What is a Single Premium Immediate Annuity (SPIA)?

A Single Premium Immediate Annuity (SPIA) is a type of annuity purchased with a one-time lump-sum payment (the premium). In return, the insurance company guarantees periodic payments for a specified period or for the rest of your life.

Key benefits of a SPIA include:

Guaranteed fixed income
Predictable cash flow
Tax-deferred growth (depending on jurisdiction)
Customizable payout options

Using an SPIA calculator allows you to estimate the periodic income and total payout before committing to an investment.

Example Calculation

Let’s go through an example to understand how the calculator works:

Single Premium Amount: $50,000
Annual Interest Rate: 5%
Number of Years: 10
Payments per Year: Monthly

Step 1: Calculate periodic interest rate
Periodic rate = Annual rate / Payments per year = 5% ÷ 12 = 0.4167%

Step 2: Calculate total number of payments
Total payments = Years × Payments per year = 10 × 12 = 120

Step 3: Use annuity formula
Payment = Premium × r ÷ (1 - (1 + r)^-n)
= 50,000 × 0.004167 ÷ (1 - (1 + 0.004167)^-120)
≈ $530.33 per month

Step 4: Calculate total payout
Total payout = Payment × Total payments = $530.33 × 120 ≈ $63,639.60

This example shows that a $50,000 premium at 5% annual interest over 10 years with monthly payouts results in $530.33 per month and a total payout of $63,639.60.
