Debt service coverage: Compare operating cash available with required principal and interest payments.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Debt service coverage to answer this question: compare operating cash available with required principal and interest payments? Enter Net operating income and Principal and interest due; the calculator shows Debt service coverage ratio. Try changing one number and watch what happens to Debt service coverage ratio. The answer tells you Debt service coverage ratio.
Age 15Explain it to a 15-year-oldConnect it to the formula
A DSCR above one means the entered operating income exceeds scheduled debt service. Lenders may define eligible income and debt service differently, so use the definitions required by the relevant agreement. The rule is DSCR = Net operating income ÷ total debt service. Its input values are Net operating income, Principal and interest due, and the main result is Debt service coverage ratio. Try changing one number and watch what happens to Debt service coverage ratio.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is DSCR = Net operating income ÷ total debt service, evaluated from Net operating income, Principal and interest due to produce Debt service coverage ratio. A DSCR above one means the entered operating income exceeds scheduled debt service. Lenders may define eligible income and debt service differently, so use the definitions required by the relevant agreement. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
Compare operating cash available with required principal and interest payments.
Why the business model works
A DSCR above one means the entered operating income exceeds scheduled debt service. Lenders may define eligible income and debt service differently, so use the definitions required by the relevant agreement.
Inputs and operating assumptions
This model uses Net operating income, Principal and interest due (at least 0.01). Keep currencies, accounting treatment and time periods consistent with one another.
The formula
DSCR = Net operating income ÷ total debt service
What the calculator produces
The primary output is Debt service coverage ratio; it also exposes Cash cushion after debt service. Change one assumption at a time so the comparison remains explainable.
Before using the result in a decision
This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.
