How this calculator works
Rent cost includes escalating rent, inflation-adjusted renter insurance, and upfront rental costs, less a returned deposit when selected. Buy cost includes upfront cash, actual mortgage payments, property tax, insurance, HOA, maintenance, PMI, and selling costs, less net sale proceeds after the remaining mortgage.
The lower-upfront-cost side invests the initial difference. Each month, the lower recurring-cost side invests that cash-flow difference. Investment growth—not contributed principal—is subtracted from that side’s cash net cost, avoiding double counting. Positive returns are assumptions, not guarantees.
Insurance and HOA rise with general inflation; rent follows its own growth rate; property tax and maintenance follow projected home value. Potential tax deductions and utility differences are not included.

How to use the rent vs buy calculator
- 1
Choose a comparison period from 1 to 40 years.
- 2
Enter monthly rent, rent growth, renter insurance, deposit and renter fees.
- 3
Enter home price, down payment, mortgage rate and term.
- 4
Add property tax, insurance, HOA, maintenance, PMI, closing and selling costs.
- 5
Set appreciation, investment return and inflation assumptions, then review the yearly comparison and possible break-even point.
How the rent-versus-buy model works
The renting side adds rent, renter insurance and fees, then accounts for the deposit and any return of that deposit. The buying side models mortgage payments, property tax, home insurance, maintenance, HOA and PMI. It also tracks the mortgage balance and estimates owner equity after selling costs.
Upfront cash and any monthly cost difference can have an opportunity cost. The calculator models that difference at the investment-return rate entered. This helps avoid comparing rent only with the mortgage payment while ignoring the down payment, closing costs or possible investment growth.
Rent vs buy example
Consider seven years of $2,000 monthly rent and a $400,000 home with 20% down. Using a 6.5% 30-year mortgage, 3% annual rent growth, 3% home appreciation, 1.2% property tax, normal insurance and maintenance assumptions, 3% buying costs, 6% selling costs and a 5% investment return, the model estimates renting is lower by about $32,432 over seven years. It finds no break-even within that period.
This is an illustration, not a local market forecast. Small changes to appreciation, maintenance, transaction costs or the moving date can change the result.
What break-even means here
A break-even year is the point where the modeled financial advantage changes from one option to the other. It is not the month when mortgage principal is repaid, and it does not mean both choices fit your lifestyle equally well. Review the year-by-year table because a later sale date can produce a different answer.
Questions the numbers cannot answer
Buying can provide control, stability and exposure to property-price changes, but it also brings maintenance work, transaction costs and less flexibility. Renting can make moving easier and reduce repair responsibility, but rent may rise and the property remains under the owner’s control. Job plans, family needs, cash reserves and local housing quality deserve a separate review.
Important limitations
- No location database: the calculator does not look up local rent, tax, insurance or home-price data.
- Constant assumptions: growth and return rates are applied steadily even though real markets change.
- Tax treatment: deductions, capital-gains rules and local benefits are not modeled.
- Financing: adjustable rates, refinancing and missed payments are excluded.
- Estimate only: results are not financial, mortgage, tax or real-estate advice.
