Planning for retirement is one of the most important financial steps in life. Many people look for ways to ensure a steady stream of income that lasts as long as they live. One effective financial product that offers this security is a life annuity. An annuity converts your retirement savings or a lump-sum payment into guaranteed lifetime income.
To help individuals estimate how much they can receive, a Life Annuity Calculator (Annuity for Life Calculator) becomes an essential tool. It helps calculate the monthly or yearly income you’ll receive based on the amount you invest, your age, expected interest rate, and life expectancy.

How the Annuity for Life Calculator Works
An annuity is essentially a financial contract with an insurance company. You pay a lump sum (or multiple contributions), and in return, you receive regular payments for life. The calculator simplifies the estimation by using:
- Principal Amount (P): The initial investment or lump sum you contribute.
- Interest Rate (r): The assumed annual return on the annuity.
- Payment Frequency (n): Monthly, quarterly, or yearly payments.
- Expected Lifespan (t): The estimated number of years you will receive payments.
The calculator then shows you the annuity payment amount you can expect to receive regularly for life.
Formula Used in Annuity for Life Calculator
The formula for calculating annuity payments is derived from the present value of an annuity:
PMT = P × [r / (1 – (1 + r)^(-n×t))]
Where:
- PMT = Payment per period
- P = Principal investment (lump sum)
- r = Interest rate per period
- n = Number of payment periods per year
- t = Number of years of expected payout
For a life annuity, the calculation is based on life expectancy and mortality assumptions, but this formula gives a good estimate.
Example Calculation
Let’s assume:
- You invest $200,000 in a life annuity.
- Interest rate = 4% annually.
- Payments = Monthly (n = 12).
- Expected life expectancy = 25 years.
Step 1: Convert annual interest rate into monthly = 0.04 ÷ 12 = 0.0033.
Step 2: Multiply periods = 25 × 12 = 300.
Step 3: Apply formula:
PMT = 200,000 × [0.0033 / (1 – (1.0033)^(-300))]
PMT ≈ $1,056 per month.
So, the calculator will show you that with $200,000, you could receive around $1,056 every month for 25 years.
