Calculation Methodology
Standard Financial Formulas Used:
1. Future Value of Current Balance:
FV = PV × (1 + r)^n
$20,000 × (1.07)^26 = $116,140
2. Growing Annuity (Regular Contributions):
FV = P × [((1 + r)^n - (1 + g)^n) / (r - g)]
Where P = $7,200 (Year 1 total), r = 7%, g = 3%, n = 26
3. Additional Contributions (Inheritance/Bonus):
Each contribution grows at its product-specific rate:
• IRA/Taxable: Market rate (e.g., 7%)
• IUL: Capped rate (participation × cap)
• Fixed Annuity: Guaranteed rate (e.g., 3%)
4. Monthly Retirement Income (4% Rule):
Monthly = (Total Balance × 0.04) ÷ 12
Note: Additional contributions use product-specific return rates entered by user. IUL products use participation rates and caps as specified.

This calculator is for illustrative purposes only and does not constitute financial advice.
Past performance of the S&P 500 does not guarantee future results. The 4% rule is a general guideline based on historical market data; actual sustainable withdrawal rates may vary based on market conditions, inflation, sequence of returns risk, and individual circumstances.
Annuity rates, caps, and participation rates are subject to change by issuers. Tax implications vary based on account types and individual tax situations.
All projections assume constant rates of return and do not account for market volatility, taxes, fees, or inflation unless explicitly modeled.
