Immediate vs Deferred Annuity: What's the Difference?

Core difference in one sentence

An immediate annuity is typically funded with a lump sum and begins income payments within a short period—often within one payment period.

A deferred annuity delays income to a future date while the contract remains in an accumulation phase with defined crediting or growth rules.

If you are still comparing product categories, start with what a fixed annuity is and how fixed annuities work.

Practical example

Retiree A, age 67, wants $2,800/month starting next month and rolls $400,000 into an immediate income annuity with a joint-life election.

Retiree B, age 58, wants income starting at 65 and places $250,000 in a deferred fixed annuity today to crediting growth until a chosen payout date.

Same product family, different jobs: Retiree A optimizes current cash flow; Retiree B optimizes accumulation time and future income start flexibility—subject to surrender rules until payout phase.

Who this may fit

• Retirees who need predictable monthly income starting now (immediate structure)
• Pre-retirees several years from income start who want tax-deferred growth first (deferred structure)
• Households covering essential expenses and comparing <a href="/annuities/fixed-annuity-vs-cd">fixed annuity vs CD</a> alongside annuity timing options
• People bridging to Social Security who model scenarios with <a href="/retirement-income/how-long-will-500k-last">how long $500K may last</a> and the <a href="/tools/retirement-income-calculator">retirement income calculator</a>

Who this may not fit

• Savers who may need full lump-sum access for unknown future costs—surrender and payout rules can limit flexibility
• Investors whose primary goal is maximum long-term equity growth
• People who have not modeled essential vs discretionary spending using the <a href="/tools/retirement-income-calculator">retirement income calculator</a>

Common mistakes

• Buying deferred contracts but expecting immediate-checkbook liquidity without reading surrender schedules
• Annuitizing too early without comparing {_link(_W1 + '/fixed-annuity-rates', 'fixed annuity rates')} and payout quotes
• Ignoring inflation impact on fixed payout amounts over 20+ years
• Assuming deferred always beats immediate because of growth—timing and fees matter
• Skipping comparison with non-annuity income tools in {_link(_RI + '/retirement-income-planning', 'retirement income planning')}
