What is a Good DSCR Ratio?

A DSCR of 1.25 is generally considered good. It means that the property generates 25% more income than it needs to cover its monthly debt payments. 

However, DSCR is calculated differently for traditional commercial properties and one- to four-unit residential rentals. 

For commercial properties, lenders typically divide net operating income (NOI) by debt payments. For residential rentals, DSCR lenders usually divide gross monthly rent by monthly PITIA.

The two formulas use different numbers. The commercial formula uses NOI, which subtracts operating expenses from rental income, and compares it with debt payments. The residential formula generally uses gross rent before operating expenses and compares it with PITIA. 

As a result, the same property can have a different DSCR under each formula. Always use the formula required by the lender and specific loan program.

What is a DSCR Ratio?

The debt service coverage ratio (DSCR) shows whether a property generates enough income to cover its monthly loan payments. Lenders use it to determine whether the property can support the proposed loan.

The DSCR ratio meaning changes slightly depending on the type of financing:

Context Debt Service Coverage Ratio Formula What the result shows
Commercial real estate NOI ÷ Total Debt Service Whether the income left after operating expenses can cover the principal and interest payments
Residential DSCR mortgage Gross Rental Income ÷ PITIA Whether the monthly rent can cover the principal, interest, taxes, insurance, and association dues

To calculate NOI, subtract operating expenses such as vacancy losses, management, maintenance, property taxes, insurance, and owner-paid utilities from rental income. Do not subtract loan principal or interest; those payments are counted separately as total debt service. Read Griffin Funding’s guide to net operating income for a fuller explanation.

Griffin Funding calculates residential DSCR using gross rent divided by PITIA. Depending on the property and program, qualifying rent may come from a current lease, an appraiser’s market-rent analysis, or documented short-term rental income.

How to Calculate a DSCR Ratio

For a residential DSCR mortgage, use monthly figures. The DSCR ratio formula is:

DSCR = Gross Monthly Rental Income ÷ Monthly PITIA

PITIA includes:

  • Principal and interest
  • Property taxes
  • Property insurance
  • Homeowner association dues, when applicable

Suppose an investor buys a $400,000 single-family rental, puts 25% down, and borrows $300,000 at an illustrative 7.0% fixed rate for 30 years. 

The property rents for $3,000 per month. For this hypothetical example, assume annual property taxes of $4,404, an annual insurance premium of $2,004, and association dues of $120 per month.

Residential DSCR input How the monthly amount is calculated Monthly amount
Gross rent Qualifying monthly rent from the lease or market-rent appraisal $3,000
Principal and Interest Monthly payment on a $300,000 loan at 7.0% for 30 years $1,996
Property Taxes $4,404 annual tax bill ÷ 12 months $367
Insurance $2,004 annual premium ÷ 12 months $167
Association dues Monthly association bill $120
Total PITIA $1,996 + $367 + $167 + $120 $2,650

These figures are hypothetical and are used only to demonstrate the DSCR calculation. Actual housing costs and rental income vary by property and location.

Residential DSCR = $3,000 ÷ $2,650 = 1.13

A 1.13 DSCR means the monthly rent is 13% higher than the monthly PITIA. It does not mean the property produces a 13% profit because this calculation does not subtract maintenance, management, utilities, repairs, or vacancy losses.

Now calculate the same property under the commercial DSCR convention:

Commercial DSCR = Net Operating Income ÷ Total Debt Service

Commercial DSCR is generally calculated with annual figures. The calculation starts with annual rental income and subtracts operating expenses to determine net operating income. NOI is then divided by the property’s annual principal and interest payments.

Under the commercial convention, the same property has a hypothetical 5% vacancy, 8% management, 5% maintenance, with the same taxes, insurance, and association dues.

Commercial DSCR input How the annual amount is calculated Annual amount
Rental income $3,000 monthly rent × 12 months $36,000
Vacancy allowance 5% of $36,000 – $1,800
Management expense 8% of $36,000 – $2,880
Maintenance expense 5% of $36,000 – $1,800
Property taxes $4,404 hypothetical annual tax bill – $4,404
Insurance $2,004 hypothetical annual premium – $2,004
Association dues $120 per month × 12 months – $1,440
Net operating income $36,000 − $14,328 in operating expenses $21,672
Annual debt service $1,996 monthly principal and interest × 12 months $23,952
Commercial DSCR = $21,672 ÷ $23,952 = 0.90

The same property produces a 1.13 residential DSCR and a 0.90 commercial DSCR because the formulas treat income and expenses differently. Neither result is incorrect. 

