The short answer: The price agreed by a buyer and seller is only one part of a viable acquisition. A deal also needs enough money at closing, enough cash left to operate after closing, and repayment terms the acquired business can support. There is no universal 40% equity and 60% debt average. In this guide, that split is one illustrative structure, not a market statistic or a financing recommendation.
A founder has spent 25 years building a company. A credible buyer offers a fair price. The broker secures a letter of intent. Then the buyer discovers that the bank will lend less than assumed, the seller expected all cash at closing, and the target needs inventory funding on day one. The price was agreed, but the transaction is not financeable in its present form.
For acquisitions roughly between $1 million and $50 million, financing often determines which buyers can participate, how much cash the seller receives at closing, how risk is shared, and whether the company survives its first year under new ownership. This article is for owners, buyers and M&A originators who want to build a deal that can actually close and operate. Specific products, lender policies, taxes and legal requirements depend on where the deal is made.
First, the 40/60 question: what is the average debt-to-equity split?
We did not find a reliable, comparable average for all $1 million to $50 million private acquisitions. A headline saying “the average deal is 40% equity and 60% debt” would imply more certainty than the evidence supports. Buyer type, target cash flow, seller participation, collateral, purchase structure, financing market and deal size change the mix. Even the denominator changes when one source reports a percentage of purchase price and another a percentage of total funds required.
There is also a vocabulary problem: debt is financing. The meaningful question is how much of the total funding comes from buyer or investor equity, senior and junior debt, seller credit, and seller rollover. An earnout is contingent purchase consideration, not cash available at closing. A seller note is debt, not equity, even if a lender agrees to subordinate its payments. A rollover is equity, not a loan.
A useful, but limited, reference point comes from a review of 100 selected winning LOIs: 89% included at least one of seller financing, an earnout or rollover equity; seller financing appeared in 53% [1]. These are selected LOIs, not a representative market average or evidence that 89% of completed transactions used these features. The figures show why creative structures deserve attention, but they do not prove a 40/60 rule. See the source notes.
What appeared in 100 selected winning LOIs?
Source [1], September 2026. Selected winning LOIs on one deal platform, not all closed deals. Categories overlap, so the bars must not be added together. These are frequencies of use, not percentages of deal value.The two equations every broker should put beside the valuation
Economic sources = funded buyer/investor equity and debt + deferred seller note + seller rollover, if applicable.
Closing cash test: funded cash sources = cash paid to seller and other recipients at closing + costs and reserves.
Each side of each equation must balance. Deferred seller consideration, such as a seller note or rollover, reduces the cash that must be paid to the seller at closing, but it does not erase the obligation or economic purchase price. Show seller notes and rollover as distinct components of the transaction, and specify exactly what amount is paid now versus later. Do not count a seller note as cash in the closing bank account.
Next write a separate post-close equation: cash available for debt service = operating cash generated after taxes, required capital spending and working-capital needs, using definitions agreed with the lender. Compare that capacity with scheduled principal and interest, seller-note payments and a downside case. EBITDA is a useful starting point, but is not the same as cash available to service debt.
A $10 million headline price might require $11 million of total funding because the buyer also needs deal costs and operating liquidity. The correct debt percentage for that funding plan is measured against $11 million, not casually against the $10 million price. Enterprise value, equity value, cash-free/debt-free adjustments and a working-capital peg must be reconciled in the transaction documents before the final sources and uses are trusted.
What each layer of the capital stack does
| Layer | What it contributes | Cost or constraint to test |
|---|---|---|
| Buyer or investor equity | Loss-absorbing capital and commitment at closing | Dilution, control and the buyer's remaining liquidity |
| Senior acquisition debt | Often a substantial portion of cash funding | Required payments, collateral, covenants and lender priority |
| Junior or mezzanine capital | Can fill a gap when senior capacity is limited | Higher economic cost and intercreditor terms; payments vary |
| Seller note | Defers part of the seller's cash receipt | Subordination, maturity, interest, enforcement and seller risk |
| Seller rollover equity | Seller reinvests a portion of value in the post-close company | Governance, future liquidity and how exit proceeds are shared |
| Earnout | Makes some purchase consideration contingent on results | Measurement disputes, incentives and uncertainty of payment |
The stack is not a contest to maximize leverage. Senior debt may cost less than junior capital, but a short amortization can absorb cash precisely when the buyer needs to retain customers and employees. Seller financing may preserve closing cash but create a large payment later. Equity reduces mandatory debt service but can dilute control. The best mix is the one that meets closing needs and leaves the company able to execute its operating plan.
