What Is an Annuity Calculator?
An annuity calculator is a financial planning tool that estimates how an annuity may grow or how much income it may pay over time. It commonly uses starting balance, monthly contribution, interest rate, fees, accumulation years, payout years, and payment timing.
Annuities can be used for retirement income planning because they may provide scheduled payments over a selected period or for life, depending on the annuity contract.

What This Annuity Calculator Shows
This calculator gives a practical estimate using common annuity planning factors.
Future Annuity Value
The estimated value after accumulation years, contributions, returns, and fees.
Monthly Payout
The estimated monthly income the annuity balance may support during payout years.
Total Contributions
The estimated amount contributed including starting balance and monthly deposits.
Interest Earned
The estimated growth from interest or investment return after contributions.
Total Fees
The estimated fee impact based on the selected annual fee assumption.
Income Gap
The difference between estimated monthly payout and your desired monthly income.
Annuity Calculator Example
Suppose you start with $100,000, contribute $500 per month, earn an estimated 5% annual return, and save for 20 years.
The calculator estimates future annuity value, interest earned, total contributions, monthly payout estimate, total payout, and whether the projected payout may meet your desired monthly income goal.
Future Value vs. Annuity Payout
Future value estimates how much your annuity may grow during the accumulation period. Annuity payout estimates how much monthly income that balance may support during the payout period.
Both views can be helpful when planning retirement income or comparing annuity scenarios.
Annuity Fees and Inflation
Fees can reduce annuity growth and payout estimates. Inflation can also reduce purchasing power over time, which means a future monthly payout may buy less than the same amount today.
This calculator includes fee and inflation assumptions to help create a more practical estimate.
