The step used in the Basic Annuity Model
The following steps are used to calculate the amount of money required to fund your entire retirement along with how much you need to save per month.
Step 1. Calculate your Wage Replacement Ratio (WRR) today using one of the two methods identified earlier (top-down or budgeting).
Step 2. Determine gross dollar needs based on your WRR.
Step 3. Determine your net dollar requirement by reducing your the results from step 2 by your Social Security benefits and any other savings you currently have.
Step 4. Inflate your net dollar requirement in step 3 to your retirement age by the inflation rate to determine the first annual retirement payment.
Step 5. Calculate the amount of money that will be required to maintain the annual payment requirement in step 4 over the full retirement life expectancy.
Step 6. Calculate the amount of money needed to be invested per year so that the total amount from step 5 is accumulated by retirement age.
