Compare renting vs buying a home over any time period. Model mortgage costs, appreciation, investment returns, and tax benefits to see which builds more wealth.
The rent-vs-buy decision is the most impactful financial choice most people face, and the answer depends on dozens of variables: mortgage rates, home appreciation, investment returns on the money you'd otherwise invest, property taxes, maintenance costs, how long you stay, and your tax bracket. A simple "your mortgage is less than rent" comparison misses most of the picture.
The critical insight most people miss: when you buy, your down payment is locked into the house instead of invested in stocks. A renter who invests $84,000 (what would have been a 20% down payment) at 7% stock market returns grows that to ~$135,000 in 7 years. The buyer needs their home to appreciate enough to beat that — plus cover property taxes, maintenance, insurance, and selling costs that the renter doesn't pay.
This calculator models both paths simultaneously: the buyer accumulates equity through appreciation and principal paydown, while the renter invests the down payment plus any monthly savings (if buying costs more). After the specified time period, it compares total wealth: the buyer's home equity minus selling costs vs the renter's investment portfolio. The year-by-year comparison shows when (and if) buying overtakes renting.
A lower monthly mortgage payment does not automatically mean buying is the stronger financial move. This calculator compares the full housing decision, including opportunity cost of the down payment, maintenance, taxes, selling costs, and renter investing assumptions, so you can see which path actually builds more wealth over your expected time horizon.
Buyer Wealth = Home Value × (1 + Appreciation)^Years − Selling Costs − Remaining Mortgage Renter Wealth = Down Payment × (1 + InvReturn)^Years + Invested Monthly Savings Monthly Buying Cost = Mortgage P&I + Property Tax + Insurance + Maintenance Renter Monthly Savings = Buying Cost − Rent (invested if positive) Verdict: Compare Buyer Wealth vs Renter Wealth after N years
Result: Buying wins by $42,000 — Buyer wealth $198K vs Renter wealth $156K
Over 7 years: home appreciates to ~$533K. After 6% selling costs and remaining mortgage ($310K), buyer equity = ~$198K. Renter invests $84K down payment at 7% + monthly savings → portfolio of ~$156K. Buying wins, but only because of 3.5% appreciation and 7-year hold.
The biggest separator in a rent-versus-buy model is usually time. Buying carries large upfront and exit costs, while the early years of a mortgage are interest-heavy. Even when the monthly payment looks competitive, a short stay can still make buying worse because appreciation has not had enough time to overcome transaction costs.
The result can swing dramatically when you adjust appreciation, investment return, maintenance, or the years you expect to stay in the home. Change one assumption at a time and note which variable flips the verdict. That gives you a better planning view than relying on a single optimistic default case.
The calculator helps with the financial side, but the final decision still includes stability, school districts, freedom to renovate, commute risk, and career flexibility. Use the numbers to understand the tradeoff first, then weigh the lifestyle reasons separately so you know exactly what you are paying for.
No. Buying wins when you hold long enough (usually 5-7+ years), appreciation is decent (3%+), and mortgage rates are reasonable. Renting often wins with: short hold periods (< 5 years), high home prices relative to rent (price-to-rent ratio > 20), high mortgage rates, or if you can invest the difference at high returns.
Typically 5-7 years, but it varies wildly. Transaction costs (6% selling + 2-3% buying = 8-9%) must be recovered through appreciation. At 4% annual appreciation, breaking even on transaction costs alone takes about 2 years. Adding opportunity cost of down payment pushes it to 5-7 years.
Extremely. Changing appreciation from 3% to 5% (or 1%) swings the result by hundreds of thousands over 10+ years. No one can predict appreciation. Use 3-4% for conservative estimates. Use local historical data (Case-Shiller) rather than national averages.
For a fair comparison, the renter's money must go somewhere. If you don't buy, that $84K down payment could be invested in a stock index fund. At 7% average return, it grows significantly. Ignoring this "opportunity cost" makes buying look better than it really is.
It helps, but less than most think. Only the interest above the standard deduction matters (and since 2018, the standard deduction is $14,600 single / $29,200 married). Many homeowners don't itemize at all. This calculator accounts for the deduction at your marginal tax rate.
Property tax (1-2%/year), homeowner's insurance ($1,000-3,000/year), maintenance (1-2%/year), HOA fees, closing costs (2-5%), and selling costs (5-6%). Total hidden costs often add 3-5% of home value annually. Renters pay none of these directly.
