About the Rent vs Buy calculator

A free rent vs buy calculator. Compare the wealth outcome of buying a home versus renting an equivalent property over a fixed holding period. Models down payment, mortgage P&I, property tax, maintenance, home appreciation, selling costs, rent growth and the opportunity cost of investing the down payment. Returns the break-even year and the final wealth gap.

How it works

  1. 1
    Enter the home you'd buy
    Set the home price, your down payment, mortgage rate and term. The calculator computes the monthly P&I, ongoing tax and maintenance, and tracks how equity builds as you amortize the loan.
  2. 2
    Set your holding period
    How many years will you actually live there before selling? This is the single most important input — buying almost always loses on a 1–3 year horizon and almost always wins on a 10+ year horizon.
  3. 3
    Enter the equivalent rent
    What would it cost to rent the same place today? Use the realistic monthly rent, not a number you'd love to pay. Set a sensible annual rent increase (3–5% is typical; HCOL cities run higher).
  4. 4
    Set the opportunity cost
    If you rented instead, you'd invest the down payment and any monthly savings. Use 6–8% for a long-term diversified portfolio; lower if you're conservative. This is where the renter's wealth comes from — without it, buying always looks better than it really is.
  5. 5
    Read the verdict
    The headline shows total wealth gap at the end of your holding period. The break-even pill tells you the earliest year buying overtakes renting on the wealth curve. The breakdown shows the two final wealth bars side by side.

Frequently asked questions

  • Both paths start with the same wealth. The renter invests the down payment up front. Each month, whichever party has the lower monthly outflow invests the surplus at your chosen investment return. At the end of the holding period, the buyer cashes out the home (minus selling costs and any remaining mortgage) and the renter has their investment account. The wealth difference is the answer.

  • The earliest year at which the buyer's total wealth (sale proceeds + side investments) catches up to the renter's investment account. Before that year, renting+investing leaves you wealthier; after it, buying does. Most US scenarios break even between year 5 and year 9 depending on rates, appreciation and rent growth.

  • Because the down payment plus closing costs are real money invested in the home, not earning a market return. The renter puts that same money into a portfolio earning 6–8%. The buyer needs years of appreciation and amortization to overtake the renter's head start — that's the break-even.

  • No. Most US taxpayers no longer itemize under the post-2018 standard deduction, so the mortgage interest deduction provides little or no benefit. Add 0.3–0.5% to your effective appreciation rate if you're confident you'll itemize on a high-rate jumbo loan.

  • Closing costs and points are typically 2–5% of the loan; bake them in by adding to maintenance % or raising the down payment to reflect cash out at purchase. PMI applies if down payment is below 20% — add 0.5–1% to maintenance to approximate it. HOA fees fold into the maintenance % too.

  • Long-run US home prices roughly track inflation plus 1% (so ~3–4% nominal). Specific metros vary widely: Sun Belt cities have averaged 5–7% over the past decade, while parts of the Midwest have been closer to 2%. Use Case-Shiller or Zillow Home Value Index for your area.

  • Same core method (down-payment opportunity cost + monthly surplus invested + sale at exit). The NYT calculator adds more US-specific tax knobs (capital gains exclusion, MID, SALT cap) and a buy-cost-equivalent monthly rent solver. This calculator stays country-agnostic so it works for both US and India.
