The Power of Starting Early
- $200/month from birth at 7% → $84,000 at age 18. Total invested: $43,200. Growth: $40,800.
- $200/month starting at age 8 at 7% → $31,000 at age 18. You need $550/month to match the from-birth contribution.
- The cost of waiting 5 years on a $200/month plan: roughly $30,000 in lost growth. Time is the most powerful variable.
- Superfunding at birth — a grandparent contributing $90,000 at birth (5-year front-load) at 7% grows to $307,000 by age 18.
SECURE 2.0: The Roth IRA Rollover Rule (2024)
Starting in 2024, unused 529 funds can be rolled into a Roth IRA for the beneficiary — eliminating the main risk of overfunding. Rules: 529 account must be at least 15 years old, lifetime rollover limit is $35,000, subject to annual Roth IRA contribution limits ($7,000 in 2024), and rollover counts against the beneficiary's Roth contribution limit for the year. Contributions and earnings from the last 5 years are ineligible.
