What is DSCR Calculator?
The DSCR Calculator helps investors and lenders measure a property's ability to cover debt obligations.
When to Use This Calculator
- Checking whether a rental property will qualify for a DSCR loan before you apply
- Comparing how much a rate increase would erode your debt-service coverage on a refinance
- Stress-testing a deal against a vacancy or rent-reduction scenario before you commit
- Sizing the maximum loan amount a property's income can support at a lender's minimum DSCR
- Comparing two competing properties purely on their ability to cover their own debt
- Explaining to a lender or partner why a deal is (or isn't) bankable on its income alone
Steps:
- Enter NOI and annual debt service.
- View DSCR and lender requirement status.
Formula
DSCR = NOI / Annual Debt Service
NOI = Net Operating Income (annual rental income − operating expenses)
Example: $50,000 NOI / $35,000 Debt Service = 1.43 DSCR
A DSCR > 1.25 typically meets lender requirements.

Related Concepts
- Net Operating Income (NOI): DSCR is calculated directly from a property's NOI, so an accurate NOI figure is the foundation of an accurate DSCR. Use our NOI calculator first to make sure your income and operating-expense numbers are complete before checking coverage.
- Cap Rate: Cap rate and DSCR answer different questions — cap rate shows the property's return on its price, while DSCR shows whether its income safely covers its debt. Strong investors check both with our cap rate calculator before committing to a deal.
- Cash-on-Cash Return: A property can pass a lender's DSCR minimum and still deliver a mediocre cash-on-cash return, or vice versa — DSCR is a lender's risk metric, cash-on-cash is an investor's profitability metric. Compare both with our cash-on-cash return calculator.
- Refinancing to Improve DSCR: Refinancing to a lower rate or longer amortization directly reduces your annual debt payment, which raises DSCR without touching the property's income at all. Model potential refinance scenarios with our refinance calculator.
- Rental Property Cash Flow: DSCR is one output of a full rental analysis alongside monthly cash flow, cap rate, and cash-on-cash return. Run the complete picture through our rental property calculator to see how debt coverage fits alongside the property's other numbers.
Example
With $50K NOI and $35K debt service, DSCR is 1.43x, which meets most lender requirements.
Interpreting Your Results
DSCR compares a property's net operating income to its annual mortgage payment — a DSCR of 1.25 means the property generates 25% more income than it needs to cover its debt, which is the minimum most commercial and DSCR-loan lenders require. A DSCR below 1.0 means the property's income doesn't even cover its own mortgage, forcing you to subsidize it from other cash every month. A DSCR between 1.0 and 1.25 will often still get financed but at a higher rate or with a larger down payment, since lenders see it as thin coverage. Above 1.5 is considered strong and gives you room to absorb a vacancy, a rate reset, or a maintenance surprise without the property going cash-flow negative. Because DSCR is calculated on NOI (income minus operating expenses, before the mortgage), remember that it moves independently of your down payment size — refinancing to a lower rate or raising rent both improve DSCR directly, while a larger down payment lowers the mortgage payment and improves it indirectly.
