Annuity Withdrawal Calculator
Managing your retirement funds effectively is crucial for long-term financial stability. One of the most important questions retirees and pre-retirees face is: How long will my money last if I withdraw a set amount each year? To help answer this, we’ve built a simple yet powerful Annuity Withdrawal Calculator—a free online tool that estimates how long your investment will sustain annual withdrawals based on interest earned.
Whether you’re planning for retirement, managing a trust, or simply exploring long-term investment strategies, this calculator provides a clear picture of how your savings will behave over time.
What Is the Annuity Withdrawal Calculator?
The Annuity Withdrawal Calculator is an online financial tool that simulates how an investment grows (or shrinks) over a set number of years while withdrawing a fixed amount annually. It takes into account your initial investment, annual interest rate, desired yearly withdrawal, and the number of years you wish to project.
The tool then calculates:
- Total amount withdrawn
- Total interest earned
- Ending balance
- Whether or not your funds will last the full term
This can be helpful for retirement planning, educational trusts, or any other scenario where funds are drawn down over time.
How to Use the Annuity Withdrawal Calculator (Step-by-Step)
Using the tool is incredibly simple and doesn’t require any financial expertise. Here’s how to get started:
Step 1: Enter Your Initial Investment
Input the amount you are starting with. This could be your total retirement savings or the principal amount of a trust. Example: $100,000.
Step 2: Input Your Expected Annual Interest Rate
This is the expected return rate on your investment per year. Example: 5%.
Step 3: Specify the Annual Withdrawal Amount
Enter how much money you plan to withdraw each year. Example: $10,000.
Step 4: Choose the Number of Years
Decide over how many years you’d like to simulate the withdrawals. Example: 20 years.
Step 5: Click “Calculate”
Once all fields are filled, click the “Calculate” button. The tool will instantly display:
- Ending balance
- Total interest earned
- Total amount withdrawn
- Status (whether funds last or run out before the selected term)
Click “Reset” to clear all fields and start a new calculation.
