Break-Even Analysis
Buying does not break even within your 10-year horizon given these assumptions. Consider extending the comparison period or adjusting appreciation and investment return rates.

Estimates only. All-in buying cost includes mortgage P&I, property tax, insurance, HOA, and maintenance minus estimated mortgage interest tax deduction. Renter net worth assumes monthly savings vs buying are invested at the stated return rate. Actual home appreciation, investment returns, and costs will vary. Consult a licensed financial advisor before making real estate decisions.
The rent-vs-buy decision is one of the most consequential financial choices most Americans will make — and it is rarely as simple as "buying is always better." In 2026, with mortgage rates near 6.8% and home prices elevated in most metros, the break-even timeline has stretched to 7-12 years in many markets. This calculator computes the true all-in cost of buying (mortgage, taxes, insurance, HOA, maintenance, closing costs) against the true cost of renting (including the investment growth you would get by keeping your down payment in the market). It produces the break-even year, year-by-year net worth comparison, and a sensitivity analysis showing how a 1% shift in home appreciation changes the outcome.
Buying path: The calculator amortizes the mortgage month-by-month, tracking the principal/interest split as the balance falls. Each month it adds property tax (% of current home value), insurance, HOA, maintenance (% of current home value), and subtracts the estimated mortgage interest tax deduction (interest × marginal tax rate). The home value compounds at the annual appreciation rate. Net worth = current home value − remaining mortgage balance.
Renting path: The renter starts by investing the down payment plus closing costs (minus security deposit). Each month, the portfolio earns the investment return rate. Any month where buying costs exceed renting costs, the difference is also invested — this models the renter's "savings advantage" during years when renting is cheaper. Net worth = portfolio value.
Break-even: The first year where buying net worth exceeds renting net worth is reported as the break-even year. Before this year, the renter is wealthier; after it, the buyer is wealthier.
Sensitivity: The appreciation ±1% rows show how sensitive your break-even is to home price growth — a key assumption that varies significantly by market and economic cycle.
A couple in Austin deciding whether to buy a $550,000 home with 20% down at 6.8% or continue renting at $2,800/month — they want to know if buying makes financial sense for a 7-year horizon.
A San Francisco renter paying $3,200/month who could buy a comparable condo at $900,000 — the high price-to-rent ratio means they want to model whether the 7% stock market return beats 3.5% appreciation over 10 years.
A first-time buyer comparing a 15-year vs 30-year mortgage — the 15-year has higher monthly payments but builds equity faster, potentially pulling the break-even year earlier.
A financial planner showing a client how a 1% difference in home appreciation (3% vs 4%) shifts the break-even year by 2-3 years, illustrating why local market selection matters.
A relocating professional with a 3-5 year assignment in a new city checking whether it makes sense to buy given the short horizon and 3% closing costs that must be recouped.
Scope note: This calculator uses simplified annual maintenance and tax percentages; actual costs vary by property age, local tax assessment practices, and market. The mortgage interest deduction estimate is a rough percentage-based approximation — actual deductibility depends on whether you itemize, the SALT deduction cap ($10,000), and your total mortgage balance. Investment return rates are user-specified and not guaranteed; stock market returns are volatile year-to-year even if the long-run average is ~7%. Home appreciation is modeled as a smooth annual compound; actual prices are cyclical and can decline. Transaction costs of selling a home (5-6% realtor commissions, closing costs) are not included in the buying cost — add these to compare "selling at Year X" scenarios. PMI is not separately modeled. Always consult a licensed real estate agent and financial advisor before making a home purchase decision.
