LBO Mechanics in 15 Minutes
The Hook
A leveraged buyout, or LBO, is how a buyer can purchase a large company while putting in surprisingly little of their own money. The trick is debt, and understanding it explains how private equity makes (and sometimes loses) fortunes. Learn the few moving parts and you can follow any buyout conversation with confidence.
Plain English
An LBO is buying a company mostly with borrowed money. Picture buying a house with a mortgage: you put down a small slice of your own cash (the equity) and borrow the rest (the debt), and the house's value, plus the rent it earns, pays you back. An LBO does the same with a business. A buyer purchases a company using a small amount of their own equity and a large amount of debt, then uses the company's own cash flow to pay down that debt over time. Years later they sell the company. Because the debt has been paid down and the business has ideally grown, the equity portion is worth far more than what they put in. Two numbers measure how well it worked. MOIC, the Multiple On Invested Capital, asks how many times your money you got back: exit equity divided by the equity you invested. IRR, the Internal Rate of Return, measures the annual rate of return, which accounts for how long the money was tied up. Debt is the amplifier. It magnifies gains when things go well, and it magnifies losses when they do not, which is exactly why an LBO is powerful and risky at the same time.
The Math
The heart of an LBO is simple. At purchase, the price is split into debt and equity. Over the holding period, the company's cash pays down the debt. At exit, the company is sold, the remaining debt is repaid, and whatever is left is the equity to the buyer. MOIC compares that exit equity to the equity invested. We keep the example clean by ignoring interest and assuming the sale price equals the purchase price, so you can see the engine clearly.
- Equity invested = purchase price - debt raised
- Exit equity = sale price - remaining debt at exit
- MOIC (Multiple On Invested Capital) = exit equity / equity invested
A buyer purchases a company for 100,000,000 dollars. They fund it with 70,000,000 of debt and 30,000,000 of their own equity. Equity invested = 100,000,000 - 70,000,000 = 30,000,000 dollars. Over five years, the company's cash flow pays down 40,000,000 of the debt, leaving 30,000,000 still owed. Now they sell the company for the same 100,000,000 (no change in price, to keep it simple). Exit equity = sale price - remaining debt = 100,000,000 - 30,000,000 = 70,000,000 dollars. So 30,000,000 of equity turned into 70,000,000, purely by using the company's cash to pay down debt. MOIC = 70,000,000 / 30,000,000 = about 2.33 times. The buyer more than doubled their money without the company's value rising at all.
Same start: buy for 100,000,000 with 70,000,000 debt and 30,000,000 equity. This time the business grows, and it sells five years later for 130,000,000 instead of 100,000,000. The debt was paid down by the same 40,000,000, leaving 30,000,000 owed. Exit equity = sale price - remaining debt = 130,000,000 - 30,000,000 = 100,000,000 dollars. MOIC = 100,000,000 / 30,000,000 = about 3.33 times. Compare that to Example 1's 2.33 times. The extra value came from two engines working together: paying down debt and growing the business. This is the dream scenario private equity is chasing, and it shows why buyers care so much about both cost discipline and growth.
Debt cuts both ways. Same buyout: 100,000,000 price, 70,000,000 debt, 30,000,000 equity. But the business struggles. It pays down only 10,000,000 of debt, leaving 60,000,000 owed, and it sells for just 80,000,000. Exit equity = sale price - remaining debt = 80,000,000 - 60,000,000 = 20,000,000 dollars. MOIC = 20,000,000 / 30,000,000 = about 0.67 times. The buyer put in 30,000,000 and got back only 20,000,000, a loss of a third of their money, even though the company's sale price fell by only 20 percent. That is leverage working against you: a modest drop in the business value became a much larger drop in the equity, because the debt has to be repaid in full first.
The Lingo
- LBO (leveraged buyout)
- Buying a company using mostly borrowed money, then using the company's cash flow to pay down that debt over time.
- Leverage
- The use of debt to fund a purchase. It amplifies both gains and losses on the equity.
- Equity invested
- The buyer's own cash put into the deal. Purchase price minus the debt raised.
- Exit equity
- What the equity is worth when the company is sold: the sale price minus any debt still owed.
- MOIC (Multiple On Invested Capital)
- How many times you got your money back. Exit equity divided by equity invested.
- IRR (Internal Rate of Return)
- The annual rate of return on the investment, which accounts for how long your money was tied up.
- Debt paydown
- Using the company's cash flow to reduce the loan over the holding period, which grows the equity portion.

In the Room
The Trap
Forgetting that leverage amplifies losses as well as gains. The same debt that turns a flat exit into a doubling of your money will turn a modest decline into a painful loss, because the debt gets repaid in full before the equity sees a cent. A buyout that looks brilliant in the upside case can be brutal if cash flow falters or the exit price dips. The fix is to always stress test the downside: ask what happens to the equity if the sale price falls and the debt cannot be paid down as planned. If a modest dip wipes out most of your equity, the deal is riskier than it looks.

Practice Out Loud
You are evaluating a buyout funded with 70 percent debt that the deal team says could return 3 times their money. In 90 seconds, explain how the debt drives that return and why you want to stress test the downside. The AI will play the deal lead, who pushes back with: the cash flow is stable, so why are you worried about the leverage?
