Debt-Service Coverage Ratio — DSCR Formula & Calculation
Financial Ratios

Debt-Service Coverage Ratio

Understanding DSCR helps you assess whether rental income can cover loan payments and qualify for real estate financing.

Debt-Service Coverage Ratio (DSCR) measures your ability to cover debt payments with operating income. Formula: DSCR = Net Operating Income ÷ Total Debt Service. For rental properties, it's net rental income divided by annual loan payments. A ratio of 1.0 means income exactly covers payments; 1.25+ is considered healthy. Most lenders require 1.20-1.25 minimum for real estate loans. Higher ratios mean lower risk and better loan terms.

DSCR Formula

DSCR = Net Operating Income ÷ Total Debt Service

For rental properties, this becomes:

DSCR = Net Rental Income ÷ Annual Debt Payments

DSCR Calculation Example

Rental Property: Single-family rental

Annual Gross Rent: $3,000/month × 12 = $36,000

Annual Expenses:

  • • Property taxes: $3,600
  • • Insurance: $1,200
  • • Maintenance (8%): $2,880
  • • Vacancy (5%): $1,800
  • Total Expenses: $9,480

Net Rental Income: $36,000 - $9,480 = $26,520

Annual Debt Payments: $20,000

DSCR = $26,520 ÷ $20,000 = 1.33

What DSCR Means

1.50+ (Excellent)

Strong cash flow. You'll get the best rates and terms. Property generates significant income beyond debt payments.

1.25-1.50 (Good)

Meets most lender requirements. Good cash flow with comfortable margin. Competitive rates available.

1.20-1.25 (Minimum)

Meets minimum requirements but tight. May need higher down payment or pay slightly higher rates.

Below 1.20 (Not Qualified)

Rental income doesn't cover payments. Loan will be denied. Need to increase rent, reduce purchase price, or increase down payment.

How Lenders Use DSCR

Lenders use DSCR to assess loan risk and determine terms:

  • Approval Decision: Most lenders require 1.20-1.25 minimum. Below this threshold, loans are typically denied.
  • Interest Rates: Higher DSCR ratios get better rates. A 1.50+ DSCR may qualify for rates 1-2% lower than a 1.25 DSCR.
  • Loan-to-Value (LTV): Higher DSCR may allow higher LTV (up to 80% vs 70% for lower DSCR).
  • Loan Amount: Higher DSCR may qualify for larger loan amounts relative to property value.

How to Improve Your DSCR

1. Increase Rental Income

Raise rents (if market allows), reduce vacancy, or add income streams (parking, storage, etc.). Higher income improves DSCR directly.

2. Reduce Operating Expenses

Negotiate lower property taxes, shop for better insurance, or reduce maintenance costs. Lower expenses increase net rental income.

3. Increase Down Payment

Larger down payment means smaller loan amount and lower monthly payments, improving DSCR.

4. Negotiate Better Loan Terms

Longer terms or lower interest rates reduce monthly payments, improving DSCR. Learn about real estate lending options.

Frequently Asked Questions

What's a good DSCR ratio for rental property?

Most lenders require 1.20-1.25 minimum. A ratio of 1.50+ is considered excellent and gets you the best rates and terms. Below 1.20 means rental income doesn't cover payments, so loans are typically denied.

How is DSCR different from debt-to-income ratio?

DSCR measures property income vs property debt payments. Debt-to-income (DTI) measures personal income vs personal debt payments. DSCR is used for investment properties; DTI is used for owner-occupied properties.

Can I get a loan with DSCR below 1.0?

Very unlikely. A DSCR below 1.0 means rental income doesn't cover loan payments, which is too risky for lenders. You'll need to improve the property's income or reduce the loan amount (larger down payment).

Do I need existing rental income to calculate DSCR?

Existing rental income helps, but lenders can use market rent estimates for new purchases. They'll verify rent comparables in the area to ensure estimates are realistic.
