Step-by-Step: How Your Money is Projected

Step 1: Net Withdrawal Calculation

We take your Monthly Expenses and subtract any Additional Monthly Income. The difference is your base withdrawal need.

Step 2: Tax Adjustments

Because you need a specific amount in hand to pay expenses, we calculate the gross amount you must withdraw to cover both your expenses and the taxes owed on the withdrawal.

Step 3: Inflation Impact

Each month, your living expenses are increased by the monthly equivalent of your annual inflation rate. This ensures purchasing power remains constant over decades.

Step 4: Investment Growth

Your remaining portfolio balance is compounded monthly based on your expected annual return, generating interest earnings that fight against depletion.

Step 5: The “Safe Withdrawal” Rule

Financial planners often use the “4% Rule”. If your initial annual withdrawal is less than 4% of your starting portfolio, historical data suggests a high probability it will last 30+ years.

Step 6: Emergency Reserve

The Emergency Reserve is sequestered from your starting balance. It does not grow and is not withdrawn from, acting as your ultimate safety net.
