Understanding rent-versus-buy comparison — sensitivity table
Everyday editorial team · GEOINNOVATION CO., LTD · Published · Updated
What this calculation is for
A rent-versus-buy comparison begins by distinguishing recurring cash cost from wealth accumulation. Mortgage principal builds equity, whereas interest, tax and insurance are costs, so equal monthly outlays do not imply equal long-term outcomes.
How the method works
The recurring ownership amount combines mortgage principal and interest with entered tax and insurance. The tool separately shows a hypothetical property value at the end of the full mortgage term. The displayed model uses: Compare recurring rent with mortgage, tax and insurance; estimate equity from loan amortization and home-value change.
A worked example
For an illustrative rent-versus-buy comparison scenario, use Monthly rent: 2200 $; Home purchase price: 400000 $; Down payment: 20 %; Mortgage APR: 6.5 %; Mortgage term: 30 years; Annual property tax rate: 1.1 %; Annual home insurance: 1800 $; Annual home appreciation assumption: 2 %. The modeled monthly owner payment estimate is $2,539.28. These are example assumptions, not current prices, official benefit amounts or personalized advice.
Assumptions and real-world differences
This is not a complete net-worth comparison. Closing and sale costs, upkeep, rent increases, investment returns on unused cash, taxes and uncertain appreciation can change the outcome. Excludes local transaction costs, repairs, tax benefits, rent investments and market risk; not a purchase recommendation.
Reading the home purchase price sensitivity table
The tool evaluates the same model across a range of home purchase price values while holding other assumptions constant. Choose a realistic low value, high value and number of points. Each row reports the same headline measure; the table is a set of conditional calculations, not a probability distribution or a forecast. Input-step rounding can make nearby rows equal.

Sensitivity analysis: 5 comparison points
Home purchase price ranges from $200,000 to $600,000.
- Home purchase price: $200,000: $1,344.64
- Home purchase price: $300,000: $1,941.96
- Home purchase price: $400,000: $2,539.28
Frequently asked questions
- Does a lower owner payment prove buying is better?
- No. Upfront capital, flexibility, risk and costs omitted from the simplified comparison also matter.
- Which inputs should I check before using this rent-versus-buy comparison estimate?
- Check monthly rent, home purchase price, down payment, mortgage apr, mortgage term, annual property tax rate, annual home insurance, annual home appreciation assumption. Match each field’s unit and time period, then compare the detailed rows rather than treating the headline alone as the complete answer.
- Does the most favorable row show the most likely outcome?
- No. The table assigns no likelihood to any row. It shows how the result responds to the chosen assumption, and you remain responsible for selecting a plausible range.
