Bill Split Calculator with Tip
Split Any Bill Equally or Unevenly — With Tip — Instantly Free
What is a Bill Split Calculator?
A bill split calculator helps you divide a restaurant bill, dinner tab, or any shared expense fairly among a group of people. Whether you are splitting equally with friends or dividing unevenly because different people ordered different things, this tool does the math instantly — including tip. No more awkward mental arithmetic at the table or arguments about who owes what.
How to Split a Bill with Tip
Splitting a bill with tip involves two steps: first calculating the tip amount on top of the original bill, then dividing the total among the people sharing it. Our calculator handles both steps at once. You can also choose whether everyone splits the tip equally or whether each person's tip is proportional to what they ordered — which is the fairest method when orders vary widely.
Equal Split vs Uneven Split — Which Should You Use?
Equal Split
Equal split is the simplest approach — the total bill (including tip) is divided by the number of people present. It works well when everyone ordered roughly the same amount, or when the group just wants to keep things simple and fast. Enter the total bill, tip percentage, and number of people and you get an instant answer.
Uneven (Custom) Split
Custom split is the fair approach when people ordered very different things — one person had a steak and cocktails, another just had a salad and water. Enter each person's name and the amount they ordered, and the calculator shows exactly what each person owes, including their share of the tip. This avoids the common situation where light eaters end up subsidising heavy spenders.
How is Tip Calculated?
Tip is calculated as a percentage of the pre-tax bill total. Standard tip percentages vary by country and culture. Our calculator lets you enter any percentage, but here are common benchmarks as a reference:
- 10% — minimum tip for basic service in most countries
- 15% — standard tip for good service in the US and Canada
- 18%–20% — standard tip for great service in the US
- 25%+ — exceptional service or special occasions
- 0% — tipping is not customary in Japan, South Korea, and some European countries
How to Split a Bill When People Drank Alcohol and Others Didn't
This is one of the most common and uncomfortable bill-splitting situations. The fairest solution is to use the uneven (custom) split option. Assign each person or subgroup what they actually consumed, then split the tip proportionally or equally. This way, non-drinkers or light eaters are not forced to cover the cost of someone else's alcohol or expensive dishes.
Bill Split Formula
Tip Amount = (Bill Total × Tip%) ÷ 100 Total with Tip = Bill Total + Tip Amount Equal Split: Each Person Pays = Total with Tip ÷ Number of People Custom Split: Person's Tip = (Person's Order ÷ Bill Total) × Tip Amount Person's Total = Person's Order + Person's Tip
Tips for Splitting Bills Fairly in a Group
- Always agree on the splitting method before ordering — saves arguments later
- Use custom split mode when orders vary significantly in price
- Split the tip equally even in custom mode unless someone is a known over-tipper
- Apps like Splitwise are great for tracking bills over multiple outings with the same group
- When in doubt, round up your contribution slightly — no one likes being short-changed on a group bill
- Tax is sometimes added automatically — check if your bill total already includes it before entering
