How to Calculate DSCR

DSCR is a simple ratio that compares how much net income a property produces to how much debt it carries.

DSCR Formula

DSCR = Annual NOI ÷ Annual Debt Service

Annual NOI = (Monthly Rent × (1 − Vacancy) − Monthly Expenses) × 12

Example: ($1,900 effective rent − $300 expenses) × 12 = $19,200 NOI
$19,200 ÷ ($1,200 × 12) = DSCR 1.33

A DSCR above 1.0 means the property generates more income than needed to service the debt. Lenders typically want to see at least 1.25 for comfortable approval.

DSCR Thresholds Explained

  • ≥ 1.25 — Likely approved by most DSCR lenders. The property earns 25% more than it costs to service the debt.
  • 1.0–1.25 — Marginal. Some lenders will approve with compensating factors (lower LTV, strong credit). Others will not.
  • < 1.0 — Likely denied. The property does not generate enough income to cover its debt. Improve rents, reduce expenses, or renegotiate loan terms.

Frequently Asked Questions

What is DSCR?
DSCR (Debt Service Coverage Ratio) measures whether a property generates enough income to cover its debt obligations. It is calculated by dividing the property's Net Operating Income (NOI) by its annual debt service (mortgage payments).
What DSCR do lenders require?
Most DSCR lenders require a minimum ratio of 1.0 to 1.25. A ratio of 1.25 is the most common threshold — it means the property earns 25% more income than needed to cover the mortgage. Some lenders accept 1.0 (break-even) for strong borrowers.
What is a DSCR loan?
A DSCR loan is a non-QM (non-qualified mortgage) loan where approval is based on the property's rental income rather than the borrower's personal income. This makes them popular with self-employed investors and those with complex income situations.
How is NOI calculated for DSCR purposes?
NOI (Net Operating Income) is the annual rental income minus all operating expenses — taxes, insurance, HOA fees, property management, and a vacancy allowance. Mortgage payments are excluded from NOI; they are the debt service that NOI is compared against.
Can I improve my DSCR?
Yes. You can improve DSCR by increasing rental income (value-add renovation, market-rate lease-up), reducing operating expenses, or negotiating a lower interest rate or longer loan term to reduce monthly debt service. A larger down payment also reduces the loan and therefore the monthly payment.
