College Savings Calculator
Estimate how much you need to save each month to reach your college savings goal.
How is monthly college savings calculated?
This calculator takes your years until college (college start age minus current age), projects how much your existing savings will grow at your expected annual return, then figures out the remaining gap between that projected balance and your total cost target. It spreads that gap evenly across the remaining months using a standard sinking-fund formula, the same approach used for other long-term savings goals like a house down payment, so the monthly figure accounts for compound growth on your future contributions too, not just simple division.
Why does the total cost target vary so much?
A four-year college cost target can range enormously — in-state public tuition, room, and board often totals $80,000-$110,000 over four years, while private universities frequently exceed $200,000-$300,000 total, and costs continue rising faster than general inflation most years. This calculator treats your input as already expressed in future, "at enrollment" dollars for simplicity, so if you're estimating in today's dollars, consider inflating your target cost upward, especially for children who are many years away from college.
What if I can't hit the monthly number?
If the suggested monthly savings feels out of reach, even a smaller consistent contribution compounds meaningfully over a decade or more, and you can always increase contributions as income grows. Many families also plan to cover part of college costs through financial aid, scholarships, or student loans rather than fully funding the estimate through savings alone — use this number as a target, not a strict requirement.
Frequently Asked Questions
How much should I save monthly for my child's college?
It depends heavily on your child's age, your cost target, and expected investment return — a newborn's family has 18 years to spread contributions across, while a family starting at age 12 has far less time and needs higher monthly amounts. Use the calculator above with your specific numbers for an accurate target.
What is a 529 plan?
A 529 plan is a tax-advantaged investment account specifically for education expenses — contributions grow tax-free and withdrawals are tax-free when used for qualified education costs like tuition, room, and board. Most states offer their own 529 plan, and some provide state tax deductions for contributions.
How much does a 4-year college degree actually cost?
In-state public college typically totals $80,000-$110,000 over four years including tuition, room, and board, while private universities often run $200,000-$300,000 or more. Costs vary significantly by state and institution, so research your specific target school when possible.
When should I start saving for college?
The earlier the better, since more years allow smaller monthly contributions to grow into a larger total through compound returns. Starting when a child is born rather than waiting until age 10 can cut the required monthly contribution significantly for the same total goal.
What if I'm behind on college savings?
Even partial savings meaningfully reduce future student loan burden, and many families cover the remaining gap through financial aid, scholarships, or loans. Increasing contributions as income grows, or having grandparents contribute directly to a 529 plan, are common ways to catch up.
What rate of return should I expect on college savings?
Many 529 plans use age-based portfolios that start more aggressively (often projecting 6-8% average annual returns) and shift to conservative investments as college approaches. Actual returns vary year to year and are never guaranteed, so treat any projected rate as an estimate, not a promise.
Does financial aid reduce how much I need to save?
It can, but financial aid eligibility depends on income, assets, and the specific school's policies, and isn't guaranteed to cover a specific amount. Most financial planners recommend saving toward a realistic cost target rather than assuming aid will fill the gap, then adjusting once actual aid offers are known.
Should I save for multiple children separately?
Most families use separate 529 accounts for each child since each has a different timeline and cost target, and this calculator is designed to be run once per child. Some 529 plans also allow beneficiary changes, offering flexibility if plans change for one child.
