Home/Mortgages/Rent vs Buy Calculator

Should I rent or buy a home?

Compare the true cost of renting versus buying over time. See which option builds more wealth based on your specific situation.

What This Calculator Is

A rent versus buy calculator performs a comprehensive financial comparison between continuing to rent and purchasing a home over a specific time period. It accounts for factors often overlooked: home appreciation, equity building, rent increases, opportunity cost of your down payment, and the tax implications of each choice. The result shows which option builds more wealth for your specific situation.

Who This Calculator Is For

Renters considering homeownership who want objective analysis rather than emotional decisions, homeowners wondering if selling and renting makes sense, and anyone relocating to a new area trying to decide their housing strategy. Financial advisors use it to guide clients through one of life's biggest financial decisions.

When to Use This Calculator

Use this calculator when you're unsure whether to buy or continue renting, when considering a move to a new city, when rental markets are particularly expensive or cheap, or when evaluating whether staying in your purchased home makes financial sense. It's especially valuable when you know approximately how long you'll stay in an area, as this dramatically impacts the analysis.

How Rent vs Buy Is Calculated

The calculator factors in all costs of ownership (mortgage, taxes, insurance, maintenance, opportunity cost of down payment) versus renting (rent payments, renter's insurance, potential investment returns on savings). It compares total costs and wealth building over your expected time in the home.

Monthly Mortgage M = L × r(1+r)^n/((1+r)^n−1), L = HomePrice − DownPayment
Year buy cost = 12M + PropertyTax + Insurance(inflated) + PMI(if equity<20%) + HOA + Maintenance(inflated) − TaxBenefit
TaxBenefit = (ItemizedDeductions − StandardDeduction) × TaxRate, if itemized > standard
Year rent cost = 12×Rent + Insurance, Rent grows at RentIncrease% annually
Opportunity cost (rent side) = (DownPayment+ClosingCosts−SecurityDeposit) × (1+InvestReturn)^year
Buy net cost (cumulative) = cumulative buy costs − (HomeValue×(1+appreciation)^year − remaining balance − selling costs)
Rent net cost (cumulative) = cumulative rent costs − opportunity cost − security deposit
Where: r = monthly mortgage rate, n = term×12, PMI = 0.5%×loan/12 removed at 20% equity, standard deduction hardcoded ($14,600 single / $29,200 married-joint, 2024 figures).
Assumptions: Simulated year-by-year over min(YearsToStay,30) years; simple comparison of cumulative costs minus built equity/investment opportunity cost; mortgage interest deduction and SALT cap ($10,000) applied; selling costs % applied only at final-year sale.

Key Takeaways

  • •The longer you stay, the more buying typically makes sense
  • •Don't forget maintenance costs — budget 1-2% of home value annually
  • •Consider the opportunity cost of your down payment if invested elsewhere
  • •Housing markets vary greatly — local conditions matter more than national trends
  • •Factor in lifestyle flexibility — renting offers more mobility
