Compare the long-term costs of renting versus buying a home.

How it works (Formula)
Net Buy Cost = Total Paid + Taxes + Maint + HOA - Equity Built; Compare to Total Rent Paid What Is the Rent vs Buy Calculator?
The Rent vs Buy Calculator is a comprehensive financial simulator designed to help you answer the ultimate real estate question: Should you continue renting or invest in a home? It compares the cumulative costs of renting (including insurance and rent inflation) against the net costs of buying (including maintenance, taxes, and equity growth).
What makes the Nuumra version better is our "Equity Factor" integration. We don't just look at monthly outgoings; we calculate the future value of your home and your principal paydown to determine your net wealth in both scenarios, providing a clear break-even year.
How to Use the Rent vs Buy Calculator
- Monthly Rent — Enter your current or expected base monthly rent.
- Annual Rent Increase — Estimate how much your rent will rise each year (typically 3-5%).
- Home Price — Enter the purchase price of the property you are considering buying.
- Home Appreciation — Estimate the annual increase in the home's market value.
- Years of Scenario — Choose how many years you plan to stay in the home or the rental.
- Click Compare — Press the button to see which option builds more wealth for you over time.
How the Rent vs Buy Formula Works
Our comparison uses two distinct financial tracks:
Net Buying Cost = (PITI + Maintenance + Selling Costs) − (Home Value Appreciation + Equity Built)
Net Renting Cost = Cumulative Rent + Cumulative Renters Insurance
Net Renting Cost = Cumulative Rent + Cumulative Renters Insurance
- Equity Built — The portion of your mortgage payment that goes toward principal.
- Appreciation — The increase in the property's value over your planned tenure.
- Break-even Year — The point in time when the wealth built by owning exceeds the savings from renting.
Understanding Your Rent vs Buy Results
Once you hit Compare, here is what each result means:
- Total Rent Paid — The absolute total amount of money handed to a landlord over your selected years.
- Total Buying Costs — The gross sum of payments, taxes, and repairs you will pay as an owner.
- Equity Built — Your "profit" at the end: the value of the home minus the remaining mortgage balance.
- Net Cost of Buying — The true financial "hit" of owning after accounting for the value you've created.
Tips to Get the Most Out of the Rent vs Buy Calculator
- Length of Stay is Key — If you plan to move in under 5 years, renting is almost always cheaper due to upfront closing costs.
- Factor in Maintenance — Homeowners spend roughly 1% of the home's value annually on repairs; don't leave this out!
- Tax Benefits — Depending on your income, mortgage interest deductions might make buying even more attractive than shown.
- Consider the "Opportunity Cost" — Remember that the down payment money could have been invested in stocks if you chose to rent.
Frequently Asked Questions
Is it better to rent or buy?
Buying is generally better if you stay for 5+ years, as equity building outweighs the high transaction costs of real estate.
What are the hidden costs of buying?
Hidden costs include property taxes, homeowners insurance, and annual maintenance/repairs (est. 1% of home value).
Does renting build equity?
No. Renting is a service expense; 100% of your payment is consumed with zero return on principal or ownership.
What is the price-to-rent ratio?
It's the home price divided by annual rent. Ratios over 20 usually favor renting; under 15 usually favor buying.
How does appreciation affect the choice?
Even 3% annual appreciation significantly boosts the "buy" case by building tax-free wealth in your primary residence.
What if I move in just 2 years?
In a 2-year window, the 3-5% costs to buy and 6% costs to sell almost always make renting the cheaper financial option.
