Calculator Description
Enter Home purchase price ($), Monthly rent ($) and Down payment (%) and the remaining scenario settings to review net financial difference with this tool. Mortgage principal builds modeled equity while interest and other ownership charges are expenses.
Compare the modeled net costs of renting and buying over the same stay. Include ownership equity and the alternative use of the down payment.
Mortgage principal builds modeled equity while interest and other ownership charges are expenses. Rent and ownership therefore cannot be compared using payments alone.

Frequently Asked Questions
What information do I need for the Rent vs Buy Calculator?
Prepare Home purchase price ($), Monthly rent ($), Down payment (%), Interest rate (%), Loan term (years), Property tax rate (%), Home insurance ($/year), PMI rate (%), HOA fees ($/month), Maintenance (%), Home appreciation (%/year), Rent increase (%/year), Holding period (years) and Investment return (%). Keep the time horizon fixed and test appreciation and investment-return assumptions separately from the starting rent and purchase price.
How can the holding period change a rent-versus-buy comparison?
Mortgage principal builds modeled equity while interest and other ownership charges are expenses. Rent and ownership therefore cannot be compared using payments alone. Appreciation, rent growth, opportunity cost and holding period drive the answer. This model omits some transaction and tax effects and uses simplified PMI behavior.
How can I check the rent vs buy calculator with an example?
Use the full settings in the worked-example table. They produce Net Financial Difference: $9446; Equity after 5 years: $143635. Compare the method and units as well as the displayed number.
Which assumptions apply to this rent vs buy calculator?
Taxes, insurance, maintenance and HOA remain at entered levels. PMI is held constant through the loan term when down payment is below 20%; cancellation, transaction costs and tax benefits are not modeled. Mortgage payments stop at loan maturity. Keep the time horizon fixed and test appreciation and investment-return assumptions separately from the starting rent and purchase price.
When should I verify the rent vs buy calculator result elsewhere?
Appreciation, rent growth, opportunity cost and holding period drive the answer. This model omits some transaction and tax effects and uses simplified PMI behavior. For a transaction or account decision, compare the inputs with the applicable statement, contract or official rules.

How to Use This Calculator
- Keep the time horizon fixed and test appreciation and investment-return assumptions separately from the starting rent and purchase price.
- Fill in Home purchase price ($), Monthly rent ($), Down payment (%) and Interest rate (%); then complete the other fields shown for your selected mode. Use the field units rather than copying an unlabeled value.
- For a result check, reproduce the example beginning with Home purchase price ($) = 350000 and Monthly rent ($) = 1800; copy the remaining settings from the detailed guide.
- Use the page's Calculate or Convert control, or read the updated result where the tool recalculates automatically. Locate Net Financial Difference and any supporting breakdown.
- Interpret the result with this distinction in mind: Mortgage principal builds modeled equity while interest and other ownership charges are expenses. Keep the selected inputs alongside the output when comparing scenarios.
Practical example and result check
Worked rent vs buy calculator example. Set Home purchase price ($) = 350000; Monthly rent ($) = 1800; Down payment (%) = 20; Interest rate (%) = 6.5; Loan term (years) = 30 years; Property tax rate (%) = 1.2; Home insurance ($/year) = 1200; PMI rate (%) = 0.5; HOA fees ($/month) = 0; Maintenance (%) = 1; Home appreciation (%/year) = 3; Rent increase (%/year) = 3; Holding period (years) = 5; Investment return (%) = 7. The corresponding output is Net Financial Difference: $9446; Equity after 5 years: $143635. Mortgage principal builds modeled equity while interest and other ownership charges are expenses.
Before relying on the result
- Confirm the units, dates, rates and time periods entered.
- Review which costs, measurements or assumptions are included and excluded.

Follow the calculation
Relationship used for this example: Net buying cost = down payment + ownership outlays − terminal equity + opportunity cost of down payment.
Mortgage principal builds modeled equity while interest and other ownership charges are expenses. Rent and ownership therefore cannot be compared using payments alone.
Assumptions for this model: Taxes, insurance, maintenance and HOA remain at entered levels. PMI is held constant through the loan term when down payment is below 20%; cancellation, transaction costs and tax benefits are not modeled. Mortgage payments stop at loan maturity.
