What Is a SPIA (Single Premium Immediate Annuity)?

A SPIA is a type of annuity purchased with a one-time lump sum premium. In return, the insurance company provides guaranteed income payments, typically starting within 30 days to 12 months after purchase.

Key features of a SPIA include:

  • Immediate payouts – Income begins almost right away.
  • Fixed monthly payments – Ensures predictable retirement income.
  • Customization – Choose payout period (fixed years or lifetime).
  • Interest factor – Payments are partly based on interest assumptions.

Why Use a SPIA Annuity Calculator?

Planning retirement without accurate numbers can be stressful. The SPIA calculator removes guesswork by showing:

✅ How much monthly income your premium will generate
✅ The impact of different payout periods
✅ How interest rates affect payments
✅ Your total payout over time

This tool is especially useful when comparing annuity options or deciding whether to allocate part of your retirement savings into a SPIA.

    • This is your lump sum investment (e.g., $100,000).
  2. Enter Payout Period (Years)
    • Choose how long you want payments (e.g., 20 years).
  3. Enter Annual Interest Rate (%)

Example Calculation

Let’s say you invest $100,000 into a SPIA with:

  • Payout Period: 20 years
  • Annual Interest Rate: 3%

👉 The calculator would estimate:

  • Monthly Payment: about $554.60

Tips for Getting the Most Out of the Calculator

Limitations to Keep in Mind

While the calculator is powerful, note that:
