Frequently asked questions
- What return should I assume for a 529?
- It depends on the plan's investments. Many savers use 5–7% for a diversified, equity-tilted portfolio and lower as the child nears college (age-based glide paths). Enter a net-of-fee number for realism.
- Are 529 earnings taxed?
- Earnings grow tax-deferred and qualified education withdrawals are generally federal-tax-free; many states add deductions or credits. This calculator shows pre-tax-benefit growth only.
- Does this include plan fees?
- No. Subtract the plan's expense ratio from your return before entering it if you want a fee-adjusted projection.
