Rent vs Buy Calculator

How to use the Rent vs Buy Calculator

1. Start with the property price, down payment percentage, annual interest rate, and your current monthly rent.
2. Review loan assumptions such as mortgage term, loan type, extra monthly payments, extra annual payments, refinancing year, and refinancing fees.
3. Add advanced assumptions including property appreciation, alternative investment return, maintenance, property tax, insurance, HOA fees, rent increases, inflation, and selling costs.
4. Open the Results & Reports tab to review the recommendation, NPV comparison, yearly table, amortization schedule, sensitivity analysis, scenarios, risks, and smart advisory report.

Practical example

Assume a property price of 250,000, a 20% down payment, a 5% annual mortgage rate, and current monthly rent of 1,200. The calculator compares the financial impact of buying after financing, maintenance, taxes, insurance, and selling costs against renting and investing the down payment or cash-flow difference. The result helps estimate which option may be financially stronger over the selected analysis period.

When should you use this calculator?

Use this tool before buying a home, signing a long-term lease, comparing mortgage offers, testing early repayment, evaluating refinancing, or deciding whether to rent or buy a business asset. It is also useful for real estate analysts, finance educators, content creators, and advisors who want to explain the rent-versus-buy decision with numbers.

Rent vs Buy Calculator FAQ

Is buying always better than renting?

No. Buying can be better when property appreciation, equity building, and long-term ownership benefits exceed financing, maintenance, taxes, and opportunity costs. Renting can be better when property prices are high, mobility matters, or alternative investment returns are stronger.

Why does the calculator use NPV?

NPV converts future cash flows into today’s value. This makes the comparison more realistic because money today is not equal to money received or spent years later.

Why does alternative investment return matter?

The down payment and any monthly cash-flow difference could be invested elsewhere. Including this opportunity cost helps compare ownership against a realistic renting-and-investing scenario.

Can I use this for equipment or business assets?

Yes. The same logic can help compare renting, leasing, or buying an asset if you adjust the inputs to match the asset’s price, financing cost, maintenance, resale value, and usage period.
