Key Points
Having multiple children means potentially needing $200,000-$600,000 in total college savings. Decisions about whether to pool or separate savings, how to prioritize between ages, and how to handle unexpected needs require a systematic strategy.
College savings structures for multiple children
| Approach | Advantages | Disadvantages | Best For |
|---|---|---|---|
| Separate 529 per child | Equal tracking; child-specific | Less flexibility | Families committed to equal savings |
| Equal monthly per child | Fair and systematic | Younger children benefit from more compounding | Most families -- simplest |
| Proportional by age | Older child funded first | Younger child gets less growth time | Families focused on near-term |
| Primary 529, change beneficiary | Simple management | Requires tracking transitions | High-net-worth flexible funding |
If your older child receives a scholarship, roll the 529 to your younger child with no tax consequences. Unused 529 funds can also roll to the Roth IRA (SECURE 2.0) or future grandchildren. The flexibility of 529 accounts makes over-saving for one child far less risky than it once seemed.
What This Means for You
- Open a 529 for each child at birth -- even small contributions establish the account and start compounding
- Equal monthly contributions to each child’s 529 is the most common and straightforward approach
- Grandparent contributions can be directed to the child with the largest savings gap
- Review and rebalance contribution levels annually as each child’s timeline shortens
- The oldest child has the least time -- prioritize closing their gap first if behind
