Definition
DSCR compares cash available to debt obligations (principal + interest). Lenders use it to assess repayment capacity.
Formula
DSCR = cash available for debt service / total debt service
How to use it
- DSCR is more cash-oriented than interest coverage because it includes principal.
- Run scenarios: DSCR can fall quickly when revenue drops or collections slow.
Why this matters
This term matters because cash timing and risk are usually the difference between a plan that works on paper and a plan that survives. Use consistent definitions so decisions are comparable over time.
Practical checklist
- Write a 1-line definition for "DSCR (Debt Service Coverage Ratio)" that your team will use consistently.
- Keep the time window consistent (weekly/monthly/quarterly) when comparing trends.
- Segment results (channel/plan/cohort) before drawing big conclusions from blended averages.
- Sanity-check with a related calculator from the same category on MetricKit.
- Read the related guide (e.g., Loan amortization: how monthly payments and total interest work) for context and common pitfalls.
