two questions stacked. First, how much to add to the bill. Second — almost always, in practice — how to divide the result between the people at the table. Doing the first in your head is easy enough; doing the second while everyone is reaching for their phones is where it falls apart.

This calculator answers both at the same time and updates as you type, so you can adjust the tip percentage and watch the per-person figure move rather than recalculating from scratch each time someone suggests a different number.

Using this tip calculator

Enter the bill, the tip percentage and how many people are splitting it. You get the total tip, the total bill, and the amount per person. Set the number of people to 1 and the per-person rows simply drop away.

There is a sentence mode too, which reads the whole thing as a line of prose — “The bill is ₹100. The tip is 10%. Split among 2 people. That's ₹110 total, or ₹55 each.” It is the quicker one to hand across a table, because the answer arrives already phrased as something you can say out loud.

The arithmetic, worked through

The tip is the bill times the percentage as a decimal; the total is the bill plus that; the per-person figure is the total divided by the number of people.

A ₹100 bill at 10% gives a ₹10 tip and a ₹110 total, which is ₹55 each between two people. At 18% the tip is ₹18 and each person pays ₹59.

The mental shortcut worth learning is the 10% one: move the decimal point one place left. 10% of ₹85.40 is ₹8.54. From there, 20% is that doubled (₹17.08) and 15% is the 10% plus half of it again (₹12.81). Almost every tip you will ever need is reachable from that one move, which is useful when you would rather not get a phone out at all.

How much to tip, and what to tip on

Custom varies enormously by country, and there is no arithmetic that will tell you the right number. In the United States, 15–20% at a sit-down restaurant is the standard range, with 20% now the common default and tipped staff genuinely relying on it. Much of Europe includes service in the price and rounding up is enough. In Japan, tipping is not customary and can be awkward. If you are travelling, the local norm beats any default.

One question that has a clearer answer: tip on the pre-tax amount. Tax is not part of the service, so the conventional and slightly more generous-feeling approach is to apply the percentage to the food and drink subtotal. Many people tip on the total for simplicity, and on a normal bill the difference is small — but on a large one it is not, so enter whichever figure you mean into the bill field.

Splitting an uneven table is the case this calculator does not cover: it divides the total equally. If one person had a ₹400 steak and another a ₹80 salad, work out each share of the subtotal separately and apply the same tip percentage to each — the percentage calculator is the quicker tool for that.
