What Is Debt Service Coverage Ratio (DSCR)? Formula, Meaning and Example
Learn what Debt Service Coverage Ratio means, how to calculate DSCR, how to interpret the ratio, and why it matters when evaluating a company's debt repayment capacity.
# What Is Debt Service Coverage Ratio (DSCR)?
A company can have profitable operations and still face financial pressure if it cannot comfortably meet its debt obligations.
The Debt Service Coverage Ratio (DSCR) measures how much cash or operating income is available to cover required debt service.
It is especially relevant for businesses with meaningful borrowing, such as infrastructure, manufacturing, real estate and other capital-intensive companies.
DSCR Formula
A commonly used simplified formula is:
DSCR = Cash Available for Debt Service ÷ Debt Service
Debt service generally includes:
The exact numerator and denominator can vary depending on the company, lender and analytical framework. Always check the definition being used.
Simple Example
Suppose:
Total debt service = ₹250 crore
DSCR = ₹500 ÷ ₹250 = 2.0x
In this simplified example, the company has ₹2 of cash available for every ₹1 of scheduled debt service.
How to Interpret DSCR
A DSCR above 1 generally means the measured cash flow is sufficient to cover the defined debt service.
A DSCR below 1 means the measured cash flow is insufficient to cover the defined debt service.
| DSCR | Simplified Interpretation |
|---:|---|
| 0.8x | Does not fully cover debt service |
| 1.0x | Exactly covers debt service |
| 1.5x | 1.5 times coverage |
| 2.0x | Larger coverage cushion |
These are illustrations, not universal rating thresholds.
Why DSCR Matters
DSCR can help investors assess:
A higher DSCR generally provides more room to absorb a temporary decline in cash flow.
DSCR vs Interest Coverage Ratio
These ratios are related but different.
Interest Coverage Ratio primarily focuses on the ability to cover interest expense.
DSCR considers debt service, which can include both interest and principal repayment.
A company may have adequate interest coverage but still face pressure from large principal repayments.

Example: Why Principal Matters
Suppose a company has:
Interest coverage:
₹400 ÷ ₹80 = 5.0x
But DSCR:
₹300 ÷ (₹80 + ₹220) = 1.0x
The company can cover the defined debt service, but there is essentially no cushion in this simplified example.
This illustrates why looking only at interest coverage can miss principal-repayment pressure.
DSCR and Cash Flow
For equity investors, DSCR should be connected with operating cash flow and free cash flow.
A company may show strong EBITDA while cash is tied up in:
Therefore, cash availability matters.

DSCR and Capital-Intensive Businesses
Consider a hypothetical infrastructure company:
DSCR = ₹1,200 ÷ ₹800 = 1.5x
If cash available falls to ₹800 crore:
DSCR = ₹800 ÷ ₹800 = 1.0x
A deterioration in cash flow can therefore materially reduce the safety cushion.
DSCR Trend Is More Useful Than One Number
Suppose a company reports:
| Year | DSCR |
|---|---:|
| Year 1 | 2.2x |
| Year 2 | 1.9x |
| Year 3 | 1.5x |
| Year 4 | 1.1x |
Even though the ratio remains above 1, the trend is deteriorating.

DSCR and Net Debt
DSCR measures debt-service capacity.
Net Debt measures debt after considering cash.
Together they provide a better picture than either metric alone.
A company could have moderate net debt but a near-term repayment schedule that creates pressure.
Frequently Asked Questions
What is a good DSCR?
There is no single universal number. A ratio above 1 indicates coverage under the specific definition used, while a higher ratio generally provides a larger cushion.
Is DSCR the same as debt-to-equity?
No. Debt-to-equity measures leverage relative to shareholders' equity. DSCR measures the ability to cover debt service.
Can DSCR fall even when profit rises?
Yes. Cash flow, working capital, CapEx and debt repayments can change independently of reported net profit.
Do lenders and investors calculate DSCR the same way?
Not always. Definitions of cash available for debt service and treatment of interest, principal, taxes and other items can differ.
Final Thoughts
DSCR answers a practical financial question:
Can the business generate enough cash to meet its scheduled debt obligations?
Use it alongside cash flow, net debt, interest coverage and the debt maturity schedule.
