Rent vs Buy Calculator

The rent vs buy decision is one of the biggest financial choices you'll make. This calculator compares the true total cost of renting (rent + renter's insurance + investment returns on savings) versus buying (mortgage + taxes + insurance + maintenance + closing costs − equity buildup − appreciation − tax benefits) over your chosen timeframe.

What this calculator does

Buying isn't always better than renting. In expensive markets with low appreciation, renting and investing the difference can yield higher net worth. The breakeven point is typically 5-7 years — buying for less than that often loses money due to closing costs and transaction fees.

How it works

The hidden costs of homeownership are substantial: maintenance (1-2% of home value/year), property taxes (0.5-2.5%), insurance, HOA fees, and the opportunity cost of your down payment. A $60,000 down payment invested at 8% grows to

29,000 in 10 years.

Home appreciation averages 3-4% nationally but varies wildly by market. Some areas appreciate 8-10% annually while others stagnate. Don't assume your home will appreciate — it's a risk, not a guarantee.

When to use this calculator

Reach for this tool whenever a financial decision hinges on this type of calculation. Small differences in rate or term become large differences in total cost or return over multi-year horizons — differences that only become visible when you run the actual numbers.

Common mistakes

The most consequential mistake is comparing financial figures that are not on the same basis — gross versus net, before-tax versus after-tax, or nominal versus inflation-adjusted. Always check whether figures you are comparing use the same definition.

Real-world scenarios

A small business owner compares two financing options for new equipment: a 5-year bank loan at 5.2% versus a leasing arrangement with a monthly fee. The calculator translates both into a total cost figure, making the comparison straightforward.

Formula

Rent vs Buy Net Cost Comparison

Net Buy Cost = Purchase Costs + Mortgage Payments + Taxes + Insurance + Maintenance − Equity − Appreciation − Tax Savings

Net Rent Cost = Total Rent Paid + Renter's Insurance − Investment Returns on saved down payment/difference. The lower net cost wins.

Worked example

$400,000 home vs $2,200/month rent, with $80,000 down at 6.5% over 10 years.

  1. Buy total payments: $322,000 (mortgage) + $80,000 (taxes) + $25,000 (insurance) + $40,000 (maintenance) +
    6,000 (closing costs)
  2. Buy equity gained: $67,000 (principal paid) + $80,000 (down payment) + $88,000 (3% appreciation)
  3. Net buy cost: $483,000 − $235,000 equity = $248,000
  4. Rent total: $2,200 × 120 months × 1.03 avg increase = $304,000
  5. Invested down payment ($80k at 7%):
    57,000

Result: Net buy cost: ~$248,000. Net rent cost: ~$304,000 − $77,000 investment gains = ~$227,000. In this case, renting is slightly cheaper over 10 years.

Frequently asked questions

Is it always better to buy than rent?

No. In expensive markets, if you're staying less than 5 years, or if rent is significantly below equivalent mortgage payments, renting and investing the difference can build more wealth.

What is the 5-year rule for buying?

You should plan to stay at least 5-7 years to recoup closing costs (3-6% of purchase price) and transaction costs of selling (6-8%). Buying for less than 5 years usually loses money.

How does the price-to-rent ratio help?

Divide home price by annual rent. Under 15: buying favors. 15-20: borderline. Over 20: renting likely wins. Example: $400,000 ÷ $26,400/year = 15.2 (borderline).
