Every leveraged buyout starts with the same question: where does the money actually come from, and where does it actually go? The answer lives in a single schedule that appears in every private equity model, every investment banking pitch book, and every LBO interview question you're likely to face: the Sources and Uses table. It looks simple — two columns of numbers that have to add up to the same total — but understanding what belongs in each column, and why, is one of the clearest signals an interviewer uses to separate candidates who understand deal structuring from candidates who have only memorized formulas.

What Is a Sources and Uses Table?

A Sources and Uses table (sometimes written as "Sources & Uses" or abbreviated "S&U") is a two-sided schedule that lays out exactly how a transaction is financed. The Uses side lists everything the deal has to pay for: the purchase price of the target company, the repayment of any existing debt that isn't being assumed, transaction fees, and occasionally other cash items like minimum cash requirements. The Sources side lists where that capital comes from: new debt tranches raised for the deal, equity contributed by the private equity sponsor, and sometimes rolled-over equity from existing management or the seller.

The defining feature of the schedule — and the part that trips up candidates who haven't internalized it — is that Total Sources must always equal Total Uses. This isn't a coincidence or a rounding exercise. It's a mechanical identity: every dollar spent on the transaction has to be raised from somewhere, and every dollar raised has to be spent on something. If you're asked to build a Sources and Uses table for a leveraged buyout, the entire exercise is really about correctly identifying which line items belong on which side and then solving for whichever figure is left as the balancing item.

Why Sources and Uses Tables Matter in Leveraged Buyouts

The Sources and Uses table isn't a side calculation in an LBO model — it's the foundation everything else is built on. Before you can build a debt schedule, before you can project free cash flow available for debt paydown, and before you can compute a Multiple of Money or an IRR, you first need to know exactly how much debt is being raised and exactly how much equity the sponsor is putting in. Those two numbers come directly out of the Sources and Uses table.

This is precisely why the topic shows up so often in interviews for private equity, leveraged finance, and M&A advisory roles. If you can't correctly build a Sources and Uses schedule, you can't credibly claim to understand how a leveraged buyout is financed. It's also a natural companion question to explaining what an LBO is and why leverage increases equity returns in the first place — the Sources and Uses table is where that leverage decision gets made concrete, in dollars, for a specific deal.

The Uses Side: Where the Money Goes

The Uses side answers a single question: what does this transaction require capital for? In a straightforward corporate leveraged buyout, the Uses side typically includes the following line items.

Purchase of the Target (Enterprise Value)

The largest line item is almost always the purchase price, usually expressed as the target's Enterprise Value. This is the price the buyer is paying to acquire the operating business, before layering in any additional cash requirements created by the transaction itself.

Refinancing of Existing Debt

Most LBO targets already carry some debt on their balance sheet before the deal happens. Unless the buyer is explicitly assuming that debt as part of the transaction (relatively rare, since sponsors typically want a clean capital structure they control), the existing debt has to be repaid at closing. That repayment is a genuine use of cash — the deal has to fund it just as surely as it funds the purchase price itself.

Transaction Fees

Financing fees paid to the banks arranging the debt, advisory fees paid to investment banks and consultants, and legal fees all have to be paid in cash at closing. New candidates frequently underestimate this line item or forget it entirely, which is one of the most common mistakes interviewers watch for.

Other Cash Uses

Depending on the deal, the Uses side can also include a minimum cash balance left on the target's balance sheet post-close, or a cash sweep to fund a dividend recapitalization down the line. For a standard entry-level Sources and Uses question, though, purchase price, debt refinancing, and fees are the three pillars you need to get right first.

The Sources Side: Where the Money Comes From

Once you know how much capital the deal requires, the Sources side answers where that capital is actually raised. In a typical leveraged buyout, the Sources side is a mix of debt and equity, layered by seniority and cost.

Senior Secured Debt

This is usually the largest, cheapest, and most senior tranche of debt in the capital structure. Lenders providing senior secured debt get paid first in a downside scenario and typically size their commitment as a multiple of the target's EBITDA, which is why understanding how leverage flows through a company's cost of capital is closely related to understanding how much senior debt a lender is willing to provide.

Subordinated or Mezzanine Debt

Below the senior tranche sits subordinated debt — sometimes called mezzanine debt — which carries a higher interest rate to compensate lenders for being repaid after the senior lenders in a default scenario. Sponsors use subordinated debt to push leverage higher without diluting their own equity stake further, but it makes the overall capital structure more expensive and less flexible.

Management Rollover Equity

It's common for existing management or founders to "roll over" a portion of their existing ownership stake into the new deal rather than cashing out entirely. This aligns their incentives with the new owner and reduces the amount of fresh equity the sponsor has to contribute.

Sponsor Equity — The Plug

This is the line item candidates most often get wrong. Sponsor equity is not chosen independently the way the debt tranches are. It is the balancing figure — the plug — that makes Total Sources equal Total Uses once every other line on both sides has been filled in. If you try to size sponsor equity as an independent input rather than solving for it last, you'll get a Sources and Uses table that doesn't balance, and in an interview setting that's an immediate red flag.

