What is DSCR? Debt Service Coverage Ratio, explained

Every term loan appraisal I have sat through — and I have arranged over ₹440 Cr in facilities — comes down to one number before anything else. Not the promoter's net worth. Not the collateral value. It is DSCR: the Debt Service Coverage Ratio. If DSCR doesn't clear the bank's threshold, the rest of the credit note is decoration.

Yet I find that even finance professionals who regularly interact with banks aren't always precise about what DSCR is actually measuring, how it is computed, or why lenders weight it so heavily. This piece gives you the full picture — formula, worked example, interpretation, and practical levers to improve it.

What DSCR is

DSCR is the ratio a lender uses to answer one question: does this business generate enough cash from operations to service its debt — principal repayment plus interest — in a given period, without relying on refinancing or asset sales?

It is not a profitability measure. A company can be profitable on paper and still have a DSCR below 1.0 if its depreciation is low, its capex is high, or its principal repayments are front-loaded. DSCR is explicitly a cash flow adequacy test.

"Can this business pay us back from operations — not from refinancing, not from asset liquidation, not from a fresh equity raise? That is what DSCR is asking."

This is why banks model DSCR year by year over the entire loan tenure, not just for the first year. A business might look comfortable in year one and deteriorate sharply in year three when the moratorium ends and full repayments kick in.

The formula

At its core:

DSCR = Cash Available for Debt Service ÷ Total Debt Service

Both terms need to be defined carefully, because this is where variants creep in.

Cash available for debt service (the numerator)

The numerator captures the cash the business generates from operations before debt service payments are made. The most common proxy is EBITDA (Earnings Before Interest, Tax, Depreciation and Amortisation). Some banks use PAT + Depreciation + Interest (which nets back to EBITDA adjusted for tax), and project finance lenders often use net operating cash flow directly from the cash flow statement.

In practice, the starting point in most Indian CMA data packages is EBITDA or cash accrual (PAT + depreciation), with interest added back to arrive at cash available before debt service. The precise definition should be agreed with your banker at the term sheet stage — because if they are using a different numerator than you, you will have an uncomfortable surprise at sanction.

Total debt service (the denominator)

Debt service means interest charges for the period plus scheduled principal repayments due in that period. Both are mandatory outflows — the business has no discretion over either once the loan is drawn. If you have multiple facilities — a term loan, a WCDL, an ECLGS tranche — the denominator includes repayment obligations across all of them in that year.

A worked example

Let's make this concrete. Suppose a manufacturing company has the following financials for a given year:

• EBITDA: ₹6.00 Cr
• Annual interest on term loan: ₹1.20 Cr
• Annual principal repayment: ₹2.80 Cr
• Total debt service: ₹1.20 Cr + ₹2.80 Cr = ₹4.00 Cr

DSCR = ₹6.00 Cr ÷ ₹4.00 Cr = 1.50x

What does 1.50x mean in plain terms? For every ₹1 of debt obligation — interest and principal combined — the business generates ₹1.50 of cash. The ₹0.50 of headroom is the cushion the bank is relying on: it covers unexpected revenue shortfalls, working capital spikes, or cost overruns without the business missing a repayment.

If EBITDA dropped to ₹4.00 Cr, DSCR would be exactly 1.0x — the business is just covering its obligations with zero margin. Drop further to ₹3.5 Cr and DSCR falls to 0.875x, meaning the business cannot service its debt from operations alone. That is a red flag in any appraisal.

Interpreting the number

Lenders do not treat DSCR as a single data point — they read it in bands:

• Below 1.0x: The business cannot cover its debt from cash flows. This is a structural red flag. The bank will either decline or require significant credit enhancement — additional collateral, promoter guarantee, or equity infusion.
• 1.0x – 1.25x: Technically covering obligations, but the cushion is thin. Any revenue softness or cost spike will breach coverage. Banks tend to be uncomfortable here for new facilities; it might be acceptable for a covenant waiver on an existing loan with a strong track record.
• 1.25x – 1.50x: The standard minimum for most term loan sanctions in India. Most PSU banks and private sector lenders set their internal hurdle in this range. At 1.25x or above, the lender has reasonable confidence that moderate business volatility won't impair repayment.
• 1.50x – 2.0x: Comfortable. Gives the bank room to absorb shocks. Borrowers in this range typically get better pricing and fewer restrictive covenants.
• Above 2.0x: Strong. The debt is clearly well-covered by operations. At this level, a business often has negotiating power on rate and tenor.

