DSCR (Debt Service Coverage Ratio) — Banking Glossary · BankAI.fyi
Debt Service Coverage Ratio — cash available to service debt ÷ total debt service due. DSCR below 1.0x means the borrower can't service debt from operations.
What is DSCR?
DSCR = Net Operating Income (or EBITDA) ÷ Total Debt Service
Where Total Debt Service = Principal repayment + Interest due in the period.
A DSCR of 1.5x means the borrower generates ₹1.50 for every ₹1.00 of debt repayment due. A DSCR below 1.0x means the borrower cannot service its debt from operations — a critical red flag.
Why credit analysts live and breathe DSCR
In project finance, SME lending, and infrastructure credit, DSCR is often the primary underwriting metric. It tells you:
- Can this borrower repay from its own cash flows?
- How much buffer exists if revenue falls (downside sensitivity)?
- What is the break-even revenue level before debt service is impaired?
Typical DSCR benchmarks in Indian banking
| Loan Type | Minimum DSCR (typical) |
|---|---|
| Project finance (infra) | 1.3x–1.5x |
| SME term loan | 1.25x–1.5x |
| Commercial real estate | 1.35x–1.5x |
| Working capital (approximated) | 1.1x–1.2x |
RBI’s project finance guidelines require lenders to stress-test DSCR under base, moderate, and severe scenarios.
How DSCR is calculated — a practical example
Borrower: A mid-size textile manufacturer
Revenue: ₹120 Cr
EBITDA: ₹24 Cr (20% margin)
Annual debt service: ₹15 Cr (₹10 Cr principal + ₹5 Cr interest)
DSCR = ₹24 Cr ÷ ₹15 Cr = 1.6x ✅
Now stress-test: if revenue drops 20%
Stressed EBITDA: ₹18 Cr
Stressed DSCR: ₹18 Cr ÷ ₹15 Cr = 1.2x — still above 1.0x, but thin.
Common DSCR traps in credit analysis
Trap 1: Using reported EBITDA vs. free cash flow
EBITDA excludes capex. For capital-intensive businesses (manufacturing, infrastructure), use cash EBITDA minus maintenance capex as the numerator.
Trap 2: Front-loaded repayment schedules
A borrower might have 1.5x DSCR today but a ballooning principal repayment in year 3. Always map DSCR year-by-year across the loan tenor.
Trap 3: DSCR from audited vs. management accounts
SME borrowers often show better numbers in management accounts. Demand audited financials and independently verify revenue from GST filings, bank statements, and debtor lists.
Trap 4: Ignoring subsidiary / group level debt
If the borrower has guaranteed debt at a subsidiary or has pledged group assets, the effective debt service burden is higher than the standalone DSCR suggests.
DSCR in the context of RBI’s new project finance framework
RBI’s revised project finance guidelines (consulted in FY25) tightened DSCR requirements and mandatory stress-testing across all lenders. Credit teams in infrastructure lending must now maintain documented evidence of:
- Base case DSCR above 1.3x
- Moderate stress DSCR (revenue -15%) above 1.1x
- Severe stress DSCR (revenue -25%) above 1.0x
This has meaningfully increased the documentation burden for project finance credit papers.
