A Coverdell Education Savings Account is the only college savings vehicle that also pays for K-12 expenses — elementary and secondary school tuition, uniforms, tutoring, and even a computer. The trade-off is the smallest contribution limit in the tax code: $2,000 per beneficiary per year, phased out for higher incomes, with every dollar required to be spent by the time the beneficiary turns 30 or it is taxed as income plus a 10% penalty.
| Scenario | Years | Return | Balance at Age 30 | Tax-Free Growth | Tax-Free Withdrawal |
|---|---|---|---|---|---|
| Full $2,000/yr, 18 years, 7% return | 18 yrs | 7% | $72,758 | $36,758 | $70,000 |
| Late start at age 10, 8 years, 7% | 8 yrs | 7% | $21,956 | $5,956 | $21,956 |
| Full $2,000/yr, 18 years, 5% return | 18 yrs | 5% | $59,078 | $23,078 | $50,000 |
The $2,000 cap is per-beneficiary, not per-contributor: two parents, four grandparents and the child can each contribute, but the total for one child cannot exceed $2,000 in a year. Returns are historical assumptions, not guarantees.
Both grow tax-free and both allow tax-free withdrawals for qualified education costs. The differences come down to five trade-offs:
| Feature | Coverdell ESA | 529 Plan |
|---|---|---|
| Annual contribution limit | $2,000 per beneficiary | No annual limit; lifetime cap $235k–$550k+ |
| Income phase-out | Yes — $95k–$110k single, $190k–$220k joint | None, or deducted from state tax |
| K-12 qualified expenses | Yes — up to age 30 | Limited: $10,000/yr tuition for K-12 |
| Age deadline | Must be used by age 30 | None |
| Self-directed investing | Brokerage-style, any asset | Menu of plan-investment options |
For a single filer, the allowed contribution slides from the full $2,000 at $95,000 of MAGI to zero at $110,000. Married filing jointly: full at $190,000, zero at $220,000. The tax years shown are the same limits set when the account was created in 1997 — they have never been indexed to inflation, which is why a "small" account today is far smaller in real terms than it was at creation. If your MAGI lands inside the phase-out band, the calculator scales your contribution proportionally.
Contributions must stop when the beneficiary turns 18 (except for special-needs beneficiaries, who may contribute past 18 and have no age-30 deadline). The entire balance must be distributed by age 30. If it is not, the earnings are taxed as ordinary income plus a 10% additional tax — the same penalty as a non-qualified distribution. The one escape hatch: the account can be rolled to a family member under age 30, which restarts their clock and avoids the forced distribution entirely.
⚠️ Important: This calculator projects a Coverdell ESA balance from assumed returns, which are not guaranteed. The $2,000 limit and the income phase-out figures are statutory and unchanged since 1997. It does not model state tax treatment or the special-needs beneficiary exception to the age-30 rule.