Average DSCR vs minimum-year DSCR

Banks don't just compute DSCR for one year. In the CMA data or project report, they model it for every year of the loan tenure — typically matching the financial projections submitted by the borrower. Two metrics emerge from this:

• Average DSCR: The mean across all years of the repayment schedule. This gives a sense of the overall coverage over the life of the loan.
• Minimum-year DSCR: The lowest DSCR in any single year of the tenure. This is often the year when repayments ramp up (after a moratorium) or when revenue is projected to dip. The minimum-year figure is the one that actually matters for credit risk — a high average with one bad year is not a clean credit.

I have seen deals where the average DSCR was a comfortable 1.6x but the minimum year — the first full repayment year after moratorium — was 1.08x. The bank flagged it. The structure had to be reworked: the moratorium was extended and repayments were back-loaded slightly to smooth the year-by-year profile.

Gross DSCR vs net DSCR

There is a variant worth knowing. Some lenders compute what is sometimes called gross DSCR — where interest is excluded from the denominator, because interest is already implicitly covered before EBITDA is struck (since EBITDA is pre-interest). In this version, the denominator is only the principal repayment. This gives a higher ratio for the same business and is a more generous measure.

The more common version — and the one I use by default — keeps interest in the denominator alongside principal, giving you the net DSCR as described above. Before running or presenting DSCR numbers to a banker, confirm which definition they are using. It matters more than it should, because the same business will look meaningfully different depending on the convention.

How to improve DSCR

If your projected DSCR is below the lender's threshold, you have several levers — some on the numerator side, some on the denominator side:

Reduce annual debt service (denominator)

• Longer tenor: Spreading repayments over more years reduces the annual principal instalment. A ₹20 Cr loan repaid over 5 years has ₹4 Cr of annual principal; spread over 7 years, that drops to ~₹2.86 Cr. The interest cost rises marginally, but the DSCR benefit is usually worth it in the early years.
• Moratorium: A principal moratorium in the first 12–18 months (common in project finance and greenfield debt) removes principal from the denominator entirely during that window, giving the business time to ramp up EBITDA before repayments begin. Interest still runs, but only interest in the denominator is a much lighter burden.
• Lower interest rate: Reduces both the interest component of the denominator and directly helps the numerator (since interest is a P&L charge). Even 50 bps on a ₹50 Cr term loan is ₹25 lakh per annum — which, depending on your EBITDA level, could move DSCR by 0.05–0.10x.
• Balloon or bullet structuring: Deferring a portion of principal to a bullet payment at the end of the tenor reduces annual repayments during the term. Banks are not always enthusiastic about this (it concentrates refinancing risk), but it is a negotiable tool, particularly for assets with back-loaded cash flows.

Grow cash available for debt service (numerator)

• Higher EBITDA: Revenue growth, margin improvement, cost rationalisation — any of these directly improves the numerator. If projections are conservative and the business has a credible case for higher operating leverage, rebuilding the financial model with revised assumptions can move the needle.
• Equity infusion: Bringing in equity to partially repay debt reduces the outstanding principal, which lowers annual repayments and improves DSCR. It also signals promoter confidence to the bank, which has softer but real credit benefits.

Where DSCR shows up

Once you know to look for it, DSCR appears across every meaningful credit document:

• Term loan sanctions: The sanction letter will specify the minimum DSCR covenant — typically ≥1.25x — to be maintained throughout the tenure. A breach triggers a covenant violation, which can lead to accelerated repayment demands or facility cancellation.
• Project finance appraisals: The entire debt sizing exercise in project finance is structured around achieving a minimum DSCR — you don't lend more than the cash flows can support at a given threshold.
• CMA data (Credit Monitoring Arrangement): The standard three-year historical and three-year projected financial package submitted to banks. DSCR is one of the key ratios computed in the projected statements, year by year.
• ECLGS and WCDL appraisals: Even working-capital-adjacent instruments that have a repayment structure — like ECLGS tranches or working capital term loans — will have a DSCR computed, often using a simplified cash accrual figure.

DSCR is about cash, not profit

The most important thing to internalise about DSCR is what it is not. It is not a profitability ratio. A business with strong PAT can still have a poor DSCR if its tax cash outflows are heavy, its principal schedule is aggressive, or it is consuming cash in working capital faster than it is generating it in EBITDA. Conversely, a capital-intensive business with modest PAT can have a decent DSCR because depreciation — a non-cash charge — is added back in the numerator.

This is why banks ask for DSCR and not just return on equity or net margin. Margin tells you how well the business is trading. DSCR tells you whether the business will actually be able to hand cash back to the lender on schedule — which is, ultimately, the only question a lender is paid to care about.

If you are going into a credit discussion, model the DSCR before your banker does. Year by year, across the full tenure. Know your minimum year. Know whether you are above or below the covenant threshold, and if below, know exactly which lever — tenor, moratorium, rate, or equity — gives you the most efficient path to compliance. That preparation is the difference between a clean sanction and a drawn-out negotiation.
