DSCR
Debt Service Coverage Ratio
Canadian mortgage term definition with formula, examples, and limits used by mortgage brokers.
Definition
Used for rental/investment properties. Measures whether rental income covers the mortgage payment. A DSCR ≥ 1.0 means the property is cash-flow positive.
Formula
DSCR = Net Rental Income ÷ Annual Mortgage Payment (P&I)
Standard Limit
DSCR ≥ 1.0 preferred; some lenders require ≥ 1.1 or ≥ 1.2
Example
Rental income $3,600/month ($43,200/yr), mortgage payment $3,000/month ($36,000/yr): DSCR = 43,200 / 36,000 = 1.2.
