Frequently Asked Questions

What is the difference between an ordinary annuity and an annuity-due?

An ordinary annuity has payments at the end of each period (most common). An annuity-due has payments at the beginning. The annuity-due produces values about (1+r) higher because each payment earns one extra period of interest.

How do surrender charges work?

Most deferred annuities impose a surrender charge (typically 7-10%) if you withdraw before a specified period ends, usually 5-10 years. The charge usually decreases by 1% per year. Always read the contract to understand the exact schedule before investing.

Are annuity payments taxable?

Inside a qualified retirement account (IRA, 401(k)), all withdrawals are ordinary income. In a non-qualified annuity, only the growth portion is taxable; the original principal comes out tax-free on an exclusion-ratio basis.

Can I outlive an annuity?

A period-certain annuity pays for a fixed number of years regardless of whether you live. A life-only annuity pays as long as you live, no matter how long, making it impossible to outlive. Joint-and-survivor annuities continue payments to a surviving spouse.

How This Calculator Works

This calculator solves three annuity problems using standard time-value-of-money formulas. Future Value answers: how much will my series of payments grow to? It uses FV = PMT × [(1+r)ⁿ − 1] ÷ r. Present Value answers: how much is a stream of future payments worth today? It uses PV = PMT × [1 − (1+r)⁻ⁿ] ÷ r. Payment works backward from a lump sum to find the periodic income it can sustain.

All three assume an ordinary annuity where payments occur at the end of each period. An annuity-due (payments at the beginning) would multiply results by (1+r), producing slightly higher values. The rate per period and number of periods must be in the same time unit - if you pay monthly, use a monthly rate (annual rate ÷ 12) and total months.

Types of Annuities

Immediate annuity: Purchased with a lump sum; income begins within one period. Common for retirees converting savings to guaranteed lifetime income.

Deferred annuity: Contributions accumulate for years before payouts begin. Used during the accumulation phase of retirement planning.

Fixed annuity: Earns a guaranteed interest rate set by the insurance company. Predictable, but exposed to inflation risk over long payout periods.

Variable annuity: Invested in sub-accounts similar to mutual funds; value fluctuates with markets. Higher potential growth but no guarantee.

Indexed annuity: Returns linked to a market index (e.g., S&P 500) with a floor (usually 0%) and a cap. Blends principal protection with upside participation.

Payout vs. Accumulation Annuities

An accumulation annuity grows a nest egg - you make regular payments in and let compound interest do the work (use the Future Value tab). A payout annuity converts an existing lump sum into a stream of income - you are drawing down principal plus earnings (use the Present Value or Payment tab).

The same formulas drive both, but the framing is different. For accumulation, you care about how large the account grows. For payout, you care about how long it lasts or how much monthly income it produces. Many retirees use both: they accumulate in a tax-deferred wrapper for decades, then convert part of the balance to a guaranteed income stream at retirement.

Key Considerations and Risks

Surrender charges: Most deferred annuities impose penalties of 7-10% for early withdrawal, declining over 5-10 years. Read the contract carefully before purchasing.

Inflation risk: A fixed $2,000/month payment loses purchasing power every year. After 20 years at 3% inflation, that payment buys roughly half what it did at purchase.

Mortality & expense fees: Variable annuities charge M&E fees of 1-1.5%/year on top of underlying fund expenses, significantly dragging long-term growth.

Tax treatment: Annuity growth inside a non-qualified account is tax-deferred; withdrawals are taxed as ordinary income, not capital gains rates.

Annuities vs. Other Retirement Income

Social Security provides inflation-adjusted lifetime income - maximize it before buying a commercial annuity. A 401(k) or IRA offers flexibility and lower costs. Annuities add value primarily as longevity insurance: if you are worried about outliving your assets, a lifetime income rider or immediate annuity guarantees you cannot run out of money, no matter how long you live.

A common approach is to cover essential expenses (housing, food, healthcare) with guaranteed income sources like Social Security and annuities, and leave discretionary spending to market-linked accounts. This floor-and-upside structure ensures basic needs are met regardless of market performance.

Tax laws change frequently. Verify current limits at IRS.gov and consult a qualified financial advisor before making retirement decisions.
