SPIA vs DIA: Immediate vs Deferred Income Annuities

Compare Single Premium Immediate Annuities to Deferred Income Annuities. Which provides better retirement income?

By Thomas Richardson|Updated March 20, 2026|Reviewed by Editorial Board|8 min read

A SPIA (Single Premium Immediate Annuity) starts lifetime income payments within 12 months of purchase, while a DIA (Deferred Income Annuity) delays payments to a future date, often years or decades later. SPIAs are best for retirees who need income now; DIAs provide higher future payments due to the deferral period and serve as longevity insurance for late-life income starting at age 80-85.

  • SPIA payments start within 12 months; DIA payments start years or decades in the future
  • DIAs provide higher monthly payments than SPIAs because the insurance company keeps your money longer
  • A QLAC (Qualified Longevity Annuity Contract) is a special DIA funded with IRA money
  • SPIAs are generally irrevocable — you cannot access the lump sum once annuitized

Key Takeaways

  • 1SPIA: Income starts immediately (within 12 months)
  • 2DIA: Income starts at future date (often years/decades later)
  • 3SPIA: Best when you need income now
  • 4DIA: Best for longevity insurance - income starting at 80-85
  • 5Both provide guaranteed lifetime income
  • 6DIA typically provides higher future payments due to deferral
  • 7QLAC is a special DIA that can be funded with IRA money

Income Annuity Basics

Both SPIA and DIA convert a lump sum into guaranteed lifetime income. The difference is timing.

  • **Income annuities**: Exchange lump sum for guaranteed payments
  • **Lifetime income**: Payments continue as long as you live
  • **Irrevocable**: Generally cannot access principal once annuitized
  • **Payout rate**: Based on age, rates, and payment option

SPIA: Single Premium Immediate Annuity

SPIAs begin payments immediately - typically within 30 days to 12 months.

  • **Timing**: Payments start within 12 months
  • **Funding**: Single lump sum payment
  • **Use case**: Need retirement income now
  • **Payout**: Based on current age and interest rates
  • **Common purchase age**: 65-75

SPIA Example

70-year-old invests $250,000. Receives approximately $1,500-1,700/month for life, starting immediately.

DIA: Deferred Income Annuity

DIAs begin payments at a future date, often years or decades later.

  • **Timing**: Payments start at chosen future age (e.g., 80, 85)
  • **Funding**: Single lump sum now
  • **Use case**: Longevity insurance - protect against living very long
  • **Payout**: Higher than SPIA due to deferral period
  • **QLAC**: Special DIA for IRA money, payments can start up to age 85

DIA Example

65-year-old invests $100,000 in DIA starting at 80. Could receive $2,500-3,500/month for life - much higher than SPIA due to 15-year wait.

Frequently Asked Questions

1What if I die before DIA payments start?

Depends on your policy. Some DIAs return premium to beneficiaries, others don't. Cash refund or return of premium options cost more but provide protection.

2Can I change my DIA start date?

Generally no - the start date is set at purchase. Some policies offer limited flexibility. This is why the decision requires careful thought.

3Is QLAC a good idea?

It can be for those worried about outliving their money. It reduces RMDs and provides guaranteed income later. But you give up control of that money.
