Quick answer
Debt service coverage ratio is a rental investing metric that compares net operating income with debt service. Debt service usually means principal and interest payments on a loan. A DSCR above 1.0 means income is greater than debt payments before other owner-specific factors.
Lenders and investors may use DSCR to evaluate whether a rental property appears to support its financing.
DSCR formula
The common formula is:
Net operating income divided by annual debt service equals DSCR.
For example, if a property has $30,000 in NOI and $24,000 in annual debt service, the DSCR is 1.25.
What DSCR tells owners
DSCR helps show how much income cushion exists between operating income and loan payments. A higher DSCR can suggest more room for vacancy, repairs, or income changes.
Loan programs and lenders may set their own DSCR requirements.
What DSCR does not include
DSCR does not tell the full investment story. It may not include income taxes, depreciation, capital improvements, owner cash reserves, future rent growth, or every financing detail.
It should be reviewed alongside cash flow and property condition.
How owners should use DSCR
Owners can use DSCR to compare financing scenarios, evaluate leverage, and understand how sensitive a rental property may be to income or expense changes.
It is a tool for analysis, not a guarantee of performance.
