Calculator for Savers

What This Calculator Does

The College Savings Calculator helps you answer three of the most stressful questions parents face: How much will college actually cost when my child enrolls? How much should I be saving each month to be on track? And what's my funding gap if I continue at my current pace?

It projects the future cost of college using education-specific inflation — historically 4–6% per year, which is meaningfully higher than general consumer price inflation. It calculates how your current savings and monthly contributions will grow over time, and shows you exactly how much of the bill your savings plan will cover, and how much it won't. You can model four college types, adjust your return and inflation assumptions, and see a year-by-year picture of your savings balance versus your target.

When Should You Use This?

• You just had a baby and want to know how much to contribute to a 529 each month to reach a realistic goal.
• Your child is 5–10 years old and you want to know whether you're on track or falling further behind.
• You received a raise and are deciding whether to redirect some of it toward college savings.
• You're comparing school types — public in-state versus private — and want to see the real cost difference in future dollars.
• A grandparent wants to contribute and you need a concrete monthly number to share with them.
• Your teenager is 13 or 14 and you need an honest reality check on how much you have versus how much you'll actually need.

How to Read Your Results

The large number at the top is the projected total cost of college in future dollars. This is what you'll actually pay — not what tuition costs today, but what it will cost after years of price increases compound. For most families, this number is higher than expected, and that's the point: it's meant to replace vague anxiety with a concrete planning target.

Below that, four key metrics tell the full story:

• Projected Savings: What your current balance plus monthly contributions will grow into by enrollment, at your chosen return rate. This is what you'll have in the account when the first tuition bill arrives.
• Funding Gap: The difference between what college will cost and what your savings will cover. This is the number you want to shrink — either by saving more, earning more, or planning for partial coverage through loans, aid, or work-study.
• % Funded: The single most actionable summary. Under 40% with a child over 10 means you need a plan adjustment. Under 25% means the conversation about strategy needs to happen now, not later.
• Monthly Savings Needed: The exact contribution required starting today to fully fund the projected cost. Compare it to what you're currently saving — the difference is your monthly gap.

The funding progress bar turns the math into an instant visual. A bar at 30% with your child already in middle school is a very different situation than a bar at 30% with a two-year-old — even though the number looks the same.

A Real-World Example

Meet Priya, 34, whose son Rohan is 5 years old. She and her husband want to send Rohan to a public in-state university. The average total cost of attendance today is about $28,000 per year — tuition, room and board, books, and fees combined. They have $5,000 in a 529 plan and are contributing $300 per month, invested in an age-based fund targeting a 6% average annual return.

College is 13 years away. With 5% education inflation applied each year, that $28,000 school will cost approximately $52,700 per year by the time Rohan is 18 — a 4-year total of just over $213,000. Priya's projected savings at that point: roughly $82,000. Coverage: about 38%. Funding gap: around $131,000.

That gap sounds overwhelming until Priya uses the "What If" scenario tool. Adding just $100 more per month — going from $300 to $400 — raises her projected savings to about $109,000 and coverage to 51%. Adding $200/month gets her to 64%. She decides to increase by $150/month now and revisit the calculator each year when their income changes. That's the decision this tool is designed to support.

Three Common Mistakes to Avoid

1. Using general inflation (3%) instead of education inflation (5–6%)

This is the most common and consequential planning error parents make. College costs have consistently outpaced general consumer price inflation — the College Board has tracked average annual increases of 4–6% over the past two decades. If you plug in 3% inflation for a 15-year horizon, you'll underestimate future costs by 30–40%. The difference between 3% and 5% over 13 years on a $28,000/year cost is roughly $40,000–$60,000. This calculator defaults to 5% education inflation as a reasonable middle estimate. If you're targeting a highly selective private university, consider 5.5–6%.

2. Planning for tuition only and ignoring total cost of attendance

Many parents see their state's published in-state tuition figure — perhaps $12,000–$14,000 per year — and plan around that number. But the total cost of attendance is dramatically higher. On-campus housing and a meal plan typically add $12,000–$16,000 per year. Books, supplies, personal expenses, and travel home add another $3,000–$5,000. The total bill at an "affordable" public school commonly exceeds $28,000–$32,000 per year once all costs are included. This calculator uses total cost of attendance figures, not tuition alone, which is why the numbers may look higher than you expect — and why they're more accurate.

3. Delaying because the initial monthly contribution feels too small to matter

Parents often hesitate to open a 529 because they can only commit $50 or $75 a month. The math says: start anyway. With 15+ years of compounding, even modest contributions accumulate significantly. Starting at birth with $100/month at a 6% return produces over $30,000 by age 18 — enough to cover a full year at many state schools. Starting the same $100/month at age 10 produces less than $14,000 by age 18. The compounding advantage of early years is irreplaceable. Every month you delay is the most expensive month in your college savings timeline, because it's the month that loses the most compounding runway.

What the Numbers Don't Tell You

This calculator models a specific, controlled scenario with fixed assumptions. Real life is more nuanced. A few factors the calculator cannot account for:

• Financial aid and merit scholarships can dramatically reduce your actual out-of-pocket cost. Many families — particularly middle-income households with demonstrated need, or high-achieving students at selective schools — receive substantial aid. Your actual funding gap may be meaningfully smaller than what the calculator shows.
• Market volatility means your investment return won't be a smooth 6% every year. A 6% long-run average might look like +18% in one year and -12% the next. Age-based 529 funds address this by gradually shifting toward bonds as your child approaches college age, reducing sequence risk.
• Your child's school choice will reshape everything. A child who earns a full athletic or academic scholarship, chooses community college for the first two years, attends a less expensive regional school, or studies abroad changes the numbers entirely. So does a child who decides on medical school or law school after the bachelor's degree.
• 529 state tax deductions are not modeled here. In many states, contributions receive a deduction from state income taxes — effectively increasing your after-tax return. This benefit can be worth hundreds of dollars per year, and it tilts the math further toward starting early and contributing consistently.

Treat this calculator's output as a useful planning anchor, not a guarantee. Review it annually — tuition costs change, your income changes, and your child's likely trajectory becomes clearer over time. The goal isn't to predict the future perfectly; it's to make a plan based on the best available information, and to adjust that plan as things evolve.
