DSCR: Debt Service Coverage Ratio Explained for Bank Loans

You walk into a bank and ask for ₹60 lakh for your unit. The credit officer opens a worksheet, punches in your projected P&L, and out comes a single number: your DSCR. That number decides whether the file moves forward or dies quietly. This guide explains what it measures, the exact formula Indian banks use, how to compute it year by year, where the famous 1.33 really comes from, and how to run the ratio backwards to size your own loan before you apply. Everything is in ₹ lakh, and the worked example uses a fictional company.

What Is the Debt Service Coverage Ratio?

The debt service coverage ratio measures whether a business generates enough cash in a year to pay its loan obligations that year. Obligations means the full bill: interest plus the principal instalment. A DSCR of 1.5 means the business generates ₹1.50 of cash for every rupee of debt service it owes.

The numerator is your cash accruals. Profit after tax, plus depreciation and other non-cash charges added back, plus interest on the term loan added back. Interest is added back because it is part of what you are measuring against: you want the cash available before servicing debt, then you compare it with the debt service. The denominator is the year’s debt service: the principal instalment plus the interest on the term loan.

Two quick reads on the number. DSCR above 1 means the cash covers the obligation, with room to spare. DSCR below 1 means the business cannot pay the loan from its own cash that year, so it must dip into reserves, borrow more, or default. That is the entire logic of the ratio in one paragraph.

What Formula Do Indian Banks Actually Use for DSCR?

Indian banks mostly use the P&L-based variant above, but at least three other versions float around. Variants can shift the answer by 0.15x to 0.30x, so the formula matters as much as the number. Always ask your bank which worksheet it uses.

The bank variant is the one this article uses throughout. It is the shape you find in Bank of Baroda’s internal credit-risk model document (BOBRAM): (PAT + depreciation + interest) divided by (interest + current portion of long-term debt), with cash flows from operations used rather than profits and non-operating or extraordinary items excluded. IIBF training material uses the same shape and calls an average DSCR of 1.50 “reasonable”. That is training material and one bank’s model, not an industry standard, so treat the shape as the convention and the number as each bank’s own call.

Worked Example: How a Bank Computes DSCR on a ₹60 Lakh Term Loan

Here is a full five-year DSCR computation for a fictional borrower, built the way a credit officer builds it: from the projected P&L and the repayment schedule, year by year.

Setup: Mehta Packaging Pvt Ltd, Indore. ₹60 lakh term loan, 11% p.a., 5 years. The annual instalment is ₹16.23 lakh (the EMI formula: loan × rate ÷ (1 − (1 + rate)^−tenure)). PAT starts at ₹15 lakh and grows 10% a year. Depreciation is ₹6 lakh a year.

Average DSCR is 1.76; the minimum, in year 1, is 1.70. The file clears the usual comfort zone. Notice what the bank looks at: both the average and the weakest year. A file with a healthy average but one year at 0.9 still has a problem, because that is the year the borrower cannot pay. This exact table is in the free workbook below: change the yellow cells and it recalculates everything.

What DSCR Do Banks Look for, and Is 1.33 Really an RBI Rule?

No RBI circular fixes a DSCR floor for a fresh term loan. But the number 1.33 did come from RBI, just from a different job. Here is the actual story.

On May 30, 2013, RBI issued a circular reviewing prudential guidelines on restructuring of advances (DBOD.BP.BC.No.99/21.04.132/2012-13). Its appendix, “Broad benchmarks for the viability parameters”, said this, verbatim: “The debt service coverage ratio should be greater than 1.25 within the 5 years period in which the unit should become viable and on year to year basis the ratio should be above 1. The normal debt service coverage ratio for 10 years repayment period should be around 1.33.”

That was a viability test for restructured, stressed accounts: is this sick unit worth saving? It was never a sanction norm for fresh loans. Note the wording too: “should be greater than”, “should be above”, “should be around”. Not “shall”, not mandatory. Over the years, bankers carried the number from stressed-account work into everyday appraisal, and 1.33 became folklore.

Meanwhile, RBI’s own language for fresh lending is deliberately soft. The Master Circular on IRAC norms, para 4.2.15, says only that the revised DSCR “should be acceptable to the lenders”: a discretion test, no number. And the February 2014 circular on the Joint Lenders’ Forum lists DSCR as one of the “illustrative” viability parameters, with benchmarks “determined by” the lenders themselves. In short: RBI recognises the ratio and leaves the number to the bank.

