How This Calculator Works

Buying path: Your $90,000 down payment goes into the home. Net worth equals home equity (appreciated value minus remaining loan balance) plus any monthly savings you invest when buying costs less than renting.

Renting path: That same $90,000 is invested in the market on day one. Each month, if buying costs more, the renter invests the difference. As rent increases over time, the renter's monthly surplus shrinks.

With these numbers, one path stays ahead throughout the entire 30-year window. Try adjusting the appreciation rate or investment return to find the crossover.

This model excludes transaction costs (agent commissions, closing costs), capital gains taxes on investments, and the mortgage interest tax deduction. Adjust the appreciation rate, rent increase, and investment return to match your local market.
