Bill splitter
Split a shared bill proportionally by what each person ordered.
The bill splitter takes each person's own subtotal, then splits the shared tax and tip proportionally by each person's share of the total — so someone who ordered more pays a proportionally larger part of the shared tax and tip too, rather than everyone paying an identical extra amount.
How to use
- Add a row per person with their own subtotal (what they actually ordered).
- Enter the tax and tip percentages that apply to the whole table.
- Tax and tip are split proportionally by each person's share of the total subtotal, not split evenly — someone who ordered more pays a proportionally larger share of tax and tip too.
Common use scenarios
- Splitting a group meal where people ordered noticeably different amounts.
- Dividing a shared bill fairly when an even split wouldn't feel right.
- Figuring out exactly what each person owes including their share of tax and tip.
- Settling up after a group order with mixed-price items.

How we verify Bill splitter
How to confirm the proportional split is calculated the way you expect.
Tax and tip are split by each person's share of the subtotal, not evenly
Each person's share of the shared tax and tip equals their own subtotal divided by everyone's combined subtotal — someone who ordered twice as much as another person pays roughly twice as much of the shared tax and tip too.
This assumes tax and tip apply to the combined subtotal
The tax and tip percentages are applied to the sum of everyone's subtotals, then distributed proportionally — this matches how a restaurant bill typically calculates tax and a service charge on the whole table's total.
A row with no subtotal contributes nothing and owes nothing extra
If someone's subtotal is 0 or left blank, their share of the shared costs is 0 — they'd only owe their own (zero) subtotal, which is a reasonable outcome if they genuinely didn't order anything.
Before you rely on the result
- Every person's subtotal reflects what they actually ordered, not an even guess.
- The tax and tip percentages match what the actual bill charges.
- You understand shares are proportional to subtotal, not split evenly across people.
- You've checked that the row totals add up to what the whole table actually owes.
Who this is for
- Anyone splitting a group meal where people ordered different amounts.
- Groups wanting to divide a bill fairly rather than evenly.
- People figuring out exactly what each person owes including tax and tip.
- Anyone settling up after a group order with mixed-price items.
Real-world examples
Group dinner with mixed orders
A group where some people ordered appetizers and drinks while others had just an entrée enters each person's subtotal to split the bill fairly by what they actually consumed.
Office lunch order
Someone collecting money for a shared office lunch order enters each colleague's item cost to figure out exactly what each person should pay, including their share of delivery tax.
Splitting a big celebration bill
A large group celebrating together, with a wide range of what people ordered, uses the tool to divide the final bill (with tax and a service charge) fairly rather than equally.
Limitations
- Rows with a blank or zero subtotal are treated as owing nothing beyond their own subtotal share, which is zero.
Frequently asked questions
Is this the same as splitting the bill evenly?
No — this deliberately splits tax and tip proportionally based on each person's own subtotal, so someone who ordered more pays a proportionally larger share of the shared costs. Use the tip calculator instead if you actually want an even split.
What happens if I leave someone's subtotal at 0?
Their share of the shared tax and tip becomes 0 too, so they'd only owe 0 — reasonable if they truly didn't order anything, but double-check that's intentional.
Are tax and tip calculated on each person's subtotal separately?
No — they're calculated on everyone's combined subtotal first, then distributed proportionally to each person, matching how a restaurant typically taxes the whole table's total.
Do the individual totals add up to the full bill?
They should — since tax and tip are calculated on the combined subtotal and then distributed proportionally, the sum of everyone's total should match the subtotal plus the full tax and tip amount.
