Educational platform Savingforcollege.com recently released its annual estimates for state-sponsored 529 plans.

This year's edition of the ratings used a new methodology based on four categories to determine the overall attractiveness of each plan on a five-point scale:

Performance: Historical investment returns of the plan.

Ease of use: Ease of opening, maintaining and using the plan.

Savings success: How well a plan's features help investors optimize their savings. Including both positive factors, such as online gifts or planning tools, and criticisms of savings such as fees.

Program delivery: How well the plan is positioned to perform reliably in the future based on criteria including program manager tenure, contract uncertainty, and plan quality tracking.

Focusing only on advisor-sold plans, top performers include offerings from BlackRock Advisors, T. Rowe Price, Hartford Funds and Putnam.

Here are the top 529 advisor-sold plans for 2024:
