The formulas
- Owning = down payment + payments + tax, upkeep and insurance - (sale price x (1 - selling cost) - loan balance) + down payment opportunity cost
- Renting = sum of rent with yearly increases
- Advantage = renting - owning
How it works
Owning has a cash cost every year and a payoff at sale. This tool adds the down payment, the mortgage payments, property tax, maintenance and insurance, then subtracts what you keep when you sell after selling costs and paying off the loan. It also charges the return your down payment could have earned elsewhere.
Renting costs the rent you pay as it rises. The result depends mostly on how long you stay and how fast prices rise. It leaves out income tax effects, closing costs on the purchase, and the return on monthly cash that renting leaves free. Run several holding periods before deciding.

Selling costs and the early years of mostly-interest payments take time to recover.
Does the tool include mortgage interest deduction?
No. Taxes are left out.
What property tax rate do I use?
Use the effective rate from your local tax bill.
