DSCR Calculator

A DSCR calculator helps real estate investors estimate whether a rental property generates enough income to cover its monthly mortgage obligation. DSCR stands for debt service coverage ratio and it is one of the key metrics lenders use when reviewing investment property loans.

This calculator is designed to help you quickly estimate the relationship between monthly rental income and monthly debt service. It can be useful when screening deals, comparing financing scenarios, or testing whether a property may qualify for DSCR financing.

If you are new to this topic, it may help to first review what DSCR is, how DSCR loans work, and how to calculate DSCR.

Many experienced investors also evaluate broader rental property risks when analyzing DSCR including operating risk, tenant stability, and insurance costs. Resources such as rental property risk management and rental property insurance cost can help provide additional context when reviewing deals.

How This DSCR Calculator Works

DSCR = Monthly rental income ÷ Monthly debt service

Monthly debt service typically includes:

  • Principal
  • Interest
  • Property taxes
  • Insurance
  • HOA dues if applicable
  • Other recurring property debt

How to Use the DSCR Calculator

  1. Enter monthly rental income.
  2. Enter monthly principal and interest payment.
  3. Add property taxes, insurance, and HOA dues.
  4. Include additional recurring debt if desired.
  5. Click Calculate DSCR to see the ratio.

What the Results Mean

  • 1.00 DSCR means rent exactly covers debt
  • Above 1.00 means income exceeds debt
  • Below 1.00 means income does not fully cover debt

For additional context review what is considered a good DSCR ratio.

Example DSCR Calculation

Example scenario:

  • $2,800 monthly rent
  • $1,850 principal and interest
  • $250 taxes
  • $100 insurance

$2,800 ÷ $2,200 = 1.27 DSCR

DSCR vs Cash Flow

DSCR measures whether rent covers debt obligations. Cash flow measures what remains after all expenses including maintenance, vacancy, management, and capital expenditures.

For deeper analysis review DSCR vs cash flow and what is good rental cash flow.

Investors should also review insurance exposure when evaluating profitability including rental property disaster insurance and flood insurance for rental properties.
