“How much should I save for retirement?” is one of the biggest and most personal questions in finance.
The amount you need hinges on four moving parts:
Lifestyle expectations (city vs. small‑town living, modest vs. luxury travel)
Future expenses (daily needs, healthcare, hobbies, housing upgrades)
Inflation’s silent bite (prices double roughly every 12 years at 6 % inflation)
Investment returns and volatility (equity booms and busts, bond yields, tax drag)
By estimating these variables and committing to a structured savings plan, you lay the groundwork for a financially secure, stress‑free retirement, even if economic conditions change.

Key Concepts
1 . Determining Your Retirement Goal
Begin with a detailed expense sheet, today’s costs plus the extras you hope to enjoy later:
Expense Category | Examples | Notes for Estimation |
|---|---|---|
Core living | Food, utilities, property tax | Inflate at headline CPI (5–7 %) |
Housing | Rent, repairs, senior‑friendly renovations | Own home? Budget upkeep & taxes |
Healthcare | Premiums, medicines, long‑term care | Inflate at 8–10 %—medical costs usually outpace CPI |
Lifestyle | Domestic/foreign travel, hobbies, gifting | Add a buffer for “bucket‑list” years |
Contingency | Unexpected surgeries, family support | Keep at least 10 % of annual spend |
Tip: Many retirees underestimate leisure and healthcare. Over‑budgeting by even 10 % is safer than falling short later.
2 . The 25× Rule—A First Cut
A quick yardstick is 25 × annual expenses, which corresponds to a 4 % starting withdrawal (100 ÷ 4 = 25).
Example
Projected annual spend: ₹10 lakh
Target corpus: 25 × ₹10 lakh = ₹2.5 crore
Limitations:
Longevity risk: If you live beyond 30 years in retirement, a larger corpus or lower withdrawal rate is prudent.
Market crashes: A severe bear market early in retirement (sequence risk) can dent sustainability.
Variable inflation: Higher‑than‑assumed inflation erodes purchasing power faster.
3 . Safe Withdrawal Rate (SWR) Nuances
The classic 4 % Rule—popularised from U.S. data—works as a baseline. Yet Indian retirees face:
Higher expected inflation (often 5–7 %)
Higher equity return potential, but also sharper drawdowns
Less developed annuity markets
Practical ways to adapt:
Guardrails: Withdraw 3–4 % in poor markets; allow up to 5 % after unusually strong years.
Dynamic spending: Reduce discretionary travel in crash years to protect the core corpus.
Longevity ladder: Pair SWR withdrawals with deferred annuities or the Atal Pension Yojana to kick in at age 70–75, covering non‑negotiable expenses if you live very long.
Step-by-Step Guide & Formulas
1. Retirement Corpus Formula
Formula:
Retirement Corpus = Annual Expenses × (1 + Inflation Rate)^Years × Withdrawal Years
Example Calculation:
If your annual expenses are ₹6,00,000, inflation is 5%, and you expect to be retired for 25 years:
Retirement Corpus = 6,00,000 × (1.05)^25 × 25
Retirement Corpus ≈ ₹4.8 Crore
You can use this formula directly in your planning sheet or plug it into your retirement planning calculator.
Tip: investHQ allows you to test these calculations with real mutual fund performance data for better accuracy.
2. SIP Calculation for Retirement Savings
A Systematic Investment Plan (SIP) is one of the most effective ways to build your retirement corpus.
Example:
If you invest ₹15,000 every month in a mutual fund that earns 12% CAGR for 30 years:
Use a SIP formula or calculator to estimate the future value: Future Value = SIP Amount × [{(1 + r)^n – 1} / r] × (1 + r)
Where:
r = monthly interest rate (CAGR / 12)
n = number of months
In this case:
Monthly investment = ₹15,000
Annual CAGR = 12% (or 1% per month)
Tenure = 30 years (360 months)
Future Value ≈ ₹5 Crores
Common Mistakes to Avoid
Underestimating Inflation: A fixed corpus of ₹1 crore may not be enough 20–30 years from now.
Not Diversifying: Avoid relying only on FDs or real estate. Equity mutual funds can deliver inflation-adjusted returns.
Starting Late: Early investing gives compounding more time to grow your savings, reducing the monthly burden later on.
Conclusion
To build a retirement corpus that keeps up with inflation and meets your lifestyle needs, start planning early. Save consistently, diversify investments, and adjust your assumptions regularly. Use investHQ to test and refine your approach before committing to a long-term plan.
