Debt service coverage ratio calculator

Estimate debt service coverage ratio from annual net operating income or cash flow and annual debt service.

Result

1.36x

Estimated debt service coverage ratio based on annual income or cash flow divided by annual debt service.

DSCR1.36x

Annual income or cash flow$125,000

Annual debt service$92,000

InterpretationCoverage comfortably above debt service

$125,000 divided by $92,000 produces a DSCR of about 1.36x.
A result above 1.00x means the annual income entered is higher than the annual debt service.
Lenders often layer in different reserve, vacancy, or underwriting rules, so use this as a quick screening metric rather than a final approval benchmark.

This is a planning estimate only. Real lender requirements, reserve rules, and underwriting adjustments can all change how DSCR is evaluated.

How it works

What the calculator is doing

Enter annual net operating income or annual cash flow and annual debt service.

The calculator divides annual income by annual debt service to estimate DSCR.

It also shows a plain-language interpretation so the result is easier to scan quickly.

Understanding your result

DSCR is a useful screening metric, but it is not a final approval standard. Lenders can define acceptable coverage differently, and real underwriting may also adjust income, reserves, vacancy assumptions, or debt treatment.

Examples

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Screen a rental or property deal quickly

A quick DSCR estimate can help show whether annual cash flow appears to cover the annual debt load before a deeper review.

Compare two borrowing scenarios

Changing debt service or income assumptions makes it easier to compare whether one option leaves more breathing room.

Translate annual cash flow into a lender-style metric

This can help make loan conversations easier to follow when DSCR comes up in term sheets or screening rules.

FAQ

Common questions

How is DSCR calculated?

The calculator divides annual net operating income or annual cash flow by annual debt service to estimate debt service coverage ratio.

What does a DSCR above 1.00 mean?

It means the income entered is higher than the annual debt service entered, so the estimate shows some level of coverage.

Is this enough for a lender decision?

No. It is a screening estimate only, because lender requirements and underwriting adjustments can vary.
