Free DSCR Calculator for Commercial Real Estate

Step 1: Calculate Net Operating Income (NOI). Start with the property's annual rental income (account for all lease revenue, parking, amenities, other income sources). Subtract operating expenses: property taxes, insurance, utilities, repairs and maintenance, management fees, reserves for capital expenditures. The result is NOI. Example: $500,000 rental income minus $350,000 operating expenses = $150,000 NOI.

Step 2: Calculate Annual Debt Service. If you have one loan, multiply the monthly payment by 12, or sum principal and interest across all payments for the year (they vary over time). If you have multiple loans, sum the annual payments on all loans. Example: A $600,000 loan at 6.5% over 25 years has an annual payment of approximately $48,000 per year × 2.5 loans = $120,000 total annual debt service.

Step 3: Divide NOI by Annual Debt Service. DSCR = $150,000 NOI / $120,000 Debt Service = 1.25. This property's DSCR is 1.25x, meaning it generates 25% more than the minimum required to cover debt payments.

Step 4: Interpret the Result and Stress-Test. With DSCR of 1.25, the property qualifies for agency loans (which require 1.25–1.35x). If NOI drops by 10%, DSCR falls to 1.125, which may violate loan covenants. Use the calculator to model "what-if" scenarios: What if occupancy drops to 90%? What if the largest tenant leaves? What if operating expenses rise 15%? This sensitivity analysis reveals which operational risks are most critical.

The CRELYTIC DSCR Calculator automates these steps and provides instant results. You can toggle between entering annual debt service directly (if you know it) or calculating it from loan parameters (loan amount, interest rate, term). The calculator also shows how your DSCR stacks up against different loan programs' requirements, so you can assess loan eligibility.

DSCR requirements vary significantly by loan program, lender, and market conditions. Here are typical minimums:

Agency Loans (Fannie Mae, Freddie Mac, HUD): Require DSCR of 1.25–1.35x. These are the most conservative lenders. They serve the secondary market (selling loans to institutional investors) and maintain strict underwriting standards. Fannie Mae typically requires 1.25x; Freddie Mac may require 1.35x for certain property types. These loans offer the lowest rates and best terms, but also the strictest qualification criteria.

CMBS (Conduit) Loans: Require DSCR of 1.30–1.50x, depending on subordination and the deal structure. CMBS deals are securitized and sold to bond investors, so underwriters are conservative. Larger deals and deals with strong sponsors may qualify at the lower end (1.30x). Smaller deals, newer properties, or weaker sponsors may require 1.40–1.50x DSCR.

Bank Loans: Require DSCR of 1.20–1.25x. Banks hold loans in portfolio (they don't securitize), so they have some flexibility. They also know their local markets. Smaller regional banks may accept 1.20x DSCR if they have confidence in the borrower and market. Larger money-center banks typically require 1.25x.

Bridge Loans: Require DSCR of 1.10–1.20x. Bridge lenders focus on exit strategy (how the borrower will repay at maturity) rather than current cash flow. They're willing to accept lower DSCR because the loan is typically short-term (18–36 months) and the goal is to stabilize the property or execute value-add improvements. As maturity approaches, DSCR expectations increase.

Life Company (Insurance Company) Loans: Require DSCR of 1.25–1.35x. Life companies operate like banks but with longer hold periods. They may be more flexible on DSCR for strong borrowers or trophy assets.

SBA/Non-Recourse Loans: Vary by program. Some SBA loans allow DSCR as low as 1.0; others require 1.25x. Non-recourse loans (where the lender has no claim on the borrower personally, only on the property) often require higher DSCR—1.35x or above—because the lender's only recourse is foreclosure on the property.

In tight credit markets (post-financial crisis, post-pandemic), all lenders raise DSCR requirements. In competitive markets with abundant capital, requirements may relax. The CRELYTIC DSCR Calculator compares your property's DSCR to standard requirements across all loan types, so you can immediately see which programs qualify and which don't.

If your property's DSCR is below your target (or below lender requirements), there are two levers: increase NOI or reduce debt service.

Increase NOI:

• Raise Rents. If market rents have grown or your in-place rents are below market, rent increases drive NOI up directly. Each $10,000 in annual rent increase flows through to NOI. However, aggressive rent increases can trigger tenant departures, so move carefully and stay market-aligned.
• Reduce Operating Expenses. Renegotiate insurance, property tax appeals, reduce utility costs through efficiency upgrades, or reduce management fees. Each $10,000 in expense reduction also increases NOI by $10,000. This is often the fastest path when rents are already at market.
• Improve Occupancy. Higher occupancy = more rental income. If your property is 85% occupied and market is 95%, closing that 10% gap could add 5–10% to NOI. Invest in leasing, improve tenant retention, or reposition the property to attract stronger tenants.
• Diversify Income. Add parking revenue, storage, vending machines, cell tower leases, or other ancillary income. These are often high-margin income sources.

Reduce Debt Service:

• Refinance at Lower Rates. If prevailing rates are lower than your current loan rate, refinancing reduces debt service immediately. A 100 basis point rate drop on a $600K loan could save $6,000/year in annual debt service.
• Extend the Loan Term. Moving from a 20-year to a 25-year amortization reduces annual payments. This is a quick DSCR fix, but increases total interest paid over the life of the loan.
• Pay Down Principal. If you have excess capital or strong cash flow, prepaying principal reduces your remaining loan balance and therefore debt service. This improves DSCR but ties up capital that could be redeployed elsewhere.
• Restructure Debt. If you have multiple loans, consider consolidating into a single loan with better terms. Or if a loan is near maturity, negotiate a new term to spread payments over a longer period.

The CRELYTIC DSCR Calculator lets you model the impact of these changes. What happens to DSCR if you raise rents by 5%? What if you reduce expenses by $20,000? What if you refinance at 6.0% instead of 6.5%? By running scenarios, you can identify which levers will have the biggest impact and prioritize your operational and financial strategy accordingly.

DSCR measures the income-side risk: does the property generate enough cash flow to pay debt? Loan-to-Value (LTV) measures the collateral-side risk: how much of the property's value does the loan consume?

DSCR (Income Risk): A property with DSCR of 1.10 is at high risk if cash flow drops. A job loss or tenant departure could make the loan unserviceable. DSCR addresses the question: "If rents drop, can the property still pay debt?"

LTV (Collateral Risk): A loan with 80% LTV means the lender has 20% equity cushion in the property. If the property value drops 20%, the loan is underwater. LTV addresses the question: "If property values drop, can the lender recover its investment through foreclosure?"

Lenders underwrite both. A property might have excellent DSCR of 1.40x (strong cash flow) but high LTV of 85% (risky collateral). Or conversely, a new development project might have low LTV of 60% (strong collateral cushion) but projected DSCR of 1.00x during lease-up (tight cash flow). Good underwriting balances both metrics.

For investors, understanding both metrics helps you evaluate risk. A property with strong DSCR but high LTV requires close attention to market trends—if property values soften, you could face a margin call or forced sale. A property with conservative LTV but weak DSCR requires operational focus—you need to stabilize the property and improve cash flow quickly to stay current on debt.

The CRELYTIC Debt Dashboard and DSCR Calculator work together. Use the dashboard to monitor property-level metrics including LTV and DSCR; use the calculator to stress-test scenarios and understand how operational changes impact cash flow and loan serviceability.
