Is Boldin or ProjectionLab better for beginners?

Boldin provides more guided structure and education around the plan. ProjectionLab gives more direct modeling freedom. Beginners who want prompts may prefer Boldin; people comfortable designing their own timeline may prefer ProjectionLab.

Which has the better free plan?

It depends on the task. ProjectionLab Basic explicitly includes Monte Carlo and historical backtesting. Boldin Basic emphasizes a personalized plan and what-if scenarios. Paid-only features should not be inferred from either free tier.

Which is better for Roth conversions?

Both list Roth-conversion capabilities on their paid tiers. Compare the tax scope, income thresholds, years modeled, and whether the output is analysis or an optimized recommendation before relying on a headline feature name.

Comparison

Boldin vs ProjectionLab

Boldin is a guided retirement-planning system with linked accounts, AI, and an advisory path. ProjectionLab is a flexible modeling environment with historical backtesting and international planning.

By Steven, Founder · Updated September 3, 2026

Short answer

Choose Boldin when guided setup, linked accounts, state-and-federal projections, and optional human advice matter most.
Choose ProjectionLab when flexible event modeling, historical backtesting, international planning, and direct control matter most.
Both have free plans; compare the paid tier that contains the decisions you actually need to model.

The short version

Boldin and ProjectionLab both build multi-year retirement projections, but they organize the work differently. Boldin leads a household through a broad planning system and places AI, classes, coaches, and a flat-fee advisory service around it. ProjectionLab gives the user a flexible canvas for timing income, spending, milestones, and scenarios.

Neither is universally better. The useful choice is the one whose data model matches your household and whose assumptions you can maintain and explain.

Pricing and the free starting point

Boldin Basic is free. PlannerPlus is $144 per year after a 14-day trial and adds more than 100 additional inputs, linked accounts, Roth conversion analysis, state and federal tax projections, multiple scenarios, Monte Carlo analysis, and unlimited Boldin AI conversations.

ProjectionLab Basic is free and lists forecasting, financial planning, Monte Carlo simulations, historical backtesting, and flexible modeling. Premium is $129 per year and adds cash-flow projections, tax optimization, withdrawal strategies, what-if scenarios, Roth conversions, ACA subsidies, international planning, and advanced analytics. Its Pro tier is $549 per year for advisors and coaches.

Guidance versus modeling freedom

Boldin is the more guided choice. Its paid plan lists 250-plus inputs, linked accounts through three aggregators, personalized suggestions, classes, and AI that can answer questions against the plan. A separate $3,200 flat-fee advisor checkup is available for people who want a professional to turn the model into an action plan.

ProjectionLab is the more open-ended modeling choice. Its public product pages emphasize flexible milestones, scenarios, historical backtesting, international planning, and direct manipulation of a financial timeline. That freedom suits people who already know which events and assumptions they want to encode.

Simulation and tax questions

Both paid products offer Monte Carlo analysis and tax-aware retirement features. ProjectionLab also lists historical backtesting on its free tier, making it easier to inspect how a plan behaves in observed market sequences. Boldin's paid tier explicitly lists state and federal tax projections and a Roth conversion explorer.

Do not compare success percentages until the household inputs, tax scope, return method, planning age, and success definition are aligned. Different modeling choices can produce different percentages from the same balances and spending.

Where Meridary fits

Meridary is a narrower third option: manual entry, two-earner U.S. wages, one Social Security benefit, federal tax plus a flat state rate, RMDs, Roth conversions, IRMAA, ACA premiums, and explicit model limits. It costs $149–$199 for a founding lifetime license or $12 per month, with no free tier or trial and a 30-day money-back guarantee.

That is a fit when a bounded guided model and a lifetime purchase matter more than linked accounts or a longer feature list. It is not the fit for international planning, detailed state tax rules, estate modeling, a human advisor, or a free ongoing plan.
