Retirement Planning in Thane: Corpus, Inflation and Withdrawal

The number nobody calculates correctly

Most retirement conversations start with a corpus target and end with a SIP. Both are outputs. The input is your current monthly expense, inflated to the year you retire.

A household spending ₹1 lakh a month today, retiring in 25 years at 6% inflation, needs roughly ₹4.3 lakh a month in the first year of retirement just to maintain the same lifestyle. That is the number the corpus has to fund — not ₹1 lakh. Almost every under-funded retirement plan we review has made this single error.

Run your own version on the inflation calculator before reading further. The rest of the plan depends on it.

How much corpus is enough?

The widely quoted 4% rule comes from US data and assumes a 30-year retirement with US inflation. India's inflation profile is different, and Indian retirees typically have fewer fallback options. A more conservative planning range for a 30-year Indian retirement is a 3%–3.5% initial withdrawal rate, reviewed annually.

At a 3.5% withdrawal rate, a ₹4.3 lakh monthly requirement implies a corpus of roughly ₹14.7 crore. At 4%, roughly ₹12.9 crore. The gap between those two numbers — nearly ₹2 crore — is the price of being wrong about longevity.

This is why we do not use a single number. We model three scenarios: retire at plan, retire five years early, and live to 95. If the plan only works in the middle scenario, it is not a plan.

The bucket strategy

The biggest risk in retirement is not a low average return. It is a bad return in the first three years, combined with withdrawals — sequence-of-returns risk. Selling equity at a 30% drawdown to fund groceries permanently impairs the portfolio.

The fix is to hold the portfolio in three buckets:

This structure lets a retiree stay invested in equity through a crash, because the next three years of expenses are already sitting in bucket 1. It converts an emotional decision into a mechanical one.

Where the money comes from: EPF, NPS, PPF, mutual funds

EPF and VPF

Employees' Provident Fund is the largest single retirement asset for most salaried Indians, and it is usually the most under-managed. The corpus is debt-heavy, which is appropriate for safety but insufficient for inflation-beating growth over 25 years. It should be treated as the stable layer, not the whole plan.

NPS

The National Pension System offers an additional deduction and a market-linked corpus, with the trade-off that a portion must be annuitised at exit. It suits investors who want a disciplined, low-cost, equity-exposed retirement sleeve and who can live with the lock-in.

Mutual funds

This is where the growth layer lives, and where the SIP discipline matters most. A retirement portfolio built through mutual funds needs an asset allocation that shifts down as the date approaches — typically from equity-heavy 25 years out to debt-heavy 3 years out.

Annuities

An immediate annuity converts a lump sum into a guaranteed lifetime income. The yield is usually lower than a balanced portfolio's expected return, but it removes longevity risk entirely. For most retirees the right answer is a partial annuitisation — enough to cover essential expenses, with the rest staying invested.

Withdrawal mechanics: SWP and the tax layer

A Systematic Withdrawal Plan from a mutual fund is the cleanest way to generate monthly income, but the tax treatment matters. Each SWP instalment is a redemption, so it triggers capital gains in the same way a sale would.

• Equity-oriented funds: 12.5% on long-term gains above ₹1.25 lakh per financial year, 20% on short-term gains.
• Debt and specified funds acquired on or after 1 April 2023: taxed at the investor's slab rate regardless of holding period.

That changes the optimal withdrawal order. Drawing from equity first to use the ₹1.25 lakh exemption, then from debt, is often cheaper than the reverse. Our mutual fund taxation guide works through the sequencing, and the SWP calculator lets you test withdrawal rates.

FIRE: when the maths actually works

The FIRE movement's core insight — that a high savings rate compresses the working years — is sound. The failure mode is applying a 4% rule built for a 30-year US retirement to a 45-year Indian one. A retiree at 45 needs a materially lower withdrawal rate, and needs a plan for health insurance that is not tied to an employer.

Our FIRE planning service models the actual constraint: not "can I stop working", but "what is the probability I run out of money before 90".

The mistakes that cost the most

1. Planning on today's expenses without inflating them.
2. Underestimating health costs, which rise faster than general inflation and are largest at the end.
3. Being equity-heavy on the retirement date, which forces a sale in the first drawdown.
4. No bucket 1, so every market fall becomes a cash-flow crisis.
5. Ignoring the tax on withdrawals, which quietly reduces the sustainable withdrawal rate.
