# Design College Savings Plan

Calculate the education funding target, choose the right account type, set monthly contributions, and invest appropriately for the timeline.

## Why This Is Best Practice

**Adopted by:** 529 plans are used by 30% of college-saving families (College Savings Plans Network). Vanguard, Fidelity, and every major brokerage offer 529 plans with age-based portfolios specifically designed for this goal. The CFP Board covers education planning as a distinct module.
**Impact:** College Board (2023) reports average 4-year cost at $110,000 (public in-state) to $240,000 (private). Starting a 529 at birth vs. age 10 reduces required monthly contributions by 60% for the same target — compound growth does the heavy lifting.
**Why best:** 529 plans offer triple tax efficiency: contributions grow tax-free, withdrawals for qualified expenses are tax-free, and 34 states offer deductions on contributions. The SECURE 2.0 Act (2022) allows rolling unused 529 balances to a Roth IRA — eliminating the "what if they don't go to college?" objection. No other account combines this tax profile for education.

## Steps

1. **Project the funding target** — Current 4-year cost × (1 + 0.05)^years_until_enrollment. Use 5% annual tuition inflation. For a child born today: public in-state $110k × 1.05^18 = $264k; private $240k × 1.05^18 = $577k. Choose a funding % target (full, 75%, 50%?) — loans, scholarships, and student earnings cover the rest.
2. **Calculate monthly contribution** — Use future value formula or online calculator. To fund $264k in 18 years at 7% average return: ~$580/month from birth. At age 5: ~$840/month. At age 10: ~$1,400/month.
3. **Choose the 529 plan** — Start with your state's plan if it offers a tax deduction (check savingforcollege.com). If no deduction or poor investment options, use Nevada (Vanguard), Utah (my529), or New York (NY 529 Direct) — lowest fees, best fund selection.
4. **Select an age-based portfolio** — Default to the plan's age-based option: starts aggressive (90% equity) and automatically glides to conservative (30% equity) as enrollment approaches. Only deviate if you have strong convictions and will actively manage.
5. **Coordinate with financial aid** — 529 accounts owned by a parent (not grandparent) have minimal FAFSA impact: only 5.64% of balance counted as parental asset vs. 20% for student-owned accounts. Grandparent-owned 529 distributions count as student income under old rules (but FAFSA simplification 2024 reduces this impact).
6. **Set up automatic contributions** — Link to paycheck or checking account; treat like a fixed expense. Increase annually by 3–5% or match raises.
7. **Know the SECURE 2.0 rollover rule** — Unused 529 funds (after 15-year holding period) can roll to Roth IRA for the beneficiary, up to $35,000 lifetime. Over-saving is now recoverable.

## Rules

- Open the 529 as early as possible — time in market matters more than contribution amount for long timelines.
- Do not fund 529 before maxing employer 401k match — the match is an instant 50–100% return that 529 tax benefits cannot beat.
- Change beneficiary to another family member if the named beneficiary doesn't use the funds — no penalty for beneficiary changes within the family.
- Keep 529 in the parent's name (not grandparent's) for better FAFSA treatment until post-FAFSA simplification rules are fully clear.

## Examples

**Child age 3, target: 50% of public in-state cost:**
Projected cost in 15 years: $110,000 × 1.05^15 = $229,000. Target: $114,500.
Monthly contribution at 7% return over 15 years: ~$375/month.
Plan: open state 529 (deduction available), age-based portfolio, $375/month auto-contribution.

## Common Mistakes

- **Waiting until high school** — Starting at 14 requires 3× the monthly savings vs. starting at birth for the same target.
- **Using a UGMA/UTMA instead of a 529** — UGMA/UTMA transfers ownership to the child at 18/21 and counts as student asset (20% on FAFSA); 529 stays under parental control with better tax treatment.
- **Choosing the wrong state's plan** — If your state has no income tax deduction, the lowest-cost national plans (Nevada/Utah/NY) beat your home state's plan.
