Calculate Debt Service Coverage Ratio for any investment property. See instantly whether your deal meets lender minimums (typically 1.20–1.25x) and how it compares to DSCR loan requirements — used by private lenders, banks, and CMBS underwriters.
What Is DSCR?
Debt Service Coverage Ratio (DSCR) measures a property's ability to cover its loan payments from operating income. It's the first metric every lender looks at when underwriting a commercial or investment property loan. DSCR = NOI ÷ Annual Debt Service.
DSCR Loan Requirements in 2026
- 1.0x: Break-even. Property barely covers debt. Most lenders won't touch it.
- 1.20x: Minimum for most conventional and portfolio lenders.
- 1.25x: Standard SBA 504 and CMBS minimum.
- 1.35x+: Preferred by agency lenders (Fannie/Freddie multifamily).
- 1.50x+: Strong — gives borrower leverage to negotiate rate and terms.
How Lenders Use DSCR
Lenders use DSCR to size the loan. If your property's NOI doesn't support the DSCR minimum at the requested loan amount, the lender will reduce the loan until it does. This is called "debt-yield constrained" underwriting — common in today's environment when rates are elevated.

The Formula
DSCR = Net Operating Income (NOI) ÷ Annual Debt Service
NOI is effective gross income minus operating expenses — before debt and before capital expenditures. Annual debt service is the total of all loan payments (principal + interest) for the year.
Worked Example
A 12-unit multifamily property collects $180,000 in effective gross income and carries $72,000 in operating expenses, for an NOI of $108,000. The loan payment is $7,100/month, or $85,200/year.
DSCR = $108,000 ÷ $85,200 = 1.27
Most lenders would approve this deal on coverage: the property generates 27% more income than the debt requires.
What Counts as a Good DSCR in 2026?
Most commercial lenders require a minimum DSCR of 1.20–1.25x for multifamily and 1.25–1.35x for office, retail, and industrial. Agency multifamily debt (Fannie/Freddie) underwrites to a 1.25x minimum, with 1.35x+ preferred. Below 1.20x, expect a smaller loan, a higher rate, or a decline. Above 1.40x, the deal has meaningful cushion — attractive to lenders, and a signal the buyer may have room to leverage further.
Minimums Are the Gate, Not the Whole Market
DSCR loan programs for residential investors go as low as 1.0x, with no-ratio products available below that at higher rates. Bridge and value-add lenders often underwrite to a projected stabilized DSCR rather than the in-place number, and interest-only periods raise early-year coverage by removing principal from the payment. Published minimums describe institutional senior debt — deals below them close every day through different products and structures.
Why DSCR Decides Your Maximum Loan
Lenders size loans backwards from DSCR: they take your NOI, divide by required coverage, and that's the maximum debt service they'll allow — which converts to a maximum loan at prevailing rates. This is why a rate increase shrinks your loan even when the property hasn't changed: the same NOI supports less debt at a higher payment.
When a CCIM Analyst Uses DSCR
DSCR is one of the first three screens in professional underwriting, alongside cap rate and cash-on-cash return. It answers the lender's question (will this loan get repaid?) while cap rate answers the market's question (what is this income stream worth?) and cash-on-cash answers the investor's question (what does my equity earn?). A deal must clear all three to be worth pursuing — this calculator handles the first.
