Retirement Readiness Status
—
Your output cards will change tone based on whether your plan is on track, close, or materially short.
Estimated Retirement Corpus Required
—
This is the target corpus implied by your assumptions.
Projected Corpus at Retirement
—
This shows what your current plan may build by retirement.
Estimated Gap or Surplus
—
Gap means shortfall. Surplus means your projected corpus exceeds the target.
Suggested Change in Monthly Investment
—
The extra monthly amount needed if all other assumptions stay the same.
The retirement corpus shown follows a capital-preserving approach, meaning withdrawals are structured so the capital is intended to last indefinitely rather than being fully exhausted over a fixed retirement period.
All results are estimates based on the assumptions you provide. Actual outcomes will vary with market performance, inflation, and changes in income or expenses.
How This Retirement Planning Calculator Works: The Math Behind It
This calculator uses a structured, clarity-first approach to check whether your current savings and monthly investments are likely to support your retirement lifestyle. It does not stop at a target number. It compares what you may need at retirement with what your current plan is projected to build.
You will see four steps: future expense inflation, required retirement corpus, projected corpus from current savings plus monthly investing, and the final shortfall or surplus. The worked example below uses the same assumptions consistently across all four steps.
Retirement planning begins by inflating your current lifestyle cost to the age at which you plan to retire.
Future Monthly Expense = Current Monthly Expense × (1 + Inflation Rate)Years to Retirement
- Current age: 35
- Retirement age: 60
- Years to retirement: 25
- Current monthly expense: ₹80,000
- Inflation: 6% per year
- ₹80,000 × (1.06)25 = ₹80,000 × 4.29 = ₹3,43,200 per month
The tool uses a capital-preserving approach, where the corpus is intended to support expenses through real return rather than being fully exhausted over a fixed period.
Required Corpus = Annual Expenses at Retirement ÷ (Post-Retirement Return % − Inflation %)
- Future monthly expense: ₹3,43,200
- Annual expenses at retirement: ₹3,43,200 × 12 = ₹41,18,400
- Post-retirement return: 8%
- Inflation during retirement: 6%
- Real return: 2%
- ₹41,18,400 ÷ 0.02 = ₹20,59,20,000 or ₹20.59 crore
The final retirement corpus is built from two moving parts: your existing savings and your continuing monthly investments.
Projected Corpus = Current Savings × (1 + Annual Return)Years
+ Monthly SIP × [((1 + Monthly Rate)Total Months − 1) ÷ Monthly Rate]
- Current retirement savings: ₹25,00,000
- Monthly investment: ₹30,000
- Pre-retirement return: 11% per year
- Monthly rate: 0.917%
- Total months: 300
- From current savings: ₹25,00,000 × (1.11)25 = ₹3,39,50,000
- From SIPs: ₹30,000 × [((1.00917)300 − 1) ÷ 0.00917] = ₹4,72,80,000
- Total projected corpus = ₹8,12,30,000 or ₹8.12 crore
Once the required corpus and projected corpus are known, the calculator shows whether you are on track and what adjustment may be needed.
Gap or Surplus = Required Corpus − Projected Corpus
- Required corpus: ₹20.59 crore
- Projected corpus: ₹8.12 crore
- Shortfall: ₹20.59 crore − ₹8.12 crore = ₹12.47 crore
- Approximate monthly investment increase needed: ₹79,200
Conservative assumptions make the output more decision-useful
Retirement plans usually fail not because the math is difficult, but because inflation is understated, returns are overstated, or investing discipline is assumed rather than maintained. Using grounded assumptions gives a more realistic picture of readiness and makes the suggested change in monthly investment more useful in practice.
Important: These outputs are directional planning estimates. Real outcomes will vary with inflation, return sequence, contribution consistency, tax changes, and post-retirement asset allocation.
India’s CPI inflation averaged approximately 5.5% over the past decade (RBI data).
Nifty 50 has delivered approximately 12–13% CAGR over 20 years (NSE India).
A reasonable long-term planning rate for India when you want your retirement estimate to stay conservative.
Slightly below long-term headline equity returns, helping account for diversification and real-world frictions.
Reflects a more conservative mix in retirement, where preservation and dependable income matter more.
The most useful output is not just the target corpus, but the gap between what you may need and what your current plan may build.
Retirement Planning Example: IIM Graduate, Age 35
Summary: Rajesh, a 35-year-old consulting professional earning ₹28 lakh per year, has ₹18 lakh in EPF, contributes ₹28,000 monthly to EPF, and invests an additional ₹40,000 per month in equity mutual funds. With current monthly expenses of ₹1.2 lakh and an early retirement goal of age 55, the calculator estimates a required retirement corpus of ₹23.1 crore and a projected corpus of ₹6.4 crore, leaving a gap of ₹16.7 crore. To close this gap, he needs to increase monthly SIPs by about ₹2,20,140 or delay retirement to age 60.
Rajesh, 35, consulting professional
Rajesh earns ₹28 lakh per year, already has ₹18 lakh in EPF, contributes ₹28,000 per month to EPF with employer support, and invests another ₹40,000 monthly in equity mutual funds. His current household spending is ₹1.2 lakh per month, and his goal is early retirement at age 55.
