🍽️ Tip & Bill Split Calculator
← Life & LivingDinner was great. The maths at the end shouldn't be the hard part. Add the bill, choose a tip if you want one, and see exactly what everyone owes. Split it evenly or let people pay for what they actually ordered — right down to the last cent.
Here's what everyone pays
A service charge is money the restaurant adds; a tip is money you choose to add. They are separate lines here, and a 0% tip is a normal result.
Where the total goes
The tip is one piece of the total — not a separate mystery at the end.
Who owes what?
Just one little percentage?
Try another rate without changing the bill. Nothing moves until you apply it.
Want cleaner payment amounts?
The dinner was shared. The bill doesn't have to be awkward.
The plates are cleared, someone's looking for their wallet, and suddenly the easiest part of the evening has become a small accounting exercise. Did the tip get added before or after tax? Does the person who ordered a salad owe the same as the person who ordered three courses? And who gets the leftover cent?
A quick, even split is perfect when everybody's happy to pay the same. When the orders were different, dividing the whole bill by the number of people can leave someone paying for more than they ate. This calculator lets you choose the version that suits your table — without turning dinner into an argument.
You can add an optional tip, account for extra tax or a service charge, and see a real amount for each person. No mysterious rounding. No maths on the back of a receipt. Just the numbers, in front of everyone.
The last cent has main-character energy
🪙 Someone always gets the extra cent
Split a $100 bill three ways and the answer is $33.3333… — not a price anyone can actually send. Two people pay $33.33, one pays $33.34, and the table is square. That one-cent guest always turns up when division won't behave.
🍽️ One extra diner can give everyone a 25% discount
On a fixed $120 bill, three people pay $40 each. Four people pay $30 each. That's 25% less per person just by adding a fourth person to the split. The catch? In real life, extra diners usually order food too.
🧾 A tip on tax really is extra
With $100 of food and $10 of extra tax, a 20% tip on the food is $20. Calculate 20% on the $110 including tax and it's $22. Same meal, same 20% button, $2 difference — all because of the number underneath the percentage.
🥖 The shared starter has a secret price tag
A $12 plate of fries shared by four friends costs $3 each. Share it with just three and it's $4 each. Same fries. The fourth hand reaching for one actually saves the other three a dollar — assuming the plate didn't get bigger.
💸 “Only five more percent” can be surprisingly cheap — or expensive
On a $120 subtotal, a 15% tip is $18 and a 20% tip is $24. The entire table pays $6 extra. With four people splitting equally, that's $1.50 each. The headline percentage sounds bigger than the per-person difference — but it still adds up over repeated meals.
How does this tip and bill split calculator work?
It starts with the amount on the receipt, adds only the extras you enter, and decides what belongs to each diner. The tip is its own line so it never gets confused with a compulsory service charge.
Step 1 — Work out the tip
Tip = selected tip base × tip percentage ÷ 100
- Subtotal only uses the food and drink subtotal.
- Subtotal + tax uses the subtotal and the extra tax amount entered.
- Subtotal + tax + service charge uses all entered charges before the tip.
- A flat-dollar tip uses exactly the entered flat amount instead.
Example: $100 subtotal × 15% = $15 tip. A tip calculated on tax or service charge can be larger, and there is no universal default — your receipt and your preference decide the basis.
Step 2 — Add up the final bill
Grand total = Subtotal + extra tax + service charge + tip
Example: $100 + $8 + $5 + $15 = $128. A fee or tax already included in the subtotal must not be entered a second time, and the currency setting never converts the receipt.
Step 3 — Split the bill
Equal split: the grand total divided by the number of people. $128 ÷ 3 = $42.666…, so the payable amounts become $42.67, $42.67 and $42.66 — not $42.67 three times. The calculator keeps the extra cents and hands them to named people so the total stays exact.
By order: divide shared dishes among the diners who selected them, sum each diner's items, then add tax, service and tip in proportion to that diner's food subtotal. Tiny rounding remainders are assigned carefully so every column and row reconciles exactly.
Worked illustration
| Line on bill | Amount |
|---|---|
| Food and drinks | $100.00 |
| Tax entered separately | $8.00 |
| Service charge entered separately | $5.00 |
| Optional tip, 15% on subtotal | $15.00 |
| Total | $128.00 |
If Person A ordered $72 of the $100 food and Person B ordered $28, their shares including proportionally allocated extras are $92.16 and $35.84.
Assumptions and limitations
- Tips are optional, and tipping customs vary by location and establishment.
- The calculator does not determine local tax rules or whether a receipt already contains tax.
- Some restaurants apply a mandatory service fee; treat it separately from an optional tip. The tool cannot know how a business distributes those funds.
- It assumes all entered food and charge amounts are for one shared bill in one currency.
- Shared items are divided equally among the diners assigned to them; unusual agreements can need manual adjustments.
- Rounding is allocated in whole cents to preserve the actual final bill.
- The calculation is an aid to splitting a receipt, not a legal or tax determination.
Tip & Bill Split Calculator FAQs
How much should I tip?
The calculator doesn't decide that for you. Tipping customs and restaurant policies vary, and a tip isn't appropriate or expected everywhere. Choose 0% if you don't want to add one, pick a percentage, or enter a fixed amount. The tool will simply show what that choice does to the bill.
Should I calculate a tip before or after tax?
It depends on what you're trying to do and the receipt you're looking at. This calculator defaults to tipping on the food and drinks subtotal, but you can switch the basis to include extra tax, or tax and service charge. Check the amounts already included on your receipt so you don't count them twice.
How do you split a restaurant bill evenly?
Add the subtotal and any separately entered tax, service charge and optional tip. Divide that grand total by the number of diners. If the division leaves leftover cents, the calculator distributes them between diners so the actual payments add up to the exact bill total.
Can everybody pay for just what they ordered?
Yes. Switch to Who ordered what?, add the items and select the diners who shared each one. Each person pays for their allocated food and drinks plus their proportion of tax, service charge and optional tip. Shared dishes are divided between the people who actually shared them.
How do we split a tip when everyone ordered different amounts?
In the itemised mode, the tip is allocated in proportion to each person's share of the food and drink subtotal by default. Someone responsible for 30% of the food gets 30% of the tip, subject to one-cent rounding. In an even split, everybody shares the whole bill equally instead.
What if the restaurant has already added a service charge?
Enter the extra service charge only if it hasn't already been included in your entered subtotal. A service charge and an optional tip are displayed separately. You can leave the optional tip at 0%, and you can choose whether the percentage tip is calculated on the subtotal or on a larger base.
Why is one person's payment a cent different?
Money only splits into whole cents. For example, $100 divided by three is $33.333…, so one person pays $33.34 and two pay $33.33. The calculator allocates that spare cent intentionally; otherwise a rounded display could make the group overpay or underpay.
Does changing the currency convert the bill?
No. Currency selection changes the symbol and number formatting, not the exchange rate. If your receipt is in another currency, enter the amount shown in that currency. This calculator is for splitting one bill, not converting between currencies.
Can I round everyone's payment up to the nearest dollar?
The calculator will show that suggestion in the quick split, but it never changes what everyone actually owes. Rounding up collects more than the bill: the extra amount is shown next to it, so the table can decide what happens to it. The exact per-person amounts stay authoritative.
