Understanding Annuity Payouts Over 10 Years
An annuity is a financial product sold by insurance companies that provides a steady stream of income over a period of time, typically for retirement. A 10-year annuity payout is a specific type where you receive regular payments for a decade.
This calculator helps you estimate how long your initial investment might last or what your annual withdrawal could be, considering a fixed annual interest rate. It's crucial to understand that annuity calculations can be complex and actual results may vary based on the specific terms of your annuity contract, including fees, charges, and market performance.
How it Works:
The calculator takes into account your initial investment (principal), the annual interest rate your annuity is earning, and the amount you wish to withdraw each year. It then simulates the growth and withdrawal process to project potential outcomes.
- Initial Investment: The lump sum of money you initially put into the annuity.
- Annual Interest Rate (%): The rate at which your investment grows each year, before withdrawals are taken.
- Annual Withdrawal Amount: The fixed amount you plan to take out of the annuity each year.
By inputting these figures, you can get an idea of the sustainability of your withdrawals. For example, if you have a large initial investment and a reasonable interest rate, you might be able to withdraw a significant amount annually for the full 10 years or even longer. Conversely, if your withdrawals are high relative to your investment and interest rate, the annuity may deplete faster than expected.
