Fixed annuities are a popular choice for individuals who want a guaranteed interest rate and a stream of income they can’t outlive. With a fixed annuity, the principal investment and a specified interest rate are both guaranteed. If you are more of a conservative investor, a fixed annuity may appeal to you. Fixed annuities offer steady and guaranteed growth. In addition fixed annuities also offer tax-deferral to help your money grow faster and a lifetime income option to keep your retirement secure.
