How to Use This College Savings Calculator
- 1
Enter the child's current age
This determines how many years you have until college. Starting at birth gives ~18 years of compound growth; starting at age 10 gives only 8 years, requiring much larger monthly contributions.
- 2
Set the target college cost
In-state public university averages ~$27,000/year (tuition + room/board). Private universities average ~$58,000/year. Community college averages ~$12,000/year. Costs increase 3-5% annually.
- 3
Choose your savings vehicle
529 plans offer tax-free growth for education expenses. Coverdell ESAs have $2,000/year limits. Custodial accounts (UTMA/UGMA) have no limits but less tax efficiency. 529 is usually the best choice.

Review monthly savings needed
The calculator shows monthly contributions needed to reach your goal, accounting for investment growth (historically 7-8% for stock-heavy 529 portfolios). College Savings may offer a tax deduction for 529 contributions.
Example Calculation
Let's plan college savings for a newborn in College Savings.
Goal: fund 4 years at an in-state public university. Current cost: $27,000/year × 4 = $108,000. With 4% annual cost inflation over 18 years, projected cost: ~$218,000. Using a 529 plan with 7% average annual return, investing from birth.
Result: Required monthly contribution: ~$530/month from birth. If you wait until the child is 5, the monthly contribution jumps to ~$835. Starting early makes a dramatic difference. Additionally, College Savings offer a state income tax deduction for 529 contributions — saving 3-10% immediately on contributions. Some states allow up to $10,000/year in deductible contributions per beneficiary.
What Affects Your Results
Starting Age
Starting at birth vs. age 5 doubles the required monthly contribution (~$530 vs. ~$835 for a $218,000 goal). Compound interest is most powerful with the longest time horizon.
College Cost Inflation
College costs historically increase 3-5% annually — faster than general inflation. A $27,000/year school today will cost $55,000-$65,000/year in 18 years at 4% inflation.
Investment Returns
529 portfolios invested heavily in stocks have historically returned 7-10% annually. Age-based portfolios reduce stock allocation as the college date approaches, lowering expected returns but also risk.
State Tax Benefits
College Savings may deduct 529 contributions from state income tax. At a 5% state tax rate, a $10,000 contribution saves $500 in taxes — an immediate 5% return before any investment gains.
College Choice
In-state public (~$27K/yr), out-of-state public (~$45K/yr), private (~$58K/yr), and community college (~$12K/yr) have vastly different costs. Saving for the cheaper option and upgrading if investments outperform is a prudent strategy.
Tips for College Savings Residents
- Check if College Savings offers a tax deduction or credit for 529 plan contributions. Over 30 states do, saving you 3-10% immediately. You don't have to use your own state's plan — but the tax benefit is usually state-specific.
- You can superfund a 529 with up to 5 years of gift tax exclusion at once ($90,000 per beneficiary in 2026) without triggering gift tax. This front-loads compound growth and is a powerful estate planning tool.
- FAFSA treats 529 plans owned by parents as parental assets (5.64% expected contribution vs. 20% for student assets). Keep 529s in parents' names, not grandparents' — grandparent-owned 529s are treated differently.
- Unused 529 funds can be transferred to another family member (sibling, cousin, parent, even yourself for continuing education) without tax or penalty. The SECURE 2.0 Act also allows rolling unused 529 funds to a Roth IRA (lifetime max $35,000, subject to conditions).
- Age-based portfolios within 529 plans automatically shift from stocks to bonds as the child approaches college age — reducing risk of market drops right when you need the money.
