How to Walk Through an LBO in an Interview

"Walk me through an LBO" shows up in almost every private equity interview and plenty of investment banking ones too. It looks intimidating the first time, mostly because there are a lot of moving pieces to hold in your head at once. Once you have worked through the mechanics a couple of times, though, the structure becomes predictable, and the question turns into one of the easier ones to answer well.

This guide covers the framework, a full worked example with real numbers, and the follow-up questions that tend to separate a strong answer from a memorized one.

What Is a Leveraged Buyout

A leveraged buyout is the purchase of a company using a large amount of borrowed money alongside a smaller amount of equity from the buyer, typically a private equity firm. The target company's own cash flows are what service and eventually repay that debt, which is why lenders care so much about how stable and predictable those cash flows are before they agree to finance the deal.

The private equity firm, often called the sponsor, holds the company for several years, usually somewhere in the five to seven year range, then sells it. The return the sponsor earns depends on how much the equity portion of the deal grew relative to what they originally put in.

The Four-Step Framework for Answering This Question

Interviewers want a clear, high-level answer first. Diving straight into modeling detail without being asked tends to read as nervousness rather than confidence, so it's worth keeping the first pass short and letting the interviewer pull you into whichever step they want to hear more about.

The four steps, in order, are:

1. Figure out the entry valuation, meaning how much the sponsor pays for the company, usually expressed as a multiple of EBITDA.
2. Build the sources and uses, which lays out how the deal gets financed. Uses include the purchase price and transaction fees. Sources include the new debt raised and the sponsor's equity check.
3. Project the company's free cash flow over the holding period and use it to pay down the debt raised in step two.
4. Model the exit, usually a sale at some multiple of EBITDA, repay whatever debt is left, and calculate the return on the sponsor's original equity.

A Worked Example

Numbers make this stick a lot better than the framework alone, so here is a simplified example using round figures.

Say the target company has $100M of EBITDA, and the sponsor agrees to pay an entry multiple of 8.0x. That puts the entry enterprise value at $800M. The deal gets financed with 60 percent debt and 40 percent equity, so the sponsor raises $480M of debt and contributes $320M of equity.

Over the next five years, assume EBITDA grows from $100M to $150M, and the company uses its excess cash flow to pay down $200M of the original debt, bringing the balance down to $280M at exit.

At exit, assume the company sells at the same 8.0x multiple it was bought at. Exit enterprise value comes out to $150M times 8.0x, or $1.2B. Subtract the $280M of remaining debt, and the equity is worth $920M at the time of sale.

The sponsor put in $320M and got back $920M, which works out to a multiple on invested capital of roughly 2.9x. Spread over a five year hold, that lands in the low-to-mid 20s for an annualized IRR.

Real models add complexity on top of this, including interest expense flowing back through the cash flow statement, taxes, working capital swings, and capital expenditures. The simplified version above is what most interviewers are actually listening for on a first pass, and it is worth being able to produce cleanly before adding those layers back in.

The Three Levers of Return

A common follow-up is some version of "how does a PE firm actually make money on a deal like this." There are three levers, and a strong answer names all three rather than just the first one that comes to mind.

The first is multiple expansion, meaning the company sells for a higher multiple than it was bought at. The second is EBITDA growth, whether from revenue growth, margin improvement, or both. The third is debt paydown, where the company's own cash flow retires debt over the holding period, which increases the sponsor's share of the enterprise value without the enterprise value itself needing to grow at all.

The example above deliberately held the exit multiple flat at 8.0x, which isolates the other two levers. It is worth seeing what happens without any leverage at all, since that is what actually explains why leverage amplifies returns rather than just being told that it does.

Imagine the same deal done with 100 percent equity and no debt. The sponsor puts in the full $800M, and since there's no debt to pay down or interest to service, that lever disappears entirely. At exit, the enterprise value has still grown to $1.2B from EBITDA growth, and with no debt to subtract, the equity is worth the full $1.2B. That's a multiple on invested capital of 1.5x, compared to the 2.9x from the levered version above.

The underlying business performs identically, EBITDA grows by the same amount, and the exit multiple does not change. The only difference is that in the levered deal, that growth and the debt paydown both accrued to a much smaller equity base, which is the entire mechanism behind why leverage magnifies equity returns.

What Makes a Good LBO Candidate

Interviewers sometimes flip the question around and ask what makes a company attractive as a buyout target in the first place. A few traits come up consistently.

Stable, predictable cash flow matters more than almost anything else, since that cash flow is what services the debt. A strong market position and defensible competitive advantages reduce the risk of that cash flow deteriorating during the hold. Low existing debt gives the sponsor room to layer in new leverage without the company being overextended. Opportunities for margin improvement or operational efficiency give the sponsor a clear path to grow EBITDA rather than relying purely on multiple expansion. Relatively low capital expenditure requirements help too, since heavy ongoing investment needs eat into the free cash flow that would otherwise go toward paying down debt.

Where Most People Lose Points

A few mistakes come up often enough that they're worth calling out directly. The first is naming only one or two of the three return levers instead of all three, usually leaving out debt paydown entirely. The second is being able to recite the four steps but not being able to explain why leverage amplifies returns when asked directly, which is exactly the kind of question that separates a memorized answer from an understood one. The third is mixing up enterprise value and equity value at entry or exit, which throws off every number that follows.

None of these require deep modeling skill to fix. They mostly come down to having walked through the mechanics enough times that the logic feels automatic instead of memorized.

Where to Go From Here

The framework above will get you through a first pass, but sounding genuinely comfortable with it under interview pressure takes repetition. Offcycle has LBO mechanics, along with the surrounding valuation and accounting concepts that tend to come up in the same conversation, built into structured flashcards you can work through by topic and difficulty.

Beyond flashcards, you get custom practice sets you can build around whatever you're weakest on, quizzes that test the same material a different way, and a readiness score that tracks your progress across accounting, valuation, DCF, M&A, and LBO topics so you know exactly where you stand before you walk into the room.
