Understanding Average Annual Return (AAR) in Multifamily Investing
When evaluating any investment, one of the most natural questions to ask is: “On average, how much did I make per year?” Average Annual Return (AAR) is the metric designed to answer exactly that. It’s a useful starting point — but like any single-number summary, it has important limitations that every investor should understand.
What is Average Annual Return (AAR)?
AAR is the arithmetic mean of an investment’s annual returns over a specified time period. It’s calculated by summing each year’s return and dividing by the number of years.
AAR Formula
AAR = Sum of Annual Returns ÷ Number of Years
Example: A 5-year investment returns 6%, 9%, 4%, 11%, and 10% in successive years. AAR = (6 + 9 + 4 + 11 + 10) ÷ 5 = 40 ÷ 5 = 8.0% average annual return
What AAR Tells You
AAR provides a quick, intuitive way to benchmark performance. It’s useful for:
- Comparing two investments across the same time period with roughly similar return volatility
- Communicating overall performance in a single, understandable figure
- Evaluating whether a deal is meeting broad return targets over time
What AAR Doesn't Tell You — Important Limitations
AAR has meaningful blind spots that investors should understand before relying on it:
It doesn’t account for the time value of money. AAR treats a return in Year 1 the same as an identical return in Year 5. IRR, by contrast, weights early returns more heavily.
It can be misleading with volatile returns. A 50% loss followed by a 50% gain produces a 0% AAR — but you have actually lost 25% of your capital. The geometric mean (or IRR) is a more accurate measure in such cases.
It doesn’t account for investment size or timing. AAR doesn’t tell you how much capital was at work at any given time, or how large the actual distributions were relative to your original investment.
How Fourth Wall Capital Uses AAR
In syndication reporting, we present AAR as a transparency measure — giving investors a simple year-over-year picture of how the deal is performing relative to projections. We use it alongside IRR (which captures the full time-weighted picture) and Cash on Cash Return (which reflects actual annual distributions). No single metric tells the complete story.
At Fourth Wall Capital, our underwriting uses all three metrics presented together, so investors can evaluate both the current income performance and the projected total return before making a commitment.
A Note on AAR Terminology
In real estate syndications, you may also see terms like ‘annualized return,’ ‘average annual cash-on-cash return,’ or ‘average annual equity return.’ These are related but distinct concepts. When reviewing any offering, always ask the sponsor to clarify exactly what is included in their return calculation — and whether it accounts for the timing of capital events.
