What Annuity Calculator does

An annuity calculator that lets users model the future value of an annuity by inputting an initial investment, interest rate, withdrawal amount, and duration. It projects how long funds might last and what the eventual balance could be, supporting both annuity due and immediate annuity options to help investors forecast retirement income or understand how regular contributions grow over time. The tool is designed for individuals planning retirement income, financial advisors, and anyone evaluating structured payout options. Bankrate’s version stands out for its integration within a broader suite of financial calculators, offering a clean, grid-based interface that groups annuity tools alongside savings, CD, and retirement planners. While other free calculators focus solely on annuity math, Bankrate’s version provides contextual explanations of variables like interest rate and duration, and allows users to switch between immediate and due annuity types within the same workflow, making it easier to compare scenarios without leaving the page.

Is it right for you

Best for

Retirement planners and financial advisors who need a quick, visual way to compare how different interest rates, contribution amounts, and annuity types affect long-term income streams.

Limitations

  • Results are based on fixed interest rate assumptions and do not account for market volatility or fees.
  • No option to adjust contribution frequency independently of withdrawal frequency; both are tied to the same annual or monthly cycle.
  • Output is an estimate only; actual annuity performance may vary based on insurer terms and real-world rate changes.
