Rent vs Buy Calculator

Is renting or buying the smarter financial move? This tool factors in home appreciation, rent inflation, property taxes, closing costs, and investment returns to find your breakeven year.

Lower is better. Includes sunk costs minus asset appreciation or investment growth.

How to Use This Calculator

Adjust the buy-side and rent-side parameters to match your situation. The chart updates automatically to show two cumulative cost curves — the point where they cross is your breakeven year.

  1. 1
    Set the Buy-Side Parameters — Enter the home price, down payment, interest rate, property tax rate, and maintenance assumptions for the purchase scenario.
  2. 2
    Set the Rent-Side Parameters — Enter your current monthly rent and expected annual rent increase. Rents typically rise 2-4% per year.
  3. 3
    Adjust Investment Return — Set the expected annual return on the money you'd keep invested if you don't buy (down payment + monthly savings). Default is 7%.
  4. 4
    Find Your Breakeven Year — Look at the chart where the red line (buying) and blue line (renting) cross. That's the year buying becomes cheaper.

📊 Example: $400,000 Home vs $2,000/Month Rent

You're deciding between buying a $400,000 home (20% down, 6.5% rate, 30-year fixed) or continuing to rent at $2,000/month. With 3% appreciation, 3% rent inflation, and 7% investment returns on the opportunity cost:

Buy: Monthly Payment (PITI)$2,547/mo
Rent: Monthly Rent$2,000/mo
Down Payment (Opportunity Cost)$80,000
Breakeven YearYear 4
Net Worth After 10 Years (Buy)+$156,000
Net Worth After 10 Years (Rent)+$134,000

The breakeven comes at year 4 — meaning if you plan to stay 4+ years, buying wins financially. But if you might move in 2-3 years, renting is the safer bet given the high transaction costs of buying and selling.

Understanding Your Results

The rent vs buy decision is about more than just monthly costs. Here's what the key metrics in your results mean:

Breakeven YearThe year when cumulative buying costs equal cumulative renting costs. Before this point, renting is cheaper. After it, buying becomes more affordable over time due to home equity growth and fixed mortgage payments vs rising rents.
Opportunity CostThe investment returns you give up by using your down payment (and monthly savings) for a home instead of investing them in stocks or bonds. At 7% average returns, $80K grows to ~$157K in 10 years — that's the "cost" of using that money for a down payment.
Home EquityAs you pay down your mortgage and your home appreciates, you build equity. After 10 years with 3% appreciation, a $400K home would be worth ~$538K, and you'd have ~$178K in equity from appreciation plus principal paydown on your loan.
Total Cost ComparisonThe chart shows two cumulative cost curves. The buying curve includes down payment, closing costs, PITI, and maintenance. The renting curve includes all rent payments. The gap between them at any point tells you the financial advantage of one option over the other.

Common Mistakes to Avoid

The rent vs buy decision is often clouded by emotion and common misconceptions. Watch out for these:

❌ Assuming buying is always better because "renting is throwing money away."

✅ A $400K home with 20% down at 6.5% costs $2,547/mo in PITI — but only ~$500/mo goes to principal in year one. The rest goes to interest, taxes, and insurance, which is also "throwing money away." Renting is not a bad financial decision if you stay fewer than 4 years.

❌ Ignoring maintenance and repair costs in the buying scenario.

✅ Homeownership comes with 1–2% of home value in annual maintenance. On a $400K home, that's $4K–$8K/year for roof repairs, HVAC, plumbing, and general upkeep. Renters don't pay these costs. Always factor maintenance into your buy vs rent analysis.

❌ Not considering lifestyle flexibility when making the decision.

✅ Renting offers flexibility to move for jobs, relationships, or lifestyle changes without paying 6% in realtor commissions. If your career is unstable or you might relocate, the flexibility of renting has real financial value that goes beyond the breakeven calculation.

Frequently Asked Questions

How do you calculate the breakeven year?
The breakeven year is when the cumulative cost of buying (down payment, closing costs, monthly payments, taxes, insurance, maintenance) intersects with the cumulative cost of renting. Before this point, renting is cheaper; after, buying becomes the better financial choice.
Does the calculator consider investment returns?
Yes. The rent vs buy analysis assumes your down payment and the difference between rent and mortgage payments could be invested in the stock market. We use a default 7% annual return (historical average) to calculate the opportunity cost.
What is home appreciation rate?
Home appreciation is the annual increase in your home's value. Historically, US home prices have appreciated about 3-5% annually on average. We default to 3% for a conservative estimate, but you can adjust this.
How long should I plan to stay in a home for buying to make sense?
Generally, you need to stay in a home for at least 3-5 years for buying to be financially worthwhile. This is due to the high transaction costs (closing costs, realtor fees) that are incurred when buying and selling. Use the calculator to find your exact breakeven year.
