Rent vs buy calculator

Enter a home price, rent, mortgage terms, and carrying costs. The calculator puts the same starting cash and monthly housing budget on both paths: renters invest the down payment, closing costs, and any monthly gap when owning costs more. Net worth at the horizon is liquid investments for rent, home equity for buy.

Renting leads at the horizon

Renting and investing the difference leads by 5,578 at 7 years under these assumptions.

What each path assumes

Both paths start with enough cash for the down payment and buyer closing costs. The renter invests that pool and adds the monthly difference whenever all-in ownership costs exceed rent. The buyer deploys the cash into equity and pays principal, interest, property tax, insurance, and maintenance.

Home appreciation and investment returns compound monthly. Rent grows once per year at the rate you enter. The model does not include tax deductions, transaction costs when you sell, HOA fees, or mortgage insurance.

Rent net worth = invested down payment + closing costs + monthly investable surplus, compounded. Buy net worth = home value − remaining loan.

Common questions

Why can breakeven be later than I expect?

Closing costs and early-year interest are front-loaded. A low appreciation rate or high maintenance share also pushes the buy path back.
