The 3.5% Rule (India-Adapted Safe Withdrawal)

The popular 4% rule (from the Trinity Study) assumes US-level inflation of 2-3%. In India, with 5-7% inflation, a safer withdrawal rate is 3.5% per year. Based on your inflation-adjusted annual expenses of 27.57 L at retirement, you need a corpus of 7.88 Cr to follow this rule.

Retirement Planning Tips for India

EPF (Employee Provident Fund): Mandatory 12% of basic salary contribution. Currently earns ~8.25% p.a. tax-free. Your employer matches the contribution. Include your EPF balance in current savings.
NPS (National Pension System): Additional Rs 50,000 tax deduction under Section 80CCD(1B) over the Rs 1.5 lakh 80C limit. Mix equity (up to 75% allocation till age 50) for higher long-term returns.
PPF (Public Provident Fund): Tax-free returns at ~7.1% with 15-year lock-in. Rs 1.5 lakh annual limit under Section 80C. Ideal for the debt portion of your retirement portfolio.
Equity Mutual Funds (SIP): For a 20-30 year horizon, equity has historically returned 12-15% CAGR in India. Start SIPs early and increase by 10% annually (step-up SIP) to beat inflation.
Health Insurance: Medical inflation in India runs at 10-14% p.a. Secure a Rs 25-50 lakh family floater with a super top-up by age 35. Costs rise sharply after 45.
Diversify Across Tax Buckets: Combine EPF (EEE), NPS (EET), PPF (EEE), ELSS (EEE after 1L LTCG), and SCSS/RBI bonds for post-retirement income.

About Retirement Calculator

Retirement planning in India requires bridging two unknowns — how much corpus you will have at retirement and how much you will actually need. This calculator solves both sides: it projects your savings forward using compound growth, then discounts your future expenses back using inflation, revealing whether you are on track or facing a shortfall. It uses the 3.5% safe withdrawal rule adapted for Indian inflation.

How It Works

The corpus needed is calculated by first inflation-adjusting your current monthly expenses to retirement date: Future Monthly Expense = Current Expense × (1 + inflation)^years. Then the annual requirement at retirement is multiplied by 1/SWR (safe withdrawal rate) to find the target corpus: Corpus Needed = (Future Monthly Expense × 12) / 0.035.

The corpus you will accumulate is projected using two components: existing savings grown at the pre-retirement return rate — Grown Savings = Current Savings × (1 + r)^n — plus future SIP contributions: SIP Corpus = Monthly SIP × [(1 + r/12)^(12n) - 1] / (r/12). The calculator then computes the gap or surplus: Surplus/Shortfall = Projected Corpus - Corpus Needed.

Post-retirement, the withdrawal phase simulation draws down the corpus each month (monthly expenses inflated each year) while earning post-retirement returns (typically 7-8% on a conservative debt-heavy portfolio). This gives a year-wise corpus projection showing whether your money lasts your lifetime expectancy, with a warning if the corpus depletes before the expected end of life.

Who Is This For

A 35-year-old couple with Rs 20 lakh in EPF and Rs 25,000 monthly SIP wants to see if they can retire at 55 with Rs 1 lakh/month expenses (today's value).

A 48-year-old professional starting retirement savings late needs to calculate the monthly SIP required to accumulate a Rs 3 crore corpus in 12 years.

A government employee with a defined pension of Rs 60,000/month wants to find the additional corpus needed to cover a Rs 1 lakh monthly lifestyle gap.

A self-employed 40-year-old with irregular income wants to model three scenarios — conservative (7%), moderate (10%), aggressive (12%) — on the same Rs 30,000 monthly investment.

A 60-year-old retiree with Rs 2 crore corpus wants to check how long their money lasts at 3.5% vs 4% withdrawal, accounting for 6% inflation and 8% post-retirement returns.

Scope note: Projections assume constant return rates and inflation — real markets are volatile. Sequence-of-returns risk (early retirement market crash) is not modeled; a 30% crash in year 1 of retirement has a disproportionate impact vs. the same crash in year 10. This calculator does not account for healthcare cost inflation (which typically exceeds general CPI), longevity risk beyond the entered life expectancy, or major life events (children's education, property purchase). Use this as a planning baseline, not a guarantee.

Frequently Asked Questions

It depends on your monthly expenses, inflation, and retirement duration. As a rule of thumb, you need 25-30x your annual expenses at retirement. For example, if your expenses at retirement are Rs 1 lakh/month (Rs 12 lakh/year), you need Rs 3-3.6 crore corpus.

The 4% rule says you can withdraw 4% of your corpus annually without running out of money in 30 years. In India, higher inflation (5-7%) means a safer withdrawal rate is 3-3.5%. This calculator uses the India-adapted 3.5% rule.

Yes. EPF is a major retirement savings vehicle for salaried employees in India. Include your current EPF balance in "Current Savings" and factor the employer contribution into your monthly investment.

Pre-retirement: 10-12% if investing in equity mutual funds via SIP (historical Nifty 50 CAGR is ~12%). Post-retirement: 7-8% with a conservative debt-heavy portfolio (PPF, SCSS, debt funds, annuities).

Inflation erodes purchasing power over time. At 6% inflation, Rs 50,000 today will feel like Rs 1.6 lakh in 20 years. This calculator adjusts all expenses for inflation to give you a realistic retirement corpus target.

The US-originated 4% rule is too aggressive for India due to higher inflation (5-7%) and shorter fixed-income yields. Research suggests a 3-3.5% withdrawal rate (or Rs 3,000-3,500 per Rs 1 lakh corpus annually) is safer for a 25-30 year retirement in India.

If you receive a defined pension (government service, military) or NPS annuity, subtract that monthly amount from your required corpus withdrawal before calculating the lump sum needed. Enter only the gap — the amount your savings must fund — not total expenses.

This calculator assumes level monthly expenses and a constant return rate — both unrealistic over 20-30 years. It does not model sequence-of-returns risk (a market crash early in retirement can be fatal to a corpus).
