Hurdle Rate vs Internal Rate of Return: Key Differences Explained

One is a promise and the other is a measurement. The table compares them on definition, who sets each, who uses it, legal and tax treatment, risk, liquidity and a typical example.

ILPA, a trade body for fund investors, defines the two terms together. Its glossary calls the preferred return “the internal rate of return that a fund must achieve” before the manager gets a larger share (ILPA Principles 3.0). So the hurdle is, by definition, an IRR target. Some agreements use a simpler formula, ILPA’s 2021 report notes. In the IRR version, each contribution grows at the hurdle rate from the day it was paid in. Investors must receive that grown amount before any carried interest is paid.

Time matters as much as profit. Take an illustrative $1,000,000 investment that returns $1,400,000, a 1.4x multiple. The hurdle is 8% a year and compounds. Here is the same profit over two holding periods:

• Sold after 5 yearsIRR 7.0%. The hurdle needs $1,469,328. The fund falls $69,328 short, so no carry is paid.
• Sold after 3 yearsIRR 11.9%. The hurdle needs $1,259,712. The fund clears it by $140,288, and carry is paid.

How much carry depends on what follows the hurdle in the distribution waterfall, the order in which a fund pays out. With 20% carry, the three-year case gives two very different answers:

• Hard hurdleCarry applies only to profit above the hurdle: 20% × $140,288 = $28,058.
• Soft hurdle with a full catch-upAfter the hurdle, the manager receives the next $64,928 in a catch-up. That restores it to 20% of all profit: $80,000.

ILPA recommends the hard version, where carry comes only from profit above the preferred return. With a full catch-up, a strong result ends at the full carry share anyway. In that case the hurdle changes when the manager is paid. It changes how much only when the IRR lands near the hurdle.

Outside funds, the same pair drives project decisions. A company sets a hurdle rate, the minimum return a project must offer. It then estimates the project’s IRR from its expected costs and income. ILPA’s glossary puts the rule plainly: if the expected return is below the hurdle rate, the project is often not undertaken (ILPA Principles 3.0).

The logic is the same in both settings. The hurdle is the bar, decided first. IRR is the estimate or the result, compared with the bar. The difference is what happens next. A company skips a project that falls short. A fund that falls short pays all its profit to investors and no carry to the manager.

Working out an IRR yourself, by hand or on a calculator, is covered in how to calculate IRR.

Because the hurdle is an IRR test, anything that changes IRR changes the test. Three things matter most, and none of them adds profit.

• Speed of salesThe same multiple earned faster gives a higher IRR, as the example above shows.
• Credit linesA subscription credit line is a loan a fund uses before it calls your money. It shortens the time your money is invested, which lifts IRR. ILPA found that 98% of funds in one sample could put such a loan in place.
• The start dateIf the hurdle starts counting only when capital is called, a credit line delays the clock. ILPA says the hurdle should count from the date capital is at risk, which includes the day the loan is drawn.

ILPA also says credit lines should not be used chiefly to raise reported IRR and speed up carry. It suggests limits, such as loans outstanding for no more than 180 days (ILPA Principles 3.0). In ILPA’s model agreement, the preferred return keeps accruing until all capital and the unpaid preferred return are paid back (ILPA Model LPA).

Neither number is taxed on its own. IRR is a measure, so it creates no tax at all. The hurdle is a contract term that decides who gets which part of the profit. Each share is then taxed by its own rules.

For you as an investor in a US fund taxed as a partnership, the preferred return is part of your share of fund profit. It is taxed as what it is made of, such as capital gain, dividends or interest. You see it on your Schedule K-1, the yearly tax form a partnership sends its partners.

For the manager, the hurdle decides when carry starts. Under Section 1061, gain on carry counts as long-term only if the asset was held more than three years. Otherwise it is short-term (26 U.S.C. §1061). The policy debate is covered in the carried interest loophole.

They do different jobs, so you need both. For an investor, the hurdle is protection and IRR is the scorecard. For an employee of the fund manager, the hurdle is the bar to clear before carry pays out. That carry is often shared with the team. Both sides of a fund are explained in general partner vs limited partner.

Hurdle Rate

For

It gives investors the first slice of profit before the manager shares. A hard hurdle keeps that slice for good. Its terms are fixed in writing before you invest.

Against

It protects only modest results. A full catch-up gives the gap back in a strong fund. A late start date or a credit line can weaken it.

Verdict: the hurdle is a contract term worth reading closely. Check the rate, whether it compounds, when it starts counting and whether a catch-up follows. Those four details decide what 8% really protects.

Internal Rate of Return

For

It captures both profit and time in one yearly rate. It is the standard measure for private funds and the basis of the hurdle test.

Against

It can rise without more profit, through faster timing or a credit line. Part of it can be a valuation. It says nothing about how much money came back.

Verdict: IRR is the measure of speed. Read it net of fees, with and without the credit line, and next to a multiple such as TVPI.

Before you commit, find the hurdle in the partnership agreement. Note four things: the rate, whether it compounds, the date it starts and whether a catch-up follows. Then read the fund’s reported IRR. Ask for it net of fees, both with and without the credit line.

A single-deal SPV, a company set up to hold one investment, may or may not have a hurdle. On Axevil, carry and any hurdle are set per deal and written in that SPV’s documents. How SPVs work is explained in SPV investing. For the gap between a fund’s IRR and its spreadsheet version, see IRR vs XIRR.

Common Mistakes

• Treating the hurdle as a forecastAn 8% hurdle says nothing about what the fund will earn. It only sets who is paid first.
• Ignoring the catch-upWith a full catch-up, a strong fund pays the manager its full share. The hurdle mostly matters near 8%.
• Comparing gross IRR with the hurdleThe hurdle is tested on investors’ money, after fees. Compare it with net IRR.
• Missing the start dateA hurdle that starts at the capital call protects less when the fund borrows first.
• Reading IRR without a multipleA quick small gain can clear the hurdle. Check how much money came back too.

Hurdle rate

The minimum return investors must earn before the manager receives carry. In a company, the minimum return a project must offer.

Preferred return

The fund name for the hurdle: the return investors receive first, often 8% a year.

IRR (internal rate of return)

The yearly rate at which the present value of all cash flows in and out equals zero.

Carried interest

The manager’s share of a fund’s profit, often 20%, paid after the hurdle.

Hard hurdle

A hurdle after which carry applies only to profit above it.

Catch-up

The step after the hurdle in which the manager receives most or all payouts until it holds its full carry share.

Distribution waterfall

The order in which a fund pays out proceeds: capital, preferred return, catch-up, then the split.

Subscription credit line

A loan a fund draws on before it calls investors’ money.

Compounding

Adding each year’s return to the base, so the next year’s return is earned on a larger amount.
