Use this free online split bill calculator to divide a shared bill fairly among a group — including tax and tip — while still letting anyone add their own extra items on top of the equal share.
How to Use the Split Bill Calculator
Enter the "Bill Subtotal (₹)", plus any "Tax (%)" and "Tip (%)" to apply.
Add a row for each person, naming them and entering any extra amount they personally ordered (leave blank if none).
Click "Split the Bill" to see exactly how much each person owes, and the grand total.
How Each Share Is Calculated
The calculator separates the bill into two parts: what everyone shared, and what individual people ordered for themselves. Only the shared part is divided equally.
Shared total = Subtotal × (1 + Tax % ÷ 100 + Tip % ÷ 100)
Equal share = Shared total ÷ number of people in the list
Each person owes = Equal share + their own extra amount
Tax and tip are both taken as a percentage of the subtotal and added together. The tip is not calculated on top of the tax, so a 5% tax and 10% tip increase the shared amount by exactly 15%. The grand total at the bottom is the sum of what everyone owes and should match the amount you actually have to pay.
Worked Example
Three colleagues have lunch. The dishes they shared come to ₹3,000, and the bill adds 5% GST. They want to leave a 10% tip. Ravi also ordered a dessert for ₹240 that nobody else had.
Step
Calculation
Amount
Shared total with tax and tip
3,000 × 1.15
₹3,450.00
Equal share for each of 3
3,450 ÷ 3
₹1,150.00
Ravi (with ₹240 extra)
1,150 + 240
₹1,390.00
Each of the other two
1,150 + 0
₹1,150.00
Grand total
1,390 + 1,150 + 1,150
₹3,690.00
Note that the ₹240 dessert must not also be included in the ₹3,000 subtotal. If it were, everyone would be paying a third of it and Ravi would pay for it a second time.
Where This Is Useful
Restaurant and café bills: where most dishes are shared but a few drinks or desserts belong to one person.
Trips with friends: split the hotel, cab or fuel cost equally, and use the extra column for someone who booked a single room or an upgrade.
Flat and PG expenses: divide the electricity, Wi-Fi or cook's salary among flatmates, adding an extra for the person with an air conditioner or a larger room.
Office parties and gifts: collect an equal contribution, with extras for people who added items to the order.
For utility bills and trip costs, simply set Tax and Tip to 0 so that only the subtotal is shared.
Getting the Numbers Right
Check whether the extra items on the bill were taxed. Extras are added at face value, so if a personal item attracted GST, enter its price including GST in the extra field.
If the restaurant has already added a service charge, enter it as part of the tax percentage or leave the tip at 0 so you do not pay twice for service.
Remove anyone who left early or did not eat before calculating, because every name in the list receives an equal share.
Shares are shown to the paisa. When settling over UPI, round up slightly so whoever paid the restaurant is not left short.
Frequently Asked Questions
The bill subtotal is increased by the tax and tip percentages, then divided equally among everyone in the list. Anything entered in a person's "Extra amount" is added on top of their equal share, so shared costs stay fair even when one person ordered something extra.
No — tax and tip are calculated only on the shared bill subtotal. Extra amounts are added afterward at face value, since they are treated as separate personal items.
No. Both the tax and tip percentages are applied to the bill subtotal and added together. With 5% tax and 10% tip on ₹1,000, the shared total is ₹1,150, not ₹1,155.
Yes. Enter the bill as the subtotal, set Tax and Tip to 0, add each flatmate, and use the extra amount field for anyone who should pay more, such as for an air conditioner in their room.
The usual reason is that an extra item has been counted twice, once in the subtotal and again in someone's extra amount. Enter only the shared items as the subtotal. A difference of a few paise can also come from rounding.
