Debt Service Coverage Ratio (DSCR) Calculator (Pro)

Measure a property’s ability to cover debt obligations with operating income.

Tool Overview

The Debt Service Coverage Ratio (DSCR) Calculator evaluates whether a property generates sufficient operating income to service its debt.

DSCR compares net operating income to annual debt service, providing a clear measure of income coverage and financial resilience. It is widely used by lenders, underwriters, and investors to assess risk, financing eligibility, and downside protection.

This tool helps investors move beyond simple cash flow analysis and evaluate whether income levels are adequate to support long-term debt obligations.

Analysis Depth

This tool provides income coverage analysis, not return forecasting.

It focuses exclusively on the relationship between operating income and debt service. The DSCR Calculator does not incorporate appreciation, equity growth, or exit assumptions.

Its purpose is to assess financial stability, lending risk, and the margin of safety embedded in a property’s income stream.

Understanding Income Coverage Margin

Income Coverage Margin shows how much of a property’s net operating income remains after paying debt service.

It answers a simple but important question:

“How much income cushion exists after meeting loan obligations?”

For example:

  • A higher margin indicates stronger financial resilience and more room to absorb income declines or expense increases.

  • A lower margin suggests tighter coverage and greater sensitivity to changes in income.

  • A negative margin indicates that operating income is insufficient to fully cover debt service.

While DSCR shows whether income covers debt, Income Coverage Margin shows by how much.

Used together, these metrics provide a clearer picture of income stability and downside risk.

Calculated Results & Performance Breakdown

After calculation, the tool reports:

  • Debt Service Coverage Ratio (DSCR)
    Net operating income divided by annual debt service.

  • Income Coverage Margin
    The percentage by which NOI exceeds debt service.

These outputs provide immediate insight into how much income cushion exists after meeting debt obligations.
