Introduction: Lifetime annuities are financial instruments that provide a guaranteed income stream for an individual’s entire life. Calculating the cost of a lifetime annuity is essential for retirement planning and financial decision-making.
Formula: To calculate the cost of a lifetime annuity, we use the formula:
Cost = Principal × [1 – (1 + Annual Interest Rate) ^ -Number of Years] / Annual Interest Rate
Where:
- Principal is the initial investment amount.
- Annual Interest Rate is the interest rate as a percentage.
- Number of Years is the duration of the annuity.
How to Use:
- Enter the Principal Amount, which is the initial investment.
- Input the Annual Interest Rate as a percentage.

Example: Suppose you have $100,000 to invest, an annual interest rate of 5%, and you want to calculate the cost of a lifetime annuity for 20 years. Input these values into the calculator and click “Calculate” to find the cost.
