529 Plan Calculator — Project Your Education Savings — USA 2026
Calculate how much your 529 college savings plan could grow. Estimate future college costs and how much to save monthly to fund your child education in.
The 529 plan is the most tax-advantaged way to save for education expenses in the United States. Contributions grow tax-free and withdrawals for qualified education expenses including tuition room and board books and computers are completely tax-free at the federal level. Many states also offer state income tax deductions for 529 contributions. With the average cost of a 4-year private university now exceeding $200000 starting a 529 early can make the difference between a debt-free graduation and six figures in student loans.
How much should I put in a 529 plan?
Aim to save at least one-third of projected college costs in a 529 plan covering the rest through financial aid scholarships and current income. For a child born today who will attend a public university in 18 years projected costs could be $180000-250000. Saving $300-500 per month from birth should cover a significant portion. The earlier you start the more compound growth helps.

Understanding Your Investment Returns
This calculator projects your returns using compound interest, where your earnings generate their own earnings over time. The power of compounding means that even small regular investments can grow into substantial wealth over long periods. For example, investing just Rs 5,000 per month at 12% expected returns for 25 years can grow to over Rs 1 crore — of which only Rs 15 lakh is your own money and Rs 85 lakh is compounding returns. The key factors that determine your final corpus are: the amount invested, the rate of return, the duration of investment, and the frequency of compounding.
Important Considerations
Past returns do not guarantee future performance, especially for market-linked instruments like mutual funds and equities. The returns shown are estimates based on the rate you enter. Equity investments carry market risk but have historically delivered 12-15% CAGR over 15+ year periods in India. Fixed income options like PPF (7.1%) and FD (6-7.5%) offer lower but more predictable returns. Diversifying across asset classes — equity, debt, gold, and real estate — reduces overall portfolio risk while optimizing returns for your risk tolerance.

How much should I put in a 529 plan?

The earlier you start the more compound growth helps.
What happens to unused 529 money?
Unused 529 funds can be transferred to another family member for their education including siblings cousins or even parents. Since 2024 you can also roll over up to $35000 of unused 529 funds into a Roth IRA for the beneficiary subject to annual Roth contribution limits and a 15 year account age requirement. Non-qualified withdrawals incur income tax plus a 10% penalty on earnings only.
Can I use 529 for K-12 or trade schools?
Yes since 2018 you can use up to $10000 per year from a 529 plan for K-12 tuition at private elementary and high schools. 529 funds also cover accredited trade schools vocational programs apprenticeships and even student loan repayments up to $10000 lifetime. This expanded eligibility makes 529 plans useful far beyond traditional four-year colleges.
What is compound interest and why does it matter?
Compound interest means you earn interest on your interest, not just your principal. Over long periods, this creates exponential growth — even small regular investments can grow into substantial wealth over 15-25 years.
Should I invest regularly or as a lump sum?
Regular investing (dollar-cost averaging) smooths out market volatility by buying at various price points. Lump sum investing works better if markets are undervalued. For most people, regular monthly investing is simpler and more disciplined.
How much should I invest monthly to reach my goal?
The amount depends on your target, timeline, and expected returns. Use this calculator to model different scenarios. The key factors are starting early, investing consistently, and reinvesting returns.
Are investment returns taxable?
Tax treatment varies by investment type and country. Capital gains, dividends, and interest income may be taxed differently. Consult a tax professional for advice specific to your situation and jurisdiction.