The residential formula divides gross rent by PITIA, while the commercial formula subtracts operating expenses before dividing NOI by principal and interest payments.

Good DSCR Benchmarks by Band

Most lenders consider 1.25 a good DSCR ratio because it provides more room between qualifying income and the required debt payment. Griffin Funding has no minimum DSCR ratio, although the ratio can affect available programs, pricing, down payment or equity requirements, and reserves.

DSCR Ratio What it means at Griffin Funding
1.25 and above Best-pricing band
1.00 to 1.24 Excellent
0.75 to 0.99 Still qualifies with Griffin Funding
Below 0.75 Reserves-based or no-ratio options may be available

That flexibility is based on funded loans, not only program guidelines: in July 2026, Griffin Funding closed DSCR loans with ratios from 0.70 to 2.23, including two below 1.0. A lower ratio can narrow your choices, but it does not automatically end the application. Learn more about Griffin Funding’s sub-1.0 and no-ratio options.

What Different DSCR Levels Mean

Below 1.0

The qualifying rent is lower than PITIA. For example, a 0.90 DSCR means the rent equals 90% of the monthly payment. Many lenders will not approve the loan, but Griffin Funding may still consider it if the down payment and reserves support the file, or the property may qualify for a no-ratio program.

1.0

The gross rent exactly equals PITIA. The property covers the payment under the residential mortgage formula, but there is no room in that calculation for maintenance, management, utilities, repairs, or vacancy. A 1.0 DSCR is a break-even point for the loan calculation, not proof that the property is profitable.

1.25

The gross rent is 25% higher than PITIA. This is the common industry benchmark and places a Griffin Funding borrower in the best-pricing band, subject to the rest of the loan profile.

1.5 and Above

The gross rent is at least 50% higher than PITIA. That creates a stronger payment cushion and can support favorable terms. It still does not show the property’s complete return because the residential DSCR formula excludes most operating expenses.

Is a Higher DSCR Always Better?

A higher DSCR is generally better for loan pricing and gives the property more room to cover PITIA. It is not automatically better for the investor’s overall plan.

For example, a larger down payment raises DSCR by reducing principal and interest. But that equity is no longer available for renovations, reserves, or another purchase. A 1.50 ratio achieved with substantially more cash down may not serve the investor as well as a lower ratio with adequate reserves.

Griffin Funding currently places ratios of 1.25 and above in its best-pricing band. Exact pricing still depends on the loan program, credit score, leverage, property, prepayment structure, and market conditions. Compare the full terms rather than choosing a loan based on the ratio alone.

What Counts as a Bad DSCR Ratio?

There is no universal “bad” DSCR ratio. A ratio below 1.0 is a warning sign because gross rent does not cover monthly PITIA. The investor may need to contribute cash even before maintenance, vacancy, or other operating costs. 

A lower ratio can mean fewer loan programs, higher pricing, more equity, or stronger reserve requirements. With Griffin Funding, however, a low DSCR does not necessarily disqualify the property. 

In June 2026, a self-employed South Carolina investor used a property management letter to document the projected annual income from a short-term rental. High property taxes and flood-zone insurance brought the property’s DSCR below 1.0. 

Under Griffin Funding’s Tahoe DSCR pricing available at the time, the loan fell within the 0.75-to-1.0 band rather than being declined. The investor qualified for a DSCR loan using projected rental income instead of a full-documentation loan based on his personal income, and he closed the purchase in an LLC.

This example does not mean that a DSCR below 1.0 is financially strong. It shows that a sub-1.0 ratio may result in different pricing rather than an automatic denial.

A Griffin Funding loan officer can explain which programs and terms may be available based on your ratio and the rest of your loan profile. You can then review the property’s full rental income and operating expenses to decide whether it still fits your investment goals.

How to Improve Your DSCR

Improving a residential DSCR requires raising the qualifying rent, lowering PITIA, or using a program that does not rely on the ratio.

