Rent vs Buy Calculator
How Does the Rent vs Buy Calculator Work?
This rent vs buy calculator helps you easily compare the long-term financial benefits of renting a home versus buying one. By entering your monthly rent, expected rent increases, home price, down payment, mortgage rate, property taxes, home appreciation, and how long you plan to live there, you'll see whether renting or buying is better financially over time.
The calculator considers all the major financial factors, including rent increases, mortgage payments, home appreciation, property taxes, and maintenance costs, to show you a clear comparison. This helps you make a well-informed decision about whether buying or renting makes the most sense for your personal situation.
Why Use a Rent vs Buy Calculator?
Choosing between renting or buying can be complicated. Both options have hidden costs and financial considerations. Many people assume buying is always better, but that isn’t always true—especially if you don't plan to stay in the home long-term. This calculator clarifies the financial implications of both choices.
Using this tool helps you see clearly which option saves you money and builds wealth over your intended time frame, empowering you to make smarter financial decisions.
Understanding Your Rent vs Buy Results
The calculator provides a detailed comparison of renting vs. buying over your chosen timeframe. It calculates how much you'll pay in total rent, accounting for annual rent increases. For buying, it considers your mortgage payments, taxes, and maintenance costs while subtracting home equity gains from appreciation and loan repayments.
You'll clearly see the net cost of renting compared to the net cost (or wealth) gained from buying, helping you decide whether purchasing a home is financially advantageous.
Our new fields also account for closing costs when you buy and the potential growth you miss out on by tying up cash in a down payment. Including these expenses gives a more realistic side-by-side comparison.
What Influences Rent vs Buy Decisions?
Key factors influencing whether renting or buying is smarter financially include how long you plan to stay in the home, local housing market trends, expected rent increases, mortgage rates, property taxes, and maintenance costs.
Typically, buying makes more financial sense the longer you plan to stay, especially if home prices increase steadily. Short-term stays generally favor renting, as homeownership costs are spread out over time.
Who Should Use This Calculator?
This calculator is ideal for first-time homebuyers, individuals relocating to new cities, or anyone weighing the pros and cons of renting versus buying. Real estate professionals, mortgage lenders, and financial advisors also use this tool to help clients clearly see the long-term financial impacts of their housing decisions.
By using this calculator early in your decision-making process, you can confidently choose the housing option that best suits your personal financial goals and lifestyle.
The Logic Behind the Comparison
The calculator evaluates rent and buy scenarios using a series of equations. Rent payments are modeled as a geometric series growing by the annual rent increase rate. The total rent after years is , where is the first year’s rent and the rent growth rate. For buying, the calculator computes the monthly mortgage using the standard amortization formula , with principal , monthly interest rate , and total payments . These calculations feed into cost totals along with taxes, maintenance, and the opportunity cost of tying up cash in a down payment.
Worked Example
Consider a renter paying $1,500 per month with a 3% annual increase. They could buy a $320,000 home with a $64,000 down payment, a 30‑year mortgage at 4%, and expect 2% annual home appreciation. Property tax is 1.2%, maintenance costs are 1% of home value, and annual insurance is $900. They plan to stay for five years and believe invested cash could earn 5% annually. Plugging these numbers into the calculator yields total rent payments of about $94,000. Buying produces a monthly mortgage of $1,226, total mortgage payments of roughly $73,600 over five years, taxes of $19,200, maintenance and insurance totaling $22,400, and closing costs around $9,600. The opportunity cost of the down payment and closing costs is approximately $20,000. After accounting for an estimated $32,000 in equity gained from appreciation and principal paydown, the net buying cost is close to $92,800. In this scenario, buying edges out renting by a small margin, suggesting either option is financially viable depending on other preferences like flexibility or desire for ownership.
Comparison Snapshot
| Factor (5-year total) | Renting | Buying |
|---|---|---|
| Total Payments | $94k | $114k |
| Equity Gained | $0 | $32k |
| Net Cost | $94k | $92.8k |
Tables like this make it easy to visualize trade-offs and see which variables drive the decision. Try adjusting appreciation or rent growth to see how sensitive the outcome is.
Assumptions and Limitations
All projections rely on estimates. Rent increases may fluctuate, property taxes can change with local policy, and maintenance costs are unpredictable. The opportunity cost assumes a constant rate of return on investments, which real markets rarely deliver. Additionally, the model does not include tax deductions such as mortgage interest or potential capital gains exclusions on home sales. Use the results as a guide rather than a guarantee.
Beyond the Numbers
Financial calculations are only part of the decision. Renting offers flexibility, lower upfront costs, and fewer maintenance responsibilities. Buying builds equity and locks in housing costs but ties you to a location. Think about job stability, family plans, and your tolerance for home repairs when weighing the options. Some people value the freedom to relocate quickly, while others prioritize customizing their living space and building long-term wealth through homeownership.

Whichever path you choose, revisit the comparison annually. Markets evolve and personal circumstances change—rent may rise faster than expected, or interest rates may drop, opening a window for a more favorable mortgage. Regular check-ins keep your housing strategy aligned with both financial realities and personal goals.
