Introduction
The rent versus buy decision changed dramatically when mortgage rates climbed from 3% to 7% between 2022 and 2024. At 3%, buying beat renting in most U.S. markets within 2 to 3 years. At 7% on a $450,000 home, the monthly cost of ownership often exceeds comparable rent by $800 to $1,200 — and takes 7 to 9 years to break even with appreciation included. According to the Federal Reserve Bank of Atlanta's Home Ownership Affordability Monitor, the share of income required to purchase a median-priced U.S. home reached 40% in late 2023 — the highest since tracking began in the 1990s. Yet renting forfeits equity accumulation, leaving renters exposed to rent increases and with no asset after 30 years. This calculator models both scenarios side by side — including down payment opportunity cost, home appreciation, equity buildup, and rent inflation — to show which option builds more net worth at your specific time horizon and market.
What This Calculator Does
This rent vs. buy calculator provides a comprehensive 5-year and 10-year financial comparison between renting and buying. For buying, it models mortgage payments (P&I), property taxes, insurance, maintenance, HOA fees, home appreciation, and equity buildup from principal paydown. For renting, it models cumulative rent paid, annual rent inflation, and the investment growth of the down payment if invested instead. The output shows net wealth at each horizon under both scenarios, identifying which option builds more long-term net worth given your specific inputs.
The Formula
Home equity equals the appreciated home value minus the remaining mortgage balance minus selling costs (approximately 7% to 9% of sale price). For renting, the down payment and monthly savings versus buying are assumed invested at a market return rate. The comparison identifies the crossover point where cumulative equity appreciation minus buying costs exceeds the investment portfolio value a renter would accumulate with the same capital.
Step-by-Step Example
Set up the buying scenario
Home price $425,000. Down payment 20% ($85,000). 30-year fixed at 6.875%. Annual property tax 1.2% ($5,100). Insurance $2,000/year. Maintenance 1% ($4,250/year). Assumed appreciation 3.5%/year.
Set up the renting scenario
Monthly rent $2,400 with 3% annual increases. The $85,000 down payment plus $300/month rent-vs-buy monthly savings invested at 7% annual return.
Compare at 5 years
Buying: Total payments $186,000, equity $163,000 (appreciation + paydown - selling costs). Net buying wealth: ~$78,000. Renting: Cumulative rent ~$154,000, invested down payment grows to ~$122,000. Net renting advantage at year 5: renting leads by ~$44,000.
Compare at 10 years
Buying: Total payments $372,000, equity $265,000. Net buying wealth: ~$180,000. Renting: Cumulative rent ~$333,000, invested portfolio ~$200,000. At year 10, buying has produced comparable or greater net worth in most scenarios at these inputs.
Real-World Use Cases
First-Time Buyer Decision in a High-Cost Market
A San Francisco renter paying $3,200/month models whether buying a $900,000 condo (20% down) makes sense with current rates at 6.875%. The analysis shows a 9-year break-even — longer than their expected 5-year stay — suggesting renting and investing the $180,000 down payment produces higher net worth over their actual planning horizon.
Relocation Decision
A professional relocating for a 3-year job assignment uses the calculator to confirm that buying and selling within 3 years at 7% to 9% selling costs and a 6-year break-even point virtually guarantees a financial loss versus renting for the assignment period.
Long-Term Wealth Building Comparison
A 30-year-old comparing a $350,000 home purchase against investing the $70,000 down payment models outcomes over 20 years. At 3.5% appreciation versus 7% stock market returns, the model shows homeownership building greater after-tax wealth due to leverage and inflation protection once the 7-year break-even is cleared.
Comparison
| Hold Period | Market | Rate | Down Pmt | Buy or Rent Wins? | Break-Even |
|---|---|---|---|---|---|
| 3 years | Average appreciation | 6.875% | 20% | Renting wins | 7+ years |
| 5 years | Average appreciation | 6.875% | 20% | Close/Renting slight edge | 6-8 years |
| 7 years | Average appreciation | 6.875% | 20% | Buying wins | ~7 years |
| 10 years | High appreciation | 6.875% | 20% | Buying wins clearly | 5-6 years |
| 5 years | Average appreciation | 6.0% | 20% | Buying slight edge | 4-5 years |
Common Mistakes to Avoid
Comparing only monthly mortgage payment to monthly rent. The true cost of ownership includes property taxes (1% to 2.5% of value annually), insurance, maintenance (1% of value annually), HOA fees, and the opportunity cost of the down payment. These add $1,000 to $1,800/month to typical ownership costs that the basic payment comparison ignores.
Assuming home values always appreciate. Long-term U.S. home values have increased at approximately 3% to 4% annually, but local markets and time periods vary dramatically. Properties purchased in 2006 at peak prices took 10+ years to recover in many markets.
Ignoring transaction costs when selling. Selling a home costs 7% to 9% of the sale price in agent commissions, closing fees, and transfer taxes. On a $450,000 home, that is $31,500 to $40,500 in one-time exit costs that must be recovered by appreciation before buying beats renting.
Not factoring in rent inflation. At 3% annual increases, $2,200 rent becomes $2,550 in 5 years and $2,955 in 10 years. This cumulative rent increase makes renting progressively more expensive over time and improves buying's relative position at longer hold periods.

Housing market performance and investment returns are not predictable. Consult a financial advisor and mortgage professional before making homebuying decisions.
Conclusion
This decision is heavily dependent on your local market, how long you plan to stay, and current mortgage rates. If your break-even horizon exceeds your expected stay, renting and investing the difference typically wins. Once you decide to buy, confirm exact affordability with the Mortgage Payment Calculator and budget all upfront costs with the Closing Cost Calculator.
