Formula and Logic
This tool uses the future value of an ordinary annuity formula: FV = P * [((1 + r)^n - 1) / r], where P is the periodic payment, r is the periodic interest rate, and n is the total number of periods. The calculation adjusts for the selected compounding frequency.
Practical Notes
- Interest rates significantly impact growth; higher rates lead to larger future values.
- More frequent compounding (e.g., monthly vs. annually) increases the effective yield due to interest on interest.
- Tax implications vary by account type (e.g., Traditional IRA vs. Roth IRA); consult a tax advisor for personalized advice.
- Regular contributions, even small amounts, build substantial savings over time through compounding.
