Deferred Annuity Calculator
Model deferred annuity accumulation and payout phases with full lifecycle visualization.

What Deferred Annuity Calculator does
A deferred annuity calculator models the full lifecycle of a tax-deferred annuity, showing both the accumulation phase (where a lump sum grows without annual taxation) and the payout phase (where withdrawals begin at a chosen future date). Users input an initial investment, a guaranteed interest rate, a deferral period, and a payout period to see how their balance changes over time and what guaranteed income stream they can expect. The output is a financial projection of the annuity's value at the start of payouts and the duration those payments would last, helping retirees assess income security. This particular site's version emphasizes the tax-deferred growth advantage over taxable brokerage accounts, using Diane's scenario to illustrate how sheltering growth from yearly taxation can significantly increase the balance rolling forward each year. It presents the accumulation and payout phases as a continuous timeline, making the long-term impact of different savings strategies and market assumptions visible within a single interface.

Deferred Annuity Calculator FAQ
- What is a deferred annuity and how does it differ from a regular investment account?
- A deferred annuity is a contract where you pay a lump sum upfront, the balance grows tax-deferred until a future date, and payouts begin later. Unlike a taxable brokerage account, interest earned each year is not taxed immediately, allowing the full amount to compound within the contract.
- How is the guaranteed interest rate applied in the calculator?
- The calculator uses the guaranteed rate you input to project the balance growth during the deferral period; the rate remains fixed for the projection, but real-world annuities may offer different rates at the start of the payout phase.
- Can I change the deferral period and payout period to see different outcomes?
- Yes, adjusting the deferral period changes how long the balance grows tax-deferred before payouts start, and modifying the payout period affects the length of the withdrawal schedule; the tool recalculates the projected balance and payment amounts accordingly.
- Does the calculator include inflation or annual fees in its projections?
- No, the tool provides projections based on the inputs provided and does not factor in inflation, annual contract fees, or other costs that may reduce the real value of the annuity over time.
