When Will My Retirement Money Run Out Calculator

Retirement planning is a critical financial decision that requires careful consideration. One of the most important questions to answer is: When will my retirement savings run out? This calculator helps you estimate the timeline based on your current savings, expected withdrawals, and investment returns.

How to Use This Calculator

Using this retirement money calculator is simple. Follow these steps:

Enter your current retirement savings amount in the "Current Savings" field.
Specify your annual withdrawal amount in the "Annual Withdrawal" field.
Input your expected annual investment return percentage in the "Annual Return" field.
Click the "Calculate" button to see when your money will run out.

The calculator will display the estimated year your savings will be depleted based on your inputs. Remember that this is an estimate and actual results may vary.

Formula Used

The calculator uses the following formula to estimate when your retirement money will run out:

Years Until Depletion = log(Annual Withdrawal / (Annual Withdrawal - Current Savings × Annual Return)) / log(1 + Annual Return)

Where:

Current Savings = Your current retirement savings amount
Annual Withdrawal = The amount you plan to withdraw each year
Annual Return = Your expected annual investment return (expressed as a decimal)

This formula assumes your savings grow at the specified annual return rate while you make annual withdrawals.

Worked Example

Let's look at an example to understand how the calculator works. Suppose you have:

Current Savings = $500,000
Annual Withdrawal = $40,000
Annual Return = 4% (or 0.04)

Using the formula:

Years Until Depletion = log(40000 / (40000 - 500000 × 0.04)) / log(1 + 0.04) Years Until Depletion = log(40000 / (40000 - 20000)) / log(1.04) Years Until Depletion = log(40000 / 20000) / log(1.04) Years Until Depletion = log(2) / log(1.04) Years Until Depletion ≈ 10.5 years

This means your $500,000 savings at a 4% annual return would be depleted in approximately 10.5 years if you withdraw $40,000 each year.
