Wealth Trajectory (estimated)

Higher is better. This chart converts the “net cost” table into an estimated net position over time (wealth = −net cost).

Disclaimer: This calculator provides estimates for educational purposes only. Actual outcomes depend on market conditions, tax laws, individual circumstances, and many factors that cannot be predicted. Consult a financial advisor before making a buy vs. rent decision.

How This Calculator Works

Most rent vs. buy comparisons only look at monthly payment vs. monthly rent. This calculator accounts for all the costs that matter: the opportunity cost of your down payment (what it would earn invested instead), home appreciation, annual rent increases, tax deductions, maintenance, and selling costs.

What "Total Cost to Buy" Includes

Mortgage P&I, property taxes, home insurance, HOA, maintenance costs — minus equity built from principal paydown and appreciation, minus the mortgage interest deduction if you itemize. On sale, net proceeds (home value minus remaining mortgage minus selling costs) are credited back.

What "Total Cost to Rent" Includes

Monthly rent (increasing each year), renter's insurance, plus the opportunity cost forfeited — what your down payment would have grown to if invested in the market instead. This is the most commonly ignored factor in rent vs. buy comparisons.

The Break-Even Year

The year in which buying becomes cheaper than renting on a cumulative basis. Before this point, renting has the lower total cost; after it, buying does. The calculation assumes you sell at the end of the analysis period.

Key insight: In high-cost markets (San Francisco, New York, Seattle), the break-even is often 8–12 years. In mid-cost markets (Atlanta, Phoenix, Dallas), it's often 3–5 years. The appreciation rate assumption is the biggest variable — be conservative.

Frequently Asked Questions

No. Buying is better when you plan to stay long enough to recoup the upfront costs, when the price-to-rent ratio in your market favors buying, and when your finances support ownership costs. Renting is better when you need flexibility, when housing prices are very high relative to rents, or when you would otherwise invest the down payment in higher-returning assets.
The price-to-rent ratio is the home's purchase price divided by annual rent. A ratio under 15 typically favors buying; 15–20 is neutral; above 20 often favors renting. In NYC and San Francisco, ratios often exceed 30 — meaning you'd pay 30 years' worth of rent just to buy the property, before any costs.
Not necessarily. Homeowners also "throw away" money on mortgage interest (the majority of early payments), property taxes, insurance, and maintenance — none of which build equity. The difference is appreciation and forced savings through principal paydown. In markets with modest appreciation and high price-to-rent ratios, renting and investing the difference can produce better wealth outcomes.
Select your tax bracket in the calculator. The deduction only applies if you itemize (vs. taking the standard deduction). For most buyers, especially with smaller loans, the standard deduction ($14,600 single / $29,200 married for 2024) exceeds itemized deductions, so the actual tax benefit is often $0. Select "0% — Don't itemize" unless you're confident you'll itemize.
