Cap Rate vs. IRR vs. Equity Multiple: What Passive Investors Really Need to Know

The Problem with Shiny Metrics

If you've looked at a real estate deal recently, you've probably seen all three of these metrics: Cap Rate, IRR, and Equity Multiple. They're plastered across investment decks, emails, and crowdfunding sites. But here’s the problem: not all of these numbers matter equally—especially for passive investors.

So, which one should you actually care about?

The truth is, each metric tells a different story. But without knowing what story you're hearing, you could be making a decision based on the wrong signals. Let’s break it down.

Cap Rate: A Snapshot, Not a Strategy

Cap rate, or capitalization rate, is a simple formula:

Cap Rate = Net Operating Income (NOI) / Purchase Price

It’s often used to evaluate how "cheap" or "expensive" a property is relative to its income. But here’s the catch: cap rate doesn’t account for debt, time, taxes, or capital improvements. It's just a snapshot—a single moment in time.

For passive investors, especially those investing in value-add or opportunistic deals, the cap rate on day one can be almost irrelevant. A 4.5% cap might seem low, but if the asset is being repositioned or re-tenanted, it could be generating a 17% IRR later on.

Infinity⁹ POV: We don’t dismiss cap rate—but we never mistake it for a full picture. A low cap rate doesn’t mean a bad deal. There are no bad markets, just bad strategies.

IRR: Timing Is Everything

IRR, or Internal Rate of Return, is the most widely quoted metric—and the most often misunderstood. IRR measures the average annual return with time value factored in. That’s important. Getting $50K back in year 2 is more valuable than in year 5, and IRR captures that.

The problem? IRR can be manipulated. Deals that return capital quickly (even if small amounts) can look better on paper than those that generate massive returns later.

For example, a deal that sells in year 2 might post a 20% IRR. But a deal that triples your money in year 7 might only show a 16% IRR—and still be the far better investment.

Infinity⁹ POV: We watch IRR, but we don’t chase it. When timing games distort long-term wealth building, we stay focused on the full journey.

Equity Multiple: The Real Wealth Builder

Equity Multiple = Total Cash Returned / Total Equity Invested

This one is simple, and that’s why it matters. Equity multiple tells you how much money you’re actually getting back—whether in 3 years or 10. A 2.0x multiple means you doubled your money. A 1.6x means you made 60% over the life of the investment.

Unlike IRR, it doesn’t care when the money comes. It’s pure output.

Why it matters: Equity multiple is the truest indicator of wealth creation. Passive investors aren’t day traders. You don’t need your return to look good next quarter—you need it to matter when you exit.

Infinity⁹ POV: Our focus is long-term value creation. Equity multiple aligns with how real wealth is built over time. We call it the Building Capital Framework.

Which Metric Matters Most?

It depends on your goals. But for passive investors seeking long-term real estate exposure with institutional-quality opportunities, equity multiple is often the most honest and useful measure.

Cap rate can guide you on asset type and risk profile. IRR can give insight into the efficiency of returns over time. But only equity multiple answers the fundamental question: "How much richer will I be when this ends?"

Real-World Example: Two Deals, Two Outcomes

Deal A

• Cap Rate: 6.0%
• IRR: 14%
• Equity Multiple: 1.5x

Deal B

• Cap Rate: 4.2%
• IRR: 16%
• Equity Multiple: 2.1x

Deal A has a higher cap rate but delivers less wealth. Deal B has a tighter entry yield, but because of strong value creation, delivers superior total returns. That’s the difference between a short-term yield play and long-term wealth strategy.

Final Takeaway

As a passive investor, don’t get distracted by the loudest metric. Cap rate is not destiny. IRR is not gospel. Focus on what really matters: How much wealth is this going to build—and how sound is the path to get there?

At Infinity⁹, we design deals with that question in mind. Your money doesn’t need a visa—and your future doesn’t need noise.
