Same rent, different paychecks. Split by what's actually fair.
An even split can quietly cost more for whoever earns less. Splitting by income keeps rent a similar percentage of everyone's take-home pay instead of a identical dollar figure — enter what each person earns and the rest is automatic.
How an income-based split works
Enter monthly income
Use take-home pay if you want the split to reflect what actually hits your bank account, or gross if your household prefers that.
Rent scales with earnings
Each person's share is proportional to their income — someone earning double pays roughly double, not the same flat amount.
Adjust and compare
Switch to equal or room-size splitting any time to see how the numbers differ before your household agrees on one.
Frequently asked questions
Should rent be split by income or evenly?
Both are common, and it comes down to what your household values. An even split is simplest and treats the apartment as a shared resource regardless of earnings. An income-based split keeps rent proportional to what each person can actually afford, which some roommates or couples prefer, especially when incomes differ significantly.
Gross income or take-home pay?
Either works — the calculator just needs consistent numbers for everyone. Take-home pay tends to produce a split that better reflects actual spending power, since it already accounts for taxes and deductions.
Does this work for couples splitting rent, not just roommates?
Yes — the math is identical whether it's two roommates or two partners. Add both incomes and the calculator does the same proportional split either way.
