529 college savings calculator — how much to save each month for your child's college

Short answer. Put in your child's age, a year of college at today's prices, how many years and how much of it you want to cover, plus your savings and expected return: you see the goal when college starts and the monthly amount to get there. Tax-free growth: 529 earnings grow federally tax-free; withdrawals for qualified education expenses are tax-free (IRS Publication 970).

529 plan · college savings · by age

Your college savings goal — and the monthly amount to reach it

Put in your child's age, a year of college at today's prices, how many years and how much of it you want to cover, plus your savings and expected return: you see the goal when college starts and the monthly amount to get there. No sign-up.

  1. Compare your state's 529 plan — many states give a tax break.
  2. Set up an automatic monthly contribution.
  3. Share the gift link with grandparents before birthdays and holidays.

Arithmetic only, with your assumptions: cost grows by your inflation rate each year until college; savings grow by your expected return, compounded yearly; contributions at the end of each year. Every year of college is priced at the first year's cost. Not investment advice: returns are not guaranteed.

The return and the college inflation rate are your assumptions, not predictions; investments can lose value. Many states give a tax break for their own plan — check your state's 529.

Questions

How much should I save for college each month?

It depends on the cost, the years left and the return. The calculator grows today's cost to the first year of college, subtracts what your savings will grow to, and spreads the rest over the years left.

How much should be in a 529 by age?

Put in your child's age: the year-by-year sheet shows the balance you need each birthday to stay on track.

What can a 529 pay for?

Qualified education expenses — tuition, fees, books, supplies, equipment and, for students enrolled at least half-time, room and board within the school's cost of attendance (IRS Publication 970).

Can grandparents contribute?

Yes. In 2026 each person can give up to $19,000 to each child without using their lifetime exemption, and 529 gifts can be spread over five years for gift-tax purposes.

Is it free? Do I need to sign up?
