Highly simplified estimate using approximate appreciation and tax/insurance loads. Rent builds no equity; buying does. Estimate only — not financial advice.
Renting and buying are not just a monthly comparison. Rent payments build no equity, while a mortgage gradually converts your payments into ownership and benefits from any home appreciation.
The right answer depends heavily on how long you plan to stay. Buying usually wins over a longer horizon because upfront costs are spread across more years and equity has time to grow.

The Formula & Assumptions
Own monthly ≈ P&I + taxes + insurance
Rent paid = rent × 12 × years
(adjusted for modest increases)
Equity ≈ appreciated value
− remaining loan balance
The owning cost combines principal and interest with an estimated tax-and-insurance load. Rent is projected across your stay with a light upward adjustment for typical increases.
Equity is estimated from modest annual appreciation minus your paydown of the loan balance. Real results depend on the local market, your maintenance costs, and tax treatment.
This is a simplified planning model, not financial advice. It excludes maintenance, HOA dues, the tax deductibility of interest, and the opportunity cost of your down payment. Use it to frame the decision, then talk to a professional.
Frequently Asked Questions
When does buying beat renting?
Buying tends to win when you stay long enough to spread the upfront costs across many years — often five to seven years or more. Over a short horizon, transaction costs can outweigh the equity you build.
Does renting really cost more in the long run?
Rent payments build no equity and usually rise over time, while a fixed-rate mortgage payment stays level on principal and interest. Over many years, ownership often costs less and leaves you with an asset.
What costs does buying add that renting does not?
Homeowners pay property taxes, insurance, maintenance, and often HOA dues, plus closing costs upfront. This calculator includes taxes and insurance but you should budget separately for upkeep.
Is this calculator financial advice?
No. It is a simplified planning tool. Your decision should also weigh job stability, lifestyle, local market trends, and tax considerations. Speak with a licensed professional before committing.
