How to split a bill and tip without the awkward maths
The end-of-meal maths does not have to be awkward. Here is the quick way to tip and split a bill fairly.
Enter the bill, choose a tip percentage, and split it between your group.
The bill arrives, someone reaches for their phone, and the table goes quiet while everyone pretends to do mental arithmetic. It does not need to be like that. Splitting a bill and adding a tip is two small steps, and a couple of shortcuts make it painless.
Step one: work out the tip
A tip is just a percentage of the bill. The fastest way to find 10% is to move the decimal one place left, so 10% of a 400 bill is 40. Want 20%? Double it, to 80. Want 15%? Take the 10% figure and add half of it again, so 40 plus 20 is 60. You rarely need anything more precise than that at a dinner table.
How much should you tip?
Tipping customs vary widely around the world, so the "right" tip depends on where you are:
- United States and Canada: 15 to 20% is the norm in sit-down restaurants, and staff often rely on it as income.
- UK and much of Europe: around 10%, or nothing extra if a service charge is already on the bill.
- Japan and a few other countries: tipping is not customary and can even cause confusion.
When in doubt, a glance at how locals do it, or a quick check of the bill, saves you from under- or over-tipping.
Step two: split the total evenly
Add the tip to the bill, then divide by the number of people. A 400 bill with a 10% tip is 440, and split four ways that is 110 each. If the group is paying by card, one person can pay the lot and the rest send their share, which is usually quicker than juggling several cards at the terminal.
How to split a bill with uneven orders
If one person had the steak and another just a salad, an equal split is not fair. The simple fix is to add the tip proportionally: have each person cover their own items, then add the same tip percentage on top of each share. Someone whose food came to 30 adds their 10%, or 3, and pays 33; someone whose food came to 12 pays 13.20. Everyone pays for what they ordered, and the tip stays fair without anyone subsidising the big spender.
Do not forget tax and service charges
Two things quietly change the total. First, in places where tax is added at the till rather than shown on the menu, the figure you divide should be the final total including tax, not the menu prices. Second, check for a service charge before you tip: many restaurants add 10 to 15% automatically for larger groups, and if it is already there, an extra tip is a choice, not an obligation. Reading the bottom of the bill for a few seconds stops you tipping twice.
How to split a bill with an app
If your group uses a payment app, one person can pay the whole bill and collect everyone's share in seconds. Most banking apps (such as Monzo, Revolut or a shared payment request in Google Pay) let you create a split request and send each person a link or a set amount to pay. The trick is to work out the correct per-person figure first, tip included, then request that exact amount, so the app is just moving the money rather than doing the fairness maths for you.
The bottom line
Find 10% by shifting the decimal, scale it to the tip you want, add it on and divide by heads. For uneven groups, split the items and share the tip proportionally, and always check for a service charge first. Our tip calculator does the whole thing at once, including the split per person, so the end of the meal stays relaxed.
Frequently asked questions
How do I quickly work out a 15% tip?
Find 10% by moving the decimal one place left, then add half of that again. On a 400 bill, 10% is 40 and half is 20, so a 15% tip is 60.
How much should I tip at a restaurant?
It depends on the country. In the US and Canada 15 to 20% is standard, in the UK and much of Europe around 10% or nothing if service is included, and in places like Japan tipping is not customary. Check the bill and local norm.
How do I split a bill with uneven orders?
Have each person pay for their own items, then add the same tip percentage on top of each share. That keeps the tip fair without charging the salad-eater for someone else's steak.
How do I split a bill using an app?
Work out each person's share including tip first, then have one person pay the bill and send a split request for that exact amount through a banking or payment app. The app moves the money; you do the fairness maths.
Should I tip if there is a service charge?
Usually not on top. If the bill already includes a service charge, an extra tip is a choice rather than an expectation. Check the bill before adding more so you do not tip twice.
