Rent vs Buy Calculator FAQ
What is a rent vs buy calculator?
A rent vs buy calculator compares the financial cost of renting and buying a home over a chosen time period. It helps answer questions such as should I rent or buy, is it better to rent or buy a house, and when does buying break even.
How does this buy or rent calculator work?
It estimates rent-side costs and buy-side costs using your inputs for rent, home price, mortgage, appreciation, selling costs, and investment return. It then compares the two results over the selected holding period and shows which option is cheaper.
What does break-even point mean in a rent vs buy comparison?
The break-even point is the time at which buying first catches up with renting under the current assumptions. Before that point, renting has the better financial result. After that point, buying is projected to come out ahead.
What is rent ratio?
The rent ratio compares home price with annual rent. A common formula is home price / annual rent. Higher values generally make renting look relatively more attractive, while lower values generally make buying look relatively more attractive.
What costs should I include when comparing renting and buying?
For renting, include monthly rent, renter's insurance, deposits, broker or move-in fees, and any other upfront rental costs. For buying, include down payment, mortgage payments, property tax, home insurance, maintenance, HOA fees, loan costs, home appreciation, and selling costs.
Is this calculator enough to decide whether to buy or rent a house?
It is useful for screening and scenario testing, but it is still a simplified model. Real decisions may also depend on taxes, utilities, moving frequency, job flexibility, maintenance risk, and local housing-market conditions.
Example
Suppose rent is 1,500 per month and the home price is 360,000. If annual rent is 18,000, then the rent ratio is:
\[ \text{Rent ratio} = \frac{360{,}000}{18{,}000} = 20 \]
If your assumptions show buying catches up after 6 years 4 months, that means renting is financially ahead before that point, while buying is projected to be ahead if you stay longer.
