You don't need to pick a random number and hope it's enough. A better approach is to build your retirement goal from your own expenses and financial situation.
Here is a simple way to get started:
1. Calculate Your Current Monthly Expenses
Add up your regular expenses such as groceries, rent, bills, travel, insurance, and other household costs. This gives you a starting point for your retirement calculation.
2. Separate Retirement-Related Expenses
Think about which expenses will continue after you stop working. Some costs may go down, while others may increase. For example, commuting costs may fall, but healthcare and leisure expenses could rise.
3. Estimate Inflation
Your expenses today won't stay the same forever. Use a reasonable inflation assumption to estimate what your current expenses could look like in retirement.
4. Decide Your Retirement Age
Choose the age at which you would ideally like to stop working. This tells you how many years you have to build your retirement savings.
5. Estimate How Long Your Retirement Could Last
Retirement planning doesn't end when you stop working. Your savings may need to support you for 20, 30, or more years, depending on your circumstances.
6. Keep Healthcare and Emergencies in Mind
Set aside money for medical treatment, insurance, unexpected expenses, and other situations that may come up during retirement. These costs can be difficult to predict, so having a separate buffer can help.
7. Add Your Existing Investments
Check what you have already saved through mutual funds, EPF, PPF, fixed deposits, or other investments. These assets can form part of your retirement corpus.
8. Estimate Your Investment Returns
Your expected return can affect how much you need to invest today. Keep your assumptions realistic and remember that market-linked investments do not offer guaranteed returns.
9. Calculate Your Required Retirement Corpus
Now bring everything together: your future expenses, inflation, retirement period, existing savings, expected returns, and other income. This will give you a better estimate of the amount you may need.
10. Review Your Plan Regularly
Your income, expenses, investments, and retirement plans can change. Review your retirement goal from time to time and increase your SIP or other investments as your income grows.
The earlier you start, and the more regularly you review your plan, the easier it can be to stay on track toward your retirement goal.
