529 Plan Growth Formulas
Compound Interest Formula
Future Value with Regular Contributions:
FV = PV × (1 + r)ⁿ + PMT × [(1 + r)ⁿ – 1] / r
Example: PV = $5,000, PMT = $200, r = 6%/12 = 0.5%, n = 120 months → FV = $42,851
Inflation Adjustment
Real Future Value Formula:
Real FV = Nominal FV / (1 + i)ⁿ
Example: Nominal FV = $42,851, i = 2.5%, n = 10 years → Real FV = $33,457
Monthly Contribution Growth
Annual Contribution Increase:
PMT_year = PMT_start × (1 + g)ⁿ
Example: Starting PMT = $2,400/year, g = 3%, n = 10 years → Year 10 PMT = $3,224/year
