Calculate the accumulation of a fixed annuity
Description
The Annuity Calculator helps you project the future value of a fixed annuity investment. By specifying an initial investment amount and the expected interest rate, you can see how your principal will grow over a set number of years through the power of annual compounding.
Inputs
- Initial Investment: The starting principal amount deposited into the annuity ($).
- Growth Period: The number of years you plan to let the investment grow.
- Annual Interest Rate: The guaranteed or expected annual return percentage (%).
Outputs
- Future Value: The estimated total value of the annuity at the end of the growth period.
- Total Interest: The total amount earned from compounding interest over the term.
Chart
- Growth Area Chart: Visualizes the increasing value of the annuity year-over-year.
“Good to Know”
- Annuities are often used as a long-term retirement planning tool to provide a predictable future sum.
- A “fixed annuity” offers a guaranteed rate of return for a specific period, making it a lower-risk investment compared to stocks.
- This calculator assumes annual compounding; actual annuity products may compound monthly or quarterly, which can slightly increase the final total.
