Hurdle Rate
It's the 'pass/fail' bar for an investment. If a project can't beat the hurdle rate, you don't do it. In PE, it's the return LPs get first before the fund managers take their cut.
Definition
A hurdle rate is the minimum acceptable rate of return a company or investor requires before committing capital to a project or investment. In corporate finance it is usually set at or above the firm's WACC, and a project is only approved if its expected IRR exceeds the hurdle. In private equity the term has a second, distinct meaning: the preferred return LPs must receive before the GP earns carried interest.
Formula
Decision rule: Invest if Project IRR > Hurdle Rate Corporate hurdle rate = WACC + Risk Premium PE preferred return = LP Capital x Hurdle Rate (typically 8%)
WACC
Weighted average cost of capital — the firm's blended cost of financing, the floor for any hurdle
Risk Premium
Extra return added for projects riskier than the firm's average (e.g. new geography, new product)
Project IRR
The expected internal rate of return of the specific project being evaluated
8% (PE context)
The standard preferred return LPs earn before GP carried interest kicks in
How the Hurdle Rate Drives Capital Allocation
The hurdle rate is the central screening tool in capital budgeting. When a company evaluates competing projects, it discounts each project's cash flows at the hurdle rate to compute NPV, or compares each project's IRR against the hurdle. Projects that clear the bar create value; projects below it destroy it. Because capital is finite, firms rank approved projects and fund the highest-return ones first. The most common starting point for the hurdle is the firm's WACC, since that is the blended cost of the capital being deployed — earning less than WACC means the project doesn't even cover financing costs.
Why Risk Premiums Get Added
Using a single WACC-based hurdle for every project ignores that projects differ in risk. A mature company's WACC might be 9%, but a speculative new-market expansion carries far more uncertainty. Finance teams add a risk premium — pushing the hurdle to, say, 13-15% — so risky projects must clear a higher bar to compensate for the chance of failure. Conversely, low-risk cost-saving projects might use a hurdle close to WACC. The principle mirrors the logic behind beta in the cost of equity: higher systematic risk demands higher required return.
The Private Equity Meaning: Preferred Return
In a PE fund, the hurdle rate (also called the preferred return or 'pref') is the minimum annualized return LPs must receive before the general partner earns carried interest. The market standard is roughly 8%. Below the hurdle, 100% of profits flow to LPs. Once the hurdle is met, a GP catch-up provision often lets the GP collect carry, after which profits split per the carry agreement (commonly 80/20). This structure protects LPs by ensuring managers only earn outsized incentive fees after delivering a baseline return — closely tied to the fund's IRR vs MOIC performance.
Worked Example — With Real Numbers
A company has a WACC of 9% and adds a 4% risk premium for an unproven product line, setting the project hurdle rate at 13%. The project is expected to generate an IRR of 11%. Because 11% < 13%, the project is rejected — even though 11% exceeds WACC — because it doesn't compensate for the added risk. Separately, in a PE fund with an 8% hurdle and a $100M LP commitment, the fund must return more than 8% annually before the GP collects any carried interest; the first ~$8M/year of profit goes entirely to LPs.
Key Takeaways
In corporate finance, the hurdle rate is the minimum return a project must clear — usually WACC plus a risk premium
A project is approved only if its IRR exceeds the hurdle rate (equivalently, if NPV at the hurdle rate is positive)
In private equity, the hurdle rate (preferred return) is the ~8% LPs must receive before the GP earns carry
Higher-risk projects get a higher hurdle rate; using a single firm-wide rate for everything is a classic mistake
Setting the hurdle too high causes a firm to reject value-creating projects; too low destroys value
Common Mistakes in Interviews
Confusing the corporate hurdle rate (project approval threshold) with the PE preferred return (LP return before carry) — they are different concepts that share the name
Applying one firm-wide hurdle rate to projects of very different risk profiles instead of risk-adjusting
Saying the hurdle rate is always exactly WACC — it is the floor, but firms add a cushion above WACC
Forgetting that 'IRR > hurdle rate' and 'NPV > 0 at the hurdle rate' are the same decision when discounting at the hurdle
How Interviewers Test This
A common question is 'What's a hurdle rate and how does it relate to WACC?' — answer that it's the minimum required return, with WACC as the floor plus a risk premium. In a PE interview, expect 'What's the hurdle in a fund's waterfall?' — explain the ~8% preferred return and GP catch-up. Knowing both meanings signals you understand corporate finance AND fund economics.
