How This Was Calculated
This calculation combines compound interest on the principal with the future value of monthly contributions:
Where P = $0.00 (initial), PMT = $1,000.00 (monthly contribution), r = 10% (0.1), n = 12 (monthly compounding), t = 30 years. Each monthly contribution is added, then interest is applied for that period, creating additional compound growth.
