WHY STARTING EARLY MATTERS SO MUCH
The math of compound interest makes college savings one of the most time-sensitive financial goals a family faces. A family that starts saving for a newborn needs to set aside roughly $300 per month to fund a public university education at a 6 percent average annual return. A family that waits until the child is 10 needs to save over $900 per month to reach the same goal. Waiting five more years to age 15 requires over $2,500 per month.
The difference is not small. Early savings is exponentially more powerful than late savings because compound interest has more time to work. The college savings calculator makes these numbers concrete and specific to your children so you can see exactly what starting today versus waiting costs in monthly savings terms.
Choosing a College Cost Goal
- 2-Year Community College (~$50,000): Includes tuition, fees, books, and living expenses for two years at a community college. An excellent starting point for students who plan to transfer to a four-year university after completing general education requirements.
- 4-Year Public University (~$120,000): Covers estimated total costs including tuition, fees, room, board, and books for four years at an in-state public university based on current averages with modest inflation built in.
- 4-Year Private University (~$240,000): Covers estimated total costs for four years at a private university. Private university costs vary enormously and this figure represents a middle estimate.
- Custom Amount: Enter your own target based on specific schools, anticipated scholarship funding, or the percentage of costs you plan to cover.

What Is a 529 College Savings Plan?
A 529 plan is a tax-advantaged savings account specifically designed for education expenses. Contributions are made with after-tax dollars but the account grows tax-free and withdrawals for qualified education expenses are completely federal tax-free. Many states also offer state income tax deductions for 529 contributions made by residents. 529 plans can be used for tuition, fees, books, room and board, and certain other qualified expenses at accredited colleges and universities as well as K-12 tuition up to $10,000 per year.
How Much of College Should Parents Fund?
Financial planners typically recommend that parents aim to fund between 50 and 75 percent of anticipated college costs rather than 100 percent. Students are expected to contribute through part-time work during school, summer earnings, merit scholarships, grants, and reasonable student loans. Trying to fund 100 percent of college costs at the expense of retirement savings is generally not recommended. Retirement savings should take priority over college savings because retirement cannot be financed while college can.
FREQUENTLY ASKED QUESTIONS
Is this calculator free?
Yes, completely free with no account required.
What investment return rate should I use?
The calculator defaults to 6 percent which reflects a moderate long-term investment return for a diversified portfolio. Conservative investors might use 4 to 5 percent. Investors comfortable with more equity exposure might use 7 to 8 percent. Higher return assumptions reduce the required monthly savings but carry more investment risk.
What if I already have some money saved?
Enter your existing savings in the Current Total Savings Already Saved field. The calculator accounts for the future value of those savings and reduces the required monthly contribution accordingly.
Can I plan for more than one child?
Yes. The calculator supports up to three children with individual savings plans for each. Click Add Another Child to add additional children.
Should I use a 529 plan for these savings?
A 529 plan is generally the best vehicle for college savings due to its tax advantages. Consult with a financial advisor about which 529 plan is right for your state and situation. This calculator shows how much to save regardless of which account type you choose.
