Retirement Savings Calculator
Calculate how much you need to save for retirement and whether you are on track.
About this calculator
The Retirement Savings Calculator answers a practical question: given what you already have, how much more do you need to save each month to retire on time? It inflates your expenses to retirement, calculates the corpus that will last the retirement years, subtracts the future value of your current savings and divides the rest into a monthly amount.
Here you set the retirement duration directly, so you can test plans for 20, 25 or 30 years of retirement. The summary shows years to retirement, future monthly expenses, the corpus required, the future value of your current savings and the monthly SIP needed.
How to use it
- Enter your Current Age and Retirement Age.
- Enter your Current Monthly Expenses.
- Set the Expected Annual Return and Expected Inflation Rate.
- Enter the Retirement Duration in years and your Current Savings.
- Press Calculate and read the summary.
Method
Future expenses: Spend × (1 + inflation)years. Corpus required: the present value of an inflation-growing annual withdrawal for the retirement duration at the real rate (return − inflation) ÷ (1 + inflation). Savings grow at the return rate. The SIP is Gap × i ÷ ((1 + i)n − 1) with i the monthly return.
Worked example
Age 30, retire at 60, spend ₹50,000, 10% return, 6% inflation, 25 years of retirement, ₹2,00,000 saved
| Monthly expenses at 60 | ₹2,87,175 |
| Corpus required | ₹5,51,47,006 |
| Current savings grow to | ₹34,89,880 |
| Gap | ₹5,16,57,126 |
| Monthly SIP needed | ₹22,852 |
Your ₹2 lakh of savings grows to ₹34.9 lakh by 60. It covers only 6% of the target, so almost all the work falls to regular saving.
Tips and common mistakes
- Longer retirement means a larger corpus. Each extra five years adds roughly 10 to 12% to the target.
- Delaying the start of saving by five years raises the monthly SIP sharply.
- Test a lower return. If the plan only works at 12%, it is fragile.
- Increase the SIP every year with your salary using the step-up SIP calculator.
- Treat the output as a planning guide, not a promise.
Frequently asked questions
How is this different from the Retirement Calculator?
This one lets you set the retirement duration directly instead of using a life expectancy age, and it assumes the same return before and after retirement.
What retirement duration should I use?
If you retire at 60, 25 to 30 years is prudent.
Why does the future expense look so high?
Inflation compounds over decades. At 6%, ₹50,000 becomes about ₹2.87 lakh in 30 years.
What if I cannot afford the SIP shown?
Extend the working years, reduce expenses, accept a lower retirement lifestyle or increase the SIP gradually.
Does it consider EPF and PPF?
Add those balances to current savings.
Is the result guaranteed?
No. It depends on the return and inflation you assume.
