What is a 529 Plan?
The 529 Plan Calculator projects how much your 529 college savings account will be worth by the time your child starts college, based on your current balance, ongoing monthly contributions, and an assumed annual return. A 529 plan is a tax-advantaged US savings vehicle specifically designed for education costs — contributions grow tax-free, and withdrawals for qualified education expenses are also tax-free, making it one of the most efficient ways to save for college.
This calculator separates your Total Contributions (the money you actually put in) from your Total Tax-Free Growth (the investment returns on top), and also estimates your Annual State Tax Savings if your state offers a deduction for 529 contributions. For a fuller picture of how a 529 plan fits into broader savings and retirement planning, pair this tool with the Compound Interest Calculator and 401(k) Calculator.
How to use this 529 Plan calculator
- Enter your Current 529 Balance — your account's value today, or $0 if you haven't started yet.
- Enter your planned Monthly Contribution.
- Set Years Until College — your timeline until the funds will be needed.
- Adjust the Expected Annual Return based on your plan's investment option (more conservative for age-based portfolios near college start, more aggressive for younger beneficiaries).
- If your state offers a 529 tax deduction, enter your State Tax Deduction Rate to see your estimated annual tax savings.
- Review your Projected Balance at College, and the breakdown of contributions versus tax-free growth.
Formula & Methodology
The projected balance combines the future value of your current balance (compounded as a lump sum) with the future value of your monthly contributions (compounded as an ordinary annuity): FV(Lump Sum) = Current Balance × (1 + r)ⁿ FV(Contributions) = Monthly Contribution × [((1 + r)ⁿ − 1) ÷ r] Where r is the monthly rate (annual return ÷ 12 ÷ 100) and n is the total number of months until college. Example: $5,000 current balance, $250/month contribution, 10 years until college, 6% expected annual return. Monthly rate ≈ 0.5%, n = 120 months. The lump sum grows to roughly $9,090, and the monthly contributions grow to roughly $40,995. Total projected balance ≈ $50,085. Total contributions = $5,000 + ($250 × 120) = $35,000. Total tax-free growth ≈ $15,085.
Frequently Asked Questions
A 529 plan is a tax-advantaged US savings account specifically for education expenses, named after Section 529 of the Internal Revenue Code. Contributions grow tax-free, and withdrawals are also tax-free as long as they're used for qualified education expenses like tuition, room and board, books, and required fees.
Qualified expenses include tuition and fees, room and board (if enrolled at least half-time), required books and supplies, and computers or internet access required for enrollment. Since 2018, up to $10,000 per year can also be used for K-12 tuition, and 2019 legislation extended qualified use to registered apprenticeship programs and up to $10,000 in student loan repayment.
You can change the beneficiary to another family member without penalty, keep the funds for graduate school or future use, or as of 2024, roll over up to $35,000 (lifetime limit) into a Roth IRA for the beneficiary if the 529 account has been open at least 15 years. Withdrawing funds for non-qualified expenses triggers income tax plus a 10% penalty on the earnings portion only, not the full withdrawal.
No — about 30 states offer a state income tax deduction or credit for contributions to their own state's 529 plan, while a handful of states offer no state income tax at all, making the deduction irrelevant, and a few states allow a deduction for contributions to any state's plan. Check your specific state's rules, since this calculator's State Tax Deduction Rate input only estimates savings if your state actually offers one.
Yes — 529 plans are not restricted by state of residence, and you can use the funds at eligible schools anywhere in the country regardless of which state's plan you choose. Many savers compare plans across states for lower fees or stronger investment options, though doing so may mean forgoing your home state's tax deduction if one exists.
A common rule of thumb is to aim for roughly one-third of projected college costs from savings, one-third from current income and financial aid, and one-third from student loans, but the right number depends heavily on your timeline and target school cost. Use this calculator with different monthly contribution amounts to see how starting earlier or contributing more changes your projected balance by the time college begins.
No — 529 plans are typically invested in mutual funds or age-based portfolios that shift toward conservative investments as the beneficiary nears college age, and actual returns depend on market performance and the specific investment option you select. The expected return figure in this calculator is an assumption for projection purposes, not a guaranteed rate.
A 529 savings plan (what this calculator models) is an investment account that grows over time and can be used at any eligible institution. A prepaid tuition plan lets you lock in current tuition rates at specific in-state public colleges, which protects against tuition inflation but offers far less flexibility if the beneficiary attends a different school.
There's no federal annual contribution limit, but contributions above $19,000 per year per beneficiary (2025 figure, adjusted annually) count against your annual gift tax exclusion, and most states set an aggregate lifetime account limit (often $300,000-$550,000) once exceeded, no further contributions are allowed. Five-year 'superfunding' lets you contribute up to five years' worth of the annual exclusion in one lump sum without gift tax consequences.
Yes, but typically modestly — a 529 plan owned by a parent is counted as a parental asset on the FAFSA, which reduces aid eligibility by at most 5.64% of the account value, much less impactful than if the same funds were in the student's own name. Grandparent-owned 529 plans are no longer counted as an asset under the simplified FAFSA rules effective from the 2024-25 award year.
Compare your projected balance against your target school's estimated total cost (tuition, room, board, and fees for the expected number of years) to see the funding gap, then use the [Education Loan Calculator](/education-loan-calculator-india/) to model what borrowing the remainder might look like. Revisit this calculator periodically as your actual balance and contribution amount change to keep your projection current.
