IRR and Cash-on-Cash Return: Two Ways to Measure Performance

Cash-on-cash return is the simplest income metric in real estate. It is the annual cash distribution you receive divided by the cash you invested. If you invest $10,000 and receive $600 in distributions over the year, your cash-on-cash return is 6%. It is intuitive, easy to calculate, and useful for comparing the income throw-off of different investments.

The limitation is that cash-on-cash ignores two things: the time value of money and the capital return at exit. It tells you about income, not about the total outcome. A property that pays 5% cash-on-cash for five years and then returns your capital with no gain has a very different total outcome from one that pays 5% and then returns your capital plus 40% appreciation — yet both show the same cash-on-cash figure.

IRR is a more complete measure. It is the annualised discount rate that makes the present value of all cash flows from an investment equal to the initial investment. In plain terms, it is the annualised total return that accounts for every cash flow — your initial investment (negative), each distribution (positive), and the final exit proceeds (positive) — and weights them by when they occur.

Because IRR incorporates the timing of cash flows, two investments with identical total cash returns can have different IRRs. An investment that returns $12,000 over three years has a higher IRR if the money comes back evenly ($4,000 a year) than if it all comes back at the end, because the even distribution lets you reinvest sooner.

Cash-on-cash is best when you want to know "how much income am I getting right now relative to my capital?" It is the metric for investors who depend on distributions to live on, or who want to compare the income-generating power of properties year to year.

IRR is best when you want to know "what is the annualised total return of this investment, accounting for income and capital and timing?" It is the metric for comparing the overall quality of investments with different hold periods, distribution profiles, and exit values. Institutional investors and fund managers use IRR as the primary yardstick for this reason.

Suppose you invest $10,000. Over a five-year hold you receive $500 a year in distributions (5% cash-on-cash each year). At the end of year five, the property is sold and you receive $12,000 — your original capital plus $2,000 of appreciation. Your total cash return is $4,500 ($2,500 of income + $2,000 of gain). Your IRR is approximately 7.8% — higher than the 5% cash-on-cash because it includes the capital gain and the time value of the distributions.

The IRR exceeds the cash-on-cash return whenever there is capital appreciation, and falls below it whenever there is capital loss. This is why IRR is the more honest measure of total performance — it captures the full economic outcome, not just the income slice.

Platforms often quote a projected or target IRR. This is a model output based on assumptions about rent, expenses, appreciation, and hold period. It is useful as a comparison tool, but it is not a promise. Actual IRR can only be calculated after the investment is fully realised — after the exit. Until then, any IRR figure is an estimate that will move as assumptions change.
