$108,000.00 ÷ $100,000.00

1.08x

Illustration only. This scenario does not determine eligibility, indicate lender approval, or set a universal qualifying threshold.

04 · The calculation

DSCR = annual NOI ÷ annual debt service

Annual NOI
$120,000.00
Annual debt service
$100,000.00

$120,000.00 ÷ $100,000.00 = 1.20x

Both amounts cover the same 12-month period.

05 · Interpretation

How to read this estimate

DSCR compares NOI with annual debt service. Lenders may assess current or stabilized property income and may use an amortizing payment even when interest-only is available. Calculation methods and thresholds vary by lender and program. This is a preparation estimate only; it does not determine eligibility or predict approval.