- Current age: 35
- Retirement age: 55
- Current retirement savings: ₹18 lakh
- Monthly expenses in retirement: ₹1.2 lakh
- Monthly investment: ₹68,000 (₹28,000 EPF + ₹40,000 SIP)
- Inflation: 6%
- Pre-retirement return: 10%
- Post-retirement return: 8%
- Required Corpus
- ₹23.1 crore
- Projected Corpus
- ₹6.4 crore
- Gap
- ₹16.7 crore
- Monthly Change Needed
- ₹2,20,140
What this result means
Rajesh’s current plan does not fully support retirement at age 55 under these assumptions. The calculator shows that he may need ₹23.1 crore by retirement, but his current EPF balance and monthly investing pattern are projected to build only about ₹6.4 crore. That leaves a shortfall of approximately ₹16.7 crore.
Option 1: Increase monthly SIP
Increase monthly investing by roughly ₹2,20,140 to improve the probability of reaching the target by age 55.
Option 2: Delay retirement
Extend retirement from 55 to 60 to allow more compounding time and reduce pressure on monthly savings.
This worked example is for illustration. Actual outcomes depend on real returns, inflation, contribution consistency, and retirement spending.
Understanding Your Results
The calculator does not only estimate a target corpus. It helps you interpret whether your current plan appears sufficient, where the gap lies, and which levers can move you closer to retirement readiness.
Start with your readiness status, then review the required corpus, projected corpus, gap or surplus, and the suggested monthly investment change. Read the five outputs together, not in isolation.
On Track
Your current savings and monthly investments appear sufficient. Under your assumptions, you are projected to have enough, or more than enough, by retirement.
- Projected corpus is equal to or above required corpus
- Your plan currently looks financially sustainable
- You may have flexibility to retire earlier or preserve extra margin
Needs Attention
You are reasonably close, but there is still a meaningful gap. A moderate course correction today can materially improve long-term readiness.
- You may need to increase monthly savings by around 10 to 30%
- Or extend working years by roughly 2 to 3 years
- This is often fixable with disciplined adjustment, not drastic change
Not on Track
There is a significant shortfall between what your current plan may build and what retirement may require. Timely action matters.
- Increase monthly investments materially
- Review expected retirement expenses more conservatively
- Consider delaying retirement if needed
Estimated Retirement Corpus Required
This is the total amount you may need on the day you retire. It is calculated to support your lifestyle through retirement while keeping the principal largely intact under a capital-preserving approach.
Example: If the result shows ₹20.6 crore, that corpus invested at 8% post-retirement return can generate roughly ₹1.65 crore per year, which helps support about ₹3.4 lakh monthly expenses after accounting for 6% inflation on those expenses each year.
Projected Corpus at Retirement
This is what your current retirement savings plus continuing monthly investments are expected to grow into by your retirement age, based on the pre-retirement return you entered.
Example: If you are 35, already have ₹25 lakh, and invest ₹30,000 monthly at 11% return for 25 years, your projected corpus is approximately ₹8.12 crore.
Estimated Gap or Surplus
This is the difference between what retirement may require and what your current plan may build.
Gap: you are projected to have less than you need, and the amount shows how short you may fall.
Surplus: you are projected to have more than you need, giving you flexibility to retire earlier, spend more comfortably, or preserve a greater safety margin.
Suggested Change in Monthly Investment
If there is a gap, this shows the approximate extra monthly amount you may need to invest to get back on track, assuming retirement age, expenses, and return assumptions stay unchanged.
Example: For a ₹12.47 crore gap over 25 years at 11% returns, the required monthly SIP increase is approximately ₹79,200.
How This Calculator Is Different From a Retirement Corpus Calculator
Retirement planning vs retirement corpus calculation
A retirement corpus calculator typically answers the question:
A retirement planning calculator goes one step further.
It answers:
This calculator focuses on readiness and planning adequacy, not optimisation tactics or aggressive assumptions. It is meant to highlight gaps early, when corrective action is still possible.
These projections are best interpreted within a broader investment philosophy that emphasises disciplined decision-making, long-term thinking, and awareness of risk across life stages.
Assumptions Used in This Retirement Planning Calculator
Key assumptions behind the calculations
This retirement planning calculator uses long-term financial assumptions to keep results realistic and comparable.
INFLATION
Inflation reflects the long-term increase in living costs
PRE-RETIREMENT RETURNS
Pre-retirement returns assume growth-oriented investing
POST-RETIREMENT RETURNS
Post-retirement returns assume a more conservative approach
STEADY INVESTING
Calculations are based on steady investing, without tactical changes
Common Retirement Planning Gaps This Calculator Reveals
What this calculator often highlights
In practice, retirement planning gaps usually arise due to:
Underestimating future living expenses
Starting retirement investments later than ideal
Relying on optimistic return assumptions
Not reviewing retirement plans as income changes
This calculator helps surface these issues early, when adjustments are easier to implement.
When a Calculator Is Not Enough
Limits of a retirement planning calculator
While a retirement planning calculator provides useful estimates, it cannot account for:
- Tax efficiency of withdrawals
- Asset allocation changes over time
- Health care and longevity risks
- Multiple retirement income sources
- Behavioural responses during market volatility
These factors require structured financial planning and periodic review.
