  1. 055You buy an office REIT unit at Rs 300. It pays Rs 21 a year and you sell it for Rs 330 after five years. What are the equity multiple and the IRR, and why can two investments with the same multiple have very different IRRs?Performance measurement and returnsCoreInvescoNew York · 2025

    Try it first

    Which is closest to the IRR?

    Show the worked solution

    The equity multiple is 1.45x and the IRR is about 8.7%. You get back five payments of Rs 21 and Rs 330 on sale, Rs 435 in all, on Rs 300 in. The IRR is the rate at which those flows are worth exactly Rs 300 today. The multiple counts rupees and ignores time, so the same Rs 435 received in one lump at year 10 is still 1.45x but only about 3.8% a year.

    What does each measure actually count?

    Lend a friend Rs 300 and get Rs 435 back. Whether it came back in five years or fifteen, you can say you made 1.45 times your money, but you would not call the two loans equally good. The equity multipleTotal cash received divided by cash invested. It counts rupees and ignores when they arrive. counts how many rupees come back; the IRR counts how fast they come back. Here total cash is 5 x 21 plus 330, Rs 435, and 435 over 300 is 1.45x.

    The REIT unit returns Rs 435 on Rs 300 through yearly payments and a sale at year 5, an IRR of 8.7%; the same Rs 435 in one payment at year 10 is still a 1.45x multiple but an IRR of only 3.8%.

    How do you get the IRR quickly in the room?

    Split it into income and growth. The payment of Rs 21 on Rs 300 is a 7% yield. The price rises from 300 to 330, 10% in five years, which compounds to just under 2% a year. Add them and you are near 9%; the exact answer is a little lower, 8.7%, because the price gain arrives only at the end. Then offer the check: at 8.7% the five payments and the sale discount back to Rs 300.

    The relationship
    300=∑t=1521(1+r)t+330(1+r)5  ⇒  r≈8.7%300 = \sum_{t=1}^{5} \frac{21}{(1+r)^t} + \frac{330}{(1+r)^5} \;\Rightarrow\; r \approx 8.7\%

    330the sale price at year 5
    rthe IRR, the rate that makes both sides equal
    What it says in wordsThe IRR is the one discount rate at which everything you receive is worth exactly what you paid.

    Now the comparison the interviewer wants. The same Rs 435 in a single payment at year 5 is 7.7% a year, lower than 8.7% only because the distributions no longer arrive early. At year 10 it is 3.8%. The limit of IRR: it assumes the early cash can be reinvested at the same rate, and it says nothing about size, so a 20% IRR on Rs 1 lakh for one month is not better than 9% on Rs 1 crore for five years.

    Where candidates lose it

    The common slip is 9%: dividing the 45% total gain by five years. That treats the money as if it all came back evenly and ignores that the sale arrives last.

    The second loss is quoting only one of the two measures. Real estate and REIT desks ask for both because each hides what the other shows: the multiple hides time, the IRR hides size.

    What the interviewer asks next

    • The sale price is Rs 300 instead of Rs 330. What is the IRR?
    • Why do private real estate funds report both IRR and multiple to their investors?
    • The distribution is cut to Rs 15 in years 3 to 5. Which moves more, the multiple or the IRR?
