DSCR Loan Calculator: How to Calculate Your DSCR Ratio
- 15 hours ago
- 4 min read
Qualifying for a DSCR loan comes down to one number.
Your Debt Service Coverage Ratio — and whether your rental property generates enough income to cover its own payment.
Here's exactly how to calculate it.
DSCR = Gross Monthly Rental Income ÷ Monthly PITIA (principal, interest, taxes, insurance, and HOA). A DSCR of 1.0 means rental income exactly covers your loan payment. Most lenders require a minimum DSCR of 1.0, with 1.25 or higher qualifying for the best rates. No W-2s, tax returns, or personal income verification required.
What Is the DSCR Formula?
The formula is straightforward:
DSCR = Monthly Rental Income ÷ Monthly PITIA
PITIA includes:
Principal + Interest (your mortgage payment)
Taxes (monthly property tax)
Insurance (hazard insurance premium)
Association fees (HOA, if applicable)
Example:
Monthly rent: $2,400
PITIA: $1,800
DSCR: $2,400 ÷ $1,800 = 1.33 ✔
DSCR Ratio Benchmarks
How lenders interpret your ratio:
Below 1.0
Property loses money on paper. Most lenders won't approve. Some specialty programs exist with higher rates.
1.0
Standard minimum for most competitive DSCR programs.
1.01–1.24
More competitive loan terms.
1.25 and above
Strong DSCR. Qualifies for the best rates and terms.
How Lenders Calculate Rental Income
Lenders don't take your word for what a property rents for.
They verify income one of two ways:
Existing Lease
For occupied properties, lenders use the current signed lease.
Form 1007 Market Rent Appraisal
For vacant or new acquisitions, lenders order an appraisal that includes a market rent schedule.
This means you can qualify using projected rent — even without a tenant in place.
DSCR Calculator Example
A property you're buying in Florida:
Purchase price: $325,000
Down payment: $81,250 (25%)
Loan amount: $243,750
P&I payment (7.5%, 30yr): $1,706
Taxes: $270/mo
Insurance: $130/mo
HOA: $0
Total PITIA: $2,106
Market rent (appraisal): $2,400
DSCR: $2,400 ÷ $2,106 = 1.14 ✔
This qualifies on most standard DSCR programs.
DSCR for Short-Term Rentals
Short-term rental properties use a different income source.
Instead of a lease, lenders use AirDNA or Rabbu to project annual STR revenue. That number is divided by 12 to get monthly income.
The same DSCR formula applies — it's just a different income figure.

How to Improve Your DSCR Before Applying
Choose markets with strong rent-to-price ratios
Increase down payment to lower PITIA
Improve credit score for better rate and lower payment
Verify insurance and tax estimates are accurate
Avoid underestimating vacancy or overestimating rent
DSCR vs. Conventional Loan Qualification
DSCR loans qualify on:
✔ Property rental income
✔ No W-2s or tax returns
✔ No DTI calculation
✔ No property count limit
Conventional loans require:
✖ Full income documentation
✖ DTI calculation
✖ 10 property cap
✖ W-2s or tax returns
DSCR vs Conventional Loans for Beginners
Conventional loans:
• Require income verification
• Limit number of properties
• Use DTI calculations
DSCR loans:
• No income verification
• Focus on property
• Designed for investors
For many new investors, DSCR loans provide a more flexible entry point.
Key Takeaways
DSCR = Rent ÷ PITIA
1.0 minimum; 1.25+ preferred
Use appraisal rent for vacant properties
No personal income required
Bottom Line
Your DSCR ratio is the single most important number in non-QM rental lending.
Calculate it before you make an offer — and structure the deal to hit 1.25 or above for the best terms.
Frequently Asked Questions
What is a good DSCR ratio for a rental property loan?
A DSCR of 1.25 or higher is considered strong and qualifies for the best rates. Most lenders require a minimum of 1.0. Ratios between 1.0 and 1.24 typically qualify but may come with slightly higher rates or additional reserve requirements.
Can I qualify for a DSCR loan if my property breaks even?
Some lenders approve loans at a 1.0 DSCR, meaning your rental income exactly equals your debt payment. However, expect stricter terms or a higher rate. Certain programs also allow no-ratio DSCR for borrowers with strong credit and equity.
Does the DSCR calculation include all property expenses?
No. DSCR only measures gross rental income against PITIA — principal, interest, taxes, insurance, and HOA. It does not factor in property management, maintenance, or vacancy. Those affect your investment return but are not part of the lender's DSCR calculation.
Can I use projected rent to qualify for a DSCR loan?
Yes. For vacant properties or new acquisitions, lenders use an appraiser's market rent estimate (Form 1007) rather than requiring an existing lease. This allows investors to qualify on what the property should rent for — not what it currently rents for.
How is DSCR different from LTV?
DSCR measures cash flow — whether the property earns enough to cover its debt. LTV measures equity — what percentage of the property's value you're borrowing. Both matter: a strong DSCR supports qualification, while a low LTV supports the collateral position.
