Annuity Growth and Distribution
What is an Annuity?
An annuity is a financial contract between you and an insurance company. You pay a premium (lump sum or series of payments), and in return, the company provides regular payments during the payout phase. Annuities have two phases: accumulation (where your money grows tax-deferred) and payout (where you receive income).
Fixed annuities offer guaranteed interest rates and predictable returns, making them lower risk but with limited growth potential. Variable annuities are tied to investment performance and offer potentially higher returns but with more risk. Annuities are often used for retirement income planning to provide guaranteed income streams. For comprehensive retirement planning, see our Retirement Savings Calculator to project overall retirement savings.
How to Use This Calculator
Enter your premium amount, annuity type (fixed or variable), interest or growth rate, growth period (accumulation years), and payout period (distribution years). The calculator shows your annuity value at the start of payout, monthly payout amount, total payouts, and total growth.
Use the chart to visualize how your annuity grows during accumulation and how payouts work during distribution. Compare different scenarios to understand how growth rates and time periods affect your income.
Formula Explained
The annuity calculation has two phases:
Payout: Monthly Payment = Value / (Number of Months)
Where:
- Premium = Initial payment to purchase annuity
- r = Annual interest/growth rate
- n = Number of years in accumulation phase

Tips for Best Results
- Understand fees: Annuities often have high fees. Factor in mortality and expense charges, administrative fees, and surrender charges when evaluating returns.
- Consider alternatives: Before buying an annuity, consider if you've maxed out 401ks, IRAs, and other tax-advantaged accounts first.
- Shop around: Annuity rates and terms vary significantly. Compare multiple providers to get the best rates and terms.
- Understand liquidity: Annuities typically have surrender charges for early withdrawals. Ensure you won't need the money before the surrender period ends.
- Consider inflation: Fixed annuities don't adjust for inflation. Consider inflation-adjusted options or use annuities as part of a diversified retirement strategy.
- Compare to other investments: Use our Compound Interest Calculator to compare annuity growth to traditional investment returns.

When should I consider an annuity?
Consider annuities if you want guaranteed retirement income, have maxed out other retirement accounts, or want to protect against outliving your savings. They're less suitable for young investors who need growth and liquidity.
