DSCR: What It Is, How to Calculate It, and Why It Decides a Loan
The DSCR (Debt Service Coverage Ratio) divides a period’s operating cash flow by that same period’s total debt service, principal plus interest. A DSCR of 1.25x means cash flow exceeds the payment by 25%.
En resumen
- The DSCR divides a period's operating cash flow by that same period's debt service, principal plus interest.
- It reads as a multiple: above 1.0x the company generates more cash than it needs to pay; below 1.0x it depends on an external source.
- The most common reference threshold in commercial banking is 1.25x — 25% headroom over the payment.
- The most frequent mistake is including only interest in the denominator: that inflates the ratio and makes a tight operation look comfortable.
- Project finance with long-term contracts accepts lower coverage; cyclical sectors require higher coverage.
What Is the DSCR?
The DSCR measures how many times a company's cash flow covers a period's debt payment. It's the indicator that turns the credit committee's question — can this company pay? — into a number. Unlike balance-sheet ratios, which are a snapshot in time, the DSCR compares two flows from the same period.
DSCR = Operating Cash Flow ÷ Debt Service
Both terms must correspond to the same period: annual with annual, monthly with monthly.
Debt service includes principal plus interest. That detail is the one most often gotten wrong: using interest alone inflates the ratio and makes a tight operation look comfortable.
How Is the Result Interpreted?
The DSCR reads as a multiple. Above 1.0x the company generates more cash than it needs to pay; below that, it falls short and depends on another source — refinancing, shareholder contributions, asset sales — to meet the payment.
| DSCR | Reading | What it implies |
|---|---|---|
| Below 1.0x | Cash flow does not cover the payment | The operation doesn't pay for itself. Requires an identified, committed external source. |
| 1.0x to 1.20x | Coverage with no headroom | Any minor dip in sales or collections leaves the company without cash for the payment. |
| 1.25x to 1.50x | Adequate coverage | Typical approval range in commercial banking for established companies. |
| Above 1.50x | Ample coverage | Headroom to absorb an adverse scenario without compromising payment. |
The 1.25x threshold is the most widespread reference in commercial banking, and it's the default value CreditIQ uses when configuring covenants. It's not a universal rule or a regulation — what actually is regulated is how a bank classifies and provisions the loan, defined by the risk standards of the Basel Committee and, in Chile, by CMF regulation. Project finance with long-term contracts accepts lower coverage because cash flow is more predictable, and cyclical sectors require higher coverage.
How to Calculate It Step by Step
Calculating a DSCR is three steps: turning EBITDA into real operating cash, building the period's full debt service — principal plus interest on every loan, including the one being evaluated — and dividing the first by the second. Most of the work is in the first step, and that's where the mistakes concentrate.
1. Determine operating cash flow
The usual starting point is EBITDA, since it approximates the cash the operation generates before financial structure and taxes. But EBITDA isn't cash — it has to be adjusted.
- Subtract taxes actually paid during the period.
- Subtract or add the change in working capital: growing receivables and inventory consume cash.
- Subtract replacement capex — what the company needs just to keep operating.
- Exclude one-off income and expenses that won't repeat.
2. Determine debt service
Add up every principal repayment and every financial expense due within the period, including the loan being evaluated. If the new loan is disbursed mid-year, only the installments that actually fall within the period should be reflected.
3. Divide and project
A historical DSCR tells you whether the company could pay what it already had. What decides the deal is the projected DSCR, which incorporates the new debt. That's why the calculation always runs on the cash flow projection, period by period rather than as an average: an annual average of 1.3x can hide two months at 0.7x.
What Mistakes Are Made When Calculating It?
Using raw EBITDA as cash flow. It's the most common simplification and the most dangerous one. A company with rising EBITDA and working capital eating cash shows an apparent DSCR much higher than the real one.
Leaving out principal repayment. Dividing by interest alone doesn't give you a DSCR — it gives you interest coverage, a different and considerably more forgiving ratio.
Averaging the year. A seasonal business can meet the covenant on aggregate and still have no cash right in the month of the large payment.
Forgetting the debt being evaluated. The relevant DSCR is the one after the deal, not before it.
How CreditIQ Calculates It
CreditIQ calculates the DSCR on the loaded financial statements, period by period and already adjusted for working capital, with no spreadsheet to build. The risk analysis engine feeds it into the score, the stress-test module recalculates it under adverse scenarios, and the covenant module tracks it against the agreed threshold and flags periods in breach.
