Rent vs Buy Calculator
Should you rent or buy? Compare total costs over time - mortgage, taxes, appreciation, and opportunity cost - to find your break-even.
Understanding Rent vs Buy
When renting makes financial sense
Renting can be the smarter choice when you plan to move within 5–7 years, when home prices are high relative to rents, or when investment returns significantly outpace appreciation. High transaction costs — closing costs (2–5%) at purchase and agent commission (5–6%) at sale — can take years to recover. If your break-even point is beyond your expected stay, renting lets you stay flexible and invest the difference.
The hidden costs of homeownership
Mortgage payments are just the start. Property tax, insurance, HOA fees, and maintenance (typically 1% of home value per year) add significantly to your total cost. A $425,000 home with 1% maintenance means $4,250/year before any repairs. Closing costs at purchase (2–5%) and selling costs (5–6% agent commission) can erase years of equity gains.
The opportunity cost argument
A 20% down payment on a $425,000 home is $85,000, and closing costs add even more upfront cash. Renting can leave that money invested, plus any yearly cash-flow savings when ownership costs more than rent. This opportunity cost — what you forgo by tying up cash in a home — is a real cost of buying.
How appreciation changes the math
Higher appreciation tilts the scales toward buying, since the home's value compounds over time while the loan balance declines. At 3% appreciation, a $425K home is worth roughly $1M in 30 years. At 5%, it's $1.84M. Small differences in appreciation rates create large swings in the break-even point and total cost.

How to use the Rent vs Buy Calculator
The Rent vs Buy Calculator helps you make a quick estimate, compare scenarios, and understand the numbers behind the result. It is designed for fast planning, with enough context to make the answer useful instead of just a number.
- Enter the amounts, rates, and time period that match the scenario you want to model.
- Review the main result first, then scan the supporting totals to understand what drives it.
- Change one input at a time to compare payments, interest, growth, savings, or break-even points.
Method
How this calculator works
It uses equal spending budgets and invests either household's annual savings. Net cost subtracts investment earnings, not contributions; buying also subtracts sale proceeds after debt and selling costs. Tax benefit is a manual assumption, defaults to zero, and is not an eligibility calculation.
This calculator is useful for estimating the break-even point between renting and buying.
Because assumptions matter, try a few values that represent optimistic, typical, and conservative cases.
Financial results are estimates. Actual loan terms, taxes, fees, rates, and market returns can change the final outcome.
Example
Worked example
For a deliberately simplified $100,000 all-cash home, $12,000 yearly property tax, $500 monthly rent and 8% home appreciation, with all other expenses, transaction costs, rent growth, inflation, tax benefits and investment returns set to zero, year-one buyer wealth is $108,000.00 and renter wealth is $106,000.00. The renter saves the $6,000 spending difference. Buying leads by $2,000.00 in this accounting example, not in every scenario. It is not a housing forecast.
FAQ
Common questions
Is renting just throwing money away?
No. Rent buys housing the same way mortgage interest, property tax, insurance, and maintenance do — none of those build equity either. Buying wins when appreciation plus principal paydown outpace those costs and what your down payment could have earned invested elsewhere.
How long do I need to stay for buying to beat renting?
There is no universal period. Break-even is the first modeled year buying is ahead under your assumptions. The paths can cross again, so compare later horizons too.
What do people forget when comparing renting and buying?
Maintenance (often estimated at 1% of home value per year), the opportunity cost of the down payment, and transaction costs at sale. Including them frequently moves the break-even by years compared to a naive rent-versus-mortgage-payment comparison.
What information do I need for the Rent vs Buy?
You usually need home price, rent, mortgage terms, taxes, insurance, maintenance, appreciation, and investment return. You can change the inputs and recalculate as many times as needed.
How does the Rent vs Buy calculate the result?
It uses equal spending budgets and invests either household's annual savings. Net cost subtracts investment earnings, not contributions; buying also subtracts sale proceeds after debt and selling costs. Tax benefit is a manual assumption, defaults to zero, and is not an eligibility calculation.
Are the results exact?
Financial results are estimates. Actual loan terms, taxes, fees, rates, and market returns can change the final outcome.
