529 College Savings Calculator

What is a 529 college savings calculator?

A 529 college savings calculator helps families estimate how much their college savings could grow based on current contributions, expected investment returns, and the number of years until college begins. It also estimates future tuition costs by adjusting today’s expenses for college inflation.

Because college costs have historically risen faster than general inflation, planning early and modeling different scenarios can make a meaningful difference in how much financial stress you face later.

How 529 plans grow over time

529 plans are tax-advantaged education savings accounts. Earnings grow tax-deferred, and withdrawals are generally tax-free when used for qualified education expenses.

The power of compounding means that contributions made earlier typically have a larger impact than larger contributions made later. Even modest monthly deposits can accumulate significantly over 15–18 years.

How college inflation affects your savings target

Tuition and related costs tend to increase annually. This calculator adjusts today’s estimated annual college cost by a selected college inflation rate to project future expenses.

For example, a $25,000 annual cost today could grow substantially over 15 years depending on the inflation rate used. Modeling conservative and aggressive scenarios can help families plan more confidently.

How much should you save for college?

There’s no universal answer. Factors include:

• Public vs private university expectations
• In-state vs out-of-state tuition
• Scholarship likelihood
• Family income and financial aid eligibility
• Whether parents are also balancing student loan payments

529 plan vs other college savings options

Some families compare 529 plans with brokerage accounts or custodial accounts. A 529 offers tax advantages but is limited to qualified expenses. Brokerage accounts provide flexibility but do not offer the same tax benefits.
