The user is able to test various interest rates, terms, or contribution amounts to understand how they impact the growth of the annuity. The tool makes the complex calculation of annuity simple, giving one a clear picture of the returns to be expected, and helps people make informed decisions on long-term financial planning.
Work & Installation — Input to Output Summary
Work: Uses standard annuity formulas:
Future Value (FV) of Ordinary Annuity: FV = PMT × [((1 + r)^n – 1) / r]
Present Value (PV) of Annuity: PV = PMT × [1 – (1 + r)^-n] / r
Where PMT = periodic payment, r = interest rate per period, n = number of periods.
Installation: Online tool—no installation required.
Input: Principal/Payment Amount, Interest Rate (%), Number of Periods, Payment Type (Ordinary/Annuity Due).
Output: Future Value, Total Payments, Interest Earned, Periodic Payment Amount.
Example: $10,000 investment, 5% interest, 10 years, monthly payments → FV ≈ $16,386.
