What is a Retirement Calculator?
A Retirement Calculator is an online investment planning tool that estimates the retirement corpus you may need to maintain your lifestyle after you stop working. Using your current age, retirement age, monthly expenses, inflation and assumed investment returns (before and after retirement), it projects how much you should accumulate before retirement.
Unlike a basic investment calculator, a Retirement Calculator considers the impact of inflation on your future expenses and estimates whether your existing retirement savings are enough. It also calculates the additional corpus and monthly SIP required to bridge any shortfall.
Whether you're planning for early retirement or building long-term financial security, the calculator helps you set realistic retirement goals, understand your savings gap and make informed investment decisions.
No spam. No cold calls. A conversation to understand your goals.

- 01
Enter Your Current and Retirement Age
Enter your current age and the age at which you plan to retire.
Tip: Retiring earlier usually requires a larger retirement corpus.

Choose Your Life Expectancy
Enter the age until which you expect your retirement corpus to support your expenses.
Tip: A longer life expectancy generally requires a larger retirement corpus.
- 03
Enter Your Current Monthly Expenses
Provide your current monthly living expenses to estimate your future retirement expenses after adjusting for inflation.
Tip: Exclude temporary expenses that won't continue after retirement.
- 04
Add Existing Retirement Savings
Enter the investments you've already set aside for retirement, such as EPF, NPS or mutual funds.
Tip: Include only savings dedicated to your retirement goals.
- 05
Set Inflation and Investment Return Assumptions

Review Your Retirement Plan
The calculator estimates your required retirement corpus, preparedness level, additional corpus and monthly SIP needed to achieve your goal.
Try different retirement ages, inflation rates and investment returns to understand how each factor affects your retirement plan and monthly investment requirement.

How the Retirement Calculator Works
The Retirement Calculator first estimates how your current monthly expenses will increase by your planned retirement age after accounting for inflation. This helps determine the income you'll need to maintain a similar lifestyle after retirement.
It then projects how your existing retirement corpus may grow until retirement using the assumed return before retirement. The calculator also uses the assumed return during retirement to estimate how much corpus is required to sustain your expenses throughout retirement.
Finally, the calculator estimates the monthly SIP needed to bridge the remaining gap before retirement. The results are intended for retirement planning and should be reviewed periodically as your income, expenses and financial goals change.
Future Monthly Expenses
The calculator estimates your monthly expenses at retirement by adjusting your current monthly expenses for inflation over the years until retirement.
Retirement Corpus Required
The calculator estimates the retirement corpus required to fund your inflation-adjusted monthly expenses throughout your retirement years.
Additional Corpus Required
The funding gap is calculated by subtracting the projected value of your existing retirement corpus from the total retirement corpus required.
Monthly SIP Required
The calculator estimates the monthly SIP required before retirement to accumulate the additional retirement corpus needed.
Understanding the Inputs
Current Age
Your current age determines how many years you have to build your retirement corpus. Starting earlier gives your investments more time to benefit from compounding.
Tip: Enter your actual age to get the most accurate retirement projection.
Planned Retirement Age
The age at which you expect to stop working and begin using your retirement savings. It determines your investment timeline and the number of years available to build wealth.
Tip: A later retirement age generally reduces the monthly investment required.
Current Monthly Expenses
Your current monthly living expenses are used to estimate your future retirement expenses after adjusting for inflation. This helps calculate the retirement corpus needed to maintain your lifestyle.
Tip: Exclude temporary expenses that won't continue after retirement.
Existing Retirement Corpus
This includes the savings and investments you've already accumulated specifically for retirement, such as EPF, NPS, PPF and retirement-focused mutual fund investments. The calculator projects how this corpus may grow until your retirement date.
Tip: Include only investments that are specifically intended for retirement.
Assumed Inflation Rate
Inflation estimates how much the cost of living may increase over time. A higher inflation rate means you'll need a larger retirement corpus to maintain the same lifestyle.
Tip: Try different inflation assumptions to understand how changes in future living costs affect your required retirement corpus.
Assumed Return Before Retirement
This is the assumed annual return on your investments before retirement. It is used to estimate how your existing retirement corpus and future SIP investments may grow until your retirement age.
Tip: Use realistic long-term return assumptions instead of overly optimistic projections.
Life Expectancy
Life expectancy determines how long your retirement corpus needs to support your expenses after retirement. A longer retirement period generally requires a larger retirement corpus.
Tip: Choose a realistic life expectancy while accounting for longer life spans and future healthcare needs.
Assumed Return After Retirement
This is the assumed annual return on your retirement investments after you retire. It helps estimate how long your retirement corpus can sustain your monthly withdrawals.
Tip: Retirement portfolios are typically more conservative, so this return is often lower than the assumed return before retirement.

See It in Action
Suppose a 30-year-old professional plans to retire at age 60, expects to live until age 85, spends ₹50,000 per month, already has ₹5,00,000 saved for retirement, and uses an assumed 6% annual inflation rate, an assumed 12% annual investment return before retirement and an assumed 7% annual investment return during retirement.

Results
What this means: Starting retirement planning at age 30 gives your investments three decades to compound. Beginning early can significantly reduce the monthly SIP required because your investments have more time to compound.

Common Mistakes to Avoid
Using the same investment return before and after retirement
Investment strategies often become more conservative after retirement. Assuming identical returns throughout retirement may underestimate the corpus required.
Starting retirement planning too late
Delaying retirement planning reduces the time available for compounding and usually requires much larger monthly investments to achieve the same retirement corpus.
Ignoring inflation
Future living costs are likely to be much higher than today's expenses. Ignoring inflation can lead to a retirement corpus that falls short of your actual financial needs.
Using unrealistic return assumptions
Assuming very high investment returns may underestimate the savings required. Testing different return assumptions can provide a more balanced view of the retirement requirement.
Not reviewing your retirement plan
Income, expenses, inflation and financial goals change over time. Reviewing your retirement plan regularly helps keep your investments aligned with your long-term objectives.
Ignoring existing retirement investments
Excluding investments such as EPF, NPS or retirement-focused mutual funds can give an inaccurate picture of your retirement preparedness.
Underestimating healthcare expenses
Medical expenses often increase with age. Including healthcare costs in your retirement planning can help protect your retirement corpus from unexpected financial stress.

Start Retirement Planning Early vs Start Late
Time is one of the most important factors in retirement planning. Starting early gives your investments longer to compound, reducing the monthly investment required to build your retirement corpus.
Starting retirement planning early allows your investments to benefit from compounding for longer, helping you build a larger retirement corpus with smaller monthly investments. Delaying retirement planning often increases the savings required to achieve the same financial goal.
