LBO Affordability Analysis: “Floor Valuation”
At the end of the day, the projected fund returns drive investment decisions, regardless of how compelling the fundamentals of the company (and industry) are or how well the target company aligns with the fund’s portfolio strategy.
The LBO model can be used to quantify the maximum purchase price that could be paid at entry, while still realizing the minimum 20% to 25% IRR (“hurdle rate”).
Therefore, an LBO model provides a so-called “floor valuation” of a potential LBO transaction, since it is used to determine what a financial sponsor could afford to pay for the target under consideration.
Given the risk profile associated with using significant debt financing and the relatively short investment horizons (~3 to 8 years), the hurdle rate to invest (i.e. the cost of equity) is going to be higher than if an identical business had no exposure to those same LBO-related risks.
Said differently, the implied present value (or target enterprise value) will decline due to the higher hurdle rates of financial sponsors than valuations conducted under the traditional discounted cash flow (DCF) or relative valuation approaches — all else being equal.

We’ll now move to a modeling exercise, which you can access by filling out the form below.
Step 1. LBO Entry Assumptions
Suppose we’re provided with the following entry assumptions for a proposed leveraged buyout (LBO).
- LTM Entry EBITDA = $25mm
- Entry Leverage Multiple = 6.0x
From those two assumptions, we can calculate that the initial amount of debt raised to finance the deal was $150mm.
- Initial Debt Raised = $25mm LTM EBITDA × 6.0x Leverage Multiple = $150mm
Next, there are three more important transaction assumptions:
- LBO Holding Period = 5 Years
- Transaction Fees (% TEV) = 2.5%
- Financing Fees (% TEV) = 2.0%
Step 2. LBO Exit Assumptions
With those entry assumptions filled out, we can start working on the exit assumptions before reaching the ability-to-pay analysis.
For our range of potential exit multiples, the first input will be 9.0x – and using a step function of 0.5x – we’ll extend this to 11.0x.
As for remaining exit assumptions, we’ll assume the following:
- LTM Exit EBITDA = $25mm
- Net Debt at Exit = $125mm
To calculate the enterprise value on the date of exit, we’ll multiply the applicable exit multiple by the LTM exit EBITDA assumption.
For example, if we assume the investment will be exited at a multiple of 9.0x, the following formula is used:
- Enterprise Value @ Exit: 9.0x × $25mm = $225mm
Since we’re making our way down to the common equity value on the date of exit (i.e. at the end of Year 5), we must deduct the net debt and transaction expense (e.g. M&A advisory fees).
Note that the reason we deduct transaction expenses in this step, but not financing expenses, is that advisory fees are required again when selling the company, while financing fees are not.
Continuing off our 9.0x exit multiple example, the formula below calculates the residual common equity value, which we’ll recalculate for each exit multiple assumption.
- Common Equity Value @ Exit = $225mm – $125mm – $6mm = $94mm
Step 3. Ability to Pay Analysis Calculation Example (ATP)
In the next portion of our tutorial, we can now estimate the implied purchase price to achieve our targeted deal IRR.
Here, we’ll have two target IRRs:
- 20.0% Minimum IRR
- 25.0% Minimum IRR
One significant component of the IRR is the required sponsor equity contribution needed to complete the transaction.
We’ll first calculate the approximate sponsor equity contribution using the formula below:
- Sponsor Equity Contribution = Common Equity Value @ Exit / (1 + Minimum Deal IRR) ^ LBO Holding Period
Upon extrapolating this calculation for the entire range of exit multiples, we can link to our assumptions from earlier.
- (+) Initial Debt Raised: $150mm
- (–) Transaction Expenses: TEV × Transaction Fees %
- (–) Financing Fees: TEV × Financing Fees %
If you are wondering why transaction fees are accounted for twice, this is because M&A advisory services are required two times:
- Purchasing the Target (Buy-Side M&A)
- Exiting the Investment (Sell-Side M&A)
Once completed, we have the enterprise value as of the date of purchase. From the enterprise value at exit, we can divide that figure by the LTM entry multiple to get the implied purchase multiple that enables us to achieve the desired return.
- Implied Maximum Purchase Multiple = Enterprise Value @ Exit ÷ LTM Entry EBITDA
According to our model, assuming an exit multiple of 10.0x and required minimum IRR of 20.0x, the maximum purchase multiple we should be willing to pay should be around ~7.5x.
The same steps from our 20.0% hurdle rate section could subsequently be replicated for the 25.0% minimum deal IRR, as well as for higher required IRRs if needed.
Step 4. Interpretation of Ability to Pay Analysis Model (ATP)
It is important to understand, however, that an ability-to-pay analysis (ATP) is only an approximation of the maximum purchase price (and multiple) and there remains room for error.
For example, for the sake of simplicity and also to avoid creating a circularity, the TEV on the date of exit was used, rather than the entry TEV when calculating the transaction fees.
While these minor discrepancies are unlikely to have a tangible impact on the pricing recommendation, these imperfections can cause slight mismatches in the return figures and are something to be aware of.
Hence, most complex LBO models with ATP tabs use the “ROUND” Excel function, as the implied multiples are meant to serve as a rough point of reference (i.e. an estimated ceiling), but NOT a precise purchase multiple.
To recap, an LBO model is often called a “floor valuation” as it can be used to determine the maximum purchase price the buyer can pay while still reaching the fund specific returns thresholds.
The purchase multiple is among the most important factors that determine the success (or failure) of an LBO — which an ability-to-pay analysis is intended to guide.

If a sponsor only purchases 80% of the company with Management rolling over the remaining 20%, would line 21 in your excel file include the initial equity contributions from both the sponsor and management? Or should line 21 only reflect the sponsor’s equity contribution?
Do we also have to take Cash to B/S or min. cash requirements into account as an (-) expense after the financing fees line?
Hi, many thanks for this. Two quick questions please: How do you get to $38 for that Sponsor Equity Contribution? I tried the formula you wrote above but it does not give me this value. Can you please clarify? Why are we removing Initial Debt Raised to get to EV… Read more »
