What Is a Rent vs Buy Calculator?

A rent vs buy calculator compares the total cost of renting against buying over a specific time horizon, accounting for mortgage payments, property taxes, maintenance, opportunity cost of the down payment, rent increases, and home appreciation. The answer is not always "buying builds equity" — in many markets and situations, renting and investing the difference produces better financial outcomes, especially for stays under 5 years.1

The True Cost of Buying

Buyers pay more than the mortgage: closing costs (2–5% upfront), property taxes (0.5–2.5%/year), insurance ($100–250/month), maintenance (1–2% of value/year), and opportunity cost on the down payment. On a $400K home with 20% down, the first-year non-mortgage costs alone total roughly $12,000–$20,000. These "hidden" costs mean buying is often more expensive than renting in the short term.2

The Break-Even Timeline

Buying generally becomes financially favorable after 5–7 years, once closing costs are recouped and equity accumulation outpaces the opportunity cost of the down payment. In high-cost markets with low appreciation, the break-even can stretch to 10+ years. In rapidly appreciating markets, it can be as short as 2–3 years. The key variables: local price-to-rent ratio, expected appreciation, mortgage rate, and how long you'll stay. Use our Mortgage Calculator to model different scenarios.3

The Price-to-Rent Ratio

Divide the home price by annual rent to get the price-to-rent ratio. Below 15: buying is usually favorable. Between 15–20: it's roughly neutral. Above 20: renting and investing the difference is likely better. In 2024–2025, many coastal metros have ratios above 25, making renting the stronger financial choice for stays under 7–10 years. Midwest and Sun Belt cities often have ratios under 15, where buying wins earlier.4

The True Cost of Renting vs. Buying

The rent-versus-buy decision involves far more variables than simply comparing monthly rent to a mortgage payment. Buying includes costs that renters never face: property taxes (averaging 1–2% of home value annually), homeowners insurance ($1,200–$3,000 per year), maintenance and repairs (budget 1–2% of home value annually), mortgage interest, closing costs (2–5% at purchase), and opportunity cost on the down payment. Renting includes costs that buyers avoid: annual rent increases (typically 3–5%), renter's insurance ($15–$30 per month), and the inability to build equity. A meaningful comparison must account for all these factors over the expected time horizon. This calculator performs that full analysis, revealing the financial break-even point where buying becomes advantageous — and many people are surprised to learn it often takes 5–7 years of ownership before buying pulls ahead of renting the same quality home.

Monthly Cost Comparison: Buying vs. Renting

Cost ComponentRenting ($2,000/mo)Buying ($400K home)
Monthly payment$2,000 rent$2,100 mortgage (P&I)
Property tax$0$400/mo (1.2%)
Insurance$20 renter's$150 homeowner's
Maintenance$0$333/mo (1% of value)
PMI (if <20% down)$0$100–$200/mo
Total monthly outflow$2,020$2,983–$3,183

At first glance, buying appears significantly more expensive. But this comparison misses the equity component — a portion of each mortgage payment reduces principal, building ownership stake. After 5 years of a 30-year mortgage on a $400,000 home, roughly $40,000 of mortgage payments have gone toward principal — money that becomes yours when you sell. The renter, meanwhile, has built zero equity. The question is whether the renter could have invested the monthly savings (the difference between renting and buying costs) and earned more than the homeowner gained through equity and appreciation.

The Opportunity Cost of a Down Payment

A 20% down payment on a $400,000 home is $80,000 — money that could otherwise be invested in a diversified portfolio. At a historical average stock market return of 10% annually, $80,000 invested for 10 years grows to approximately $207,000. Meanwhile, $80,000 in home equity on a home appreciating at 3.5% annually becomes roughly $113,000 in equity from appreciation alone (plus principal paydown). The stock market investment outperforms in this scenario — but the homeowner gains leverage: that $80,000 down payment controls a $400,000 asset, so 3.5% appreciation on $400,000 yields $14,000 per year in home value growth on an $80,000 investment, which is effectively a 17.5% return on the down payment. This leverage effect is the primary reason homeownership has historically been the largest wealth-building vehicle for middle-class families. Use our Down Payment Calculator to model different down payment scenarios.

Break-Even Timeline by Market

ScenarioHome PriceMonthly RentAppreciationBreak-Even (Years)
Low-cost market$250,000$1,2003%3–4 years
Average market$400,000$2,0003.5%5–6 years
High-cost market$750,000$3,0004%6–8 years
Very high-cost (SF, NYC)$1,200,000$4,0004%8–12 years

Break-even is the number of years you must own before buying becomes cheaper than renting on a total-cost basis. In expensive markets where the price-to-rent ratio is high, the break-even period extends significantly. If you expect to move within the break-even window, renting is almost always the better financial choice — selling costs (5–6% agent commissions plus closing costs) consume equity gains in short holding periods. The price-to-rent ratio (home price divided by annual rent) provides a quick benchmark: ratios below 15 favor buying, 15–20 are neutral, and above 20 favor renting.

