Explore a household split Get FairTally for your householdFair, not just equal
An equal bill can take a very different share of each person's paycheck. FairTally lets you choose a split around your incomes, responsibilities, or an agreement of your own. Set the ratio once and apply it to shared expenses. These illustrative households show three ways to start the conversation.
Equal split
50 / 50
Alex and Sam earn about the same, so rent, groceries, and streaming get split right down the middle. When things really are equal, 50/50 is fair, and FairTally makes it effortless.
Income-based split
65 / 35
Priya earns nearly twice what Jordan does. An even split would eat a much bigger share of Jordan's paycheck, so they split in proportion to income. Same sacrifice, not same dollars.
Custom weighted split
40 / 35 / 25
Maya, Ren, and Cole share a home as a polycule. Ren travels for work half the year and Cole carries most of the caregiving, so they set their own weights and adjust them when life changes.

Love has evolved. Your financial tools should too.
Sharing a home doesn't mean earning the same amount or contributing in the same way. Money conversations become easier when everyone can see the agreement, the expenses, and the balance.
We built FairTally because we believe every partnership deserves a financial system that reflects how it actually works. One where fairness is defined by the people in the relationship, not by a rigid formula. Where logging an expense feels as natural as splitting the check at dinner.
Whether you're a couple splitting rent and groceries for the first time or a polycule coordinating a shared household budget, FairTally is the financial layer your relationship deserves.
