In short: Estimate retirement corpus from future annual spending, retirement length, inflation, post-tax return and pension income. A single multiple of salary is only a rough cross-check.
Step 1: current spending
Start with annual household expenses, remove costs that end before retirement and add healthcare, travel, rent and dependent support likely to remain.
Step 2: inflate
Future expense = current expense Γ (1 + inflation)^years. Use separate assumptions where healthcare inflation may differ from general living costs.
Step 3: fund withdrawals
Model yearly cash flows through a long life, not a fixed return forever. Use conservative post-tax returns and test bad early-market sequences.
Illustration
If todayβs annual retirement spending is βΉ6 lakh and retirement is 20 years away, 6% inflation implies about βΉ19.2 lakh in the first year. This is an assumption, not a forecast.
Improve resilience
Include pension and rent conservatively, keep contingency and healthcare buffers, diversify, rebalance, review yearly and plan nominations and estate documents.
Action checklist
- Write down the goal, amount and deadline.
- Check liquidity, risk, costs, tax and exit restrictions.
- Use only regulated intermediaries and original documents.
- Record assumptions and review after major life or rule changes.
Sources and methodology
We prioritised official Indian regulator, tax authority and industry-body material. Numerical examples are illustrations, not forecasts. Product rates, limits and taxation should be rechecked on the transaction date.