Why the Two Sides Must Always Balance

The balancing requirement is what makes the Sources and Uses table useful rather than just a list of numbers. Because Sources must equal Uses by construction, the schedule forces you to be explicit and complete about every cash requirement and every source of financing. Miss a fee, forget to refinance existing debt, or overstate how much debt a lender will actually provide, and the imbalance shows up immediately as an error in your sponsor equity plug — either too small (meaning you've understated the deal's true capital requirement) or implausibly large (meaning you've either overstated Uses or underestimated available debt financing).

This is exactly the mechanic tested in the Sources and Uses Table practice case: a $500 million purchase enterprise value, $50 million of existing net debt to refinance, and $15 million of transaction fees bring Total Uses to $565.0m. Once you add up $250 million of senior debt, $75 million of subordinated debt, and $20 million of management rollover equity, you have $345.0m of known Sources — which means the sponsor has to write a $220.0m equity check to make the two sides balance.

How Leverage and the Equity Check Interact

The size of the sponsor equity plug is not just an accounting output — it's one of the most important strategic decisions in the entire deal. A smaller equity check relative to Total Uses means the deal is more highly levered, which amplifies both the upside and the downside of the investment. A larger equity check means less leverage, lower risk, but also a lower expected return if the deal performs well, since there's more equity capital sharing in the same dollar of value creation.

This is why private equity firms spend so much time on target screening before they ever get to the Sources and Uses table. A business needs stable, predictable cash flow to support a highly levered capital structure in the first place — which is exactly the framework covered in what makes a good LBO target and its real-world screening variant on a car-sharing business. The Sources and Uses table is where that screening judgment turns into an actual capital structure with actual dollar amounts.

Common Variations in Real Deals

While the entry-level version of this exercise usually involves a clean purchase of a standalone target, real Sources and Uses tables get more complicated in a few recurring ways.

Seller notes and earn-outs. Sometimes part of the purchase price is deferred through a seller note or an earn-out tied to future performance, which reduces the amount of upfront cash the buyer needs and therefore reduces both debt and equity requirements at close.

Delayed-draw and revolver facilities. Not all debt capacity has to be drawn at closing — a revolving credit facility might be available but undrawn, sized to cover working capital swings rather than the purchase price itself.

Add-on acquisitions. When a portfolio company makes a follow-on acquisition (a "bolt-on" or "add-on"), a fresh Sources and Uses table gets built for that smaller transaction, often funded with a mix of the platform's existing cash flow, incremental debt, and sometimes additional equity from the sponsor.

Dividend recapitalizations. Later in a hold period, a sponsor might raise new debt specifically to pay itself a dividend — in which case the Uses side is simply "cash to equity holders" rather than a purchase price, but the same balancing logic still applies.

How Sources and Uses Connects to Returns

The sponsor equity figure from the Sources and Uses table becomes the denominator in every return calculation that follows. Once you know the equity check at entry and can project the equity value at exit, you can compute a Multiple of Money and an approximate IRR — the two metrics private equity firms use to decide whether a deal clears their return hurdle. This is the same logic explored in IRR-based pricing in private equity, where the maximum price a sponsor can pay for a target is worked backward from a target IRR rather than forward from a valuation multiple. If you understand how the Sources and Uses table produces the equity check, you're already halfway to understanding how sponsors calculate the maximum price they can pay for an LBO target while still hitting their return targets.

It's also worth noting that the debt raised in the Sources and Uses table isn't free — it carries a cost that flows into the target's weighted average cost of capital once the deal closes, which is the same underlying concept tested when interviewers ask you to recompute WACC after a change in leverage.

Common Mistakes When Building a Sources and Uses Table

A handful of errors show up again and again, whether in a live interview or in a first-pass model built by a new analyst.

  • Treating the purchase Enterprise Value as the only line on the Uses side, and forgetting that refinancing existing debt and paying transaction fees are just as real a use of cash.
  • Trying to size the sponsor equity check as an independent assumption instead of solving for it as the plug that forces Sources to equal Uses.
  • Confusing Enterprise Value and Equity Value when sizing the Uses side of the schedule — the Uses side is generally built off Enterprise Value plus any incremental cash requirements, not the seller's straight equity proceeds.
  • Overstating how much debt a lender will realistically provide relative to the target's EBITDA, which produces an equity check that looks smaller — and a leverage ratio that looks safer — than the deal can actually support.
  • Forgetting that Sources and Uses balancing isn't a check you perform after the fact; it's the entire structural logic of why the sponsor equity line exists in the first place.

Practicing With a Real Case

Reading about the mechanics of a Sources and Uses table only gets you so far — the real test is whether you can build one from a clean set of assumptions under interview conditions, without a spreadsheet to lean on. The Sources and Uses Table case walks through exactly this scenario with a full worked solution, and pairs naturally with practicing the basic LBO return mechanic and reviewing how the broader M&A process unfolds around any transaction, leveraged or otherwise.

If you're preparing for private equity or leveraged finance interviews, treat the Sources and Uses table as a warm-up exercise you should be able to do cold, in under two minutes, before moving on to the harder questions about debt paydown, value creation levers, and exit assumptions that build on top of it.
