DSCR Calculator
Calculate Debt Service Coverage Ratio (DSCR) from net operating income and total debt service. Assess loan eligibility and financial health.
Formula
DSCR = Net Operating Income / Annual Debt Service
Where NOI = gross income minus operating expenses (excluding debt service), and Annual Debt Service = total principal and interest payments per year. A DSCR above 1.0 indicates sufficient income to cover debt obligations.
Worked Examples
Example 1: Apartment Complex DSCR Analysis
Problem: A 20-unit apartment complex generates $120,000 NOI. The loan is $1,000,000 at 6.5% for 25 years. Calculate DSCR.
Solution: Monthly payment = $1,000,000 x [0.005417 x (1.005417)^300] / [(1.005417)^300 - 1]\nMonthly payment = $6,753\nAnnual debt service = $6,753 x 12 = $81,038\nDSCR = $120,000 / $81,038 = 1.48
Result: DSCR: 1.48 - Good to Excellent. Property generates 48% more income than needed.
Example 2: Maximum Loan Amount Calculation
Problem: A retail property generates $200,000 NOI. The lender requires DSCR of 1.25. Interest rate is 7%, 20-year term. What is the max loan?
Solution: Maximum annual debt service = $200,000 / 1.25 = $160,000\nMax monthly payment = $160,000 / 12 = $13,333\nUsing loan payment formula in reverse:\nMax loan = $13,333 x [(1.005833)^240 - 1] / [0.005833 x (1.005833)^240]\nMax loan = approximately $1,718,000
Result: Maximum loan: ~$1,718,000 to maintain 1.25 DSCR at 7% over 20 years.
Frequently Asked Questions
What is the Debt Service Coverage Ratio (DSCR) and why does it matter?
The Debt Service Coverage Ratio measures a property's ability to generate enough income to cover its debt obligations. It is calculated by dividing the Net Operating Income (NOI) by the total annual debt service (principal plus interest payments). A DSCR of 1.0 means the property generates just enough income to cover debt payments with nothing left over. Lenders typically require a minimum DSCR of 1.20 to 1.35 for commercial real estate loans, providing a buffer against income fluctuations. A higher DSCR indicates stronger cash flow and lower default risk. For example, a DSCR of 1.50 means the property earns 50% more than needed to service its debt, offering substantial safety margin for investors and lenders alike.
How can investors improve their DSCR to qualify for financing?
Several strategies can improve DSCR for loan qualification. Increasing NOI is the most direct approach: raising rents to market rates, reducing vacancy through better marketing, adding revenue streams like laundry or parking fees, or reducing operating expenses through energy efficiency upgrades and competitive bidding on service contracts. On the debt side, borrowers can improve DSCR by making a larger down payment (reducing loan amount and thus debt service), negotiating a lower interest rate, extending the amortization period to reduce monthly payments, or using interest-only periods at the start of the loan. Some borrowers also restructure by combining a conventional first mortgage with mezzanine debt or preferred equity to achieve the required senior DSCR.
Is my data stored or sent to a server?
No. All calculations run entirely in your browser using JavaScript. No data you enter is ever transmitted to any server or stored anywhere. Your inputs remain completely private.
How do I interpret the result?
Results are displayed with a label and unit to help you understand the output. Many calculators include a short explanation or classification below the result (for example, a BMI category or risk level). Refer to the worked examples section on this page for real-world context.
How do I get the most accurate result?
Enter values as precisely as possible using the correct units for each field. Check that you have selected the right unit (e.g. kilograms vs pounds, meters vs feet) before calculating. Rounding inputs early can reduce output precision.
