Every fund reviewed on Dependable Income Investing is scored using our 13-factor Fund Report Card, organised into three weighted categories: Fund Attributes (20%), Risk (35%), and Return (45%). Each criterion is rated 1–5 by our analysts based on publicly available fund data.
We also calculate a Dependability Score — a weighted composite of six income-specific factors ranked by importance for retirement income investors: Yield Stability, Yield, Volatility, Capital History, Fund Risk, and Underlying Assets. This score answers the question income investors care about most: can I depend on this fund to pay me reliably?
