Leveraged Buyout (LBO) vs Discounted Cash Flow (DCF): Key Differences
Two ways to put a price on a company. One asks what the business is worth, the other what a buyer using borrowed money can afford.
- Private equity & funds
LBO vs DCF comes down to whose return sets the price. A discounted cash flow (DCF) model values a company on its future cash, converted into today’s money. A leveraged buyout (LBO) model finds the most a buyer can pay with mostly borrowed money and still hit its target return. Use a DCF for what a business is worth. Use an LBO for what a buyout fund can afford.
If you hold shares in a private company, both numbers can matter to you. A DCF often sits behind the valuation of your shares, for example in a 409A report. An LBO model sits behind the offer a buyout fund makes if it wants to buy the whole company. The second number is often lower, because the buyer needs a higher return.

Leveraged Buyout vs Discounted Cash Flow: What Is the Difference?
A DCF vs LBO model comparison starts with the question each one answers. The table compares them on definition, inputs, who uses each, legal and tax treatment, risk, liquidity and a typical example.
A DCF prices the business at the cost of capital. An LBO prices it at a buyout fund’s target return, which is usually higher
As of October 2026 · 26 U.S.C. §163(j); 26 CFR §1.409A-1(b)(5)(iv)(B); Dell press release (02.05.2013, SEC EDGAR). US rules.
LBO vs DCF Model: How Each One Is Built
The DCF Model
- Forecast cashEstimate the company’s free cash flow for five to ten years. That is the cash left after running the business and paying for new equipment.
- Pick a discount rateChoose the yearly return investors need for this level of risk. A riskier business gets a higher rate.
- Add the years after the forecastEstimate a terminal value for everything beyond the last forecast year, usually with a steady growth rate.
- Discount and addConvert each year’s cash, and the terminal value, into today’s money and add them up. The result is the enterprise value, the value of the whole business before debt.
The LBO Model
- Set the debtDecide how much the company can borrow, often as a multiple of EBITDA, earnings before interest, taxes, depreciation and amortization.
- Repay from cash flowEach year, cash flow pays the interest, and what is left pays down the debt.
- Assume an exitPick a sale year and a price, usually a multiple of EBITDA in that year. Subtract the debt still owed to get the equity at exit.
- Solve for the priceWork back to the equity that turns into that exit value at the target internal rate of return. Add the debt. That is the most the buyer can pay.
The two models share one input: the company’s cash flow. They use it differently. The DCF discounts it at the cost of capital. The LBO uses it to repay debt, and lets the buyer’s target return set the price.
One Company, Two Valuations: A Worked Example
Take an illustrative company with EBITDA of $50M today, growing to $60M in five years. Its free cash flow rises from $30M to $38M a year.
DCF at a 10% Discount Rate
Illustrative company made up for this example. Rounded to $0.1M, so rows may not add exactly
The terminal value makes up 70% of the result. That is why a DCF is so sensitive. Move the discount rate one point and the value moves by more than a tenth:
- Discount rate 9%$428.3M → $490.8M, +15%
- Discount rate 11%$428.3M → $379.7M, −11%
LBO at a 20% Target Return
Illustrative. The buyer pays and sells at the same multiple of EBITDA. Tax effects of interest are left out
The buyer turns $101.2M of equity into $251.7M, a 2.49x multiple. Debt does much of the work: the company repays $80.3M of it with its own cash. At a 25% target, the most the buyer could pay falls to $320.4M. Paying and selling at the same multiple keeps multiple expansion out of the result.
- DCF value$428.3M at a 10% discount rate
- LBO maximum price$351.2M at a 20% target, $77.1M or 18% lower
Tax law can change the LBO math. US law caps the deduction for business interest at 30% of adjusted taxable income, a tax measure of operating profit (26 U.S.C. §163(j)). If that income were close to the $50M of EBITDA, the cap would be about $15M. First-year interest here is $20M, so part of it would carry forward to later years.
LBO vs DCF Pros and Cons: A Verdict on Each
LBO Model
- For
- Shows what a real buyer with real financing can pay. Makes the role of debt visible. Shows the range buyout funds can bid in a sale.
- Against
- Depends on lenders and on an exit years away. Says what one type of buyer can pay. A buyer that needs less return, or can use the business better, may pay more.
Verdict: the LBO model is the tool for pricing a buyout, and for a seller who wants to know what financial buyers can offer. It sets a price for one buyer type. It does not measure what the business is worth to everyone.
DCF Model
- For
- Values the business on its own cash flows, whoever owns it. Works for any company with a cash flow that can be forecast. Named in US 409A valuation rules.
- Against
- Very sensitive to the discount rate and the terminal value. Hard to use for young companies with no profits yet. A forecast is only as good as its assumptions.
Verdict: the DCF is the tool for estimating what a company is worth, and the starting point for a fair value. For an early-stage company with no stable cash flow, use it next to other methods, such as recent funding rounds and comparable companies.
A DCF tells you what a business is worth at the cost of capital. An LBO tells you the most a buyout fund can pay and still hit its return. When a fund bids, the second number usually sets the offer.
DCF vs LBO: What Each Means for a Private Company Shareholder
If you hold shares in a private company, a DCF may already shape the value of your shares. Valuations under US 409A rules, which set the price of employee stock options, consider “the present value of anticipated future cash-flows” among other factors (26 CFR §1.409A-1). See what a 409A valuation is and private company valuation for how those numbers are built.
An LBO matters when a buyout fund wants to buy the whole company. Its model sets the offer, and the offer sets the price you receive for your shares. A company can also borrow to pay out existing owners without a sale, which is a recapitalization. A minority stake that cannot easily be sold may be valued lower again. That gap is covered in DLOM.
Common Mistakes
- Treating an LBO price as the company’s valueIt is what one kind of buyer can pay at its target return. Other buyers may value the company higher.
- Trusting a DCF to the dollarOne point on the discount rate moved the example by 11% to 15%. Ask for the range.
- Ignoring the terminal valueIn the example it is 70% of the DCF result. Check the growth rate behind it.
- Counting on multiple expansionAn LBO that only works if the exit multiple is higher than the entry multiple is a bet on the market.
- Forgetting the interest capIn the US, interest above the 30% limit is not deductible that year. The tax saving from debt can be smaller than planned.

What People Ask About LBO and DCF Models
It depends on the inputs, but the DCF is usually higher. A DCF discounts at the cost of capital. An LBO model prices at a buyout fund’s target return, which is usually higher. In the example on this page, the DCF gives $428.3M and the LBO $351.2M.
Yes, of a narrow kind. It values a company from the viewpoint of one buyer type: a fund that borrows heavily and needs a set return. That makes it a price test. A DCF is the broader estimate of value.
Debt lets the fund buy a larger company with less of its own money. If the business does well, the gain on the fund’s equity is larger. If it does badly, the loss is larger too, because the lenders are paid first.
You can, but with care. A startup with no profits has no stable cash flow to forecast, so the result rests on assumptions. Valuers usually combine it with other methods, such as recent funding rounds and comparable companies.
