Two questions
MaxiFi’s pricing page sells a lifetime financial plan, scenario comparison, retirement withdrawal and Social Security timing on Standard, and Living Standard Monte Carlo plus a Roth Conversion Optimizer on Premium. Killion’s public site sells named withdrawal rules, a seeded household Monte Carlo and read-only linking. Pick the question, then the tool.
Which one to choose
Choose Killion if
- You want Guyton-Klinger, VPW or Vanguard dynamic on a public calculator, then the same family in a linked household.
- You want the demo without buying a SKU to see Monte Carlo.
Choose MaxiFi if
- You want consumption smoothing and US tax/Social Security optimisation as the plan, not a withdrawal-rule laboratory.
