How Lenders Calculate Debt Capacity for Private Credit Loans

Debt capacity is the amount of borrowing a lender believes a company can support based on its earnings, cash flow, existing obligations, collateral, liquidity and ability to continue servicing debt if operating performance weakens.

For a company raising private credit, debt capacity can determine the maximum facility size before discussions about pricing, maturity, covenants or documentation begin. Management may request US$30 million, while the lender's underwriting supports only US$20 million. Another lender may reach a different result because it uses a different EBITDA calculation, leverage threshold, collateral methodology or downside case.

Understanding how lenders calculate debt capacity for private credit loans helps companies structure financing requests around amounts institutional lenders can realistically underwrite.

What Is Debt Capacity?

Debt capacity is an underwriting conclusion rather than a number selected by the borrower. A company may need US$50 million for an acquisition or expansion, but the financing amount ultimately available depends on what lenders believe the business can repay.

The lender considers whether the borrower can pay interest, meet required principal amortization, fund normal operations, absorb changes in working capital and still maintain an acceptable liquidity cushion.

Private credit lenders can often provide structures outside conventional bank parameters. These may include unitranche debt, delayed-draw term loans, senior secured facilities, second-lien loans or other customized structures. That flexibility still requires an underwritable repayment case.

Companies considering institutional financing can review Financely's private credit advisory coverage for broader information on private lender structures.

The Main Factors That Determine Debt Capacity

Step 1: Determine Normalized EBITDA

For many middle-market private credit facilities, normalized EBITDA is the starting point for debt capacity analysis.

The lender may not accept management's reported adjusted EBITDA without review. Historical financial statements are analyzed to determine which adjustments are genuinely nonrecurring and which costs remain part of the normal operation of the business.

Assume a company reports EBITDA of US$8 million and adds back US$2 million of restructuring expenses, professional fees and projected savings. Management presents adjusted EBITDA of US$10 million.

If the lender accepts only US$750,000 of those adjustments, the lender's underwritten EBITDA becomes US$8.75 million. That difference immediately changes the amount of debt the lender may support.

Typical areas of review can include owner compensation, transaction expenses, litigation costs, restructuring charges, acquisition synergies, discontinued operations, temporary staffing expenses and other proposed add-backs.

Lenders also examine EBITDA quality. A company with recurring contracted revenue and stable margins can receive different treatment from a business with volatile project revenue or significant customer concentration.

Step 2: Apply a Debt-to-EBITDA Multiple

Once normalized EBITDA is established, lenders may apply a leverage ceiling.

Suppose a lender underwrites EBITDA at US$10 million and considers 4.0x total leverage acceptable. The simplified maximum debt amount would be US$40 million.

If the borrower already has US$12 million of debt that will remain outstanding, preliminary incremental debt capacity could be approximately US$28 million.

This calculation provides only an initial ceiling. The company must still demonstrate that it generates enough cash to service the proposed facility.

Step 3: Test Interest Coverage

A leverage multiple can indicate how much debt a lender might consider, but it does not prove that the borrower can afford the resulting interest expense.

Lenders therefore analyze interest coverage using earnings or cash flow relative to cash interest.

A company could appear capable of supporting US$30 million based on leverage but produce inadequate coverage if the facility carries high pricing. This becomes particularly relevant in private credit where customized structures can carry materially higher financing costs than traditional senior bank debt.

If the leverage calculation supports US$30 million while the minimum interest coverage requirement supports only US$24 million, the lender may size the transaction closer to US$24 million.

Debt capacity is therefore commonly constrained by whichever underwriting test produces the lowest acceptable facility amount.

Step 4: Calculate Fixed Charge Coverage

Interest expense is only one demand on company cash flow.

A fixed-charge analysis can incorporate scheduled principal payments, lease obligations, taxes and other recurring commitments. This provides a more complete view of the borrower's ability to service debt while continuing normal operations.

Two companies with identical EBITDA can therefore have very different debt capacities. One may operate a capital-light business with limited fixed obligations, while another requires substantial equipment leases, maintenance expenditure and working capital.

Step 5: Convert EBITDA Into Free Cash Flow

Private credit lenders ultimately need repayment in cash. EBITDA is therefore reconciled to free cash flow.

The analysis can deduct cash taxes, capital expenditure, working-capital investment and other recurring cash requirements. Companies with large receivables balances, inventory requirements or recurring capital expenditures can produce substantially less free cash flow than headline EBITDA suggests.

