With just a few inputs, you can clearly see how your investment grows and how much consistent income it can generate over a specific number of years.

What Is a Monthly Annuity?
A monthly annuity is a financial arrangement where you invest a lump sum and receive regular monthly payments over a set period. These payments include:
- A portion of your original investment (principal)
- Interest earned over time
There are two main types of annuities:
- Ordinary Annuity (End of Month Payments)
Payments are made at the end of each month. - Annuity Due (Beginning of Month Payments)
Payments are made at the beginning of each month.
The difference may seem small, but it affects how much you receive monthly. This calculator allows you to compare both options easily.
How to Use the Monthly Annuity Calculator
Using this tool is simple and takes less than a minute. Follow these step-by-step instructions:
Step 1: Enter the Investment Amount
Input the total lump sum you plan to invest.
This is your principal amount — the base money that will generate income.
Example:
- $50,000
- $100,000
- $250,000
Step 2: Enter the Annual Interest Rate (%)
Add the expected annual return rate offered by your financial institution or investment product.
For example:
- 4%

Make sure this matches your actual investment projection for accurate results.
Step 3: Enter the Number of Years
Specify how long you want to receive payments.
Common examples:

Longer durations reduce monthly payments but increase total payout spread.

If you're unsure, check your financial agreement or consult your advisor.
