50/50 isn't always fair. Now you have options.
Split expenses by income, percentage, or custom ratio. Are We Even does the math so you can skip the awkward conversation.
This is for you if...
- ✓You and your partner earn different amounts and want to split costs fairly
- ✓Your roommate has the master bedroom and everyone knows the rent should reflect that
- ✓You're tired of pretending equal means fair
- ✓You want a clear system instead of vague agreements
Fair doesn't have a single definition. Your expense-sharing tool should reflect that.
Built for real-world sharing
Are We Even helps people split costs the way they actually want to — not just down the middle. Couples, roommates, co-parents, and friend groups use it to define fairness on their own terms.
No formulas to build.
Just pick a split and move on.
Why uneven splits are hard to manage
The math gets messy fast
60/40 on rent, equal on groceries, 70/30 on the vacation house. Tracking multiple ratios by hand breaks down quickly.
Nobody wants to bring it up
Suggesting an uneven split feels uncomfortable — even when everyone agrees it makes sense.
Spreadsheets can't flex per expense
Most tools assume one split ratio for everything. Real life doesn't work that way.
Payment apps don't do ratios
Venmo lets you request a specific amount. It doesn't help you figure out what that amount should be.
Set the split. Forget the math.
Are We Even lets you assign a different split ratio to every expense. Income-based, percentage-based, or fully custom. The app calculates each person's share automatically. No arguing over numbers. No calculator app on the side. No resentment building in silence.

Frequently Asked Questions
- How does income-based splitting work?
- Each person enters their income. The app calculates proportional percentages — if you earn 60% of the combined income, you pay 60% of shared costs. Income values are used for calculation only and aren't stored or shared.
- Can I use different split methods for different expenses?
- Yes. Rent can be income-based, groceries can be equal, and a weekend trip can be split by custom amounts. Every expense is independent.
- What if our income changes?
- Update the numbers anytime. Future expenses use the new ratio. Past expenses stay as they were — your history remains accurate.
Fair means different things to different people.
Your expense-sharing tool should be flexible enough to handle that.
