LBO interview questions and a worked paper LBO
In a leveraged buyout, a private equity firm buys a company using a lot of borrowed money. The company's own cash flow pays the debt down, and the sponsor earns its return when it sells. Returns come from three levers: EBITDA growth, multiple expansion and debt paydown.
Worked example: buy $100 of EBITDA at 10x ($1,000), funded with $600 of debt and $400 of equity. In five years EBITDA is $150, you exit at 10x ($1,500), and debt is down to $300. Exit equity is $1,500 − $300 = $1,200, so MOIC is $1,200 ÷ $400 = 3.0x and IRR is about 25%.

Debt magnifies equity returns.
Why does leverage increase equity returns?
- Debt is free, so returns rise automatically
- It lowers the company's taxes to zero
- A smaller equity check captures the same EV gains ✓
- It raises the company's EBITDA directly
Gains on the whole company accrue to a smaller equity base.
What's the main risk of using more debt?
- Returns are lower when things go well
- The company pays less in taxes when interest expense goes up

- The company has to cut employees
Leverage cuts both ways.
LBO: entry EBITDA $100 at 10x, funded with $500 debt and $500 equity. In year 5, EBITDA is $130, the exit multiple is 10x and $300 of debt remains. Exit equity is:
- $1,300
- $1,000 ✓
- $800
- $500
Exit EV = $130 × 10 = $1,300. Subtract $300 of remaining debt: $1,000 of equity.
You put in $500 of equity and get $1,000 of equity back at exit. MOIC is:
- 1.3x
- 2.0x ✓
- 2.6x
- 3.0x
$1,000 ÷ $500 = 2.0x.
Year-5 EBITDA is $130 and $300 of debt remains. At an 11x exit multiple, exit equity is:
- $1,130 ✓
- $1,100
- $1,430
- $1,000
$130 × 11 = $1,430 EV, less $300 debt = $1,130.
Paper LBO: EBITDA $50 at 8x. What's the entry enterprise value?
- $58
- $400 ✓
- $350
- $450
50 × 8 = $400.
Entry EV is $600 with 60% debt. How much equity?
- $360
- $600
- $400
- $240 ✓
40% × $600 = $240.
Entry EV $1,000, debt $600. Entry equity is:
- $600
- $400 ✓
- $1,600
- $1,000
1,000 − 600 = $400.
