DSCR • Calculation

How to Calculate DSCR

Calculating a property’s debt-service coverage ratio is straightforward once you know what goes into it. Here is the formula.

The DSCR formula

The debt-service coverage ratio is calculated by dividing a property’s income by its debt obligations. In its most common form for rental property financing: DSCR = rental income ÷ debt payments, where debt payments typically include principal, interest, taxes, insurance, and any HOA or association dues (often abbreviated PITIA). The result is a ratio: if a property brings in $2,400 a month and its total debt payment is $2,000, the DSCR is 1.2.

What counts as income

For DSCR purposes, the income is generally the property’s rental income — either the actual rent (for a property already leased) or the market rent as determined by an appraisal or rent schedule (for a new purchase). Lenders have their own rules about which figure they use and how they document it. The point is that this is the property’s income, not your personal income, which is what makes DSCR loans distinctive.

What counts as debt

The debt side of the ratio is the property’s total housing payment: principal and interest on the mortgage, property taxes, insurance, and any HOA or condo dues. Getting an accurate picture of these costs matters, since underestimating them inflates the ratio. Our DSCR calculator can help you estimate the ratio for a property using figures you provide.

What ratio lenders want

Lenders generally look for a DSCR at or above a certain threshold, meaning the property’s income covers — or more than covers — its debt. A higher ratio indicates stronger cash flow and is viewed more favorably; a ratio below the threshold may still be financeable under some programs but can affect terms. The exact requirement varies by lender and program. As a Florida broker (NMLS #1967971), we can help you understand how a specific property’s ratio would be viewed.
