A deferred annuity has two distinct phases: an accumulation phase (you contribute and the money grows tax-deferred) followed by a payout phase (you receive regular income). This two-phase structure makes deferred annuities uniquely powerful for younger savers — the accumulation period can last decades before income begins. This calculator handles both phases in one view.
The Power of the Accumulation Phase
The deferred annuity's greatest advantage is time. A 40-year-old depositing $50,000 plus $500/month for 25 years at 5.5% accumulates approximately $410,000 by age 65 — then that balance can generate over $2,700/month for 20 years. Without the deferred structure and tax-deferred growth, the same after-tax contributions in a taxable account would likely accumulate meaningfully less due to annual tax drag on interest and dividends.
Why the Payout Rate Differs from the Accumulation Rate
Insurance companies use different rates for growth and payout. The accumulation rate reflects what they can earn investing your money; the payout rate also factors in mortality experience and administrative costs. Always confirm both rates in your contract. For the payout formula, we use the standard present-value-of-annuity calculation. See our annuity payout calculator for detailed payout-only modeling, or our immediate annuity calculator if you're ready to start income today.
Frequently Asked Questions
What is the difference between a deferred and immediate annuity?
An immediate annuity converts a lump sum into income right away — within 30 days of purchase. A deferred annuity has a waiting period (the accumulation phase) during which your money grows before any income begins. Deferred annuities are better for people who are still working and want to build wealth tax-deferred. Immediate annuities are better for retirees who need income to start right away. Both ultimately serve the same goal: converting savings into a reliable income stream.
How long should I defer an annuity?
The longer you defer, the more you accumulate due to compounding — but delaying income also means you forgo years of payments. A common strategy is to defer until age 65–70 when Social Security benefits are also maximized, creating complementary income streams. Longevity annuities (also called DIA or QLAC) are specifically designed to start income very late (age 80–85), providing insurance against living an exceptionally long life. The IRS allows up to $200,000 in a QLAC within a qualified retirement account.
What happens if I die during the accumulation phase?
Most deferred annuities include a death benefit that pays your named beneficiary at least the account value, or the total of your contributions (whichever is higher), if you die before annuitization. Enhanced death benefits are available for an additional fee and may lock in higher values at market peaks. This is one advantage deferred annuities have over term life insurance: the death benefit is funded by your own contributions rather than being a separate expense.
Can I withdraw money during the accumulation phase?
Yes, but with restrictions. Most contracts allow a free withdrawal of up to 10% of the account value per year without surrender charges. Amounts above this free withdrawal amount trigger surrender charges, typically declining from 7–10% in year one to 0% by the end of the surrender period (usually 5–10 years). Early withdrawals before age 59½ also trigger a 10% IRS penalty plus ordinary income tax on earnings. Plan for this illiquidity when deciding how much to allocate to a deferred annuity.
