What is a rent vs. buy calculator?
A Rent vs. Buy Calculator compares the total cost of buying a home with the total cost of renting a similar one over the years you expect to stay. Comparing rent with a mortgage payment is not enough: buying also involves a down payment, closing costs, property tax, insurance, maintenance and selling costs, while renting involves rent increases and the chance to invest the cash you did not put into a house.
How to use it
- Home Purchase: enter the price, down payment, rate, term, buying and selling costs, property tax, insurance, HOA, maintenance and expected appreciation.
- Home Rent: enter the monthly rent, expected yearly increase, renter’s insurance, deposit and any upfront cost.
- Your Information: enter the return you expect on invested savings, your federal and state marginal tax rates and your filing status.
- Click Calculate. The results table shows the average monthly and annual cost of buying and of renting for each length of stay.
What to Expect When Buying a Home
Buying a home can provide long-term stability and the opportunity to build equity, but homeownership also comes with significant upfront and recurring expenses. The initial costs can include the down payment, closing costs, inspection fees, appraisal charges, and other transaction expenses. After purchasing, homeowners generally need to account for the major components of their mortgage and housing expenses, often referred to as PITI:
- Principal: The portion of the mortgage payment that reduces the amount borrowed and builds home equity.
- Interest: The cost paid to the lender for borrowing money.
- Taxes: Property taxes charged by the applicable local government or taxing authority.
- Insurance: Homeowners insurance that protects against covered property risks. Some borrowers may also need private mortgage insurance (PMI) when the down payment is below certain requirements.
Homeowners should also budget for maintenance, repairs, HOA or condominium fees, and the costs associated with eventually selling the property.
What to Know When Renting and Factors That Affect the Decision
Renting generally requires less money upfront than purchasing a home and can provide greater flexibility for people who may move within a few years. The main expense is the monthly rent, although renters may also have additional costs such as a security deposit, application fees, and renter’s insurance. Before signing a lease, it is useful to consider:
- Rent increases: Future increases can significantly change the long-term cost of renting.
- Security deposit: This is commonly required before moving into a rental property.
- Lease terms: A fixed lease can provide predictable rent for the agreed period.
- Flexibility: Renting can be useful for people who expect changes in their job, location, or lifestyle.
- Maintenance: Major property repairs are generally the landlord’s responsibility, although renters remain responsible for obligations stated in the lease.
The financial decision between renting and buying is also influenced by the expected investment return on money that could otherwise be used for a down payment, the expected appreciation of the home, mortgage interest rates, property taxes, insurance, maintenance, and buying or selling costs.
How the calculator compares the two
For each year you might stay, the calculator adds up what you pay and subtracts what you get back:
- Cost of buying = down payment + buying costs + mortgage payments + property tax + insurance + HOA + maintenance + selling costs − the home’s sale value − any tax saving.
- Cost of renting = rent + renter’s insurance + upfront costs − the growth you would have earned by investing the down payment and buying costs instead.
The tax saving is estimated only when your mortgage interest and property tax are larger than the standard deduction. The calculator uses the 2026 standard deduction: $16,100 for single filers and married filing separately, $32,200 for married filing jointly and $24,150 for heads of household (2026, source: IRS Rev. Proc. 2025-32).
Example
Imagine a $400,000 home with 20% down at 6.5% for 30 years versus renting a similar home for $2,200 a month with 3% yearly increases. Because buying and selling costs are large, renting usually comes out cheaper if you move within the first few years. The longer you stay, the more those one-time costs are spread out and the more equity you build, so buying tends to win after a break-even point. Enter your own numbers to see where that point falls for you.
Tips
- Be realistic about appreciation; small changes in this input move the result a lot.
- Include maintenance. Many owners budget around 1% of the home’s value a year.
- Think about how sure you are of your plans. Flexibility has value that no calculator can price.
Frequently Asked Questions
It depends on prices, rates and rents where you live, but because buying and selling a home can cost several percent of its price, buying often needs several years to catch up with renting. The results table shows the average cost of each option for every length of stay, so you can see where buying becomes cheaper for your inputs.
Yes, in a simplified way. If your mortgage interest and property tax are higher than the 2026 standard deduction for your filing status, the calculator estimates the tax saved using the marginal tax rates you enter. Many buyers take the standard deduction, in which case there is no extra saving.
Use a modest long-term figure rather than recent price jumps. Many people test a range, for example 2%, 3% and 4% a year, to see how sensitive the answer is.
They are paid up front and at the end, no matter how long you stay. On a short stay they are spread over only a few years, which makes buying expensive; on a long stay their yearly cost becomes small.
No. Rent buys housing and flexibility, just as mortgage interest, property tax and maintenance are costs of owning that you do not get back. What matters is the total cost of each option over your stay, which is what this calculator compares.
