529 College Savings Calculator
Adjust the inputs below. Results update as you type.
How it works
A 529 projection links contribution habits to a future education funding target. Enter what you can save regularly, the years until tuition starts, and a conservative expected return. Compare the projected balance with an estimated college cost path rather than assuming markets will close every gap. State tax benefits, investment menus, and qualified-expense rules differ by plan. Use this page to set a savings rate, then confirm plan documents and beneficiary rules before large transfers.
Input guidance
- Use realistic rates from lender or provider quotes instead of headline averages.
- Model conservative, baseline, and optimistic scenarios before deciding.
- Include recurring real-world costs (fees, taxes, insurance, maintenance) where relevant.
More examples to test
- Conservative case: use a higher interest rate and lower growth assumptions to stress-test affordability.
- Optimistic case: use a lower rate with stable income assumptions to compare upside potential.
How to interpret results
Treat this as a planning model, not a final approval tool. Compare at least two scenarios and focus on total-cost and cash-flow trade-offs.
When this can be inaccurate
Results can diverge due to fees, changing rates, tax rules, lender policies, and behavior changes that simplified models cannot fully capture.