Case 1: a $2 million services acquisition
Illustrative example, amounts in USD equivalent for arithmetic only. A manager wants to acquire a recurring-revenue business for $2.0 million. Legal, accounting and closing costs are $0.1 million; the buyer also plans a $0.2 million operating reserve. Total uses are therefore $2.3 million.
Buyer/investor equity
Senior debt
Seller note
In economic terms, the seller receives $1.6 million cash at closing and a $0.4 million note for the rest of the $2.0 million price. Buyer equity and funded bank debt provide $1.9 million cash: $1.6 million goes to the seller, and $0.3 million covers costs and reserve. The note is not an extra $0.4 million in the closing bank account.
Without the note, this same buyer would need another $0.4 million of equity or lender debt, a lower price, or a different transaction. With it, closing may be possible, but the seller takes credit risk and needs clear payment, security and subordination terms. The broker should ask whether the seller actually accepts deferred proceeds before presenting a fully funded offer.
Case 2: a $10 million acquisition and the illustrative 40/60 stack
Assume a $10.0 million purchase price, $0.4 million transaction expenses and $0.6 million of post-close working capital. Total economic uses are $11.0 million. The parties agree on $1.4 million seller financing, so the seller receives $8.6 million in cash at closing. The remaining $1.0 million cash is reserved for costs and working capital.
Illustrative $11.0m capital stack
Equity $4.4m + senior debt $5.2m + seller note $1.4m = $11.0m. Equity is 40% and total debt is 60% in this one example. Cash funded at closing is $9.6m; the $1.4m note is deferred purchase consideration. Values rounded in chart labels.
The split looks neat. The repayment capacity matters more. Suppose annual cash available for debt service is $1.6 million. For illustration only, a $5.2 million senior loan at an assumed 8% rate amortized over seven years requires about $1.0 million a year. If the $1.4 million seller note also bears an assumed 8% but is interest-only at first, it adds $0.112 million annually. Scheduled service is approximately $1.11 million and illustrative cash coverage is around 1.44 times. A 25% reduction in cash available drops coverage to roughly 1.08 times, before any unforeseen expense. These assumptions are not market quotes, credit thresholds or a lender offer.
Now imagine the seller insists on all cash at closing and the buyer replaces the $1.4 million note with additional senior debt on those same hypothetical loan terms. Annual senior payments on $6.6 million would be about $1.27 million, so the $1.6 million cash flow covers them by only about 1.26 times; the 25% downside leaves coverage below 1.0. A patient seller note creates near-term flexibility, but its principal eventually comes due. The parties must model the maturity, not merely celebrate lower first-year payments.
What the broker learns: The seller can receive an acceptable price, the buyer can preserve operating liquidity, and the lender can size debt to cash flow, provided the seller accepts the timing and risk. If any of those conditions fail, the 40/60 diagram is just a drawing.
Case 3: a $40 million industrial transaction
Consider a $40 million enterprise transaction with $1.2 million of expenses and $2.8 million of transition and working-capital reserves: $44 million of total economic uses. A possible structure is $14 million buyer/investor equity, $20 million senior debt, $2 million junior capital, a $3 million seller note and a $5 million seller equity rollover. These sum to $44 million. Of the $40 million consideration, the seller receives $32 million cash, keeps $5 million invested, and holds a $3 million note. Cash funding of $36 million pays the $32 million seller cash and the $4 million of costs and reserves.
That stack has $19 million of equity, including rollover, and $25 million of debt, including the seller note, measured against total uses. It may broaden the buyer pool and align the seller with the transition. It also raises hard questions: Who controls the company? When can the seller exit? What happens if performance misses plan? Which lender has priority? What if a note maturity arrives before free cash flow improves? A rollover and note cannot be described as “free money.”
The point of three cases is not that deals of a given size should use those exact percentages. It is that the definition of cash paid at close, funded cash sources, deferred consideration and post-close debt service becomes more important as the deal grows.
