Future College Cost & Sinking Fund Formula
Future College Cost = Current Cost × (1 + Inflation Rate)^Years to College; PMT = Target / [((1 + r)^n - 1) / r]- Higher Education Inflation: College costs historically inflate at 4% to 5% annually, outpacing general headline CPI.
- Tax-Advantaged 529 Growth: Contributions grow 100% tax-free at the federal level and withdrawals for qualified education expenses are tax-free.
- State Tax Deductions: Over 30 states offer state income tax deductions or tax credits for contributing to your home state 529 plan.
Step-by-Step Worked Example
Scenario: Parents saving for a newborn (18 years until college) targeting an in-state 4-year public university currently costing $25,000/year ($100,000 total)
Calculation Steps:
- Projected Future 4-Year Cost = $100,000 × (1 + 0.045)^18 = $220,848
- Monthly Contribution Required to reach $220,848 with 7% growth = ~$512/month
Result: Projected future college cost is $220,848, requiring a monthly 529 contribution of approximately $512.
