Net Worth Comparison Over Time
Buyer net worth (home equity - costs) vs Renter net worth (invested down payment + savings)
How This Calculator Works
Most rent vs buy calculators only compare monthly payments. This one computes the true total financial outcome of each path over your chosen time horizon, including factors most people overlook.
What's included in the Buying cost
- Mortgage payments (principal + interest over the full period)
- Down payment and closing costs (upfront cash out the door)
- Property taxes (applied to rising home value each year)
- Homeowner insurance
- Maintenance and repairs (1% of home value per year is the standard rule of thumb)
- HOA fees (if applicable)
- PMI (if less than 20% down, until equity reaches 20%)
- Selling costs (agent commissions + closing: ~5--7% of sale price)
- Minus: home equity built (appreciation + principal paydown)
- Minus: mortgage interest tax deduction (if you itemize)
What's included in the Renting cost
- Rent payments (growing at your specified annual rate)
- Renter insurance
- Minus: investment returns on the down payment and closing costs that weren't spent (opportunity cost)
- Minus: investment returns on any monthly savings (if rent is cheaper than the full buying cost)
The opportunity cost most people miss: A $80,000 down payment invested in a diversified index fund at 7% annual return grows to $157,000 in 10 years and $305,000 in 20 years. This "cost" of buying is real money -- the wealth you give up by tying it up in a home instead of the market. The calculator models this carefully.
The Break-Even Point
The break-even year is when buying becomes cheaper than renting on a cumulative basis. Before that point, the renter who invests the difference comes out ahead. After that point, the buyer's equity and price lock-in win. For most US markets, the break-even is 5--10 years -- which is why "don't buy unless you plan to stay 5+ years" is standard financial advice.
Frequently Asked Questions
Is buying always better than renting long-term?
Not necessarily -- it depends on the price-to-rent ratio in your market, how long you stay, your investment discipline as a renter, and local appreciation rates. In expensive markets like San Francisco or NYC, renting and investing the difference can outperform buying even over 20 years. In lower-cost Midwest markets, buying wins faster. The most honest answer is: run the numbers for your specific situation using realistic assumptions, and factor in non-financial benefits of ownership (stability, customization, no landlord) that don't show up in any calculator.
What is the price-to-rent ratio and how do I use it?
The price-to-rent ratio is the home price divided by the annual rent for a comparable property. A ratio under 15 generally favors buying; 15--20 is neutral; above 20 often favors renting. For example: a $400,000 home with comparable rental at $2,000/month = $24,000/year. Ratio = 400,000 / 24,000 = 16.7 -- borderline. Many major US cities have ratios of 25--40+, meaning the math strongly favors renting unless you expect exceptional appreciation or plan to stay a very long time.
Does the mortgage interest tax deduction make buying much better?
Less than most people think, and only if you itemize. Since the 2017 Tax Cuts and Jobs Act nearly doubled the standard deduction, about 90% of taxpayers no longer itemize. If you take the standard deduction, you receive zero tax benefit from mortgage interest. If you do itemize -- typically homeowners with very large mortgages in high-tax states -- the benefit is real but modest: on a $350,000 mortgage at 7%, year-one interest is ~$24,000. If this gets you above the $15,700 standard deduction, only the excess saves you money. At the 22% bracket, the maximum realistic annual tax benefit is a few thousand dollars.
How much should I use for home appreciation?
The long-run US national average is roughly 3--4% per year nominally, which is close to the inflation rate -- meaning real (inflation-adjusted) appreciation is near zero historically. Individual markets vary enormously: coastal metros have averaged 5--7%+ over the past 30 years; some inland markets have been closer to 1--2%. Use 3--3.5% as a conservative baseline unless you have strong local data. Be very cautious about using recent high appreciation rates (2020--2023 saw 15--40% in some markets) -- those were anomalous and mean-revert.
What if I can't afford the down payment to invest anyway?
This is the key real-world nuance. The opportunity cost comparison assumes the renter actually invests the down payment and any monthly savings with discipline. Most people don't. If the alternative to a down payment is spending the money on consumption (not investing it), then buying forces savings through equity buildup that wouldn't otherwise happen. The forced savings effect of homeownership is real and valuable for many people -- it's why homeowners historically have much higher net worth than renters at every income level, even in markets where the pure math favors renting.
