Annuity Monthly Payment Calculator
Whether you’re planning your retirement, evaluating an investment, or managing your finances, understanding annuity payments is essential. Our Annuity Payment Calculator helps you determine your expected monthly payments from a lump sum investment over a specific number of years at a fixed interest rate.
This tool is especially useful for anyone dealing with structured settlements, retirement funds, lottery payouts, or financial planning scenarios. It eliminates complex math by giving you instant, accurate results with just a few simple inputs.
What Does the Annuity Payment Calculator Do?
An annuity is a financial product that pays out a fixed stream of payments to an individual, typically used as an income stream during retirement. The calculator helps you answer the question:
“If I invest a certain amount of money now, how much will I receive each month over X years at Y interest rate?”
Using your inputs, it applies a standard annuity payment formula:
PMT = PV × [r / (1 – (1 + r)^-n)]
Where:
- PMT = monthly payment
- PV = present value (initial investment)
- r = monthly interest rate
- n = total number of months
The tool supports cases where the interest rate is zero, simplifying calculations for zero-growth or fixed-term payout plans.
How to Use the Annuity Calculator – Step-by-Step
Using the calculator is simple. Here’s a detailed breakdown:
1. Enter the Present Value ($)
This is your initial investment or the current value of the lump sum you plan to convert into monthly payments.
Example: If you invest $100,000 into an annuity, enter 100000.
2. Enter the Annual Interest Rate (%)
Input the expected fixed annual return on your annuity. This should be the net rate after fees.
Example: If your annuity earns 5% per year, enter 5.
3. Enter the Number of Years
Specify the number of years over which you want to receive payments.
Example: If you want payouts over 20 years, enter 20.
4. Click “Calculate”
Press the Calculate button to generate your estimated monthly payment.
5. View the Results
The tool displays your monthly payment based on the data you entered.
6. Click “Reset” (optional)
Clear the form to try a new scenario or recalculate with different numbers.
Example: Annuity Payment Scenario
Let’s say you invest $150,000 into an annuity with a 4% annual interest rate for a term of 15 years.
Here’s how it calculates:
- Monthly Rate: 0.04 / 12 = 0.003333
- Total Months: 15 × 12 = 180
- Payment:
PMT = 150,000 × [0.003333 / (1 - (1 + 0.003333)^-180)]
= $1,109.57
So, you would receive about $1,109.57 every month for 15 years.

15+ Detailed Frequently Asked Questions (FAQs)
1. What is an annuity?
An annuity is a contract that pays out a fixed stream of payments over time in exchange for an initial investment, typically used for retirement income.
2. How does this calculator work?
It uses the present value, annual interest rate, and number of years to compute a fixed monthly payment using the annuity formula.
3. What is the present value in this context?
It’s the lump sum of money you invest upfront in exchange for regular payouts.
4. What happens if I set the interest rate to 0%?
The calculator will divide your initial investment evenly across the total number of months, assuming no growth.
5. Does this tool account for inflation?
No. It assumes a fixed interest rate and does not adjust payments for inflation.
6. Can I use this calculator for retirement planning?
Absolutely. It’s a great way to model monthly income from retirement savings over a fixed period.
7. Is the monthly payment taxable?
That depends on your jurisdiction and annuity type. Typically, a portion may be taxable if funded with pre-tax dollars.
8. Can I change the frequency of payouts?
This calculator only supports monthly payouts. For quarterly or annual options, use a dedicated annuity calculator.
9. Does this work for variable annuities?
No. It assumes a fixed interest rate. Variable annuities require more complex modeling due to fluctuating returns.
10. What if I withdraw early?
Early withdrawal may result in penalties or altered payment structures. This calculator assumes full-term commitment.
11. How accurate is this estimate?
It’s mathematically precise, assuming inputs are accurate and there are no hidden fees or taxes.
12. Can this be used for loan amortization?
Not directly. Loan amortization includes debt interest and principal payments, whereas annuity payments come from your investment.
13. Is compound interest used in the calculation?
Yes, the monthly rate assumes compounding to accurately reflect interest over time.
14. What is the difference between present value and future value?
Present value is today’s investment; future value is what it will grow to. This calculator focuses on present value and monthly income.
15. Is this suitable for structured settlement payouts?
Yes. It provides a helpful estimate for converting lump sums into equal monthly payments over a fixed term.
16. How do I adjust for taxes and fees?
You can reduce the interest rate slightly or the present value to simulate post-tax, post-fee outcomes.
17. Can this calculator help me compare annuity products?
Yes. Run the numbers for each product’s interest rate and term to see which one offers better monthly returns.
18. Will this calculator work for perpetual annuities?
No. Perpetual annuities require a different formula as they have no fixed end date.
19. Can this be used for reverse annuities?
No. Reverse annuities are structured differently, often including debt accumulation over time.
20. Is it safe to rely solely on annuities for income?
It depends on your financial goals. Many advisors recommend diversifying income sources beyond just annuities.
