Understanding Annuity Growth

Future Value Formula

FV = PV(1+r)^n + PMT[((1+r)^n - 1) / r]

Combines the future value of your initial investment with the future value of your periodic contributions (ordinary annuity).

Tax-Deferred Advantage

Tax-deferred growth means you don't pay taxes on earnings until withdrawal. This allows compound growth on money that would otherwise go to taxes.

  • Annuity: Growth is not taxed annually
  • Taxable: Dividends and gains taxed each year
  • Over time, this difference compounds significantly
