Understanding your investment property's financial performance is essential for smart real estate investing. One of the most critical metrics used by lenders—and savvy investors—is the Debt Service Coverage Ratio (DSCR). This figure helps determine whether a property generates enough income to cover its debt obligations.
Whether you're applying for a DSCR loan, refinancing a rental, or just analyzing potential deals, using a DSCR calculator will help you make informed decisions. In this article, we’ll explain what DSCR is, how it’s calculated, and how to use a DSCR calculator step-by-step.
What Is Debt Service Coverage Ratio (DSCR)?
DSCR is a financial metric that compares a property’s net operating income (NOI) to its annual debt service, which includes principal and interest payments on a loan.
DSCR Formula:
DSCR = Net Operating Income / Annual Debt Service
Example:
If your property produces $60,000 in net income and you pay $48,000 annually in loan payments:
DSCR = $60,000 ÷ $48,000 = 1.25
This means your property generates 25% more income than is needed to cover the mortgage.
