Our comprehensive split bill calculator handles every bill-sharing scenario. Split the check evenly among any number of people, divide by custom amounts or percentages, handle tip and tax separately, and round amounts for easy payment. Perfect for restaurants, group trips, shared households, and any expense that needs fair division.
20% tip: Move decimal left ($12), double it = $24
Input the total bill amount (subtotal before tip).
Choose how many people are splitting the bill.
Select tip percentage or enter custom amount.
View what each person owes instantly.
For even splits, add all charges together and divide by the number of people. For uneven splits, assign items or percentages to each person and calculate their share of tip and tax proportionally.
Per Person = (Bill + Tip + Tax) / Number of People
For even splits, simply divide the total by number of people
When splitting unevenly, consider having each person pay for their items plus proportional tip
Round up slightly to avoid awkward change and cover any shortfall
Use Venmo, Zelle, or PayPal to settle up easily after calculating
For recurring shared expenses (rent, utilities), set up automatic tracking
Consider who ordered alcohol vs non-alcoholic drinks when splitting fairly
For large groups, one person can pay the full bill and collect from others
Our free split bill calculator makes dividing expenses easy. Whether you're splitting a restaurant check evenly among friends, dividing a group trip's costs, or calculating custom shares, get exact amounts instantly. Includes tip, tax, and rounding options.
Split your restaurant bill fairly among any number of diners. Add tip percentage, include tax, and see exactly what each person owes. Our restaurant bill split calculator handles everything from casual dinners to large group celebrations.
Calculate each person's share including tip automatically. Choose from standard tip percentages (15%, 18%, 20%, 25%) and see the tip divided equally or proportionally. Our split bill with tip calculator makes tipping fair and easy.
Not everyone ordered the same thing? Our uneven split calculator lets you enter custom amounts for each person. Calculate proportional tip and tax shares based on what each person actually ordered.
Beyond restaurants, split any shared expense: rent, utilities, group trips, shared subscriptions, or event costs. Our group bill calculator works for any situation where costs need fair division among multiple people.
A split bill calculator adds every charge on the check, then divides the total by the number of people paying. The core formula is simple: (Bill + Tip + Tax) ÷ Number of People = each person's share.
The key is deciding what goes into the total before you divide. Tip is normally figured on the pre-tax subtotal, while sales tax is added by the venue at a rate set by your state or city.
The calculator handles two split styles:
Because the math is a fixed formula, results are exact to the cent. According to the Consumer Financial Protection Bureau (CFPB), tracking shared costs this precisely helps groups avoid the small disputes that erode budgets and friendships over time.
Start by entering the subtotal, the number of people, and the tip percentage, then read each person's share from the result. Here is a full worked example.
Suppose four friends have a $120 subtotal, add a 20% tip, and pay $10 in sales tax.
Enter those values and the calculator returns $38.50 each, plus a breakdown showing tip per person ($6) and tax per person ($2.50).
To split unevenly, switch Split Type to custom and type each person's food total, such as 40,30,25,25. The tool then spreads tip and tax by each share's percentage of the subtotal, so a bigger order carries a bigger slice of the extras.
The fairest method calculates tip on the pre-tax subtotal and never tips on the sales tax. Tax is a fixed government charge, so adding gratuity on top of it quietly inflates what everyone pays.
For mixed orders, apply the same percentage logic to both extras:
Remember that tips are taxable income for servers. The Internal Revenue Service (IRS) requires employees to report tip income, and many restaurants add an automatic gratuity for large parties. Check the receipt before adding more, and note that sales-tax rates vary by jurisdiction, so the tax line on your bill reflects local rules rather than a national figure.
The most common mistake is tipping on the post-tax total instead of the subtotal, which overcharges the whole table. A few careful checks keep every split fair.
Watch for these frequent errors:
The Consumer Financial Protection Bureau (CFPB) encourages clear, upfront communication about money, and the Emily Post Institute notes that agreeing on the method before ordering prevents awkwardness when the check arrives.
For recurring household costs, divide each bill by the number of housemates, or weight shares by room size or income when that is fairer. The same split formula applies whether the expense is dinner or the electric bill.
Common approaches include:
Set a fixed monthly due date and one collection point so nothing slips. The Consumer Financial Protection Bureau (CFPB) recommends building shared expenses into a written household budget so everyone sees the same numbers. Prices for essentials shift over time; the U.S. Bureau of Labor Statistics (BLS) tracks these changes through the Consumer Price Index, so revisit your split whenever rent or utility rates rise.
Split evenly when orders are similar and by items when they differ significantly. An even split is faster and signals generosity among close friends, while an itemized split protects people who ordered less.
Use an even split when:
Use an itemized split when:
The Emily Post Institute advises deciding the method openly, ideally before ordering. Whichever you choose, the calculator's custom mode lets you enter exact amounts so each person pays their true share of the subtotal, tip, and tax.
The easiest way to settle is for one person to pay the full check, then have everyone send their share through a payment app. This avoids fumbling with cash and multiple cards at the table.
A simple settlement workflow:
The Consumer Financial Protection Bureau (CFPB) cautions that peer-to-peer transfers are usually instant and hard to reverse, so double-check the recipient and amount before sending. For group trips, keep a running tally of shared costs and settle once at the end rather than transaction by transaction, which cuts fees and confusion while giving everyone a clear final number.
