Both paths use the owner's upfront and monthly cash budget. Ending home equity or renter investments are subtracted from that common budget.

Educational estimate only, not financial advice. The model assumes steady rates and annual changes; PMI is estimated on the original loan amount and assumed to cancel once the balance reaches 78% of the original home price, per U.S. federal law. It excludes taxes on investments or a home sale, renovations, utilities, tax deductions, and transaction timing.
How the Rent vs Buy Calculator works
- Enter the home, mortgage, PMI, rent, security deposit, HOA, ownership-cost, growth, and time-horizon assumptions for one comparable housing choice.
- The buying path amortizes the mortgage monthly, adds PMI while the loan balance is above 78% of the original home price if your down payment was under 20% (then cancels it automatically), and grows the home value at your assumed annual appreciation rate.
- The renting path invests the avoided down payment and closing costs (holding back the security deposit until it is returned at move-out), then adds or withdraws the monthly difference between owning and renting.
- At the end, the tool compares estimated home sale proceeds with the renter's investment balance, and plots both paths year by year on a chart.
The comparison method
Owner proceeds = home value * (1 - selling-cost rate) - mortgage balance Renter balance next month = current investments * (1 + monthly return) + owner costs - renter costs Modeled advantage = owner proceeds - renter investments
Annual appreciation and investment returns are converted to equivalent monthly rates. Rent changes once per completed year. Property tax, homeowners insurance, HOA fees, and maintenance are modeled as monthly costs against the home's current estimated value. PMI is charged on the original loan amount until the mortgage balance reaches 78% of the original home price, the automatic-termination point set by the U.S. Homeowners Protection Act. Because every assumption is uncertain, test conservative and optimistic scenarios instead of treating one result as a forecast.
FAQ
How does this Rent vs Buy Calculator compare the two choices?
It gives both paths the same starting cash and monthly housing budget. The buyer builds home equity, while the renter invests the down payment, closing costs, and any monthly savings. Their projected ending values are compared after estimated home-selling costs.
What does net sale proceeds mean?
It is the projected home value at the end of your stay, minus the remaining mortgage and the selling-cost percentage you entered. It estimates what the owner could keep after selling, before any applicable taxes.
How is the renter investment balance calculated?
The renter starts by investing the down payment and purchase closing costs avoided. Each month, the portfolio earns the assumed return and receives the amount by which owning costs more than renting. If renting costs more, that difference is withdrawn.
Does a result saying buying leads mean I should buy?
No. The result only describes the assumptions entered. Affordability, job stability, flexibility, local risks, taxes, financing eligibility, and personal preferences can matter more than the modeled difference.
What costs are not included?
The model excludes utilities, renovations, tax deductions, capital-gains or investment taxes, moving costs, and differences in the size or quality of the homes being compared. Mortgage insurance (PMI), HOA fees, and a returnable security deposit are included.
How does the calculator handle private mortgage insurance (PMI)?
If your down payment is under 20% of the home price, the tool charges monthly PMI on the original loan amount at the rate you enter, then automatically stops it once the mortgage balance falls to 78% of the original home price - the point U.S. federal law requires PMI to end. Total PMI paid is shown as its own result.
What happens to the renter's security deposit in the comparison?
The deposit (in months of rent) is held back from the renter's invested cash for the length of your stay, since it is not earning a return while the landlord holds it, then it is added back to the renter's investment balance at the end, assuming it is returned in full.
Are my financial details saved or uploaded?
No. All calculations run locally in your browser. The tool has no account or backend, and refreshing the page restores the sample assumptions.

A transparent planning model compared with a basic payment comparison and a do-it-yourself spreadsheet. Online Tool Store is suited to fast scenario comparisons with visible assumptions and no setup. A spreadsheet may be better when you need local tax rules, irregular repairs, refinancing, HOA schedules, or other custom cash flows.
