The best time to start your child's college fund is the day they're born. The second best time is today. The CalcHub College Fund Calculator shows exactly how much you need to save monthly — and what happens if you start earlier, later, or save more or less than you'd planned.

The Core Question: How Much Will College Cost?

Current 4-year costs (tuition, room, board, fees):


  • In-state public university: ~$25,000–$30,000/year → ~$100,000–$120,000 total

  • Out-of-state public: ~$45,000–$55,000/year → ~$180,000–$220,000 total

  • Private college: ~$55,000–$80,000/year → ~$220,000–$320,000 total


With a 4.5% annual tuition inflation rate, those costs roughly double every 16 years. A baby born today facing a private college in 18 years could see costs exceeding $400,000.

That number is alarming. The important thing to remember: you don't need to cover 100% of it yourself.

Monthly Savings Needed by Target Coverage Level

Assume your child is a newborn, target is 4-year in-state public in 18 years (~$190,000 future value at 4.5% inflation):

Monthly SavingsProjected Balance at 18 (6% return)Coverage %
$100~$38,700~20%
$200~$77,400~41%
$300~$116,100~61%
$400~$154,800~82%
$475~$184,000~97%
For a private school at $350,000+ future value, multiply these targets roughly by 1.8–2x.

The Cost of Waiting

The calculator makes this painfully clear:

Start AgeMonthly Needed to Reach $150,000 by 18 (6% return)
Birth~$385/month
Age 3~$500/month
Age 6~$690/month
Age 10~$1,150/month
Age 14~$2,600/month
Starting 6 years late costs you an extra $300+/month for the same outcome.

Setting a Realistic Goal

Most financial advisors suggest targeting 1/3 coverage from savings, 1/3 from current income/scholarships, and 1/3 from student work/loans. That makes the monthly savings target much more achievable than trying to pre-fund everything.

Should I fund my retirement or my child's college?

Both matter, but financial advisors consistently say: fund your retirement first. Your child can borrow for college; you can't borrow for retirement. The calculator can run both scenarios side by side.

What if my child gets a full scholarship?

529 funds can be rolled over to another beneficiary, used for graduate school, or since 2024, partially rolled into a Roth IRA (up to $35,000 lifetime limit, subject to rules). The money isn't lost.

Can grandparents contribute?

Absolutely. Grandparent 529 contributions no longer impact FAFSA financial aid calculations (as of 2024 rules), making this one of the cleanest gift options for college savings.