So what do banks actually use? In practice, 1.25 as a floor and 1.33 to 1.50 as comfort, with project finance stretching to 1.50 and above. IIBF training material calls an average DSCR of 1.50 “reasonable”. But every bank’s credit policy sets its own number, and sectors differ. The binding document is your sanction letter. Ask for the threshold in writing before you apply, and you will never argue about folklore again.

How Can You Size a Loan With Reverse DSCR?

Most borrowers use DSCR forward: given a loan, do I clear the threshold? The more useful direction is backwards: given my cash flows and the bank’s threshold, what is the maximum loan I can carry? RBI itself thinks this way. The same 2013 appendix defines the Loan Life Ratio as the present value of cash flows divided by the maximum loan amount, with a benchmark of 1.4: a 40% cushion on the loan, computed from cash. Reverse DSCR is the same instinct, applied to your own numbers.

Step 1: find the maximum annual debt service. Divide your projected annual cash accruals by the threshold. Cash accruals of ₹24 lakh a year and a 1.33 threshold give ₹24 ÷ 1.33 = ₹18.05 lakh a year of serviceable debt.

Step 2: convert the annual service into a loan amount. An annual payment supports a loan equal to the payment times the annuity factor: (1 − (1 + rate)^−tenure) ÷ rate. At 11% over 5 years the factor is 3.6959, so ₹18.05 lakh a year supports ₹18.05 × 3.6959 = ₹66.69 lakh.

The sensitivity is the point. The same ₹24 lakh of cash accruals supports ₹70.96 lakh at a 1.25 threshold and only ₹59.13 lakh at 1.50: the threshold moves the answer by nearly ₹12 lakh. And the math closes its own loop: take the ₹66.69 lakh loan at 11% over 5 years, and its annual service is ₹18.05 lakh, so DSCR = 24 ÷ 18.05 = 1.33, exactly the threshold. The Reverse Sizing tab of the workbook does all of this with visible formulas, so you can check every step.

Where Does DSCR Sit in a CMA Report?

DSCR sits in the Ratio Analysis block of the CMA, and it is computed on your projected years, not just on history. The IBA-format CMA has seven statements; the sixth is the ratio block, carrying the current ratio, DSCR, and TOL/TNW. Your projected P&L builds the numerator (projected PAT, projected depreciation), and the proposed repayment schedule builds the denominator. That is why a weak projection breaks two things at once: the projected profits look thin and the DSCR collapses. Our CMA data guide walks through the full format, and the MPBF guide covers the working-capital half of the same appraisal.

DSCR vs ICR vs FOIR: Which Ratio Answers Which Question?

Three ratios, three different questions. Confusing them is how borrowers walk in confident and walk out rejected.

The one-line illustration practitioners use: a company can show a strong 3x ICR and only 1x DSCR, because principal is usually the larger part of the cash outflow. That is exactly why a credit officer never stops at ICR for a term loan. FOIR is the retail lens (salary versus EMIs); DSCR is the business lens (operating cash versus debt service). If you are a company applying for a term loan, DSCR is the ratio that decides your file.

What Drags DSCR Down, and How Do You Fix a Low One?

A low DSCR traces to one of four levers. Find the lever before you touch the numbers.

• Profits too thin. The numerator starts with PAT. If margins are weak, no repayment structure fixes the ratio. Improve the operating story first.
• Interest too high. A cheaper rate or a longer tenure cuts the denominator directly. Run the reverse-DSCR math at two rates before negotiating.
• Principal too bunched. Heavy early instalments crush the first years. A longer tenure, a moratorium, or a balloon structure spreads the load.
• One-off hits in the year. A genuine non-recurring expense can be legitimately adjusted, but the bank will want proof, and your bank statements must agree with the story.

One thing you must not do: inflate the projections to manufacture the ratio. Banks back-test your projections against your last three years of financials and your bank statements, and a DSCR built on fantasy projections is how files get rejected or, worse, flagged. A DSCR sliding below 1 for two running years is exactly the kind of input that feeds a bank’s early warning system. Build the ratio on numbers you can defend, then use the workbook to find the biggest loan those numbers honestly support. For the full picture of how a bank judges your file, see our CAM guide; if you also hold working capital, the drawing power and stock audit guides cover the other half of your limits.

Where Can I Download the DSCR Calculator Workbook?

The workbook has three sheets. Forward DSCR runs the five-year Mehta Packaging computation with your own numbers: yellow input cells, every result a visible formula, average and minimum DSCR, and a PASS/REVIEW verdict against your bank’s threshold. Reverse Sizing turns your cash accruals and a threshold into a maximum loan amount with the annuity math, plus a sensitivity table across 1.25, 1.33, and 1.50. The Checks sheet reconciles everything with four PASS/FAIL formulas.
