| Child Age Now | Years to College | In-State Public Target | Out-of-State Target | Private College Target |
|---|---|---|---|---|
| 0 (birth) | 18 years | $220/mo | $335/mo | $478/mo |
| 3 years old | 15 years | $316/mo | $481/mo | $687/mo |
| 5 years old | 13 years | $418/mo | $636/mo | $908/mo |
| 8 years old | 10 years | $634/mo | $965/mo | $1,379/mo |

As of 2024, unused 529 funds can be rolled into a Roth IRA for the beneficiary, up to $35,000 lifetime, with a 15-year account age requirement and other conditions. This change dramatically reduces the overfunding risk that made parents hesitate to contribute aggressively. Overfund the 529 slightly, and any excess becomes a Roth IRA head start for your child's retirement wealth.
529 Investment Return Assumptions by Age of Child
529 plans should use age-appropriate investment allocations because the money is needed at a specific known date. When the child is young (under 10), equity-heavy allocation is appropriate. As college approaches, shift toward more conservative allocation. Most 529 plans offer age-based options that do this automatically, similar to target-date retirement funds.
Age-appropriate 529 allocations and corresponding expected return rates for calculator input
| Child Age | Recommended Allocation | Expected Return Rate for Calculator |
|---|---|---|
| 0 to 10 years | 80% to 90% stocks | 7% nominal |
| 10 to 14 years | 60% to 70% stocks | 6% nominal |
| 14 to 16 years | 40% to 50% stocks | 5% nominal |
| 16 to 18 years | 20% to 30% stocks | 4.5% nominal |
| College starting | 10% stocks, cash | 4% nominal |
What If the 529 Falls Short?
- Scholarship applications: national merit, institutional, state-based scholarships can provide $5,000 to $50,000+
- In-state public vs. private reconsideration: $200,000 price difference may shift cost-benefit analysis at the decision point
- Work-study and part-time income: 10 to 15 hours per week can contribute $7,000 to $12,000 per year
- Student federal loans (subsidized): $3,500 to $5,500 per year at favorable rates do not require immediate repayment
- Parent PLUS loans: can bridge the gap but should be used conservatively due to higher interest rates
- Community college to four-year transfer: two years at community college followed by two years at university dramatically reduces total cost
