Use this free DSCR calculator to instantly find out whether a rental property generates enough income to qualify for a DSCR loan, no tax returns or personal income required. Enter the property’s rental income and estimated loan details to see your debt service coverage ratio and whether you meet lender thresholds.

DSCR Loan Calculator

Investing in rental properties is a great way to grow your wealth. With over 49.5 million rental housing units in the U.S., there’s tons of potential. Unfortunately, financing these investments can be challenging.

Real estate investors can choose many different types of home loans to finance their property purchases. A DSCR loan allows investors to avoid high rates, lengthy approval processes, and stringent lending criteria by qualifying based on cash flow instead of personal income.

This DSCR loan calculator can help you determine your debt service coverage ratio to ensure a high enough net operating income (NOI) to pay back the loan and ensure a return on investment. 

How Do You Calculate Your DSCR?

Your DSCR is the rental income your property generates divided by the property’s debt service.
Here’s how to calculate your debt service coverage ratio using the DSCR calculator above:

  • 1. Enter the Purchase Price

    Enter the total cost of your property.

  • 2. Enter the Interest Rate

    DSCR loan rates vary depending on a borrower’s financial profile and change throughout the year based on market conditions. You can find today’s current DSCR loan rates by doing a quick search online or visiting this page.

  • 3. Tell Us Your Loan Term in Years

    DSCR loans have terms of anywhere from 5 to 25 years with the length determined by the lender based on several financial factors, such as property type and projected cash flow.

  • 4. Enter Estimated Taxes

  • Input the estimated annual property taxes for the investment property. You can find this information by contacting the local tax assessor’s office, checking the county’s property tax records online, or reviewing recent tax bills for the property. The calculator defaults to 1.25% of the purchase price but you can enter a different value if you’d like.

  • 5. Enter HOA Fees

  • If applicable, input the estimated annual homeowners association dues for the investment property. You’ll own the property, so you’ll be responsible for these fees, but you can pass the cost onto tenants by including it in their rent.

  • 6. Enter Down Payment

  • Specify the amount you plan to put down on the property. Most lenders require a down payment of 20% to 40% of the property’s purchase price.

  • 7. Indicate the Total Loan Amount

    Loan amounts vary, with loan amounts of up to $20 million available. The lender will determine your total loan amount based on your DSCR. However, you can enter how much you need to borrow into our debt service coverage ratio calculator to help you find your DSCR.

  • 8. Review Loan Payment

    The DSCR calculator will determine your loan payment based on the other information you’ve given us. This metric will tell us your monthly debt obligations.

  • 9. Enter Insurance

    Input the estimated annual investment property insurance, which is also known as landlord insurance or rental insurance.

  • 10. Enter Gross Rental Income

  • Specify the total monthly rental income you expect to receive from the property before expenses. If you aren’t sure of the rent, you can use our free rental income estimator.

  • 11. Review Your DSCR

  • Once you’ve entered all the necessary information, our DSCR calculator will give you a decimal. This final number is your debt service coverage ratio that lenders use to determine your eligibility for a loan.

What Is a Debt Service Coverage Ratio (DSCR)?

Debt service coverage ratio (DSCR) is a metric used by lenders and investors to determine how well a rental property performs. For example, investors might calculate DSCR to determine if they’re making a profit, while lenders use it to determine a borrower’s ability to repay a loan. 

A DSCR above 1.0 indicates that a borrower is earning enough from their rental property to cover their monthly debt obligations, while a DSCR below 1.0 indicates that the borrower’s debt obligations are greater than the income being earned. 

Try out the above DSCR calculator for rental properties to get a snapshot of your investment property’s cash flow and see whether you’d be a good candidate for a DSCR loan.

What Is a DSCR Loan and Why Does It Matter?

A DSCR loan allows a real estate investor to qualify for financing based on a property’s cash flow rather than their personal income.

Real estate investors may have lower taxable income because they take deductions on their tax returns. With conventional commercial loans, this adjusted income might not be enough to qualify.

Instead, lenders can use the DSCR to determine eligibility based on cash flow, demonstrating if the property generates enough income for a borrower to repay the loan. The higher a DSCR, the more an investor earns, which is crucial for determining if they can turn a profit after paying their debts and provide them with a cushion for paying additional expenses.

In addition to DSCR purchase loans, Griffin Funding also offers DSCR home equity loans, which make it possible for investors to leverage the income generated by an investment property and tap into its equity. Investors can use funds from DSCR HELOANs and DSCR cash-out refinance loans for anything, including:

  • Maintenance and repairs 
  • Renovations and upgrades
  • Business expenses
  • Down payments for additional investment properties 

It’s important to note that DSCR loans are designed for real estate investors. Therefore, to purchase a primary residence, you’ll need to choose another type of funding, such as a conventional mortgage, non-QM loan, or a first-time home buyer grant.

What’s a Good DSCR?

