Free bill splitting calculators

Five free calculators for the money questions that come up in every group: how much each person owes on a restaurant bill, who pays whom after a trip, how to split rent between rooms of different sizes, how to collect your share over UPI, and what each person owes for fuel on a road trip. They work on your phone, need no account, and do all the maths in your browser.

Updated November 2026

Bill splitter

Split a restaurant bill with tax and tip. Round each share up, or split unevenly by what each person ordered.

Trip expense calculator

Add people and expenses, then see who owes who and the fewest payments to settle the whole group.

Rent split calculator

Split rent equally, by room size, or weighted for a private bathroom, balcony or parking. Utilities split equally.

UPI split

Split a bill and make a UPI payment link for each friend that opens GPay, PhonePe or Paytm with the amount filled in.

Fuel cost splitter

Road trip petrol and tolls per person from distance and mileage, leg by leg, with or without the driver paying.

Which calculator do I need?

One bill, paid now: use the bill splitter. It handles tax, tip and rounding, and an uneven mode for when one person only had a coffee.
Many expenses, different payers: use the trip expense calculator. It nets everything into one balance per person and lists the fewest payments.
Monthly rent with flatmates: use the rent split calculator to set a fair amount for each room once.
Collecting money in India: use UPI split to send each friend a payment link with their share.
Petrol for a road trip: use the fuel cost splitter. It works out each person's share of fuel and tolls, even when someone rides only part of the way.

Private and free

None of these tools need you to sign in. What you type stays in your browser: the trip calculator saves your list in this browser so a refresh does not lose it, and nothing is sent to SplitSimple. When you want the group to see the same numbers and track who has paid, open the free SplitSimple app and start a group.
