Formula

Mortgage vs rent formula

Cost difference = estimated owner net cost - estimated rent cost

Owner net cost equals down payment, closing costs, and ownership payments minus estimated equity after sale. Rent cost sums monthly rent with annual rent growth.

How to use

Steps

  1. Enter current monthly rent and expected annual rent growth.
  2. Enter home price, down payment, rate, loan term, and years you expect to stay.
  3. Add property tax, insurance, HOA, maintenance, closing cost, selling cost, and home appreciation assumptions.
  4. Compare estimated owner net cost, estimated rent cost, and the cost difference over the same holding period.

Calculator use

Best for

  • Comparing rent cost with owner net cost over the same holding period.
  • Testing how down payment, rate, taxes, insurance, HOA, maintenance, rent growth, and appreciation change the result.
  • Checking whether a short stay makes closing and selling costs too important.
  • Preparing a housing scenario before talking with a lender, landlord, or housing advisor.

Before relying on it

Check first

  • Treating the result as a recommendation to rent or buy.
  • Leaving out PMI, repairs, utilities, local taxes, insurance changes, closing timing, or opportunity cost.
  • Using one appreciation or rent-growth assumption without testing a conservative case.
  • Comparing buying and renting across different locations, home sizes, or lifestyle needs.

Details

What to know before using the result

Owner net costCash out minus equity

The calculator subtracts estimated equity after sale from down payment, closing costs, and monthly ownership costs.

Rent pathAnnual growth assumption

Rent is summed month by month and increases once per year by the rent growth rate entered.

Cost differenceOwner net cost minus rent cost

A positive difference means buying costs more in the scenario. A negative difference means buying costs less in the scenario.

Sensitive assumptionsHolding period matters

Short stays can make transaction costs matter more. Long stays can make appreciation, maintenance, and rate assumptions matter more.

Next decisionPayment, affordability, DTI, or rent budget

After the comparison, use the mortgage calculator, mortgage affordability calculator, debt-to-income calculator, or rent affordability calculator to test the specific budget path.

Benchmarks

How to read the result

Close call: Within 3%.

A broad planning heuristic: small differences can be overwhelmed by repairs, rent changes, taxes, or market moves.

Short stay: Costs matter.

Closing and selling costs can dominate if you expect to move soon.

Long stay: Assumptions compound.

Appreciation, rent growth, maintenance, rate, and tax assumptions get more important over time.

FAQ

Common questions

How do I compare renting and buying?

Compare the rent paid over the same period with the owner's out-of-pocket cost after subtracting estimated equity at sale.

Does this include investment opportunity cost?

No. It focuses on direct housing cash flows and estimated equity. If down payment or closing cash would be invested elsewhere, compare that opportunity cost separately before treating the result as final.

Is the result a recommendation to rent or buy?

No. It is a planning comparison. Taxes, repairs, PMI, insurance, local market prices, lifestyle needs, and lender terms can change the decision.

Why does years staying matter?

Buying has transaction costs. A longer holding period spreads those costs across more months, while a shorter stay gives less time for equity to build.

What assumption changes the rent-versus-buy result most?

Holding period, home appreciation, rent growth, mortgage rate, maintenance cost, and transaction costs usually move the comparison the most.

Should opportunity cost be included?

Yes. Down payment and closing cash could have been saved or invested elsewhere, so opportunity cost helps compare buying with renting more fairly.
