Rent Versus Monthly Ownership Cash Cost
Compare monthly cash outflow for renting and buying. Appreciation and the opportunity cost of down-payment cash are absent, so the result cannot determine which choice is financially better over the long term.

How to use this tool
Enter USD price, down percentage, annual rate, years, extra monthly cost and rent. The extra field is implemented as added taxes, insurance or association-style cost, not accelerated principal repayment.
Results and examples
Ownership cost adds the extra cost to mortgage principal and interest. Compare the monthly difference while separately recognising that the principal component may build equity rather than being pure expense.
Worked example
USD 120,000 price, 20% down and 0% for ten years gives USD 800 payments; adding USD 200 costs makes USD 1,000 monthly.
Limitations
- Resale value, transaction costs, opportunity cost and price changes are excluded.
- The extra-cost field does not reduce the loan balance.

Frequently asked questions
Does Extra payment mean prepayment here?
No. This implementation adds it to ownership cost rather than principal repayment.
Does a small difference mean buying wins?
Monthly cash flow alone cannot establish long-term value.
