Cash-on-cash return is the number that tells you what your actual dollars earn in a rental deal. It is more honest than cap rate for anyone using a loan, and it is easy to game by accident. Here is how to calculate it, what counts as a good number in 2026, and the mistakes that quietly make a mediocre deal look great.
In 2026, many buy-and-hold investors aim for a cash-on-cash return of 8% or higher. But "good" depends on your market and your alternatives. A 6% return in a stable, appreciating market can beat a 12% return in a declining one. Always compare it to what your money could earn elsewhere.
The formula is simple:
Cash-on-cash return = annual pre-tax cash flow ÷ total cash invested
Annual cash flow is your monthly cash flow, after every expense and the mortgage, multiplied by twelve. Total cash invested is every dollar you put in to acquire the property: down payment, closing costs, upfront repairs, and any reserves you had to bring. If you put in $60,000 and the property pays you $4,800 a year, your cash-on-cash return is 8%.
Cap rate ignores the loan. It divides the property's income by its price, which is useful for comparing two buildings but tells you nothing about what you earn once financing is involved. Cash-on-cash return uses the actual cash you invested and the actual cash flow after the mortgage, so it reflects your real return. If you are borrowing to buy, cash-on-cash is the number to watch.
| Cash-on-cash | Read |
|---|---|
| Below 0% | You are paying every month to own it. Only makes sense as an appreciation bet, which is risky. |
| 0% to 5% | Thin. One repair or one vacant month can erase the year. |
| 5% to 8% | Positive but below target. Workable in a strong appreciation market, weak as a pure cash-flow play. |
| 8% to 12% | The target band for buy-and-hold rentals today. 8% is the line to clear. |
| 12% or higher | Strong, if the numbers are honest. Double-check that expenses are fully loaded. |
These are the same bands the cash-on-cash calculator reads against, and 8% is the target the DealGauge walk-away price solves for, so the guide and the tools agree on where the line sits.
A high cash-on-cash return is only meaningful if the inputs are real. Three common errors make it look better than it is:
Pre-tax cash-on-cash is the standard, but depreciation can shelter some of a rental's income, so your after-tax return can be higher than the pre-tax figure, but only if you are able to use the loss, and the passive activity rules limit who can. Whether they apply to you depends on your income and your level of participation, which is a question for an accountant, not a website. It is worth modeling both.
The free DealGauge calculator computes cash-on-cash, cash flow, DSCR, and a full A-to-F grade, with every expense loaded by default so the number is honest.

For most buy-and-hold rentals in 2026, yes, 8% is a solid target. Whether it is good for you depends on your market and what else you could do with the money.
Cash-on-cash looks only at annual cash flow versus cash invested. A full return on investment, and its time-weighted cousin IRR, also includes appreciation, loan paydown, and the eventual sale, so it captures the whole hold, not just this year.
Yes. The cash flow in the formula is after the mortgage payment and all operating expenses, which is exactly why it reflects your real return on a financed deal.
Cap rate ignores financing and divides income by price. Cash-on-cash uses your actual cash invested and cash flow after the loan. For a related walkthrough, see our guide on how to know if a rental is a good deal.
