Guaranteed Income Annuity Calculator

Estimate guaranteed lifetime income from a SPIA, DIA, or QLAC. Compare all three types side by side — monthly payouts, break-even ages, and QLAC RMD savings.

Currently optimized for U.S. retirement planning. Support for additional countries is planned.
SPIA — Single Premium Immediate Annuity. You hand the insurer a lump sum and income starts immediately, typically within 30 days. Best for covering essential expenses right now.

Affects life expectancy used in payout rate.

Disclaimer: Payout rates are estimates based on approximate mid-2025 market conditions for life-only annuities with no refund or joint option. DIA and QLAC income is modeled using a 4.5% annual accumulation rate and SSA 2021 survival probabilities — actual insurer quotes vary by company, state, health classification, and current interest rates. QLAC RMD values use the IRS 2022 Uniform Lifetime Table. Always obtain quotes from multiple licensed insurers before any purchase. For educational purposes only. See our methodology for the full formulas behind these estimates.

Understanding SPIA, DIA & QLAC

SPIA — Income Now

Best for retirees who need income immediately to cover essential expenses. Pays the lowest monthly amount per dollar of premium, but starts right away. No investment risk — the insurer guarantees the payment for life.

DIA — Deferred Income

Best for younger retirees who want to lock in future longevity insurance at a low cost today. A 10–15 year deferral can multiply monthly income 3–5× versus a SPIA for the same premium. Income is deferred, so the money keeps growing.

QLAC — IRA-Based DIA

Best for retirees who don't need their full IRA balance for RMDs and want to reduce taxable income in their 70s. Up to $210,000 is excluded from RMD calculations until income starts (max age 85). All income is taxable as ordinary income when received.

What drives payout rates?

Four factors determine how much income you receive: (1) age — older buyers get more per dollar because fewer payments are expected; (2) gender — males receive more because average life expectancy is shorter; (3) interest rates — higher rates mean more income; (4) deferral length — longer deferral compounds growth and mortality credits, dramatically increasing the monthly payment.
