Introduction
A 529 plan is one of the best ways to save for college. It lets your money grow tax-free, which means more of your savings go toward education costs. But figuring out how much to save each month can be tricky. That's where our 529 Calculator comes in. This tool helps you see how much your savings can grow over time based on how much you put in, how long you save, and the return you expect to earn. Whether your child was just born or is already in middle school, this calculator gives you a clear picture of where you stand and what you need to do to reach your college savings goal.
How to Use Our 529 Calculator
Enter details about your child, college plans, and savings to see how much you need to save and whether you are on track to meet your college funding goal.
Child's Current Age: Use the slider or type in your child's age, from newborn (0) to 18. This tells the calculator how many years you have left to save before college starts.
Type of College: Pick the kind of school you are planning for — 2-year public, 4-year public in-state, 4-year public out-of-state, or 4-year private. Each option fills in an estimated annual cost based on current national averages.
Annual Cost of College: Review or change the estimated yearly cost of college in today's dollars. You can use the plus and minus buttons to adjust by $500, or type in your own number.
Number of Years of College: Choose how many years of college you want to pay for, from 1 to 6. A standard bachelor's degree is 4 years, and an associate's degree is 2 years.
Percentage of Cost to Cover: Use the slider or type in what portion of the total college cost you want your 529 savings to cover. For example, 50% means you plan to pay half from savings and the rest from scholarships, aid, or other sources.
Current 529 Savings Balance: Enter how much money you already have saved in a 529 plan or set aside for college. Type $0 if you are just getting started.
Planned Monthly Contribution: Enter how much you plan to put into the 529 account each month. You can use the plus and minus buttons to adjust by $25.
Expected Annual Return and College Cost Inflation: Set your expected yearly investment return rate and the rate at which college costs go up each year. A common return for a balanced 529 plan is around 6%, and college costs have historically risen about 5% per year. You can use our Inflation Calculator to explore how inflation affects purchasing power over time.
After filling in all eight steps, click Get Results to see your projected savings at college start, your funding status, any shortfall or surplus, and the monthly amount needed to fully fund your goal. The results also include charts showing savings growth over time, a breakdown of contributions versus investment growth, and a year-by-year savings table. Use the built-in What-If Scenario tool to instantly see how changing your monthly contribution or return rate affects your outcome.
What Is a 529 Plan?
A 529 plan is a tax-advantaged savings account designed specifically to help families pay for education expenses. It is named after Section 529 of the Internal Revenue Code. The money you put into a 529 plan grows over time without being taxed, and withdrawals are also tax-free as long as you use the funds for qualified education costs like tuition, room and board, books, and fees.
Why Save with a 529 Plan?
College is expensive, and costs keep rising. According to the College Board, the average annual cost of a four-year public in-state university is about $25,850, including tuition, fees, room, and board. For a private university, that number jumps to roughly $60,920 per year. On top of that, college costs have historically gone up by about 5% each year, which is faster than regular inflation. This means a child born today could face college costs that are nearly double what families pay right now.
A 529 plan helps you get ahead of rising costs by putting the power of compound growth to work. Compound growth means your savings earn returns, and then those returns earn returns too. The earlier you start, the more time your money has to grow. For example, saving $200 per month starting when a child is born can produce far more than saving $400 per month starting when the child is 10, even though the total amount you put in may be similar. To see exactly how doubling time works with different return rates, try the Rule of 72 Calculator.
How This Calculator Helps
This 529 calculator walks you through eight simple steps to build a personalized college savings plan. You enter your child's age, the type of college you're planning for, the annual cost, how many years of school you want to fund, what percentage of the total cost you want to cover from savings, how much you've already saved, your monthly contribution, and your expected investment return and college inflation rates. The calculator then shows you whether you're on track to meet your savings goal or if there's a shortfall. If you want to explore the growth of your savings independently, our Savings Calculator and Future Value Calculator can help you model different scenarios.
Key Numbers to Know
Most families do not cover 100% of college costs from savings alone. On average, families pay about 50% from savings and income. The rest typically comes from scholarships, grants, financial aid, and student loans. That's why the calculator lets you choose what percentage of the total cost you want to cover. Even covering half the cost with a 529 plan can save your child from taking on large amounts of student debt. If your child does need to borrow, our Student Loan Calculator can help you understand the long-term cost of those loans.
When it comes to investment returns, a moderate 529 portfolio has historically earned about 6% per year. Conservative plans may return around 4%, while more aggressive plans could return around 8%. Most 529 plans offer age-based portfolios that automatically shift from aggressive to conservative investments as your child gets closer to college age.

Tips for Getting the Most from Your 529
- Start early. Even small contributions made when your child is a baby benefit from years of compound growth.
- Be consistent. Setting up automatic monthly contributions keeps your savings on track without requiring you to think about it.
- Take advantage of gift contributions. Grandparents and other family members can contribute to a 529 plan, and many states offer tax deductions or credits for contributions.
- Review your plan annually. Use tools like this calculator to check your progress and adjust your contributions if needed.
- Know the rules. If your child gets a scholarship, you can withdraw that same amount from the 529 without paying the usual 10% penalty on earnings. Under the SECURE 2.0 Act, unused 529 funds can also be rolled into a Roth IRA for the beneficiary, subject to certain limits.
Planning for college costs may feel overwhelming, but starting with a clear picture of your goal and a steady savings habit makes a real difference. This calculator gives you that clear picture so you can make smart decisions today for your child's future education. As part of your broader financial plan, consider building an emergency fund, tracking your overall net worth, and planning for your own retirement alongside your child's education savings. If you're also investing through a workplace plan, our 401k Calculator can help you balance both goals, and the Investment Calculator is useful for modeling general portfolio growth over time.