A DSCR of 1 demonstrates that you have enough cash flow to repay the loan. However, most lenders require borrowers to have a higher DSCR because it allows for extra cash for expenses that won’t compromise their ability to repay the loan. The higher your DSCR, the stronger your position and the more likely you’ll be eligible for a loan. 

The minimum DSCR required for a loan varies by lender and condition of the economy. For example, lenders may accept lower ratios if more credit is available. That said, lenders usually require a DSCR of at least 1.25. 

Borrowers may still qualify for a loan with a lower DSCR as long as they can prove their ability to repay the loan in other ways, such as using personal income documentation. Griffin Funding allows you to qualify for a loan with a negative DSCR in certain cases. However, a higher DSCR can get you better terms and reduce your interest rate.

DSCR Formula

Our calculator uses this DSCR formula to calculate your ratio: DSCR= monthly NOI / debt payments.

If you don’t know your NOI, you can use the formula: NOI = (1 – expenses) (1 – vacancy) x Gross Income

In the DSCR calculation, gross income (GI) is the monthly rent your tenants pay you. Your expenses include operating costs, such as:

  • Paying employees
  • Maintenance and repairs
  • Cleaning 

Meanwhile, vacancy is the rate of how often you don’t have tenants. You can calculate the vacancy rate of a property using the following formula: Vacancy Rate = (Number of Days Vacant) / (Number of Days Available for Rent).

How Does DSCR Impact Your Loan Approval?

Your DSCR is one of the most significant metrics lenders use to determine loan eligibility and amounts, so you must ensure your ratio meets those requirements. However, since these loans are based on the NOI of a property, qualifying is easier than some other types of commercial loans. The application process is also much more streamlined since the requirements for DSCR loans are more flexible than other types of financing. 

The DSCR loan approval process works similarly to other real estate loans. For example, you’ll be required to pay closing costs, including origination, appraisal, and escrow fees, after loan approval. Additionally, if you’ve put down an earnest money deposit, we can provide a streamlined experience to help you get approval and funding quickly.

Can a Low DSCR Be Improved?

A few ways borrowers can improve a low DSCR before applying for a loan include:

  • Reducing operating costs
  • Increasing rental income
  • Refinancing the existing mortgage
  • Raising the property value

You still have options if you don’t qualify for a DSCR loan based on your ratio. Griffin Funding has more flexible requirements than other lenders, but if you fall below our requirements, you might qualify for another loan you can use for investing. We offer a wide range of investment property loans that are available to both new and experienced real estate investors.

How Does DSCR Differ from Other Financial Ratios?

DSCR is just one financial ratio lenders use to determine loan eligibility for investors. However, depending on the type of loan you get, there are a few other ratios to consider, including the following:

  • Interest coverage ratio: The interest coverage ratio compares your profits to the interest payment on debts instead of the total amount of debt itself. This ratio is similar to DSCR and can be used to help lenders determine if a company or borrower can pay back its debt. 
  • Asset coverage ratio: This ratio compares your ability to cover debt services by selling off assets. 
  • Cash coverage ratio: The cash coverage ratio determines if you can repay your debt using cash on hand.

Frequently Asked Questions

What is an example of calculating DSCR?

Remember, the formula for calculating DSCR is DSCR = gross monthly rental income / monthly debt payments. Let’s walk through an example of a DSCR calculation:

Let’s say you have an investment property that generates $75,000 in rental income per year, and your yearly debt service (including mortgage payments, taxes, and insurance) amounts to $55,000. To find your DSCR, you would perform the following calculation: 

DSCR = $75,000/$55,000 = 1.36

In this scenario, your DSCR is 1.36, which means the property’s income exceeds its debt obligations by 36%. Most lenders would consider a 1.25 to be a good DSCR when evaluating applications for DSCR loans, so you’d have a good chance of getting approved.

How does a DSCR loan work?

A DSCR loan is a type of financing for investment properties that focuses on the property’s rental income potential rather than the borrower’s personal income or creditworthiness. 

The DSCR is a key factor in determining loan approval and terms. Lenders use this number to assess whether the property’s income can cover its debt obligations and leave a little left over for the property owner to run their business. 

A higher DSCR means there’s less risk involved for lenders, which allows them to offer better terms.

What is the minimum down payment for a DSCR loan?

Borrowers can get a DSCR loan with a down payment as low as 20%. While this is the minimum down payment, making a higher down payment can help you secure a better rate and more favorable terms.

If you are not prepared to make a 20% down payment, we encourage you to explore other investment property loan options. For example, you can qualify for a bank statement loan with as little as 10% down.

Do I have other financing options if my DSCR is too low?

If your debt service coverage ratio doesn’t meet lenders’ requirements, you still have several options for financing an investment property. You can visit this page to find information about Griffin Funding’s investment property loans, such as: 

  • Conventional loans: Comparing a DSCR loan vs. a conventional loan, traditional mortgages are best suited for borrowers with strong credit and stable income. They often offer competitive interest rates and terms for investment properties. 
  • Bank statement loans: Ideal for self-employed investors, these loans use 12-24 months of bank statements as proof of income. They provide flexibility for those with complex income structures or tax write-offs. 
  • Asset-based loans: These loans consider the value of your assets rather than focusing on your wages. They can be a good option for investors with significant assets but lower reportable income. 
  • Private money loans: Hard money loans provide quick funding with more flexible terms. They’re often used for short-term financing or when traditional loans aren’t accessible. 
  • Home equity loans: If you have enough equity in your house or an investment property, you can borrow against it to finance another investment property.

