LBO Explained Simply: A Complete Guide for Interview Prep
Learn how Leveraged Buyouts work with our simple guide. Understand the LBO structure, return drivers, and key formulas for your PE interviews.
A Leveraged Buyout (LBO) is the foundation of private equity investing. If you're preparing for PE interviews, understanding LBOs cold is non-negotiable. This guide breaks down everything you need to know, with interactive practice.
What is an LBO?
Note
An LBO (Leveraged Buyout) is when a company is acquired using a significant amount of borrowed money (debt). The target company's assets and cash flows are used to secure and repay the debt.
In a typical LBO:
- A private equity firm acquires a company
- The acquisition is funded with 60-70% debt and 30-40% equity
- The target company's cash flows service the debt
- The goal is to generate high returns on the equity invested
Why Use Leverage?
The magic of LBOs is that leverage amplifies returns. Let's see this in action:
A company is bought for $100M with $60M of debt and $40M of equity. Cash flow repays all of the debt during the hold, and the company is sold for $150M with no debt outstanding. What's the equity MOIC?
The Power of Leverage
Leverage transforms a 1.5x enterprise value return into a 3.75x equity return. This is why private equity firms can generate 20-30% IRRs even with modest operational improvements.
Sources & Uses
Every LBO starts with Sources & Uses, how you're financing the transaction. Understanding this framework is critical for PE interviews.
Total Sources = Total UsesThe Sources & Uses table shows where money comes from (debt + equity) and where it goes (purchase price + fees).
A PE firm buys a company for 10x EBITDA of $35M on a cash-free, debt-free basis. Transaction fees are $10M and the deal uses 6.0x EBITDA of new debt. What's the equity check?
The 3 Drivers of LBO Returns
LBO returns come from three sources: operational improvement (EBITDA growth), multiple expansion, and leverage/debt paydown. Understanding their relative importance is crucial.
Which typically contributes MOST to LBO returns?
3 Drivers of LBO Returns
| Term | Definition | Note |
|---|---|---|
| EBITDA Growth | Revenue growth and margin improvement | Usually the largest driver in today's deals |
| Debt Paydown | Cash flow retires debt, so more of the EV belongs to equity | Larger in very cash-generative businesses |
| Multiple Expansion | Selling at a higher multiple than you paid | A bonus, never the base case |
Calculating Exit Value
The exit is where you realize returns. Understanding how EBITDA growth and debt paydown flow through to equity value is essential.
Company purchased at 8x EBITDA, exit assumed at 8x. EBITDA grows 50%. Debt paid from $60M to $30M. Entry equity $40M. What's exit equity value?
Exit Equity Value = (Exit EBITDA × Exit Multiple) - Remaining DebtStart with enterprise value at exit, then subtract remaining debt to get equity value.
What Makes a Good LBO Candidate?
Not all companies can support an LBO. You need stable cash flows to service debt. Let's test your understanding:

Key LBO Formulas
Essential LBO Calculations
| Term | Definition | Note |
|---|---|---|
| MOIC (Multiple of Invested Capital) | Exit Equity Value / Initial Equity Investment | Measures total return |
| IRR (Internal Rate of Return) | Annualized return over hold period | Time-adjusted return |
| Exit Equity Value | (Exit EBITDA × Exit Multiple) - Remaining Debt | What you get back |
| Debt/EBITDA | Total Debt / EBITDA | Leverage ratio |
