About Rent vs Buy Calculator
Compare the cost of renting vs buying a home. This calculator provides instant results with step-by-step explanations to help you understand the calculation process.
Formula
Compare total costs over time
How to use this calculator
- Enter the monthly rent, or the expected monthly mortgage payment if you are buying.
- Add the upfront costs, such as the down payment and any closing costs.
- Enter ongoing homeownership costs like property tax, insurance, and maintenance.
- Set the time period you want to compare, then calculate the total cost for renting and for buying.
The formula explained
The comparison adds up each option over the same time period. For renting, this is usually \(\text{total rent} = m \times n\), and for buying it is usually \(\text{total buy} = \text{upfront costs} + n \times (\text{monthly mortgage} + \text{taxes} + \text{insurance} + \text{maintenance})\).
- m = monthly rent or monthly housing payment
- n = number of months in the comparison period
- \(\text{upfront costs}\) = down payment and any closing costs paid at the start
- \(\text{monthly mortgage}\) = the monthly loan payment on the home
- \(\text{taxes}\) = monthly property tax cost
- \(\text{insurance}\) = monthly homeowner's insurance cost
- \(\text{maintenance}\) = average monthly repair and upkeep cost
Step by step method
- Find the time period you want to compare, such as \(36\) months.
- Compute renting cost with \(\text{total rent} = m \times n\).
- Compute buying cost by adding upfront costs and all monthly homeownership costs over \(n\) months.
- Compare the two totals, and the lower one is the cheaper option for that time period.
Worked example
Problem. Suppose rent is \(1{,}800\) dollars per month. Buying requires a \(25{,}000\) dollar down payment, plus \(1{,}200\) dollars per month for the mortgage, \(250\) dollars for taxes, \(100\) dollars for insurance, and \(150\) dollars for maintenance. Compare the cost over \(36\) months.
- Renting cost: \(1{,}800 \times 36 = 64{,}800\) dollars.
- Buying monthly cost: \(1{,}200 + 250 + 100 + 150 = 1{,}700\) dollars.
- Buying total cost: \(25{,}000 + 36 \times 1{,}700 = 25{,}000 + 61{,}200 = 86{,}200\) dollars.
Answer. Over \(36\) months, renting costs \(64{,}800\) dollars and buying costs \(86{,}200\) dollars, so renting is cheaper in this example.
Tips and common mistakes
- Make sure you compare the same number of months for both options, or the result will be misleading.
- Do not forget costs like taxes, insurance, maintenance, and closing costs, because they can change the answer a lot.
Frequently asked questions
How do I use the rent vs buy calculator?+
Enter the home price, down payment, mortgage rate, loan term, rent amount, and the other costs the tool asks for, such as taxes, insurance, and maintenance. The calculator compares the total monthly and long term cost of renting versus buying so you can see which option is cheaper over your chosen time period.
What costs should I include when buying a home?+
Include the mortgage payment, property taxes, homeowners insurance, maintenance, and any HOA fees if they apply. If you have private mortgage insurance, closing costs, or a one time down payment, those can also affect the comparison, especially in the early years.
What does the break even point mean in a rent vs buy comparison?+
The break even point is the time when the total cost of buying becomes lower than the total cost of renting, or the reverse depending on your inputs. It helps you see how long you need to stay in the home before buying starts to make financial sense.
How does the calculator handle a low down payment or mortgage insurance?+
A smaller down payment usually increases the loan amount and monthly mortgage payment, and it may also add mortgage insurance. That makes buying more expensive at first, so the calculator can show how much that changes the rent versus buy result.
What is the difference between renting and buying in this calculator?+
Renting usually means a lower upfront cost and more flexibility, but your monthly payment does not build ownership. Buying usually has higher upfront and ongoing costs, but part of the payment goes toward equity and the home may gain value over time.
