How to use this calculator

  1. Choose your currency. It changes formatting only, not the maths.
  2. Enter your bill subtotal, or turn on My bill already includes tax and enter the total shown before any extra tip.
  3. Enter the number of people splitting the bill equally.
  4. Choose a tip percentage or a fixed tip amount. The quick percentage buttons are examples you can pick from — choose whichever suits you.
  5. In percentage mode, choose what the percentage applies to — the bill subtotal, or the subtotal plus tax and any service charge.
  6. Open Add tax, service charge or rounding to enter tax, add a service charge or automatic gratuity already on the bill, and choose whether to round the total or each person's share.
  7. Read the tip, total, each person's share and the full bill and per-person breakdown below the form.

How is the tip and split calculated?

The tip is a percentage of the chosen tip base, or a fixed amount you enter directly. The total is the bill plus any tax, any service charge and the tip, and each person's share is that total divided evenly by the number of people.

tip = tip base × tip percentage ÷ 100
  • total = bill subtotal + tax + service charge + tip
  • each person pays = total ÷ number of people
  • tip base is your choice: the subtotal, or the subtotal plus tax and service charge
  • a bill that already includes tax is not taxed again
  • rounding, if chosen, is applied only after this exact calculation

For example, on an £80 bill with a 15% tip calculated on the subtotal, no tax and no service charge: the tip is £80 × 15 ÷ 100 = £12, the total is £80 + £12 = £92, and split between 4 people, each person pays £92 ÷ 4 = £23, of which £3 is their share of the tip.

Tip base, tax and service charge, explained

The tip base is the amount a percentage tip is calculated on. This calculator always shows you the tip base explicitly rather than assuming one, because reasonable people calculate this differently. A service charge or automatic gratuity that a venue has already added is kept separate from any extra tip you choose to leave — the two are never combined without both figures being shown.

How does rounding work?

Rounding is always applied after the exact bill, tip and split have been calculated, never before. Rounding the total or each share up collects a little more than the exact amount owed, and this calculator shows the adjustment. Rounding each share to the nearest whole unit can instead collect slightly less than the bill — this calculator flags that shortfall so you know before you pay.

Frequently asked questions

How do I calculate a tip?

Multiply the tip base by the tip percentage and divide by 100: tip = tip base × tip percentage ÷ 100. For example, a 15% tip on a £80 bill is £80 × 15 ÷ 100 = £12. This calculator does the working for you and lets you choose whether the percentage applies to the bill subtotal, or to the subtotal plus tax and service charge.

How do I split a bill with a tip?

Add the bill, any tax, any service charge and the tip together to get the total, then divide the total by the number of people: total = bill + tax + service charge + tip, and each person pays = total ÷ number of people. This calculator splits the total evenly and also shows each person their share of the bill, tax, service charge and tip separately.

Should I tip before or after tax?

This is a personal or local choice, not a fixed rule, and customs vary by country and venue. This calculator lets you choose the tip base explicitly — the bill subtotal before tax, or the subtotal plus tax — so you can calculate it either way.

What is the difference between a service charge and a tip?

A service charge or automatic gratuity is an amount some venues add to the bill automatically, often shown as a fixed percentage. A tip is an additional amount you choose to leave yourself. This calculator keeps the two separate in every figure, so an extra tip is never combined with an existing service charge without you seeing both amounts.

Can I split a bill unevenly, based on what each person ordered?

Not with this calculator. It only splits the bill, tax, service charge and tip equally between the number of people entered. It does not itemise individual orders or split a bill by what each person had.

Why does rounding change the total?

Rounding the total or each person’s share up to a whole currency unit means slightly more is collected than the exact amount owed, and the calculator shows this as a rounding adjustment. Rounding each share to the nearest whole unit can instead collect slightly less than the total, which the calculator flags as a shortfall so you can round up instead or ask one person to cover the difference.

Does this calculator tell me how much I should tip?

No. It only calculates the amounts from the percentage or amount you choose. The quick percentage buttons are examples to select from, not a recommendation, and this calculator does not know local tipping customs, whether a service charge is mandatory, or any tax rules for your country.

Can I use a bill that already includes tax?

Yes. Turn on "My bill already includes tax" and enter the total shown before any extra tip. The calculator will not add tax again, and the tip-base choices change to reflect that the amount you entered already includes tax.
