Key CRE Investment Metrics: Cash-on-Cash, IRR, and Equity Multiple Explained

Cash-on-cash return, equity multiple, and IRR are the three most common metrics investors use to measure a CRE deal's performance, each capturing a different piece of how and when an investment pays back.

Once you understand NOI and cap rate, the next question is: what does this deal actually return to the investor. Cash-on-cash return, equity multiple, and internal rate of return (IRR) each answer that question from a slightly different angle, and none of them tells the whole story on its own.

While there are many metrics used to evaluate real estate returns, we'll briefly cover a few of the primary ones investors rely on: Cash-on-Cash (CoC), Equity Multiple (EM), and Internal Rate of Return (IRR).

Cash-on-Cash

Cash-on-Cash is the most basic of the three metrics to calculate. But because it only looks at a single year in isolation, it's the narrowest of the three, and you should understand its limits before relying on it too heavily. Annual cash flow here is NOI minus the property's annual debt service, so getting the loan payment right matters just as much as getting NOI right.

It's a simple, intuitive number, and it's useful for understanding near-term income. But it only looks at a single year, and it doesn't account for what happens at sale. A deal with a strong cash-on-cash return in year one could still turn out to be a poor overall investment if the eventual sale falls short.

Equity Multiple

Equity Multiple is a step up from Cash-on-Cash since it captures the full hold period rather than a single year. But total dollars returned only tells part of the story, it leaves out one key variable that IRR accounts for: Timing of cash flow.

Timing is a key metric that EM fails to capture. A 2.5x return over 3 years is a very different outcome than the same 2.5x over 10 years, even though the multiple looks identical either way. This is why Equity Multiple is best used alongside IRR, which does account for the timing of cash flows, rather than as a standalone metric.

Internal Rate of Return (IRR)

IRR is the most complete of the three metrics, because it accounts for both how much money came back and when it came back. This matters because a dollar today is worth more than a dollar five years from now, money received sooner can be reinvested sooner.

Here's a simple way to see why timing matters. In the above example, the second scenario has no return until year three, when the full $13,000 comes back at once. Both deals return the same total dollar amount, but the first deal has a higher IRR, because some of that money came back earlier and could have been put to work sooner.

The actual IRR calculation involves discounting a full stream of cash flows, which is a modeling exercise rather than something you'd do by hand. At this stage, the important thing is the intuition: IRR rewards cash flow that arrives sooner, not just cash flow that arrives eventually.

IRR also comes with a lesser known limitation to know at this stage: the calculation implicitly assumes that any interim cash flow gets reinvested at that same IRR rate going forward. In practice, that assumption is often unrealistic, an investor receiving distributions along the way isn't necessarily able to reinvest that cash at an equally attractive rate. This is one reason a high IRR shouldn't be treated as a complete measure of a deal's quality by itself, it's a useful metric, not the final word.

Why You Need More Than One Metric

Each of these metrics can mislead if you look at it alone. A high cash-on-cash return in year one says nothing about whether the property will sell well five years later. A strong equity multiple says nothing about whether the return was fast or painfully slow in coming. A high IRR can sometimes come from a small, easily won early return that doesn't reflect the deal's overall quality, or it can mask a return that's heavily backloaded and depends entirely on a future event, like a sale, actually happening as projected.

Sponsors and experienced investors look at all three together, alongside the underlying assumptions behind them, rather than anchoring on any single number. These same metrics come up again when comparing real estate returns directly against the stock market. That eventual sale price comes from the same valuation approaches covered in the next chapter.

A Quick Note on Hold Period

All three of these metrics only mean something in the context of a specific hold period and strategy. A core, stabilized deal targeting steady cash flow will look very different across these metrics than a value-add or opportunistic deal targeting appreciation. Neither is inherently better, they're just optimizing for different things, a distinction covered in more depth later in this series.

Common Mistakes

• Chasing the highest IRR without checking the assumptions behind it. An impressive IRR built on an aggressive exit cap rate or an unrealistic rent growth assumption isn't actually a better deal, it's a riskier projection.
• Comparing equity multiples across different hold periods as if they were equivalent. A 2x equity multiple over 3 years is a meaningfully better result than the same 2x over 10 years.
• Ignoring cash-on-cash return early in the hold period. For an investor who needs current income, a deal with a low cash-on-cash return in the early years might not fit, even if the projected IRR looks strong.
• Treating IRR as a complete measure of investment quality on its own. IRR's calculation assumes interim cash flows get reinvested at the same rate, an assumption that doesn't always hold up in practice, and it doesn't capture risk, leverage, or how a return was actually achieved.
