Money Guides

Honest math for the money decisions you actually face

What you'll find here

SplitGenius publishes opinionated money guides covering rent affordability, fair splitting, retirement timing, debt-vs-invest, and life-event budgets. Each guide ships with a free calculator, real 2026 data from HUD, BLS, and Census, and the honest math behind the rule of thumb — not the rule of thumb itself.

Rent & Housing

Honest math on rent affordability, splitting, and the rent-vs-buy decision — by income, city, and life stage.

Fair Splitting

Methods for splitting rent, bills, tips, trips, and shared expenses fairly when nothing is equal.
