The Rent vs. Buy Projector
Determine the exact point where buying outpaces renting. Factor in unrecoverable "sunk costs," opportunity costs, and home appreciation to find your break-even year.

How the Rent Vs Buy Projector Works
This calculator compares the total cost of renting versus buying a home over your chosen time horizon. It factors in mortgage payments, property taxes, insurance, maintenance costs, closing costs, and expected home price appreciation.
Frequently Asked Questions
What costs are included in the buy scenario?
The calculator includes mortgage principal and interest, property taxes, homeowners insurance, HOA fees, maintenance (estimated at 1% of home value annually), and closing costs.
What costs are included in the rent scenario?
The calculator includes monthly rent payments, renters insurance, and assumes rent increases at the rate you specify.
Is buying always better long-term?
Not necessarily. Buying is typically better if you stay in the home for 5+ years. For shorter time horizons, renting often makes more financial sense due to transaction costs.
The Math Behind Rent vs. Buy
The ultimate financial debate usually hinges on emotion, but the reality is pure mathematics. When you rent, your "sunk cost" is 100% of your rent payment plus renter's insurance. When you buy, your sunk costs include mortgage interest, property taxes (usually around 1.2%), maintenance (1%), and homeowners insurance—none of which build equity.
The Break-Even Year is the exact point where the net worth you build through home equity outpaces the net worth you would have built by renting and investing your down payment (and any monthly savings) in the market. Our 2026 hypothesis holds that at a 6% interest rate, buying typically begins to outperform renting mathematically around year 7 in most markets.
Evaluating Opportunity Cost
The opportunity cost of buying a home is the return you could have earned if you invested your down payment in a diversified portfolio Instead of locking it up in home equity. If your alternative investment return is historically 7%, your home needs to appreciate significantly to overcome that hurdle rate, especially factoring in selling costs (typically 6%).
As the Projector highlights: Buying is fundamentally a strategy for long-term stability, hedging against rent inflation. Renting is a strategy for liquidity, allowing capital to remain aggressively invested elsewhere.
Frequently Asked Questions
What is the 2026 ownership premium?
The ownership premium refers to the additional unrecoverable costs of buying (interest, taxes, maintenance, insurance) compared to renting. In 2026, with elevated mortgage rates, this premium is historically high in the short term.
Is rent really 'throwing money away'?
No. Rent is the maximum you will pay for housing each month; a mortgage is the minimum. Renting provides a fixed cost and liquidity, allowing you to invest your down payment elsewhere for potentially higher returns.
How does the wizard calculate the break-even point?
We project 30 years into the future. For buying, we chart home value appreciation minus the mortgage balance and future selling costs. For renting, we compound your initial down payment plus any monthly cash-flow savings at your chosen investment return rate. The break-even is when the buying net worth exceeds the renting net worth.
Methodology
How this rent vs buy calculator works
This calculator uses rent, home price, mortgage assumptions, taxes, maintenance, and time horizon to estimate a rough cost comparison between renting and buying. It is designed for quick planning, comparison, and gut-checking, not for personalized financial advice.
Inputs to check
Use current balances, rates, fees, and monthly cash-flow numbers. Small changes in APR, APY, payment size, or time horizon can change the result meaningfully.
What the result means
Treat the output as a planning estimate. It can show tradeoffs clearly, but it cannot predict provider approvals, market returns, future rates, taxes, or policy changes.
Best use
Use it before assuming a house is automatically cheaper or more expensive than renting. Always compare the result against current provider disclosures before applying, switching, refinancing, or moving money.
Common questions
Is this calculator exact? No. It estimates based on the assumptions you enter. Actual results can differ because of fees, rate changes, taxes, payment timing, provider rules, or market performance.
How often should I update the numbers? Re-run the calculator whenever your rate, payment, income, balance, or goal changes. For rate-sensitive products, check the provider page the same day you make a decision.
