The standard advice goes something like this: buying builds equity, renting throws money away. But that framing skips over a long list of costs that come with owning a home, and it ignores the investment potential of money you would have spent on a down payment. The truth is more nuanced than any one-liner, and it depends heavily on where you live, how long you plan to stay, and what you would do with your savings if you kept renting.
In most U.S. metros, the monthly mortgage payment on a median-priced home now exceeds the median rent by 30% or more, according to data from the National Association of Realtors. That gap has widened significantly since 2021. So the rent-vs-buy math has shifted, and it is worth running the numbers for your specific situation before committing either way.
This guide walks through every cost on both sides of the equation, shows you how to model the comparison year by year, and points to the tools that make the math manageable.
The Hidden Costs That Make This Comparison Tricky
Most people compare their rent payment to a mortgage payment and stop there. But the real comparison involves at least a dozen variables on each side.

Costs of Buying Most People Undercount
When you buy a home, your monthly housing cost includes principal and interest, property taxes, homeowner's insurance, and possibly private mortgage insurance (PMI) if your down payment is under 20%. On top of that, you are responsible for maintenance and repairs, which the Consumer Financial Protection Bureau suggests budgeting at 1% to 2% of your home's value each year.
Then there are the transaction costs. Closing costs typically run 2% to 5% of the purchase price. When you eventually sell, real estate agent commissions eat another 5% to 6%. These transaction costs are often the reason buying does not pay off for people who move within three to five years.
Costs of Renting Most People Ignore
Renters avoid maintenance, property taxes, and transaction costs. But rent increases compound over time, and in many markets rents climb 3% to 5% per year. Over a decade, that turns a $1,800 monthly rent into $2,400 or more.
The bigger hidden cost of renting is the opportunity that homeowners get to lock in a fixed housing payment (with a fixed-rate mortgage) while building equity through appreciation and principal paydown. However, renters also have an advantage: the money they do not spend on a down payment, closing costs, and repairs can be invested elsewhere.
How to Run a Real Rent vs. Buy Comparison
A meaningful comparison needs to account for the full cost of each option over the same time horizon, then compare net financial outcomes. Here is how to do it step by step.

Step 1: Set Your Time Horizon
This is the single most important variable. If you plan to stay in one place for two years, buying almost never wins because closing costs and selling commissions eat your equity gains. At five years, it depends on local appreciation rates and your mortgage terms. At ten years or longer, buying tends to pull ahead in most markets.
Pick a realistic number. If your job might relocate you in three years, model for three years, not the ten-year scenario that makes the spreadsheet look good.
Step 2: Calculate the Full Monthly Cost of Buying
Start with the mortgage payment. Use the Mortgage Payment Calculator to get your principal and interest based on your loan amount, rate, and term. Then add:
- Property taxes (check your county assessor or use the Property Tax Estimator to model this)
- Homeowner's insurance (typically $100 to $300 per month depending on location and coverage)
- PMI if your down payment is below 20% (usually 0.5% to 1% of the loan amount annually)
- Maintenance budget (1% to 2% of home value per year, divided by 12)
- HOA fees if applicable
For a $350,000 home with 10% down, a 6.5% rate on a 30-year fixed mortgage, you might be looking at $2,000 for P&I, $290 for taxes, $150 for insurance, $130 for PMI, and $290 for maintenance. That is roughly $2,860 per month, not the $2,000 you see on the mortgage calculator alone.
Step 3: Calculate the Full Monthly Cost of Renting
Start with your current rent. Then model annual increases. If your landlord has raised rent 4% annually over the past few years, use that rate. Also factor in renter's insurance, which is typically $15 to $30 per month.
Step 4: Account for Equity Building and Investment Returns
Here is where the comparison gets interesting. As a buyer, a portion of each mortgage payment goes toward principal, building equity. Your home may also appreciate in value. According to the Federal Housing Finance Agency, U.S. home prices have averaged roughly 3.5% to 4% annual appreciation over the long run, though this varies dramatically by region.
As a renter, your down payment money stays invested. If you put $35,000 into an index fund earning 7% annually instead of using it as a down payment, that money grows on its own. The free rent vs buy calculator on EvvyTools handles this side-by-side comparison automatically, factoring in equity buildup on the buying side and investment growth on the renting side over your chosen time horizon.
Step 5: Compare Net Outcomes at the End of Your Time Horizon
After your chosen number of years, what is the financial picture on each side?
For buying: home value minus remaining mortgage balance minus selling costs equals your net proceeds.
For renting: total investment portfolio value minus the cumulative extra rent paid (compared to year one) gives you a sense of where you stand.
The crossover point, where buying starts to win financially, typically lands between five and eight years for most scenarios. But in expensive coastal markets with slow appreciation, it can be much longer.

Five Mistakes That Wreck the Rent vs. Buy Calculation
Ignoring Opportunity Cost of the Down Payment
A $50,000 down payment is not just cash you hand over. It is $50,000 that stops earning investment returns. Over ten years at 7% average returns, that $50,000 would have grown to roughly $98,000. The same logic applies to closing costs and the ongoing maintenance budget. Every dollar you pour into your house is a dollar that is not compounding in a brokerage account. Any honest comparison must include this trade-off on both sides of the ledger.
Using National Averages Instead of Local Data
National median home prices and average rents are meaningless for your decision. A rent-vs-buy analysis for Austin looks completely different from one for Cleveland. Use your actual rent, actual home prices in your target neighborhood, and your state's property tax rate.
Forgetting About Maintenance Costs
New homeowners are consistently surprised by repair bills. A new roof costs $8,000 to $15,000. An HVAC replacement runs $5,000 to $10,000. Even in a good year, you should expect to spend $3,000 to $7,000 on upkeep for an average home, according to Bankrate's analysis of homeownership costs.
Assuming You Will Stay Longer Than You Actually Will
The median tenure for a homeowner is about 13 years, according to the National Association of Realtors. But many first-time buyers move within five to seven years. If you model for 15 years but sell after 4, the transaction costs can wipe out any equity you built.
Treating the Mortgage Payment as the Whole Cost
As shown in Step 2 above, the mortgage payment is just one piece. The actual monthly cost of owning is typically 30% to 50% higher than the P&I payment alone. Property taxes, insurance, PMI, maintenance, and occasional HOA fees all add up. When someone says "my mortgage is only $1,800," the real monthly housing cost might be closer to $2,500 or $2,700 once everything is included. Always compare total housing costs, not just the loan payment.
Tools That Help You Model Both Scenarios
Running this comparison by hand is tedious. These tools make it manageable:
- Rent vs. Buy Calculator - models both scenarios year by year with equity buildup, investment returns, and a visual crossover chart
- Home Affordability Calculator - shows you the maximum home price your income supports before you start comparing
- Closing Cost Calculator - estimates the upfront transaction costs that affect your break-even timeline
- Budget Calculator - helps you see whether either housing option fits within a healthy spending plan
For external perspective on this decision, Investopedia's Renting vs. Buying guide offers a solid overview of the qualitative factors, and the New York Times Rent vs. Buy Calculator is another well-known tool for exploring how the variables interact.

The Right Question Is Not "Which Is Cheaper"
The financial comparison matters, but it is only half the story. Owning a home gives you control over your living space, predictable monthly costs with a fixed-rate mortgage, and a forced savings mechanism through principal paydown. Renting gives you flexibility, lower upfront costs, and freedom from maintenance headaches.
Run the numbers with the Rent vs. Buy Calculator to see where the crossover point falls for your situation. If buying wins financially at year four but you might move at year three, the math is telling you something. Let the data guide the decision, not the conventional wisdom.
