Housing
Rent vs Buy Calculator
Compare renting with buying a home over your stay: mortgage, home equity, ownership costs, the investment opportunity cost, and break-even.
How Rent vs Buy works
Start both paths with the same cash
The buyer spends the down payment and closing costs on the home. The renter invests that same cash instead.
Compare the costs month by month
Rent and renter's insurance against the mortgage payment, property tax, insurance, mortgage insurance, HOA, and maintenance. Whichever path costs less invests the difference.
Grow what changes
Rent rises, the home's value changes, and both investment accounts earn the return you assume, each at its annual rate applied month by month.
Compare where each path ends
The renter has the investments. The buyer has the home, sold at the end, minus the mortgage still owed and the selling costs, plus any investments.
What the comparison accounts for
Why the mortgage payment alone is not enough
Rent and a mortgage payment are not the same kind of cost. Part of each mortgage payment pays down the loan and stays yours as equity, while buying adds costs rent does not: taxes, insurance, upkeep, and the costs of buying and selling.
Home equity
Equity is the home's value minus the mortgage still owed. It grows as the loan is paid down and as the value rises, and shrinks if the value falls. Selling costs come out of it when the home is sold.
Opportunity cost and invested savings
Money spent on a down payment cannot be invested elsewhere. The calculator models this directly: the renter invests the upfront cash, and each month the cheaper path invests what it saves.
Home appreciation
How much the home's value changes each year. It is the assumption that moves the result most, and values can fall as well as rise.
Rent growth
Rent usually rises over time, which makes renting more expensive each year while a fixed-rate mortgage payment stays the same.
Maintenance and ownership costs
Owners pay property tax, insurance, HOA dues, and upkeep. Maintenance is modeled as a share of the home's estimated value, so it rises when the value does.
Buying and selling transaction costs
Closing costs at purchase and selling costs at the end are why buying usually starts behind: a home sold soon after it is bought loses both.
Break-even point
The first month at whose end buying's net position, as if the home were sold then, moves ahead of renting's. Short stays often end before it; it can also never come.
What the model does not include
- Tax deductions for mortgage interest or property tax, and taxes on investment gains or home sales
- Renovations and improvements, and any value they add
- Refinancing, adjustable rates, and paying the mortgage off early
- Rising property tax, insurance, or HOA dues
- Moving costs, security deposits, and differences between the homes
Example comparison
$2,000 a month in rent rising 3% a year, against a $400,000 home with $80,000 down at 6.5% over 30 years, $4,800 of property tax and $1,800 of insurance a year, $100 of HOA a month, 1% maintenance, 3% closing and 6% selling costs, 3% appreciation, and a 5% investment return. Calculated the same way as the calculator above.
After 7 years
- Renting position (investments)
- $210,802.97
- Home value
- $491,949.55
- Mortgage balance
- $289,331.75
- Selling costs
- $29,516.97
- Buying position (net home proceeds)
- $173,100.83
Renting is ahead by $37,702.14 under these assumptions.
How it starts
- Upfront cash
- $92,000.00
- Closing costs
- $12,000.00
- First month: renting
- $2,020.00
- First month: owning
- $3,005.95
- Break-even
- Buying ahead after 15 years, 1 month
At purchase, buying starts $36,000.00 behind: selling right away would lose the $12,000.00 of closing costs and $24,000.00 of selling costs. The break-even point shown is over a 20 years comparison.
| Stay | Renting position | Buying position | Ahead |
|---|---|---|---|
| 3 years | $141,857.69 | $102,330.27 | Renting |
| 7 years | $210,802.97 | $173,100.83 | Renting |
| 15 years | $353,723.87 | $353,607.19 | Even |
| 20 years | $451,793.58 | $510,390.18 | Buying |
Assumptions
- This is an educational comparison based on the values you enter. It is not a recommendation to rent or buy, and actual costs, returns, and home values will differ.
- Both paths start with the same cash: the down payment plus buying closing costs. The buyer spends it; the renter invests it.
- The mortgage payment, interest, and balance come from Calcora's amortization engine, as in the Mortgage Calculator. Closing costs are paid upfront and not financed.
- Property tax, homeowners insurance, and HOA are constant monthly equivalents (annual amounts ÷ 12). Mortgage insurance is the amount you enter, charged while there is a mortgage and never inferred from the down payment.
- Maintenance each month is the home's value at the start of the month × the maintenance rate ÷ 12, rounded to the cent.
- Rent growth, home appreciation, and investment returns are effective annual rates applied monthly: a value after m months is the starting value × (1 + rate)^(m ÷ 12). A year at 3% is exactly 3%.
- Each month, both investment accounts earn a month of the return first, then the path whose costs were lower invests the difference at the end of the month.
- Each net position assumes the home is sold at that point: home value − mortgage balance − selling costs + the buyer's investments, against the renter's investments. Selling costs are charged once, at the value at that time.
- Taxes on income, investment gains, or home sales, and tax deductions are not modeled.
