Understanding DSCR for Real Estate Loans

DSCR loans have become one of the most popular financing tools for real estate investors because they qualify based on property income rather than personal income. Use this calculator alongside our cap rate calculator and rental property calculator for a complete picture.

DSCR Formula

DSCR = Annual NOI / Annual Debt Service

NOI = (Gross Rent × (1 − Vacancy %)) − Operating Expenses

DSCR Benchmarks

  • DSCR ≥ 1.25: Strong — qualifies for most DSCR loan programs.
  • DSCR 1.0–1.24: Marginal — some lenders may still approve with strong credit.
  • DSCR < 1.0: Negative cash flow — property income doesn't cover debt service.

Frequently Asked Questions

What is DSCR in real estate?

DSCR (Debt Service Coverage Ratio) measures a property's ability to cover its mortgage payments with rental income. DSCR = Net Operating Income / Annual Debt Service. A DSCR above 1.0 means the property generates more income than needed to cover debt payments.

What DSCR do lenders require?

Most DSCR lenders require a minimum DSCR of 1.20 to 1.25. A DSCR of 1.25 means the property generates 25% more income than needed to cover debt service. Some lenders will accept DSCR as low as 1.0 for strong borrowers.

How is DSCR calculated?

DSCR = Annual NOI / Annual Debt Service. Annual NOI = (Gross Rent × (1 − Vacancy Rate) − Operating Expenses) × 12. Annual Debt Service = Monthly Mortgage Payment × 12.

What is a DSCR loan?

A DSCR loan is an investment property loan where qualification is based on the property's cash flow rather than the borrower's personal income. This makes them ideal for self-employed investors or those with many rental properties.

What operating expense ratio should I use?

Most lenders use 25–35% of gross rents for operating expenses. Single-family rentals lean toward 25–30%; small multifamily 30–40%. Include property taxes, insurance, maintenance, management fees, and reserves.

What if my DSCR is below 1.0?

A DSCR below 1.0 means the property does not generate enough income to cover debt payments — it has negative cash flow. You would need to increase rent, reduce expenses, put down a larger down payment to lower the mortgage, or choose a different property.
