How to Use the Pension Calculator
You can calculate your retirement pension in just a few simple steps:
- Enter Your Current Age: Helps determine your investment period.
- Select Your Retirement Age: Usually between 55 and 65 years.
- Enter Monthly Contribution: The amount you plan to invest each month toward your pension.
- Add Expected Rate of Return: Generally between 8% to 10% p.a. on your pension fund.
- Enter Expected Annuity Return: Typically 6% to 7% p.a. depending on your annuity deposit plan.
- View Pension Amount: Instantly view your total retirement corpus and estimated monthly pension.
Pension Calculation Formula
The Pension Calculator uses two main formulas:
1. Total Corpus (Future Value of Investment)
FV = P × [(1 + (r/n))(n×t) – 1] / (r/n)
Where:
- FV = Future Value (Total Corpus)
- P = Monthly Contribution
- r = Annual Rate of Return
- n = Number of compounding periods per year (12 for monthly)
- t = Number of years until retirement
2. Estimated Monthly Pension (Post-Retirement Income)
The accumulated corpus is converted into an annuity using this formula:
Pension = Corpus × Annuity Rate
Note: The annuity rate typically ranges between 5% and 7% depending on your pension provider.
Pension Calculation Example
Let’s take an example:
- Age: 30 years
- Retirement Age: 60 years
- Monthly Contribution: ₹5,000
- Rate of Return: 10% p.a.
Using the formula, your estimated corpus at age 60 will be approximately ₹1.14 crore.
If 40% of this corpus is converted into an annuity at 6% per annum, your monthly pension will be around ₹22,800.
Pension Calculation Projection Table
Here’s an approximate projection of how your monthly contributions can grow over time:
| Monthly Investment (₹) | Investment Period (Years) | Expected Return | Corpus at Retirement (₹) | Estimated Monthly Pension (₹) |
|---|---|---|---|---|
| 2,000 | 20 | 10% | 15.3 lakh | 3,000 |
| 5,000 | 30 | 10% | 1.14 crore | 22,800 |
| 10,000 | 25 | 9% | 98.7 lakh | 19,500 |
| 15,000 | 35 | 10% | 3.84 crore | 76,800 |
