Find out how much you need to save monthly for a comfortable retirement

If you spend ₹50,000/month today and retire at 60, inflation will push that to ₹2.87 lakh/month by then. You need a corpus large enough to sustain 25+ years of retirement. This calculator shows the exact monthly savings needed.

Real-Life Guide to Using the Retirement Planner

Corpus needed for retirement. Use the examples and checks below to turn the number into a practical decision.

When this calculator is useful

Anyone in their 30s to 50s who wants to estimate the total corpus needed by a target retirement age, based on current monthly expenses, expected inflation, and the number of years the corpus must last.

For most people, the best way to use the Retirement Planner is to try the real case first, then change one input at a time. That makes the trade-off visible. For example, with a loan calculator you can change tenure while keeping the same rate; with an investment calculator you can change return assumption while keeping the same monthly contribution; with a health, education or measurement calculator you can check how much one input changes the final category.

The result should answer a practical question: Can I afford this? How much should I save? Is this score enough? Is this measurement within range? What is the safer or cheaper option? If the output does not answer the decision clearly, adjust the inputs until the scenario matches your real situation.

lightbulb Real-Life Example
35-year-old planning for 60: A 35-year-old with current monthly expenses of ₹60,000 wants to retire at 60 with a corpus that lasts 25 years.
1With 6% inflation, monthly expenses at 60 rise to about ₹2.58 lakh; assuming a 7% post-retirement return over a 25-year payout, the calculator estimates a required corpus of roughly ₹5.5-6 crore, needing a monthly SIP of about ₹35,000-40,000 at an assumed 11% pre-retirement return.
2Now change one input, such as rate, time, quantity, unit or score, and compare the new result with the first one.
Small changes in the assumed inflation or post-retirement return rate swing the required corpus by crores, so the numbers should be stress-tested rather than treated as a single fixed target.

Practical Advice

Use the Retirement Planner as a planning tool, not just a number generator. Write down the inputs you used, because the final answer is meaningful only when you remember the assumptions behind it.

If the decision affects money, health, tax, safety, academics or legal compliance, keep a second check ready. That second check may be a bank quote, payslip, official rule, prescription, site measurement, mark sheet or invoice.

Common Mistakes

  • Using today's monthly expense figure directly instead of inflating it to the retirement year — a ₹50,000/month expense today becomes over ₹1.8 lakh/month in 25 years at 6% inflation.
  • Assuming a flat post-retirement return equal to pre-retirement equity returns, when a retiree's portfolio is usually shifted toward safer, lower-yielding debt instruments.
  • Planning for only 15-20 years of retirement instead of 25-30 years, which risks exhausting the corpus while the retiree is still in their late 70s or 80s.
  • Ignoring that healthcare cost inflation typically runs well above general inflation, leaving an underfunded medical buffer in the later retirement years.
  • Entering existing retirement assets like EPF, PPF, or NPS balances as zero, which overstates the "additional corpus needed" figure the calculator produces.

How to Interpret Results

The result shows the lump-sum corpus required at retirement and the monthly SIP needed to reach it — treat the SIP as a minimum starting figure that should be revisited every few years as your expenses, existing savings, and market returns evolve.

A good interpretation looks at both the main result and the supporting values. If a page shows totals, ratios, categories, schedules or warnings, read those together instead of focusing only on the biggest number.

Retirement Planner FAQs

Useful answers for interpreting the output, avoiding mistakes and using the result responsibly.

How does the retirement calculator arrive at the corpus needed figure?
It inflates your current monthly expenses to your retirement year, then calculates the lump sum required to fund that inflated expense for your expected retirement duration at an assumed post-retirement rate of return.
What inflation rate should I use for my expenses?
A general rate of 6-7% is a common planning assumption for overall household expenses in India, though you may want to run the calculator twice — once at a lower and once at a higher rate — to see the range of outcomes.
Why is the required corpus so much larger than what I feel I need today?
Because the figure accounts for decades of compounding inflation on your expenses plus the fact that the corpus itself must keep generating returns while being drawn down for 20-30 years, not just cover one year of costs.
How does the calculator treat existing savings like EPF, PPF, or NPS?
You should enter their projected future value as an offset; the calculator then shows only the additional corpus you still need to build, rather than the full retirement target from scratch.
What return rate should I assume for the years after I retire?
A conservative rate reflecting a debt-heavy portfolio, often lower than your pre-retirement equity-linked assumption, since most retirees reduce equity exposure to protect their income stream from market volatility.
Does the calculator account for a spouse's expenses or joint life expectancy?
Only if you input combined household expenses and the longer of the two life expectancies as your retirement duration — the calculator itself does not automatically add a second person's costs.
What if I want to retire early, before 60?
Enter your target early-retirement age as the retirement year and extend the retirement duration accordingly; the required corpus rises sharply because you have fewer years to accumulate it and more years for it to last.
How often should I recalculate my retirement number?
At least once every 2-3 years, or after any major life change like a new expense, a job change, or a significant market movement in your existing investments.

