How the debt service coverage ratio decides term loan sanction

In term loan and project finance appraisal, the debt service coverage ratio is the one number that decides whether a proposal is bankable or merely profitable on paper. A borrower can show healthy sales and a comfortable current ratio and still be unable to pay an instalment on the due date, because profit is an accounting concept while repayment is a cash event. This guide walks a Certified Credit Professional candidate through the computation, the acceptable bands, the structuring decisions the ratio drives, and the traps that examiners love to set around it.

📊 What the Debt Service Coverage Ratio Actually Measures

The ratio answers a narrow question: out of the cash a unit generates in a year, how many times over can it meet that year's obligation on term debt? It is therefore a cash-flow adequacy test for long-term borrowing, not a liquidity test and not a profitability test. Working capital limits are assessed through turnover, holding levels and drawing power; term debt is assessed through this ratio.

Two features make it different from most balance-sheet ratios. First, it is computed year by year across the entire repayment period, not once at sanction. A ten-year term loan produces ten separate figures plus an average. Second, it is built from projected financials, which means the credit officer is really testing the credibility of the projections, not the arithmetic.

The numerator is cash accrual available for servicing debt — profit after tax plus depreciation plus other non-cash charges, plus interest on the term loan when the gross form is used. The denominator is that year's debt service: interest on the term loan plus the principal instalment falling due. Interest on working capital is never included, because it is an operating cost already absorbed in arriving at profit.

Understanding this cash-versus-profit distinction is also the foundation of cash flow based lending, where the same logic is applied to shorter-tenor, data-driven exposures. Candidates should revise the fundamentals in Credit Appraisal Part 1 before attempting numerical questions on this topic.

🧮 Gross DSCR and Net DSCR: The Two Formulas

Banks use two forms, and the exam frequently tests whether you can tell them apart. The gross form treats interest on the term loan as part of the obligation being serviced, so it is added back in the numerator and included in the denominator:

• Gross DSCR = (PAT + Depreciation + Other non-cash charges + Interest on term loan) ÷ (Interest on term loan + Principal instalment)
• Net DSCR = (PAT + Depreciation + Other non-cash charges) ÷ (Principal instalment)

The net form drops interest from both sides on the reasoning that interest has already been charged to the profit and loss account and the real question is whether residual accruals can retire principal. Net DSCR is always the harsher of the two in the early years of a loan, when the interest component is heavy.

Two adjustments are commonly missed. Items such as amortisation of preliminary expenses, deferred revenue expenditure written off and provisions that involve no outflow are added back. Dividend paid, drawings by partners and any cash outflow to owners are not added back — they reduce the cash available for the lender.

💡 Exam Tip: If a question gives you interest on cash credit separately, exclude it from both numerator and denominator. Only term loan interest enters the gross computation.

Where the borrower is a group entity or a special purpose vehicle, the analyst must confirm whose cash flows are being counted. The permissible structures and the borrower types that a bank may lend to are covered in Types of Borrowers & Types of Credit Facilities - Part 1.

📈 Benchmarks, Averages and the Minimum-Year Test

No single number is universally mandated; each bank fixes the floor in its loan policy, and the floor varies by sector, tenor and construction risk. The bands below reflect the ranges most commonly applied in Indian commercial banking practice.

The crucial discipline is that a healthy average never rescues a deficient year. A proposal averaging 1.80 but dipping to 0.90 in year three is a proposal that defaults in year three. The correct response is not rejection and not a higher rate; it is re-laddering the repayment schedule — a longer moratorium, step-up instalments, or a ballooned final tranche — so that every year clears the floor.

📌 Remember: A high average DSCR with one sub-1.00 year is a structuring failure, not a rejection. Fix the ladder before you fix the price.

⚠️ Sensitivity Analysis and Where Appraisals Go Wrong

Because the ratio is built entirely from projections, it is only as honest as the assumptions feeding it. Sensitivity analysis re-runs the computation after stressing the two or three variables that actually move the cash flow — typically selling price, capacity utilisation, and the cost of the main raw material. A project that stays above 1.00 after a ten per cent adverse move on each is genuinely resilient; one that collapses is a project whose base case was engineered to clear the floor.

The recurring errors in appraisal notes are predictable. Analysts capitalise interest during construction and then forget to include the enlarged loan in the repayment obligation. They assume full capacity utilisation from year one when the industry norm is a three-year ramp-up. They net off a promoter's unsecured loan as if it were free cash, ignoring that it will be withdrawn. They extend tenor purely to make the ratio look better, without asking whether the asset's economic life supports the extended period.

⚠️ Common Mistake: Stretching the repayment period does raise the annual figure — but a loan tenor exceeding the useful life of the financed asset simply converts a term loan into an evergreen exposure.

Documentation quality matters as much as arithmetic here, since a mis-drafted repayment schedule or an unenforceable security creates exposure that no ratio can capture. Candidates preparing across papers should read the companion note on legal risk in banking. The financial statement inputs themselves come from the borrower's submissions, so the treatment of CMA data in credit appraisal feeds directly into the projections used here.

🏦 Regulatory Context and Post-Sanction Monitoring

Project lending in India now operates under a consolidated framework. The Reserve Bank of India issued the Reserve Bank of India (Project Finance) Directions, 2025, which took effect from 1 October 2025 and harmonise the treatment of under-construction exposures across banks, NBFCs and other regulated lenders — covering date of commencement of commercial operations norms, deferment limits and standard-asset provisioning during the construction phase. The authoritative text and subsequent amendments are on the Reserve Bank of India website, and no appraisal note should quote provisioning rates from memory.

The practical consequence for the credit officer is that the ratio is not a sanction-day formality. Most banks stipulate a covenant requiring the borrower to maintain a specified minimum level, tested annually against audited financials, with a breach triggering a review, additional security or a step-up in pricing. Falling actual coverage is one of the earliest reliable indications that a standard account is drifting.

Monitoring therefore compares each year's actual figure against the projection accepted at sanction. A widening gap — even while the account remains regular through refinancing or promoter infusion — is a warning worth acting on. Where a project has already slipped, resolution options and the sacrifice involved are examined in the note on one time settlement of loans.
