Retirement Income Stream
Last reviewed: May 2026
Annuities convert a lump sum into a predictable income stream, transferring longevity risk from you to an insurance company.[1] They are the only financial product that can guarantee income you cannot outlive. This calculator models both the accumulation phase (growing your money) and the payout phase (converting to income). Compare with other retirement tools: Retirement Calculator and Social Security Calculator.
| Type | Return | Risk | Fees | Best For |
|---|---|---|---|---|
| Fixed | 4–6% guaranteed | Very low | 0–0.5% | Conservative, guaranteed income |
| Fixed indexed | 2–8% (capped) | Low | 0.5–1.5% | Growth potential with floor |
| Variable | Market-based | Medium-High | 2–3% | Growth-oriented, long horizon |
| SPIA (immediate) | Payout-based | None (guaranteed) | Built into payout | Immediate retirement income |
During the accumulation phase, your annuity grows tax-deferred — no annual taxes on interest, dividends, or capital gains until you begin withdrawals. This tax deferral accelerates compound growth compared to a taxable account earning the same rate. A $100,000 investment at 5% for 20 years grows to $265,330 tax-deferred versus approximately $219,000 in a taxable account (assuming a 24% bracket and annual taxation of gains). The longer the accumulation period, the more valuable tax deferral becomes. However, unlike 401(k)s and IRAs, annuity contributions are not tax-deductible (for non-qualified annuities), so the benefit is purely tax deferral on growth rather than a tax deduction on contributions. Use our Compound Interest Calculator to model tax-deferred versus taxable growth side by side.
| Lump Sum | Age at Start | Monthly Payout (Life Only) | Annual Income | Break-Even Age |
|---|---|---|---|---|
| $100,000 | 60 | $490–$540 | $5,880–$6,480 | 76–78 |
| $100,000 | 65 | $550–$620 | $6,600–$7,440 | 78–80 |
| $250,000 | 65 | $1,375–$1,550 | $16,500–$18,600 | 78–80 |
| $500,000 | 70 | $3,100–$3,500 | $37,200–$42,000 | 82–84 |
| $100,000 | 70 | $620–$700 | $7,440–$8,400 | 82–84 |
Break-even age represents when your total payouts exceed your initial investment. Life-only annuities pay the highest monthly amount because payments stop at death with no residual value to heirs. Adding a 10-year certain period (guaranteeing at least 10 years of payments to your beneficiary) reduces the monthly payout by approximately 5–10%. Adding a joint-life survivor benefit (payments continue to a spouse) reduces the monthly payout by 15–25% depending on the spouse's age.
Most deferred annuities impose surrender charges during an initial period — typically 5 to 10 years — that penalize early withdrawals. A common schedule starts at 7% in year one and decreases by 1% annually, reaching zero in year eight. On a $200,000 annuity, withdrawing in year one costs $14,000 in surrender charges alone. Most contracts allow penalty-free withdrawals of up to 10% of the account value per year, providing some liquidity within the surrender period. Additionally, withdrawals before age 59½ incur a 10% IRS early withdrawal penalty on the earnings portion, on top of ordinary income taxes. This double penalty structure makes annuities unsuitable for money you might need before retirement. The critical planning principle: only commit money to an annuity that you are confident you will not need for at least the full surrender period.
Fixed indexed annuities (FIAs) represent a middle ground between fixed and variable types. Your return is linked to a market index — typically the S&P 500 — but with a guaranteed floor (usually 0–1%) that protects against losses. The trade-off is a cap or participation rate that limits your upside. With a 6% cap, if the S&P 500 returns 20%, you earn 6%. If it returns 4%, you earn 4%. If it returns -15%, you earn 0% (the floor). Over a 10-year period, an FIA might average 4–6% annually compared to the S&P 500's historical average of roughly 10%. The appeal is psychological as much as financial: FIA holders never see a negative annual return on their statement, which prevents the panic selling that destroys many investors' returns during market downturns.
| Fee Type | Fixed Annuity | Fixed Indexed | Variable |
|---|---|---|---|
| Mortality & expense | 0% | 0–0.5% | 1.0–1.5% |
| Administrative | 0% | 0–0.15% | 0.1–0.3% |
| Investment management | N/A | N/A | 0.5–1.5% |
| Rider charges (GLWB, etc.) | 0% | 0.5–1.5% | 0.5–1.5% |
| Total annual cost | 0–0.5% | 0.5–2.0% | 2.0–4.0% |
Variable annuity fees are the highest in the financial product industry. A variable annuity charging 3% annually needs to earn 3% just to break even — before inflation. Over 20 years, 3% annual fees consume roughly 45% of potential portfolio growth. Fixed annuities have the lowest costs because the insurance company invests conservatively in bonds and retains the spread between its investment return and the guaranteed rate it pays you. Before purchasing any annuity, request the total fee disclosure and compare the net return (after all fees) against alternative retirement income strategies including systematic portfolio withdrawals.
Annuities solve one problem that no other financial product addresses: guaranteed lifetime income regardless of market conditions or how long you live. The optimal use case is allocating a portion of retirement savings — typically enough to cover essential expenses (housing, food, utilities, insurance) minus Social Security — to a fixed or immediate annuity. This creates a "floor" of guaranteed income that covers necessities, while the remaining portfolio is invested for growth, discretionary spending, and legacy goals. A retiree with $800,000 in savings and $2,000 per month in Social Security who needs $4,500 monthly for essentials might allocate $300,000 to an immediate annuity generating $1,800 per month, creating a combined guaranteed floor of $3,800. The remaining $500,000 stays invested for growth and flexibility. This approach eliminates the fear of running out of money for basic needs while preserving investment upside for the rest.

Optional riders add features to base annuity contracts — for an additional annual fee (typically 0.5–1.5% of the account value). The Guaranteed Lifetime Withdrawal Benefit (GLWB) is the most popular, guaranteeing a minimum withdrawal percentage (usually 4–5%) for life regardless of account performance. This means even if the underlying investments decline to zero, the insurance company continues paying the guaranteed amount. Death benefit riders ensure heirs receive at least the original premium if the annuitant dies during the accumulation phase, protecting against market losses erasing the initial investment. Income doublers increase payouts if the annuitant enters a nursing home or requires long-term care, combining annuity and insurance functions. Each rider adds cost that reduces net returns — evaluate whether the guarantee addresses a genuine risk in your plan or simply provides expensive peace of mind that could be achieved more cheaply through other means.
The fundamental alternative to annuitizing is the systematic withdrawal approach: investing in a diversified portfolio and withdrawing a fixed percentage (commonly 4%) annually, adjusting for inflation. Historical backtesting suggests a 4% initial withdrawal rate from a 60/40 stock-bond portfolio has survived every 30-year period in US market history — but past performance does not guarantee future results, and the 4% rule provides no contractual guarantee. The annuity advantage is certainty: regardless of market crashes, inflation spikes, or living to age 105, payments continue. The portfolio advantage is flexibility, growth potential, and legacy: unspent assets pass to heirs, withdrawal rates can adjust to market conditions, and long-term equity returns historically exceed annuity payouts. Many financial planners recommend a hybrid approach — annuitize enough to cover essential expenses and maintain a portfolio for discretionary spending and legacy — which captures the benefits of both strategies.

→ Use annuities for a portion of retirement. They complement, not replace, a diversified portfolio.[1]
→ Compare fees carefully. Variable annuity fees can erode 2-3% of returns annually.[2]
→ Watch surrender charges. Most annuities lock your money for 5-10 years with penalties for early withdrawal.
→ Consider a SPIA for simplicity. Single premium immediate annuities have the lowest fees and most straightforward structure.
