How This Annuity Calculator Works
This calculator models the accumulation phase of a deferred annuity. It starts with your principal, adds regular contributions, applies a periodic net growth rate, subtracts estimated fees, and repeats the process over the number of years entered.
The contribution timing setting matters. Contributions made at the beginning of each period have more time to compound than contributions made at the end of each period.
Simplified accumulation model
New balance = prior balance + contributions + interest - estimated fees. The calculation repeats period by period.
What This Calculator Does Not Do
It does not quote a guaranteed annuity rate, estimate lifetime income, price riders, calculate taxes, model surrender charges, or compare insurer financial strength. Actual annuity contracts can contain caps, participation rates, spreads, market value adjustments, mortality and expense fees, surrender schedules, and special tax rules.
Practical Examples
Comparing net growth after costs
Change the fee estimate to see how ongoing expenses reduce compounding over time.
Ordinary annuity vs annuity due
Switch contribution timing to compare beginning-of-period and end-of-period contribution assumptions.
When This Calculator Is Useful
- Estimating the accumulation value of a deferred annuity.
- Comparing annual versus monthly additions.
- Testing conservative, moderate, and optimistic growth assumptions.
- Understanding how fees can reduce long-term compounding.
- Preparing questions before reviewing an insurer illustration.
Important Limitations
Annuities are contracts, and contract terms matter. This calculator uses simplified math and does not replace the prospectus, policy documents, disclosure forms, tax advice, or insurer-provided illustrations. Variable annuities involve investment risk; fixed and indexed annuities may include guarantees, caps, and restrictions that are not modeled here.

Annuity Calculator FAQ
What does this annuity calculator estimate?
It estimates the accumulation value of a deferred annuity using starting principal, regular additions, growth rate, fees, contribution timing, and the number of years entered.
Is this an annuity payout calculator?
No. This page focuses on the accumulation phase. It does not quote guaranteed lifetime income or an insurer-specific payout rate.
What is the difference between ordinary annuity and annuity due?
An ordinary annuity assumes contributions are made at the end of each period. An annuity due assumes contributions are made at the beginning, giving each contribution one extra period to grow.
Does this calculator include annuity fees?
Yes, it includes an optional annual fee assumption. Real contracts may include surrender charges, rider fees, mortality and expense charges, fund expenses, and administrative costs.
Does this calculator guarantee an annuity return?
No. The growth rate is an assumption. Actual annuity crediting rates, investment returns, caps, participation rates, fees, and guarantees depend on the contract and insurer.
Are annuity withdrawals taxed?
Annuity tax treatment can be complex. This calculator does not estimate ordinary income tax, early withdrawal penalties, exclusion ratios, or qualified plan rules.
Why do fees matter in an annuity projection?
Fees reduce the amount left to compound. Even a small annual fee can make a noticeable difference over a long accumulation period.
Can I use this for fixed, variable, or indexed annuities?
You can use it for simplified scenarios, but each type works differently. Fixed, variable, and indexed annuities may have different guarantees, market exposure, fees, caps, and crediting rules.
What should I compare before buying an annuity?
Compare fees, surrender periods, guarantees, insurer strength, liquidity rules, tax treatment, riders, payout options, and whether lower-cost retirement accounts already meet your needs.
Is this annuity calculator financial advice?
No. It is for educational estimates only and does not replace contract documents, insurer illustrations, tax guidance, or advice from a qualified professional.