Consider a company producing US$12 million of EBITDA but requiring US$4 million of annual capital expenditure and another US$2 million of working-capital investment. Its practical debt service capacity may be materially lower than that of a capital-light company generating the same EBITDA.

This is one reason lenders often request monthly working-capital information rather than relying only on annual income statements.

Step 6: Measure Liquidity After Closing

A financing structure also needs to leave sufficient liquidity inside the business.

A company should not use every available dollar of cash to fund an acquisition, refinance debt or complete a capital expenditure program if doing so leaves no cushion for payroll, suppliers, taxes or unexpected operating needs.

Lenders may therefore require a minimum cash balance, revolving facility or another liquidity reserve.

Seasonal businesses require additional analysis. A borrower could show adequate year-end liquidity while experiencing substantial cash requirements during peak inventory or production periods.

Step 7: Review the Existing Capital Structure

Current debt obligations directly affect how much additional private credit a company can raise.

Companies with several layers of debt may benefit from broader debt advisory for middle-market companies before launching a private credit process.

Step 8: Determine Collateral Support

Debt capacity does not always depend primarily on EBITDA.

Companies with significant receivables, inventory, equipment, real estate or other assets may qualify for financing based partly on collateral value. An asset-based lender can calculate availability using eligible collateral and advance rates rather than relying principally on a leverage multiple.

For example, a company with US$40 million of eligible receivables could potentially support a substantial revolving facility even where its EBITDA would not justify the same amount as a conventional cash-flow term loan.

This is why the choice of financing structure matters. A borrower that exceeds the leverage appetite of conventional private credit lenders may still have financing options through asset-based lending, receivables finance or another structured credit solution.

Step 9: Run a Downside Case

Lenders rarely calculate debt capacity solely against management's base-case forecast.

The lender can reduce projected revenue, EBITDA or margins and determine whether the borrower remains capable of servicing the proposed facility.

A downside case may also assume slower customer collections, higher input costs, increased interest expense or delayed growth initiatives.

The objective is to determine how much financial headroom exists before liquidity becomes constrained or covenant compliance becomes difficult.

Debt Capacity for Acquisition Financing

Acquisition financing adds additional underwriting because the lender needs to evaluate the capital structure of the combined business after closing.

The analysis normally includes purchase price, target EBITDA, debt being refinanced, transaction expenses, buyer equity, expected synergies and the proposed financing structure.

Assume an acquisition has an enterprise value of US$75 million and the target generates US$12 million of lender-underwritten EBITDA.

If a lender supports 4.0x total leverage, theoretical debt capacity would be approximately US$48 million. The buyer would then need sufficient equity or another capital layer to fund the remaining purchase price and transaction expenses.

A sponsor seeking greater leverage may combine senior debt with mezzanine financing, preferred equity or another form of structured capital, although the additional financing cost must still fit within the company's cash-flow capacity.

Acquisition sponsors can also review Financely's independent sponsor financing coverage for broader information on acquisition debt structures.

Debt Capacity for Refinancing Transactions

Refinancing debt does not automatically mean a lender will replace the existing principal amount dollar for dollar.

A company may have borrowed during a period of stronger financial performance. If EBITDA subsequently falls, the amount that a new lender can support may be lower than the debt currently outstanding.

Conversely, a company that has grown substantially since its last financing may be able to refinance existing debt while raising incremental capital.

A refinancing analysis therefore compares current debt with updated EBITDA, cash flow, collateral value, liquidity and lender leverage requirements.

Different Lenders Can Produce Different Debt Capacity Numbers

Debt capacity is often a range rather than one universally accepted figure.

One lender may accept US$10 million of EBITDA while another underwrites US$9 million. One may tolerate 4.5x leverage while another prefers 3.5x. An asset-based lender may focus heavily on collateral while a cash-flow lender focuses primarily on enterprise value and free cash flow.

Lender selection therefore affects the amount and type of debt available.

A private credit fund specializing in sponsor-backed acquisition loans may view a transaction differently from a special situations lender, commercial bank or asset-based finance provider.

Documents Needed for Debt Capacity Analysis

A lender-ready transaction also requires an organized supporting file. Financely's private credit data room buildout service addresses the financial and transaction documents lenders typically review during underwriting.
