How to Use Our Rent vs. Buy Calculator
Use the calculator above to test whether renting or buying looks lower-cost over the period you expect to stay put.
Our calculator looks beyond the monthly cost of rent compared to a mortgage. Appreciation and equity growth makes a difference in renting vs. buying.
| Input |
What It Means |
Why It Matters |
| Monthly rent and rent growth |
The renting assumptions |
These determine how total rent increases over time. |
| Home price, down payment, and closing costs |
The starting ownership assumptions |
These drive upfront cash and loan size. |
| P&I, taxes, insurance, and maintenance |
The ongoing ownership costs |
These make up the monthly cost of owning in the model. |
| Appreciation and years in home |
The exit assumptions |
These drive projected home value and net equity at exit. |
How Our Rent vs. Buy Calculator Works
Our calculator compares the projected cost of renting with the projected net cost of owning over the time you expect to stay in the home.
It's just a payment comparison. It factors in factors like potential equity growth through appreciation and paydown, as well as costs like maintenance and insurance.
On the rent side, total rent paid is the sum of yearly rent, with rent increased each year by the rent-growth rate you enter. On the ownership side, total cost includes down payment, purchase closing costs, and the ongoing monthly costs of principal and interest, property taxes, insurance, and maintenance during the time you own the home.
The model then subtracts net equity at exit. Net equity equals projected home value minus the remaining mortgage balance. If the result is positive, buying is lower-cost under the assumptions entered. If the result is negative, renting is lower-cost.
Why Time Horizon Matters So Much
Rent-versus-buy outcomes often change when you change the number of years in the home.
A shorter horizon gives ownership less time to benefit from appreciation and principal paydown, while still requiring upfront down payment and closing costs.
A longer horizon gives buying more time to build equity, but it also increases the importance of assumptions like appreciation, maintenance, and future rent growth. That is why this calculator works best when you test several stay-length scenarios instead of just one.
How To Read The Result
The output is best treated as a directional planning result. It helps you see which side looks lower-cost under a consistent set of assumptions.
That does not mean it settles the decision by itself. Lifestyle flexibility, moving plans, repair risk, and the value you place on stability can matter just as much as the modeled dollar result.
Where you live matters too, given that home appreciation and rental costs vary widely by city.
What The Calculator Can And Cannot Tell You
The calculator is very useful for testing assumptions. You can change appreciation, rent growth, maintenance, or time in home and see how the answer moves.
It cannot predict future home values, rent inflation, transaction costs when you eventually sell, or the nonfinancial benefits and tradeoffs that come with either choice.
The Bottom Line
Our rent-vs.-buy calculator is most helpful when you use it to stress-test your assumptions rather than hunt for one perfect answer. Change the stay length, appreciation, and rent-growth inputs and see whether the result still points the same way.
Frequently Asked Questions
When Does Buying Usually Start To Look Better?
Buying often looks stronger when you expect to stay longer, when appreciation and principal paydown have more time to work, and when rent growth is high relative to ownership cost.
Why Does The Calculator Subtract Equity At Exit?
Because part of your ownership cost is recovered through home value and principal paydown when you leave the home.
Does The Calculator Include Maintenance?
Yes. The ownership side includes maintenance as part of the monthly housing cost assumption.
Can Renting Still Be The Better Choice?
Yes. Renting can look lower-cost when your expected stay is short or when ownership costs and upfront cash needs outweigh the modeled equity benefit.