Tax Benefits of Homeownership

Homeowners can deduct mortgage interest on up to $750,000 of acquisition debt and up to $10,000 in state and local taxes (including property taxes) — but only if they itemize deductions. Since the standard deduction ($30,000 for joint filers) exceeds most homeowners' total itemized deductions, the mortgage interest deduction provides no benefit to the roughly 90% of households that take the standard deduction. The deduction primarily benefits higher-income homeowners with large mortgages and high state taxes. The capital gains exclusion is more universally valuable: when you sell a primary residence after living in it for at least 2 of the past 5 years, up to $250,000 in gains ($500,000 for married couples) is completely tax-free. On a home purchased for $400,000 and sold for $650,000, the entire $250,000 gain is excluded — a significant tax advantage unavailable to stock investors. See our Mortgage Calculator for detailed payment breakdowns and our Closing Cost Calculator to estimate purchase transaction costs.

Hidden Costs That Shift the Equation

Several costs consistently surprise first-time homebuyers. HOA fees ($200–$800+ per month for condos and planned communities) are a recurring expense that provides no equity benefit. Major system replacements — roof ($8,000–$25,000), HVAC ($5,000–$15,000), water heater ($1,000–$3,000), appliances ($3,000–$10,000) — occur unpredictably and are entirely the owner's responsibility. The renovation trap consumes many homeowners' budgets: the national average kitchen remodel costs $25,000–$75,000 and typically recoups only 60–80% of the investment at sale. Time is also a real cost — homeowners spend an average of 10–15 hours per month on maintenance, yard work, and repairs that renters delegate to a landlord. When quantifying the rent-vs-buy decision, include a realistic maintenance budget (not just the theoretical 1–2% rule) and your personal value of time spent on home upkeep.

Building Equity vs. Investing the Difference

The core financial comparison is whether the equity built through homeownership exceeds the investment returns a renter could achieve by investing the monthly cost savings. A renter saving $1,000 per month compared to the total cost of owning, invested in a diversified portfolio averaging 8% annually, accumulates approximately $182,000 over 10 years. The homeowner, meanwhile, builds equity through principal paydown (roughly $50,000 over 10 years on a $400,000 mortgage) plus appreciation (approximately $160,000 at 3.5% annual growth) — totaling $210,000 in equity gains. In this scenario, buying wins over 10 years. But at 5 years, the renter-investor may be ahead because closing costs and early mortgage amortization (which is heavily weighted toward interest) slow the homeowner's equity growth. The time horizon is the decisive variable in nearly every rent-versus-buy analysis, which is why our calculator models multiple holding periods. See our Investment Calculator to model the renter-investor scenario in detail.

Is it always better to buy than rent?
No. Buying is not always financially superior. In high-cost markets, for short stays (under 5 years), or when the price-to-rent ratio exceeds 20, renting and investing the difference often produces better financial outcomes. The right answer depends on your specific market, timeline, and financial situation.
How long do I need to stay for buying to make sense?
Typically 5–7 years to recoup closing costs and transaction fees. In rapidly appreciating markets, as few as 3 years. In flat or high-cost markets, 7–10+ years. If there's a meaningful chance you'll move within 3 years, renting is almost always the safer financial choice.
What is the opportunity cost of a down payment?
An $80,000 down payment invested in index funds at 7% average return would grow to ~$112,000 in 5 years. That $32,000 in foregone gains is the opportunity cost of buying. However, home equity also grows through appreciation and mortgage paydown — the comparison depends on market conditions.
Does building equity make buying always win long-term?
Equity building is real but often overstated. In the first 5 years of a 30-year mortgage, most payments go to interest — you build only about $30,000 in equity on a $320K loan. The renter who invests the down payment and monthly savings can accumulate comparable or greater wealth in many scenarios.
Should I factor in tax benefits of homeownership?
Only if you itemize deductions. After the 2017 tax reform doubled the standard deduction, fewer than 10% of taxpayers itemize. If your mortgage interest plus property taxes plus state income tax total less than the standard deduction ($29,200 for married filers in 2024), you get no additional tax benefit from owning.

How to Use This Calculator

  1. Enter your current rent — Monthly rent including any fees.
  2. Enter the home purchase details — Price, down payment, mortgage rate, property taxes, and insurance.
  3. Set your time horizon — How many years you expect to stay.
  4. Compare total costs — The calculator shows cumulative cost of renting vs buying at each year, including opportunity cost of the down payment.

Tips and Best Practices

Don't ignore transaction costs. Selling a home costs 6–10% (agent commissions + closing costs). On a $400K home, that's $24K–$40K when you sell.

Factor in rent increases. Rent typically rises 3–5% annually. This makes buying look better over longer time horizons as your fixed mortgage stays constant.

Compare at 5, 10, and 15 years. The answer often changes dramatically based on timeline. Short stays favor renting; long stays favor buying.

Invest the difference if renting. The financial case for renting only works if you actually invest the savings. Renting and spending the difference is the worst of both worlds.
