Common Mistakes to Avoid
⚠️
Underestimating college inflation
College costs grow 4–6%/yr — faster than general inflation. Use 5% minimum for projections.
⚠️
Waiting too long
Starting at birth vs age 10 can nearly double your final balance due to extra compounding years.
⚠️
Taxable account vs 529
529 growth is federal tax-free for qualified education expenses. Taxable accounts erode returns annually.