What is the debt service coverage ratio (DSCR)?

The debt service coverage ratio measures a property’s annual gross rental income against its annual mortgage debt, including principal, interest, taxes, insurance, and HOA (if applicable). Lenders use DSCR to assess loan affordability based on cash flow. When calculating DSCR, lenders do not take into account expenses such as:

Management

Maintenance

Utilities

Vacancy rate

Repairs

Does Griffin Funding use gross rent or net operating income (NOI) to calculate DSCR?

The debt service coverage ratio measures a property’s gross rental income against its mortgage debt, including principal, interest, taxes, insurance, and HOA if applicable (PITIA). Lenders use DSCR to assess loan affordability based on the property’s cash flow rather than the borrower’s income.

Griffin Funding calculates DSCR on gross rent, not net operating income, so the following expenses do not count against your ratio:

  • Management
  • Maintenance
  • Utilities
  • Vacancy rate
  • Repairs

Some lenders calculate on NOI instead, which produces a lower ratio from the same property. The same deal can qualify here and be declined there purely on the math.

How does a DSCR loan work?

Here’s how a DSCR loan works:

Determine property income. The lender works with the borrower to determine the property’s gross monthly rental income, using either an existing lease or an appraiser’s comparable rent schedule. You can use our free rent estimator in the meantime to get an idea of what the property might rent for.

Account for monthly expenses. The lender tallies the monthly debt obligations on the property: principal, interest, taxes, insurance, and HOA fees (PITIA).

Calculate DSCR. A DSCR above 1.0 indicates the property earns enough to cover the mortgage, while a DSCR below 1.0 indicates it does not.

Loan approval based on DSCR. The lending decision is made on the property’s DSCR, the borrower’s broader financial profile, and the property details. No income documentation or tax returns are required.

Here’s what that looks like in practice. An investor purchases a single-family rental priced at $400,000, puts 25% down ($100,000), and finances the remaining $300,000 at an illustrative 7.0% rate:

Principal + interest$1,996
Property taxes$367
Insurance$167
HOA$120
Total PITIA$2,650
Market rent (comparable rent schedule)$3,000

DSCR = $3,000 ÷ $2,650 = 1.13

A 1.13 DSCR comfortably qualifies through our standard DSCR program. The investor closes without submitting tax returns, W2s, or pay stubs. The property’s rent qualifies the loan.

What happens if the property rents for less? At $2,500 a month against the same $2,650 PITIA, the DSCR drops to 0.94. Most lenders would decline at that ratio. Griffin Funding has no minimum ratio requirement, so we can still qualify the deal when reserves support it, or through our no‑ratio program, where the property’s cash flow isn’t used to qualify at all.

DSCR loans work especially well for active investors whose rental property deductions and depreciation reduce their reported income and make conventional investor financing difficult to qualify for.

Is DSCR calculated using actual rent or projected rent?

Both, depending on the property. A leased property is qualified on the lease or the appraiser's market rent analysis, and when both exist, underwriting generally uses the more conservative number. A vacant or newly purchased property is qualified on the appraiser's comparable rent schedule (Form 1007), and short-term rentals can use documented rental history or market data depending on the program. If your lease is significantly below market, talk to your loan officer before the appraisal is ordered, since the qualifying rent may not be the number you're collecting. Our free rent estimator gives you a working number before the formal analysis.

How is DSCR calculated?

The formula is: DSCR = Gross Rental Income ÷ PITIA. Gross rental income is the actual or market monthly rent the property generates. PITIA is the total monthly principal, interest, taxes, insurance, and HOA fees tied to the property. A result of 1.0 means the rent exactly covers the payment; above 1.0 the property cash-flows the debt, below 1.0 it doesn't. Run your own numbers in the calculator above.

How can I improve my DSCR?

If your ratio comes up short, the levers that actually move it are the inputs in the formula, rent and PITIA:

Increase the qualifying rent. Raise rents to market, or if your lease is below the appraiser's market rent analysis, ask your loan officer which number the file will use before the appraisal is ordered.

Lower the payment. A larger down payment is the fastest fix, since it directly shrinks the principal and interest the rent has to cover. An interest-only option or a longer amortization also lowers the monthly figure, and buying down the rate does the same.

Shop the tax and insurance line. Appealing an over-assessed property or rebidding the insurance lowers PITIA dollar for dollar, and unlike rent increases, it's entirely in your control before closing.

Or skip the ratio. If the deal still doesn't pencil, Griffin Funding has no minimum DSCR requirement, funds sub-1.0 ratios when reserves support them, and offers a no-ratio program that doesn't use cash flow to qualify at all.
