Steps to use a pension Calculator
Provided are the steps to calculate the pension using a pension calculator:
Step 1: Provide your present age in years.
Step 2: Next, provide your monthly expenditure depending on the costs incurred previously & your desired lifestyle.
Step 3: Provide the desired age at which you want to retire.
Step 4: Click “Calculate” to ascertain the estimated monthly expenditures post-retirement along with the desired pension amount.
Step 5: Assess the annual percentage increase in expenditures.
Step 6: Check for the outcomes & make necessary adjustments if required.
Let us understand with the help of an example, Mr X, 30 years have current monthly expenses of INR 50,000. His retirement age is 60 years, with an annual 2% increase in expenses.
The mathematical formula to calculate a pension is:
- First we need to calculate future value of expenses & savings
FV = PV (1 + r) ^n
Where,
FV = Future Value (Retirement savings goals)
PV = Present Value (Present Savings or Investments)
r = Expected Rate of return or inflation
n = Number of Years until retirement
Because of this 2% annual increase, the monthly expense will rise to INR 90568 at the age of 60 years.
- Factors that affect your pension are annuity rates, annuity options, life expectancy & withdrawal structure. Annuity rate usually ranges between 5 – 7%. So, if Mr X wants to sustain Rs. 90,568 per month, he might need a corpus of Rs. 1.8 – 2 crore.
- If annuity rate is 6%, the annual income will be – Rs. 2 crore x 6% = Rs. 12,00,000 which makes the monthly pension as Rs. 1 lakh
