529 College Savings Calculator FAQ

- The tool factors in the concept of tax-free growth, but specific state tax deduction limits and eligibility vary; you should check your own state's rules to see how much of a benefit you can claim.
- How accurate are the projections compared to actual 529 plan performance?
- The projections are based on the annual return rate you enter and assume consistent monthly contributions; actual 529 returns will vary with market conditions, fees, and plan-specific investment options.
