College Savings Calculator
Calculate how much to save monthly for college from child age, college cost, and returns. Enter values for instant results with step-by-step formulas.
Formula
Monthly = (Inflated Cost - Current Savings FV) ÷ FV Annuity Factor
The calculator projects total college costs forward using the education inflation rate, subtracts the future value of current savings, then calculates the monthly contribution needed using the future value of an annuity formula based on the expected investment return rate.
Worked Examples
Example 1: Newborn — Public University Plan
Problem: How much to save monthly for a newborn to attend a public university ($25,000/year, 4 years) with 5% inflation and 7% returns?
Solution: Years until college: 18\nToday's total cost: $100,000\nInflated cost at age 18-21: $25,000 × (1.05^18 + 1.05^19 + 1.05^20 + 1.05^21) = $258,637\nMonthly savings needed: $258,637 ÷ FV annuity factor = $555.12
Result: Monthly savings: $555.12 | Total contributions: $119,906
Example 2: Age 8 — Private University
Problem: A child is 8 years old. Parents have $15,000 saved. Private university costs $55,000/year for 4 years. 5% inflation, 6% returns.
Solution: Years until college: 10\nInflated total cost: $55,000 × (1.05^10 + 1.05^11 + 1.05^12 + 1.05^13) = $384,876\nCurrent savings at college: $15,000 × 1.06^10 = $26,863\nRemaining needed: $358,013\nMonthly contribution: $2,172.48
Result: Monthly savings: $2,172.48 | Gap: $358,013
Frequently Asked Questions
How much does college cost and how fast are costs rising?
As of 2024, the average annual cost of college in the United States varies significantly by institution type. Public in-state universities average $22,000-$28,000 per year including tuition, fees, room, and board. Public out-of-state universities average $38,000-$45,000. Private universities average $50,000-$60,000, with elite institutions exceeding $80,000. College costs have historically risen at 5-8% annually, roughly double the general inflation rate. Over the past 20 years, tuition at four-year public universities has increased by approximately 175%. This means a child born today could face costs of $50,000-$100,000 per year at a public university by the time they enroll.
What is a 529 plan and should I use one for college savings?
A 529 plan is a tax-advantaged investment account specifically designed for education expenses. Contributions grow tax-free, and withdrawals for qualified education expenses (tuition, fees, books, room and board, computers) are also tax-free at the federal level. Many states offer additional tax deductions or credits for contributions. There are two types: education savings plans (investment accounts) and prepaid tuition plans (lock in current rates). The account owner maintains control, can change beneficiaries to other family members, and there are no income limits for contributors. Starting in 2024, unused 529 funds can be rolled into a Roth IRA (up to $35,000 lifetime) for the beneficiary, reducing the risk of over-saving.
What investment return rate should I assume for college savings?
The appropriate assumed return rate depends on your investment allocation and time horizon. For long time horizons (10+ years), a diversified portfolio of stocks and bonds has historically returned 7-10% annually before inflation, so assuming 6-8% is reasonable. As college approaches, shift to more conservative investments: when your child is 10-14 years from college, assume 5-7%; within 5 years, assume 3-5% as you move toward bonds and cash equivalents. Most 529 plans offer age-based portfolios that automatically become more conservative as the enrollment date approaches. It is better to use conservative estimates and end up with extra funds than to be overly optimistic and face a shortfall.
When should I start saving for my child's college education?
The ideal time to start saving is as early as possible, ideally at birth or even before. Starting at birth gives you 18 years of compound growth, which dramatically reduces the monthly savings needed. For example, to accumulate $200,000 by age 18 at a 7% return: starting at birth requires about $475/month, starting at age 5 requires about $730/month, and starting at age 10 requires about $1,350/month. Even small early contributions make a significant difference due to compounding. If you start at birth with just $50/month at 7% returns, you will have approximately $23,000 by age 18, with nearly half coming from investment growth rather than contributions.
How do financial aid and scholarships affect college savings goals?
Financial aid and scholarships can significantly reduce the amount you need to save, but should not be relied upon entirely. Merit-based scholarships are competitive and not guaranteed. Need-based financial aid considers family income, assets, and the number of children in college. Having a 529 plan has a relatively small impact on financial aid eligibility because parent-owned 529 accounts are assessed at a maximum rate of 5.64% on the FAFSA, compared to 20% for student-owned assets. The average scholarship covers about $7,000-$15,000 per year. A balanced approach is to save as if you will receive no aid, but plan to apply for every scholarship and grant available. Any aid received becomes a bonus that reduces loans needed.
