Does ProjectionLab currently list a lifetime plan?

Its official pricing page accessed September 2, 2026 lists free Basic, $129-per-year Premium, and Pro pricing; it does not list a consumer lifetime purchase. Meridary currently offers a founding lifetime license.

Is Meridary as configurable as ProjectionLab?

No. ProjectionLab lists a broader set of modeling, comparison, tax, estate, and international features. Meridary intentionally limits its household and planning scope.

Comparison

Meridary vs ProjectionLab

ProjectionLab emphasizes flexible, detailed model building. Meridary emphasizes a guided U.S. retirement path with an explicitly narrower scope.

Short answer

ProjectionLab's current pricing lists a free Basic tier and Premium at $129 per year.
Meridary offers a founding lifetime license as well as a monthly option.
ProjectionLab exposes more modeling and optimization controls; Meridary keeps the supported path narrower.

The central difference

ProjectionLab's current product pages describe flexible financial modeling, Monte Carlo and historical backtesting, tax estimates, cash-flow projections, withdrawal strategies, Roth conversions, ACA subsidies, and coordinated optimization. Premium is listed at $129 per year; Basic is free.

Meridary focuses on one guided U.S. retirement model rather than an open-ended planning canvas. Its founding lifetime license is $149–$199, with a $12-per-month option for the same planner access.

Choose ProjectionLab for modeling flexibility

ProjectionLab is the clearer choice when you want to construct complex timelines, compare many scenarios, use international presets, explore coordinated tax strategies, or adjust a larger set of planning variables.

Choose Meridary for a narrower guided workflow

Meridary is the clearer choice when its bounded U.S. household scope fits and you would rather work through a curated set of inputs. Its source and validation pages state what is calculated, what is tested, and what remains outside the model.

Compare the actual plan you need

ProjectionLab's extra flexibility is useful only if you need and maintain it. Meridary's tighter boundaries are useful only if they still represent your household. Test that fit before comparing charts or headline prices.
