529 Plan Contribution Calculator
Calculate how your 529 plan contributions grow over time. Project future value with monthly deposits, expected returns, and years until college.
Find out how much to save monthly to reach your college fund goal. Set a target amount, timeline, and expected returns to calculate required contributions.
Knowing how much to save each month for your child's education turns an overwhelming goal into a manageable plan. With college costs projected to reach $250,000-$400,000+ for a four-year degree by 2040, starting early and saving consistently is essential.
This page works backward from your target: enter how much you'll need, when you'll need it, and your expected investment return, and it gives you a monthly savings number you can compare with the rest of your household budget.
The result often looks more manageable when the timeline is long and more demanding when the start is delayed, which is exactly the planning signal most parents need.
Parents usually need a contribution target, not another reminder that college is expensive. This page shows what the monthly commitment looks like under your own assumptions.
Required Monthly = (Target โ Current ร (1 + r)^n) ร r / ((1 + r)^n โ 1)
Where:
Target = College cost goal
Current = Current savings
r = Monthly rate of return (Annual / 12)
n = Total months until collegeResult: $498/month
To reach $200,000 in 15 years starting with $10,000 at 7% return, you need to save approximately $498/month. Your total contributions would be $99,640 plus the initial $10,000, with investment growth providing the remaining ~$90,000.
Research current costs for target schools, then inflate at 4-5% per year to project future costs. Include tuition, room and board, books, and personal expenses. A four-year public university averages $100,000-$120,000 total today; project forward based on your child's age.
Starting at birth gives you 18 years of compound growth and requires roughly half the monthly savings compared to starting at age 8. Each year of delay increases the required monthly contribution by approximately 10-15%. The math heavily rewards early starters.
Start with what's comfortable and automate monthly transfers. Increase contributions annually โ even $25/month increases each year compound significantly. Use windfalls, tax refunds, and birthday gifts to make lump-sum deposits that accelerate progress.

College costs have been rising 3-5% annually. A public university costing $25,000/year today could cost $40,000-$50,000/year in 15 years. Private universities currently averaging $60,000/year could reach $90,000-$120,000/year. Use realistic projections.
Any savings reduces future student debt. Aim to cover at least 50% of projected costs. The rest can come from financial aid, scholarships, work-study, and reasonable student loans. Saving something is always better than saving nothing.
Generally, pay off high-interest debt (credit cards) first, as the interest costs exceed investment returns. For low-interest debt (mortgage, federal student loans), save simultaneously โ the tax advantages and compound growth of early college savings are valuable.
A diversified stock portfolio has historically returned 7-10% annually over long periods. Use 6-7% for a moderate estimate with a mix of stocks and bonds. The further from college, the more aggressive you can invest, so younger children's funds may earn more.
Yes, but the monthly amount increases significantly. Starting at birth requires roughly $500/month for $200,000 in 18 years. Starting at age 10 requires about $1,200/month for the same goal in 8 years. Earlier is better, but later is better than never.
529 plans are the top choice for tax-free growth. Coverdell ESAs allow $2,000/year with more investment options. Custodial accounts (UGMA/UTMA) and taxable brokerage accounts are alternatives with less tax advantage but more flexibility.