  • Increase the qualifying rent: Compare the lease with current market rent and ask which figure underwriting will use. Griffin Funding’s free rent estimator can provide an early estimate, but the lender’s documentation controls the final number.
  • Lower the loan payment: A larger down payment reduces the loan balance. Interest-only payments or a longer amortization period may also lower the monthly principal-and-interest amount. Some programs let you pay discount points at closing in exchange for a lower interest rate.
  • Review taxes and insurance: Verify the tax estimate for the rental property’s classification and location. Compare landlord-insurance quotes and correct any inaccurate coverage assumptions before relying on the projected PITIA.
  • Consider a no-ratio option: If the rent still does not support the proposed payment, Griffin Funding may be able to qualify the loan using reserves or a no-ratio program instead.

Compare the cost of each option with the potential benefit. A larger down payment or rate buydown can improve the DSCR, but the resulting terms may not justify the additional cash required upfront.

DSCR vs. Other Coverage Ratios

DSCR is one of several ratios used to evaluate debt:

  • Interest coverage ratio compares earnings with interest expense rather than total principal and interest payments.
  • Asset coverage ratio compares the value of available assets, after certain liabilities, with outstanding debt.
  • Cash coverage ratio considers whether cash or cash-based earnings are sufficient to cover debt or interest obligations, depending on the version used.

These ratios are not interchangeable. For a one- to four-unit residential DSCR mortgage, gross qualifying rent divided by PITIA is the relevant starting point. Investors deciding between loan types can also compare DSCR, conventional, and bank statement loans.

Frequently Asked Questions

Is a DSCR of 1.5 good?

Yes. A 1.5 residential DSCR is considered excellent. It means the property’s gross monthly rent is 50% higher than its monthly PITIA, providing a strong payment cushion. At Griffin Funding, this ratio falls within the best-pricing DSCR band, although final terms depend on the full loan profile. It does not mean the property earns a 50% profit because the calculation does not subtract operating expenses from gross rent.

What is a bad DSCR ratio?

There is no universal “bad” DSCR ratio, but a ratio below 1.0 is generally considered weak because the property’s gross rent does not fully cover its monthly PITIA. Depending on the lender and loan program, this may limit available options or require more equity or reserves. Griffin Funding has no minimum DSCR ratio, so a low ratio does not automatically disqualify the property for a DSCR loan.

What does a DSCR of 1.25 mean?

A 1.25 residential DSCR means the property’s gross monthly rent is 25% higher than its monthly PITIA. For example, a property with $2,500 in monthly rent and $2,000 in PITIA has a 1.25 DSCR. This ratio generally meets common lender thresholds and may provide access to more loan programs and better pricing than a lower ratio, although credit, equity, reserves, property type, and other loan details also affect the available terms. It does not mean the property earns a 25% profit because operating expenses are not deducted from gross rent.

Is a higher or lower DSCR better?

A higher DSCR is generally better for DSCR loan pricing because the property's rent provides more coverage for the payment. It is not the only consideration, however. An investor should also compare the cash required, reserves, operating expenses, and complete loan terms.

Does Griffin Funding use gross rent or NOI to calculate DSCR?

Griffin Funding calculates residential DSCR using gross qualifying rent divided by PITIA, not NOI divided by debt service. Because NOI subtracts operating expenses before the calculation, the NOI-based commercial ratio is usually lower for the same property.

Is there a minimum DSCR ratio to get a loan?

There is no universal minimum DSCR ratio. Many lenders require a ratio of 1.0 to 1.25, but Griffin Funding has no minimum requirement. In July 2026, Griffin Funding closed DSCR loans with ratios ranging from 0.70 to 2.23, including two loans below 1.0. Lower ratios may qualify when sufficient equity and reserves support the loan. Griffin Funding also offers no-ratio programs that do not use the property’s DSCR for qualification.

What DSCR do I need for a cash-out refinance?

There's no minimum DSCR for a Griffin Funding cash-out refinance, but leverage is ratio-dependent: reaching the maximum 80% LTV generally requires a DSCR of 1.0 or higher, and lower ratios may mean lower maximum leverage, more reserves, or a reserves-based or no-ratio structure. Use the DSCR calculator to estimate your ratio at the loan amount you want, then confirm current requirements for your property with a Griffin Funding loan specialist.
