Cash-on-Cash Return Calculator
What does the property actually return on the money you put in? This includes the mortgage, closing costs, and up-front repairs — the three things that quietly ruin an otherwise attractive deal.

What Is Cash-on-Cash Return?
Cash-on-cash return is the plainest measure of a rental deal: of the money you actually handed over, what percentage comes back to you in a year? Unlike cap rate, it counts your mortgage. Unlike total return, it counts only real cash — not equity you cannot spend.
Cash-on-cash = annual pre-tax cash flow ÷ total cash invested
cash flow = NOI − mortgage payments · cash invested = down payment + closing costs + up-front repairs
What Counts as a Good Return
| Range | Reading |
|---|---|
| Negative | The property costs you money monthly. Sometimes deliberate in a high-appreciation market, but it must be funded from somewhere. |
| 0–4% | Thin. You are doing landlord work for something close to a passive return. |
| 6–10% | The range most small residential investors target. |
| 12%+ | Check the assumptions. Usually a cheaper market, an older building, or an expense line that is too low. |
Why Leverage Cuts Both Ways
A mortgage shrinks the cash you invest, which can lift cash-on-cash return well above the cap rate — but only while the loan costs less than the property earns. When the interest rate rises above the cap rate, leverage starts working against you: each additional dollar borrowed reduces cash flow. That is why the same property can be a solid buy at one rate and a losing one at another, with nothing about the building having changed.
This calculator uses principal and interest only. Taxes and insurance belong in operating expenses — if your lender escrows them, be careful not to count them twice.
What It Leaves Out
- Principal paydown. Every payment builds equity that never appears in this number.
- Appreciation. Often the largest component of long-run return, and entirely absent here.
- Tax effects. Depreciation can shelter much of this cash flow — see the depreciation calculator.
- Capital expenditures. The roof is not in operating expenses, but it is coming.
