If you're looking at DSCR loans for your investment property, understanding how to calculate the Debt Service Coverage Ratio is essential. This guide breaks down the formula, walks through real examples, and explains what lenders are looking for.
The DSCR Formula
DSCR measures whether a property generates enough rental income to cover its debt obligations. The calculation is simple:
DSCR Formula
DSCR = Rental Income ÷ PITIA
PITIA = Principal + Interest + Taxes + Insurance + Association Dues
What's Included in PITIA?
PITIA represents your total monthly housing expense for the property:
- Principal & Interest: Your monthly mortgage payment
- Taxes: Annual property taxes divided by 12
- Insurance: Landlord/hazard insurance premium divided by 12
- Association Dues: HOA or condo fees (if applicable)
Example 1: Single-Family Rental
Let's calculate DSCR for a single-family rental in Ocean County, NJ:
Monthly Income
Market Rent: $2,800
Monthly PITIA
- P&I: $1,800
- Taxes: $450
- Insurance: $150
- Total: $2,400
DSCR Calculation: $2,800 ÷ $2,400
= 1.17
A DSCR of 1.17 means the property generates 17% more income than needed to cover the mortgage. This would qualify with most DSCR lenders.
Example 2: Multi-Family Property
Now let's look at a duplex in Newark — multiple units mean combined income:
Monthly Income
- Unit 1: $1,400
- Unit 2: $1,350
- Total: $2,750
Monthly PITIA
- P&I: $1,500
- Taxes: $400
- Insurance: $175
- Total: $2,075
DSCR Calculation: $2,750 ÷ $2,075
= 1.33
Multi-family properties often achieve higher DSCR ratios because combined rents exceed expenses proportionally. This duplex's 1.33 DSCR indicates strong cash flow.
What DSCR Ratio Do You Need?
Different lenders have different requirements, but here's a general guide:
| DSCR Ratio | Typical Requirements |
|---|---|
| 1.25+ | Standard rates and terms. Most lenders prefer this. |
| 1.0 – 1.24 | May need higher down payment or credit score. |
| Below 1.0 | Requires special programs. Higher rates and down payment. |
Tips for Improving Your DSCR
If your property's DSCR is borderline, here are ways to improve it:
- Larger down payment: Lower loan amount = lower P&I = better DSCR
- Buy down the rate: Points lower your interest rate and monthly payment
- Improve the property: Renovations can justify higher rent
- Shop insurance: Lower insurance premiums reduce PITIA

Common DSCR Questions
What is a good DSCR ratio?
A DSCR of 1.25 or higher is generally considered good, meaning the property generates 25% more income than needed to cover the mortgage. Most lenders require a minimum of 1.0 to 1.25. Higher ratios indicate stronger cash flow and may qualify you for better rates.
What does a DSCR of 1.0 mean?
A DSCR of 1.0 means the property breaks even — rental income exactly equals the mortgage payment (PITIA). The property covers its costs but generates no additional cash flow. Some lenders allow 1.0 DSCR, but you may need a larger down payment or higher credit score.
Can I get a DSCR loan with a ratio below 1.0?
Some lenders offer "no-ratio" or sub-1.0 DSCR programs, but they typically require larger down payments (30-35%) and higher interest rates. These programs exist for investors who are confident the property will appreciate or who plan value-add improvements.
