How the Rent vs Buy Calculator Works
This calculator compares the long-term cost of renting against buying the same home, factoring in your rent, the purchase price, down payment, rate, taxes, insurance, PMI, maintenance, and the appreciation you expect. It reveals the break-even point—how long you must stay for buying to beat renting.
The Core Comparison
Renting net cost = Total rent paid − growth of the invested down payment and monthly savings (compounded at your Investment Return %)
Buying net cost = Mortgage + taxes + insurance + maintenance − equity built − appreciation
Renting Scenario
Frequently Asked Questions
Typically, you need to stay in a home for 5-7 years to break even on closing costs and real estate agent fees. Closing costs to buy are usually 2-5% of the home price, and selling costs are 6-8%. The longer you stay, the more buying makes sense compared to renting.
Beyond your mortgage payment, homeownership costs include property taxes, homeowners insurance, maintenance and repairs (budget 1-3% of home value annually), HOA fees, utilities, and potential special assessments. These can add 20-30% to your monthly housing costs.
No, renting is not throwing away money. Renting provides flexibility, predictable costs, and no maintenance responsibilities. You can invest the money you would have spent on homeownership costs. The key is to compare total costs and consider your personal situation and goals.
The 5% rule suggests that if annual rent is less than 5% of the home's value, renting may be better. Conversely, if annual rent exceeds 5% of the home's value, buying may be better. For example, if a home costs $400,000, 5% is $20,000/year or $1,667/month.
Key Factors That Tip the Scale
- Time horizon: buying usually wins after 4–7 years; shorter stays favor renting.
- Appreciation: in rising markets, equity growth makes buying pull ahead faster.
- Rate and taxes: high carrying costs lengthen the break-even.
Hidden Costs of Buying
Maintenance (often ~1% of home value yearly), HOA fees, and transaction costs when you sell (roughly 6–8%) can erode the rent-vs-buy math if you move soon. The calculator includes these so the comparison is honest.
Frequently Asked Questions
Is buying always better long term?
Usually if you stay long enough and the market is stable-to-rising, but not for short stays or volatile markets. Run your numbers.
What if I invest the money I'd use for a down payment instead?
The calculator can model renting plus investing the down payment, which sometimes beats buying in weak-appreciation areas.
How do I estimate appreciation?
Use conservative local historical averages; avoid optimistic guesses. Your state guide gives market context.
