Cash Flow Notes:

  • Day 0: Down payment + closing costs + points (buying) versus the refundable security deposit (renting); these amounts are not delayed or discounted by a year.
  • Years 1-10: Direct ownership cash costs versus rent and renter insurance, discounted at your selected rate.
  • Year 10: Final-year costs plus sale value, selling costs, remaining mortgage, and estimated gain tax (buying) versus final-year rent and the fully returned refundable deposit (renting).
  • Terminal inflows: Gross home value (offset by selling costs, mortgage payoff, and estimated gain tax) versus return of the full refundable deposit. Investment opportunity cost is shown in the net-worth comparison, not counted again in NPV.
  • NPV: Present value of net cash flows (inflows - outflows) discounted at 10% annually

Tax Calculation Details

Methodology

  1. Opportunity cost: If renting, the down payment + buyer closing costs + points (minus deposit) are invested on day 0; every month the difference (owning cash − renting cash) is also invested. If the difference is negative (renting costs more than owning), that amount is added to the buy side instead of withdrawn from rent. A flat annual return compounds monthly.
  2. Extra principal: Add a global monthly extra, one‑time extras, and/or period‑limited monthly extras (including open‑ended until payoff). Extra principal shortens PMI and reduces interest.
  3. Mortgage + PMI: Fully amortizing monthly payment. PMI is modeled as a percentage of the original loan until equity based on original value reaches the selected stop threshold; actual cancellation rules can differ.
  4. Property tax/maintenance/insurance: Property tax & maintenance scale with home value; HOI & HOA are flat as entered.
  5. Tax benefit: Each year, incremental tax savings from owning are deposited into the buyer-side investment account. Filing status presets help set deduction/SALT caps but are editable.
  6. Sale proceeds: "Buy wealth" assumes immediate sale at the horizon, subtracts selling costs and the remaining loan, and estimates tax on gain after the modeled primary-residence exclusion when eligible.
  7. Breakeven simulator: When no breakeven is found within the selected horizon, use the simulator to test different scenarios (note rate, down payment, home appreciation, rent, home price, investment return) to find the conditions where buying becomes better than renting.

Explanation of Terms

  • Opportunity cost: The potential return you could earn by investing money instead of using it for a down payment or home equity.
  • PMI (Private Mortgage Insurance): Insurance required when your down payment is less than 20% of the home's value.
  • LTV (Loan-to-Value): The ratio of your loan amount to the home's value, used to determine PMI cancellation.
  • Amortization: The process of paying off a loan through regular payments that include both principal and interest.
  • Property appreciation: The expected annual increase in home value over time.
  • Closing costs: One-time fees paid when purchasing a home, including title insurance, escrow, and lender fees.
  • SALT cap: State and Local Tax deduction limitation under current tax law.

How to Use the Rent vs Buy Calculator

Step 1: Set Your Housing Timeline for Rent vs Buy Analysis

Choose how long you plan to stay in the home. This comprehensive renting vs buying analysis compares the total cost of renting versus buying over your specified time period. The housing affordability breakeven point varies significantly based on your timeline - shorter stays typically favor renting while longer stays often favor buying. This helps determine when buying a home makes financial sense.

Step 2: Enter Home Purchase and Mortgage Details

Input the home price, down payment amount or percentage, mortgage note interest rate, and loan term for your mortgage analysis. Include closing costs, mortgage points, and selling costs. The calculator accounts for modeled PMI, property taxes, homeowners insurance, HOA fees, and maintenance costs that scale with home value.

Step 3: Define Your Rental Housing Scenario

Enter your current monthly rent, expected annual rent increases, renter's insurance, and security deposit. The buy vs rent calculator compares your monthly rental payments against the total cost of homeownership, including mortgage payments, property taxes, homeowners insurance, maintenance, and opportunity costs. This own vs rent analysis helps determine your most affordable housing option.

Step 4: Configure Investment and Real Estate Market Assumptions

Set your expected annual investment return rate and home appreciation rate for accurate real estate calculator results. The calculator shows how your down payment and monthly savings (if renting costs less than owning) would perform if invested instead. This opportunity cost analysis is crucial for accurate renting vs buying comparisons and determining whether real estate or alternative investments offer better returns.

Rent and invest the difference

Rent vs invest delta: what happens to the monthly savings?

This rent vs buy calculator already models the rent-and-invest strategy: money that would have gone into the home upfront stays invested, and the cheaper housing path invests its monthly cash-flow advantage. Compare the resulting net worth with home equity over the same period.

How to use this tool

  1. Compare equivalent homes

    Enter a realistic purchase price and rent for housing that meets the same needs.

  2. Include the full owning cost

    Mortgage payments, property taxes, insurance, maintenance, PMI and HOA charges all affect the cash-flow difference.

  3. Choose investment assumptions

    Set the expected investment return, investment-tax assumptions and horizon. Test lower returns as well as your central estimate.

  4. Read the investment decomposition

    Review initial funds and monthly deltas separately, then compare ending wealth after the modeled sale and taxes.

The rent-and-invest monthly delta

The monthly delta is owning cash outflow minus renting cash outflow. If owning costs $3,000 and renting costs $2,200, the renter has $800 available to invest that month. At unchanged costs and a 0% return, twelve such deposits total $9,600 before modeled annual tax adjustments.

The model also invests upfront cash not used for a down payment and buyer closing costs, after allowing for the renter’s security deposit. The returned deposit is accounted for separately. A lower rent alone does not create investment wealth unless you actually save the difference.

When owning costs less each month

If renting has the higher monthly cash outflow, the calculator invests the difference on the buying side instead. This gives both choices the same housing cash budget rather than assuming only renters can invest.

Owner tax savings reduce the renter’s relative investable advantage under the entered tax assumptions. Review the detailed cash-flow and tax breakdowns alongside the investment chart.

Portfolio value versus home equity

A fair comparison includes both sides of the balance sheet. The buying path includes modeled home value, remaining mortgage debt, sale costs, applicable capital-gains assumptions and investments from any monthly advantage. The renting path includes its portfolio after modeled investment taxes and the refundable deposit.

Returns, rent increases, home appreciation and repair expenses are uncertain. Change these assumptions to see whether the result depends on a narrow forecast.

Frequently asked questions

Is rent vs invest delta a separate calculator?

The rent-and-invest delta is already included here. Use the monthly cash-flow comparison and Renter Investment Decomposition to see invested upfront funds and monthly savings separately.

Does the calculator invest the down payment if I keep renting?

Yes. Cash not used for the modeled home purchase is invested on the renting side after accounting for the renter’s deposit. Monthly cash-flow advantages are invested as well.

Can buying win even if renting costs less per month?

Yes. Ending wealth also depends on home appreciation, mortgage paydown, upfront and selling costs, investment performance and tax assumptions. Monthly affordability and long-term net worth answer different questions.
