Investment Calculation Formulas
Compound Interest Formula:
FV = P × (1 + r/n)^(n×t)
- • FV = Future value
- • P = Principal (initial investment)
- • r = Annual interest rate (as decimal)
- • n = Compounding frequency per year
- • t = Time in years
Future Value of Annuity:
FVA = PMT × [(1 + r)ⁿ - 1] / r
- • FVA = Future value of annuity
- • PMT = Monthly payment
- • r = Monthly interest rate
- • n = Total number of payments
