Educational estimate only, not financial advice. The model assumes steady rates and annual changes; it excludes taxes on investments or a home sale, mortgage insurance, HOA fees, renovations, utilities, tax deductions, and transaction timing.
How the Rent vs Buy Calculator works
- Enter the home, mortgage, rent, ownership-cost, growth, and time-horizon assumptions for one comparable housing choice.
- The buying path amortizes the mortgage monthly and grows the home value at your assumed annual appreciation rate.
- The renting path invests the avoided down payment and closing costs, 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.
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, and maintenance are modeled as percentages of the home's current estimated value. 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 If renting costs more, that difference is withdrawn.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 mortgage insurance, HOA fees, utilities, renovations, tax deductions, capital-gains or investment taxes, security deposits, moving costs, and differences in the size or quality of the homes being compared.
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.
How we compare
A transparent planning model compared with a basic payment comparison and a do-it-yourself spreadsheet.
| Feature | Online Tool Store | Basic calculator | Spreadsheet |
|---|---|---|---|
| Down payment opportunity cost | Invested in renter portfolio | Often omitted | Manual formula needed |
| Monthly cash-flow differences | Invested or withdrawn monthly | Payment-only comparison | Possible with careful setup |
| Home sale costs and mortgage balance | Included | Varies | Manual formula needed |
| Annual projection table | Included | Usually not included | Must be built |
| Multiple currency formats | Seven formats | Usually one currency | User-defined |
| Inputs stay in the browser | Explicitly local | Varies | Depends on software |
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.
