Fair Calculator
Split shared costs fairly when an equal split isn't fair
Pick a situation — a shared taxi, a meal, rent, a group stay — add the people and a few details, and see who should pay how much, with a short explanation of why that's fair.
Highlights
- Ten everyday situations: shared rides, meals, food delivery, discounts, shipping, rent, stays, road trips, utilities and rewards.
- Every answer shows who pays how much, and a short, plain explanation of why it's fair.
- It picks the fair way to split for you — there's no formula to learn.
- Everything is worked out on your iPhone. Nothing you type is sent anywhere unless you share a result yourself.
- In 39 languages.
- Free with ads; a small yearly Premium subscription removes them.
