Understanding Annuity Payouts
An annuity is a contract between you and an insurance company, where you make a lump-sum payment or a series of payments, and in return, the insurer promises to make periodic payments to you, either immediately or at some future date. This calculator helps you understand the potential growth and payout of your investment, considering factors like the initial investment, the length of the annuity term, the expected payout rate, and how often your earnings are compounded.
Investment Amount: This is the total sum of money you plan to invest in the annuity.
Annuity Term: This refers to the duration over which you will receive payments. It can be for a fixed number of years or for your lifetime.
Estimated Annual Payout Rate: This is the projected rate of return you can expect from your annuity investment annually. It's crucial to note that this is an estimate, and actual rates can vary.
Compounding Frequency: This determines how often your earnings are calculated and added to your principal. More frequent compounding generally leads to higher returns over time.
The calculation uses a compound interest formula adapted for annuity payouts to estimate the total value accumulated and the potential total payout over the term.
