The debt-service coverage ratio is one of the first numbers a commercial lender checks. This guide explains how DSCR is calculated, why it matters, and what a strong ratio looks like — written for UK limited companies and LLPs seeking business finance.
The debt-service coverage ratio (DSCR) tells a lender whether your business generates enough cash to cover its debt repayments. It answers a simple question: for every pound of loan repayment due, how much operating cash does the company actually produce?
The ratio is expressed as a multiple. A DSCR of 1.0x means the business earns exactly enough to meet its debt obligations, with nothing to spare. Above 1.0x, there is headroom; below 1.0x, the company would need to draw on reserves or other income to keep up. Because it links repayment capacity directly to trading performance, DSCR sits at the centre of most commercial underwriting decisions.
The standard formula divides the cash available to service debt by the total debt payments falling due in the same period:
Worked example: a company with EBITDA of £180,000 and annual debt service (existing plus proposed) of £120,000 has a DSCR of 1.5x. That means it produces £1.50 of cash for every £1.00 of repayment due — comfortable headroom that most lenders view favourably.
A single snapshot of turnover or profit does not show whether a business can sustain repayments. DSCR does. It stress-tests affordability against the actual repayment schedule, which is why it often matters more to an underwriter than headline revenue. A healthy ratio signals a facility that can be serviced comfortably from ordinary trading, not from one-off events or the director's personal resources.
There is no single universal threshold, but commercial lenders generally group ratios into broad bands:
The exact bar depends on the sector, the loan term, and how volatile your revenue is. A business with steady, contracted income may be judged on a lower ratio than one with seasonal or project-based cash flow.
Credicorp is an exempt business lender: we provide credit exclusively to UK limited companies and LLPs, operating outside FCA consumer-credit regulation under Articles 60B and 60L of the FSMA (Regulated Activities) Order 2001. Because we assess the company directly rather than an individual consumer, DSCR is central to how we underwrite. We look at your business's cash generation against the total repayment schedule to confirm a facility is affordable from ordinary trading.
Directors are not asked for a personal guarantee on standard facilities (larger amounts are assessed case-by-case). We use FCA-regulated open-banking connections to read the account data needed for assessment — we never see or store your login credentials. Loan amounts are typically £10k–£500k; rates vary with risk and are shown in your Credicorp Hub before you proceed, with no impact on any personal credit file.
No. Interest cover measures earnings against interest only. DSCR is stricter: it measures cash against both interest and principal repayments, so it reflects the full cost of servicing the debt.
Most use EBITDA or an adjusted net operating income as the cash-generation measure, then divide by total scheduled debt service. Some lenders make further adjustments — for example, adding back non-recurring costs — but the principle is the same.
No. A strong ratio helps, but a lender also considers trading history, sector, the age of the company, filings, and any adverse credit. DSCR is a key input, not the whole decision.
Because we specialise in company lending, our criteria are sharper and our decisions faster than generalist lenders. Our exempt-lending model under FSMA RAO 2001 is designed specifically for incorporated entities, and DSCR-led underwriting reflects that focus.
