LBO Model Basics: How Leveraged Buyouts Create Returns

Key takeaway

How a leveraged buyout works — sources and uses, the three levers of LBO returns (deleveraging, EBITDA growth and multiple change), and how to model one.

A leveraged buyout (LBO) is the acquisition of a company using a large amount of borrowed money, where the acquired company's own cash flows repay the debt. Private equity firms use LBOs to amplify returns: by funding most of the purchase with debt and a smaller slice of equity, a modest rise in the company's value translates into a large gain on the equity. Here is how an LBO works, how the returns are created, and how to model one.

Definition

An LBO uses debt to fund most of an acquisition; the target's cash flows service and repay that debt, so returns accrue to the small equity cheque through debt paydown, earnings growth and any change in the exit multiple.

Sources and uses

Every LBO starts with a sources-and-uses table: where the money comes from (debt and sponsor equity) and where it goes (buying the business and paying fees). The more debt in the structure, the smaller the equity cheque — and the higher the potential return, at the cost of higher risk.

Item	Amount ($m)	% of total
Senior + subordinated debt	300	60%
Sponsor equity	200	40%
Total sources	500	100%
Purchase enterprise value	480	96%
Transaction fees	20	4%
Total uses	500	100%

The three levers of LBO returns

An LBO equity return comes from three sources. First, deleveraging: the company's free cash flow pays down debt, so more of the enterprise value belongs to equity each year. Second, EBITDA growth: growing earnings raises enterprise value. Third, multiple change: selling at a higher EV/EBITDA multiple than you bought adds value, while a lower one destroys it. The chart below decomposes a five-year hold.

Entry equity of $200m grows to $440m — roughly 2.2x, an IRR near 17%.

Why leverage amplifies returns

In the example, enterprise value rose from $480m to roughly $570m — under 20%. But because equity was only $200m and debt was repaid along the way, equity more than doubled to $440m. That is the power of leverage: it magnifies the equity return on any gain in enterprise value. It also magnifies losses, which is why LBO targets need stable, predictable cash flows to service the debt safely — exactly what the debt service coverage ratio tests.

What makes a good LBO candidate

The ideal target has steady, predictable free cash flow (to service debt), low existing leverage (room to add debt), modest ongoing CAPEX (more cash for debt paydown), and a credible path to growth or margin improvement. Cyclical or capital-hungry businesses make risky LBOs, because a downturn can breach debt covenants when cash flow falls.

Model an LBO

A simplified worked LBO

Buy a business for $100m at 5x EBITDA of $20m, funded with $60m of debt and $40m of equity. Over five years, EBITDA grows to $28m and free cash flow repays $30m of debt. Exit at the same 5x multiple gives an enterprise value of $140m; subtract remaining debt of $30m for $110m of equity. The sponsor's $40m has become $110m — roughly a 22% IRR over five years, driven by debt paydown and EBITDA growth even without any multiple expansion.

Decomposing return into deleveraging, growth and multiple change is the heart of LBO analysis, because only the first two are within the buyer's control.

Leverage cuts both ways

Debt amplifies equity returns when the business performs, but the fixed repayment schedule can force distress if cash flow disappoints. This is why LBO targets are typically stable, cash-generative businesses rather than volatile or cyclical ones.

What sponsors ultimately underwrite

Strip an LBO back to its essentials and the sponsor is buying a stream of cash flows capable of servicing debt, then betting that disciplined operation and sensible leverage convert that stream into an outsized equity return. The model exists to test that bet under conservative assumptions before any capital is committed.

Frequently asked questions

How does a leveraged buyout create returns?

Through debt paydown from cash flow, EBITDA growth, and multiple expansion at exit. High leverage amplifies equity returns because debt is repaid before equity captures the remaining value.

How much leverage is used in an LBO?

Typically 50–70% of the purchase price is debt, often 4–6x EBITDA, depending on cash-flow stability and credit conditions. More stable cash flows support more debt.

What IRR do LBO sponsors target?

Private equity funds commonly target 20–25%+ IRR over a 3–5 year hold, using leverage, operational improvement and a disciplined entry multiple to get there.
