Most businesses know EBITDA drives debt deal terms, but many underestimate how forensically institutional lenders analyse this metric, leading to costly mistakes in debt structuring and covenant negotiations.
Lenders don't simply accept reported EBITDA figures. They convert EBITDA into Cash Flow Available for Debt Service (CFADS), scrutinise every adjustment through quality of earnings analysis, and spot manipulation attempts that damage management credibility.
Understanding this lender perspective, from EBITDA's role in credit analysis to the technical processes that determine borrowing capacity, reveals why common practices often backfire with sophisticated debt providers.
Despite EBITDA's dominance as the standard credit metric, institutional lenders recognise its inherent limitations and employ a systematic conversion process that transforms reported earnings into Cash Flow Available for Debt Service (CFADS). This technical analysis determines actual borrowing capacity and drives covenant structuring, making the EBITDA-to-CFADS translation the critical calculation that underpins all subsequent lending decisions.
The critical calculation that determines actual borrowing capacity follows a systematic methodology that consistently reduces EBITDA by 15-30% once lenders apply their cash flow adjustments.
The CFADS Calculation Formula
CFADS = EBITDA - Cash Taxes - Working Capital - Maintenance Capex

| Step | Calculation Component |
|---|---|
| 1 | Start with Reported EBITDA |
| 2 | Subtract Cash Tax Payments (actual payments to tax authorities, not accounting provisions) |
| 3 | Subtract Normalised Working Capital investments Requirements (based on sustainable growth assumptions) |
| 4 | Subtract Maintenance Capital Expenditure (required to sustain current operations) |
| Result | Cash Flow Available for Debt Service (CFADS) |
Example Calculation:
With required coverage ratios of 1.25x-1.50x, this £7.0 million CFADS supports maximum annual debt service of £4.7-5.6 million, significantly below what EBITDA multiples might suggest.
This systematic reduction explains why many businesses face unexpected borrowing capacity limitations despite strong reported profitability.
Faced with CFADS reductions, some finance teams attempt to inflate reported EBITDA through aggressive adjustments, but institutional lenders possess sophisticated detection methods that turn these tactics into credibility liabilities.
Institutional due diligence examines month-by-month EBITDA progression and scrutinises individual invoices supporting proposed addbacks. Experienced lenders view excessive adjustments as predictive indicators of future underperformance rather than legitimate normalisation exercises.
Adding back goodwill impairment represents one of the most damaging mistakes when presenting EBITDA to institutional lenders. While technically non-cash, goodwill writedowns signal either overpayment for acquisitions or deteriorating asset performance.
Institutional lenders interpret goodwill addbacks as evidence that management doesn't understand credit analysis or attempts to obscure business deterioration. Either conclusion proves fatal to establishing credibility essential for successful debt raising.
Understanding these institutional lending dynamics enables more effective preparation for debt market engagement, where proper EBITDA positioning proves essential to securing optimal terms.
Effective preparation involves sense-checking the EBITDA-to-CFADS conversion using conservative assumptions and benchmarking against industry-specific covenant structures to establish realistic facility sizing expectations.
Due diligence preparation requires developing coherent narratives around any proposed EBITDA adjustments, with comprehensive documentation that demonstrates operational understanding rather than accounting manipulation.
This systematic approach helps CFOs avoid common credibility traps whilst positioning their businesses effectively within institutional debt markets.
Understanding how institutional lenders forensically analyse EBITDA reveals the technical realities behind debt capacity calculations and explains why common financing assumptions often fall short of market expectations.

Lenders follow a systematic four-step process: Start with reported EBITDA, then subtract cash tax payments (actual payments to tax authorities), subtract normalised working capital requirements (based on sustainable growth assumptions), and subtract maintenance capital expenditure (required to sustain current operations). This typically reduces EBITDA by 15-30%, as shown in our example where £10 million EBITDA becomes £7 million CFADS.
Goodwill impairment signals either overpayment for historical acquisitions or deteriorating asset performance. Institutional lenders interpret these addbacks as evidence that management doesn't understand credit analysis or attempts to obscure business deterioration. This damages the credibility essential for successful debt raising and can have lasting reputational consequences within debt markets.
