Realism check
Maxifi uses an economic lifecycle model — a different approach from Monte Carlo. It optimises lifetime spending across scenarios rather than reporting a probability-of-success percentage. The outputs are accurate but require more interpretation than Boldin's probability gauge.
What Maxifi actually is
Maxifi Planner is a retirement and financial planning tool built on an economic lifecycle model rather than Monte Carlo simulation. This is a meaningful distinction: instead of running thousands of randomised scenarios and reporting a success probability, Maxifi optimises lifetime spending across a continuous model of future income, taxes, and assets.
The result: Maxifi is better at lifetime tax optimisation (specifically, multi-year Roth conversion ladders, optimal Social Security claiming, and multi-account withdrawal sequencing) and worse at giving you an intuitive “probability you don’t run out of money” gauge.
For most users, Boldin’s Monte Carlo approach is more interpretable. For high earners with complex situations, Maxifi’s economic model catches optimisation opportunities that simpler tools miss.
Who Maxifi is for
Segment 4 (HENRY — High Earner Not Rich Yet): users with AGI above $200K who need to model:
- Megabackdoor Roth ($46,500 above standard limit)
- In-plan Roth conversion timing
- NUA (Net Unrealised Appreciation) on company stock
- Deferred compensation vesting schedules
- Multi-account contribution stacking (401k + HSA + taxable + mega backdoor)
- IRMAA Medicare premium cliff management
For this audience, Maxifi’s ceiling is meaningfully higher than Boldin. For a conventional pre-retiree without these complexities, Boldin is the better fit.
Weaknesses
- Learning curve is real: Plan a serious onboarding session. This is not the tool to open on a Sunday afternoon and expect results in 30 minutes.
- No Monte Carlo probability gauge: The lifecycle model is academically correct, but “you’re on track” is harder to communicate to a non-technical spouse.
- Price: At $149-$309/yr, Maxifi costs more than Boldin ($120/yr) and ProjectionLab ($109/yr). The premium is justified for complex situations; not for standard pre-retirees.

Verdict
Maxifi is the right pick if you’re a high earner with complex equity comp and multi-account complexity, and you’re willing to invest time in the learning curve. For most pre-retirees without these complexities, start with Boldin.