What is a Retirement Calculator?

A retirement calculator helps you estimate how large a corpus you must accumulate by the time you stop working, so your savings can fund your lifestyle for the next 25–30 years without running out. It accounts for the most critical variable in retirement planning — inflation — by projecting what your current monthly expenses will cost in the future.

This calculator uses the Present Value of an inflation-adjusted annuity to find the exact corpus needed, then applies the SIP (annuity-due) formula to show you the monthly savings required to reach that corpus during your working years.

lightbulb Example Calculation
Scenario: Mr. Arjun Mehta, 30-year-old engineer in Pune — monthly expenses ₹50,000, plans to retire at 60, inflation 6%, investment return 12% p.a.
1Future monthly expense at 60 = 50,000 × (1.06)^30 ≈ ₹2,87,175/mo
2Corpus (PV of 25-yr real annuity at real rate ≈ 5.66%) ≈ ₹3.8 Crore
3Monthly SIP at 12% for 30 years to reach corpus ≈ ₹9,300/mo
✓ Result: Required Corpus ≈ ₹3.8 Crore | Monthly savings ≈ ₹9,300

Retirement Planning Phases

Your strategy must evolve across life stages — here is what to do at each phase

🌱
Accumulation Phase (25–45)
Highest risk capacity, maximum equity allocation. Even small SIPs create massive corpus via compounding over 20–30 years. Focus: grow wealth aggressively.
Start Here
🔄
Consolidation Phase (45–55)
Shift 20–30% from equity to debt. Protect gains. Increase contribution as income peaks. Focus: preserve gains while growing.
Rebalance
🎯
Pre-Retirement Phase (55–60)
Move 50–60% to debt/hybrid. Finalise corpus estimate. Decide annuity vs SWP. Setup emergency fund for first 2 years of retirement.
Prepare
💰
Early Retirement (60–70)
Withdrawal phase begins. Use SWP from balanced funds. Keep 2-year expenses in FD. Review annual withdrawal rate vs portfolio return.
Withdraw
🏦
Late Retirement (70+)
Increase debt allocation (70–80%). Simplify portfolio — fewer funds, more FD. Ensure nominee and will are updated. Consider annuity for guaranteed income.
Simplify
🎁
Legacy Planning
Plan inheritance for children. Use WILL, nominee registration, trust if needed. NPS, PPF, insurance benefits pass to nominee. Avoid intestate succession complications.

8 Retirement Planning Mistakes to Avoid

These mistakes cost far more than bad market timing — avoid them at all costs

1
Starting Retirement Planning After 40
Starting at 25 with ₹5,000/month at 12% gives ₹1.76 crore by 60. Starting at 40 requires ₹36,000/month for the same corpus. Time is the biggest variable — start the day you earn your first salary.
2
Underestimating Life Expectancy
Plan for 30 years of retirement (till age 90), not 15. Medical advances mean more people live past 85. Running out of money at 80 is a catastrophe — build conservatively and plan for the long run.
3
Ignoring Healthcare Inflation
Medical inflation is 10–12% p.a., double the general inflation. Get adequate health insurance (₹25–50L family floater) and keep a separate medical emergency fund alongside your retirement corpus.
4
Depending Only on EPF/PPF
EPF and PPF at 7–8% returns struggle to beat inflation after tax. They are base instruments. Supplement with equity mutual funds, NPS, and direct equity for real wealth creation over 20–30 years.
5
Withdrawing EPF on Job Change
Every EPF withdrawal resets the compounding clock. The last 10 years of EPF compounding build 60% of the total corpus. Transfer EPF via UAN; never withdraw unless absolutely necessary.
6
Not Accounting for Inflation in Corpus Calculation
Calculating corpus based on today's expenses without inflation adjustment underestimates by 2–3×. ₹50,000/month today becomes ₹1.6 lakh in 30 years at 4% inflation. Always use future value of expenses.
7
Retiring With Debt
Any EMI in retirement eats directly into fixed income. Clear all loans before retiring. Home loan especially — if you retire with an EMI, your effective monthly income drops significantly and corpus depletes faster.
8
No Will or Succession Plan
Dying intestate (without a will) means the court decides asset distribution. This can take years and cause family conflict. Write a will, register nominees in all accounts, and review every 5 years.

