Why Today's $25,000 Tuition Becomes a $60,000 Problem
Meet Dana. She has a one-year-old daughter, a 529 account she opened with $2,000, and a number in her head: $25,000 a year. That's roughly what a public, in-state four-year university costs today for tuition, fees, room, and board. Dana figures she's saving toward a $100,000 problem. She's not. She's saving toward a number nearly twice that size, and the gap is what the brochures never mention.
Here's the math she avoided. Her daughter won't enroll for about 17 years. College costs haven't been climbing at the general inflation rate of 2-3% a year. They've historically run closer to 5% annually over the long term. Run $25,000 forward 17 years at 5%, and that first-year cost becomes roughly $57,000. Multiply across four years of rising tuition and the total sticker price lands near $245,000 for one in-state degree. The private-school version is worse: a $58,000-per-year private college today projects past $130,000 per year, or well over $560,000 for four years.
That's the trap of saving toward today's number. If Dana aims at $100,000, she'll arrive at freshman year with less than half of what she needs and call it a shortfall she didn't see coming. The cost didn't surprise her. The compounding did.
Projecting matters because it converts a vague worry into a savings target you can actually hit. Once you know the future cost is closer to $245,000 than $100,000, you can work backward. Dana has 17 years. To fund that in-state total, she'd need to save roughly $650 a month assuming her 529 grows around 6% annually. Aiming at the un-projected $100,000 figure, she'd have saved about $265 a month and arrived $130,000 short.
The point isn't to scare you into funding 100% of a private degree. Plenty of families cover a slice and bridge the rest with scholarships, in-state tuition, community-college transfers, and student contributions. The point is to project honestly so your slice is a deliberate choice, not an accident. A $25,000 mistake in your target today compounds into a six-figure surprise at orientation. Enter your child's age, your starting balance, and an assumed return, and this calculator shows the projected cost and the monthly savings that actually closes it.