Why financing should enter the broker's process before the LOI
A broker can create value long before a lender issues a term sheet. The first task is to qualify the funding story without representing that financing is committed. In one survey of lower-middle-market brokers, 35% raised financing challenges in open-ended responses [5]; this is a small platform survey, not a market-wide failure rate. It reinforces a practical point: the financing gap can surface after a signed LOI, when time and credibility have already been spent.
- Clarify the seller's requirements. What minimum cash at close is needed? Is a seller note, partial rollover or earnout acceptable, and on what terms?
- Verify buyer equity. Distinguish funds available now from promised investor commitments and future capital raising.
- Reconcile the real uses. Include fees, debt payoff, working-capital adjustments, integration costs and cash reserves, not just the offer price.
- Normalize earnings carefully. Test owner add-backs, one-time costs, customer concentration, maintenance capex and the cost of replacing the seller's role.
- Run a downside case. What if sales or margin fall after the transition? Can the borrower pay debt and preserve essential operating cash?
- Map security and existing debt. Identify liens, guarantees, lease obligations, change-of-control provisions and assets already pledged.
- Sequence lender conversations. Establish which product and credit policy fit the acquisition, with confidentiality and consent managed properly. An indicative conversation is not an approval.
- Write financeable LOI terms. Financing contingency, diligence period, seller-note subordination, rollover rights and working-capital peg should be specific enough to reduce surprises. Obtain local legal and tax advice.
A broker who frames those questions helps buyers avoid overstating their capacity, helps sellers evaluate real proceeds rather than only headline price, and gives financing partners a cleaner request. The broker remains central to the transaction. Bringing in a capital partner should make that role stronger, with introductions and scope agreed transparently.
How deal location changes financing options
The mathematics of sources, uses and repayment is broadly useful, but actual financing options depend on the business, buyer and jurisdiction. Some lenders focus on cash flow, others require strong asset security, and certain markets offer government-supported or development-finance products with their own eligibility rules. A product available for one acquisition may not fit another. The right lender must be selected for the actual transaction, not assumed from a generic loan list.
For a cross-border buyer, add currency risk, tax structure, local collateral enforceability, regulatory approvals, operating-company location and the actual source of repayment to the checklist. ALOS can help organize the request and identify lenders whose mandates may fit, while each lender decides its own terms and credit approval. Our more detailed acquisition financing guide covers additional transaction mechanics.
Five deal-structure mistakes worth catching early
Ignoring fees, debt payoff and first-year operating cash understates total uses.
A note, rollover or earnout does not pay all closing obligations today.
Taxes, capex, working capital and existing debt still consume cash.
- Taking the cheapest debt without testing its schedule. A lower coupon can be offset by tight amortization, covenants or an early maturity.
- Leaving seller economics vague. A late disagreement over note priority, rollover control or earnout definitions can derail an otherwise attractive deal.
Financing will not rescue a fundamentally overpriced or weak business. It can make a sound acquisition possible when the buyer's cash, the lender's capacity and the seller's willingness to share timing and risk are organized into a coherent plan.
The question to ask before pursuing the next acquisition
Do not ask only, “What multiple can the buyer pay?” Ask, “How much cash must change hands at closing, who can provide it, what claims remain afterward, and can the operating company safely carry the obligations under a slower first year?” A $1 million transaction and a $50 million transaction demand different diligence and capital sources, but both live or die by those questions.

Frequently asked questions
What percentage of an M&A deal is typically financed with debt?
There is no reliable universal percentage for private $1 million to $50 million acquisitions across markets. Deal size, buyer, cash flow, seller terms and lender policy matter. The 40% equity and 60% debt example above is illustrative, measured against total economic uses.
Can seller financing replace buyer equity?
Sometimes it can reduce cash required at closing, but it is generally a debt obligation or deferred consideration, not buyer equity. A lender's treatment of it depends on its terms and policy. The seller bears risk and must agree.
Does an earnout fund closing?
No. It is a contingent future payment if agreed conditions are met. It can reduce immediate cash paid to the seller but cannot itself pay legal fees or fund inventory at closing.
Should a broker contact lenders before the LOI?
An early, consented discussion can test structure and information needs without presenting an indicative conversation as a commitment. Protect confidential data and follow the parties' legal and regulatory obligations.