Retirement Planning — Frequently Asked Questions

Clear answers to the most important retirement questions for Indian investors

How much corpus do I need to retire in India?
The corpus depends on your current monthly expenses, inflation rate, expected retirement age, and how long you plan to live post-retirement. A common rule of thumb is the "25× rule" — multiply your annual retirement expenses (in today's money, inflation-adjusted) by 25. However, this assumes a 4% withdrawal rate and 30+ years of investment returns; for India's higher inflation, many planners use 28–33× to be safe. Use this calculator with your actual numbers for a precise figure.
What is the 4% withdrawal rule?
The 4% rule, derived from the US Trinity Study, states that you can withdraw 4% of your corpus annually in retirement, with the portfolio likely lasting 30 years. For India, where inflation averages 6% and life expectancy is rising, many advisors recommend a 3–3.5% withdrawal rate to be conservative. At 3.5%: corpus needed = annual retirement expenses ÷ 0.035. This calculator uses the PV-of-annuity method with real (inflation-adjusted) returns, which is more precise than the flat 4% rule.
How do I calculate how much to save monthly for retirement?
First, calculate your required corpus (what you need at retirement age). Then work backwards using the SIP formula: Monthly savings = Corpus × r / ((1+r)^n − 1) / (1+r), where r is the monthly investment return and n is the number of months until retirement. This is exactly what this calculator does live — just adjust the sliders and the monthly savings figure updates instantly. The key insight: starting 10 years earlier can reduce your required monthly savings by 60% or more.
What is the ideal asset allocation for retirement?
A widely used rule of thumb is "100 minus your age" in equity — so at 30, keep 70% in equity and 30% in debt, shifting annually. During the accumulation phase (age 25–45), favour 80–90% equity for maximum growth. As you approach retirement (55–60), shift to 40–50% equity and 50–60% debt/hybrid. In early retirement (60–70), aim for 30–40% equity to balance growth with stability. Post 70, move 70–80% to FD and debt instruments for capital preservation and guaranteed income.
Should I use SWP or annuity after retirement?
Both have merits. A Systematic Withdrawal Plan (SWP) from mutual funds keeps your capital invested and growing — it is flexible, tax-efficient (only gains taxed), and you retain control of the corpus. An annuity from an insurance company provides guaranteed lifetime income but is inflexible, lower-yielding (4–6%), and your capital is surrendered permanently. Most financial planners recommend a hybrid: use SWP for the first 10–15 years of retirement when you are healthy and active, and shift partially to annuity (for guaranteed income) after age 75.
Is ₹1 crore enough to retire in India?
₹1 crore is insufficient for comfortable retirement for most urban Indians today, and will be even less adequate in the future due to inflation. At a 4% withdrawal rate, ₹1 crore generates ₹4 lakh/year (₹33,000/month) in today's money — barely enough in a metro city. If you retire in 20 years, that ₹33,000/month in today's terms would be ₹1.06 lakh/month at 6% inflation. You would likely need ₹3–5 crore minimum for a comfortable 25-year retirement in most Indian cities, depending on your lifestyle.
What are the best investments for retirement in India?
A diversified retirement portfolio for India typically includes: (1) Equity mutual funds via SIP (Nifty 50 index + flexi-cap) for growth during accumulation, (2) NPS (Tier 1) for tax benefits under 80CCD(1B) and partial annuity discipline, (3) PPF for guaranteed EEE tax-free returns over 15 years, (4) EPF — preserve and grow via UAN, never withdraw on job change, (5) FD/RD for the first 2 years of retirement expenses kept liquid. Avoid traditional endowment plans — they give 4–5% returns, well below inflation over 20–30 years.
How does inflation affect retirement planning?
Inflation is the single biggest threat to retirement security. At 6% inflation, prices double every 12 years — so ₹50,000/month today costs ₹1.6 lakh/month in 20 years and ₹2.87 lakh/month in 30 years. This means your corpus must be much larger than naively calculated — and it must continue earning real returns (above inflation) even after you retire. Even a 1% higher inflation assumption can increase the required corpus by 15–20% over 30 years, which is why this calculator uses inflation-adjusted (real rate) formulas throughout.
When should I start investing for retirement?
The answer is always: today, regardless of your age. The mathematics of compounding is brutally unforgiving about delay. Starting at 25 with ₹5,000/month at 12% CAGR gives ₹1.76 crore by age 60 (35 years). Starting at 35 with ₹5,000/month gives only ₹52 lakh by 60 — 3.4× less despite only a 10-year delay. To achieve the same ₹1.76 crore starting at 35, you would need to invest ₹17,000/month. The first ₹5,000/month you invest at 25 does the work of ₹17,000/month started at 35.
What is early retirement (FIRE) and how to achieve it?
FIRE (Financial Independence, Retire Early) is a movement to accumulate 25–33× your annual expenses fast enough to retire in your 40s or even 30s. To achieve FIRE in India: (1) maximise savings rate — aim for 50–70% of income, (2) aggressively invest in equity mutual funds and direct stocks, (3) keep lifestyle inflation low, (4) build multiple income streams (rental, freelance, dividends), (5) calculate your FIRE number (annual expenses × 33) and track progress monthly. A 50% savings rate can achieve FIRE in under 15 years even at a moderate income, compared to 40 years at a typical 20% savings rate.
