What This Calculator Does
This rent vs. buy calculator provides a comprehensive financial comparison between renting and buying a home over 5-year and 10-year time horizons. It accounts for mortgage payments (principal and interest), property taxes, insurance, maintenance costs, home appreciation, equity buildup, rent increases, and the opportunity cost of investing the down payment elsewhere. The goal is to help you determine which option builds more wealth based on your specific financial inputs and local 2026 market conditions.
The Formula
Cumulative buy costs include all mortgage payments, property taxes, insurance, and maintenance over the analysis period. Equity built equals the appreciated home value minus the remaining loan balance. The net cost of buying subtracts the equity position from total costs paid. The comparison determines whether the total rent paid or the net buying cost is lower at each time horizon.
Step-by-Step Example
Set up the buying scenario
Home price: $400,000. Down payment: 20% ($80,000). 30-year fixed at 6.75%. Property tax: 1.1%. Insurance: $1,800/year. Maintenance: 1% of home value annually.
Set up the renting scenario
Monthly rent: $2,200 with 3% annual increases. The $80,000 down payment could earn 7% annually if invested in the stock market.
Compare at 5 years
After 5 years, total rent paid is approximately $140,000. Total buy costs are approximately $155,000, but you have built roughly $125,000 in equity (from appreciation and principal paydown).
Compare at 10 years
After 10 years, total rent paid is approximately $302,000. Total buy costs are approximately $310,000, but equity has grown to approximately $240,000, making buying the clear winner in most scenarios.
Real-World Use Cases
First-Time Homebuyer Decision
Determine whether buying makes financial sense in your market given current 2026 mortgage rates of 6.5-7.0% and local home prices, or if renting and investing the difference builds more wealth.
Relocation Planning
If you plan to live somewhere for only 2-3 years, this calculator shows whether the transaction costs of buying and selling outweigh the equity benefits.
Investment Analysis
Compare the wealth-building potential of homeownership (leveraged real estate) against investing the same capital in diversified stock market index funds.
Common Mistakes to Avoid
Only comparing the monthly mortgage payment to monthly rent. The true cost of ownership includes property taxes, insurance, maintenance, and opportunity cost of the down payment.
Assuming home values always appreciate. While the long-term national average is 3-4% annually, local markets can decline, especially in overheated markets.
Ignoring the tax benefits of homeownership. Mortgage interest and property tax deductions can reduce the effective cost of buying, though the 2026 standard deduction limits this benefit for many buyers.
Not accounting for rent increases. At 3% annual increases, $2,200 rent becomes $2,955 in 10 years. This makes buying more attractive over longer time horizons.
Forgetting transaction costs when selling. Selling a home costs 7-9% of the sale price in agent commissions, closing fees, and transfer taxes.
