Retirement

Inflation and real returns

Why 8% can be 2% — nominal, real and the withdrawal maths that must respect both.

Every retirement number you have seen — corpus targets, withdrawal rates, 'the fund returned 12%' — is nominal unless stated otherwise. Prices compound against it the whole way. A 30-year retirement is less an investment problem than an inflation problem: the return you keep is the real return, and the withdrawal you need grows every year whether or not your corpus does.

The real-return approximation, and when it lies

Real return ≈ nominal return − inflation works for small numbers: 8% against 6% inflation is roughly 2% real. The exact relation is (1 + r) ÷ (1 + i) − 1, which at 8% and 6% gives 1.89% — and the gap widens as either number grows. Over 30 years the difference between 2% and 1.89% real compounds into lakhs on a crore-scale corpus, so the calculators here never use the shortcut.

What inflation does to a fixed income

At 6% inflation, ₹60,000 a month today needs about ₹1.07 lakh in ten years and ₹1.92 lakh in twenty to buy the same basket — even if the corpus paying it never wobbles. Annuities that pay level for life, EPF interest drawn down, and flat SWPs all share this flaw: the rupee count is constant while the rupee's meaning shrinks. Any payout you design must step up, and the corpus must be sized for the stepping-up, not the first year.

Retirement is where asset mix earns its keep

Debt-heavy portfolios feel safe and lose to inflation after tax — 7.1% PPF interest at 30% slab is roughly 4.5% after tax, below or near long-run consumer inflation. Equity has carried Indian real returns over decades but with sequence risk exactly when you start drawing. The workable answer most plans converge on is a split: enough near-term spending in debt to survive a bad market, enough growth assets to outpace three decades of prices.

Measure everything in today's rupees

The withdrawal planner reports both the nominal end balance and its value in today's rupees, because '₹6.6 crore left in 2056' is a statement about 2026 only after deflating it. Read the real column when judging whether a plan works; read the nominal column when matching against balances you will actually see.

Questions on inflation and real returns

What is a 'real return' and why should I care?

The return left after inflation — (1 + nominal) ÷ (1 + inflation) − 1. It is the only return that buys anything. An 8% portfolio at 6% inflation is about 1.9% real, and a withdrawal plan sized on the nominal number runs out of buying power long before it runs out of rupees.

How much will ₹60,000 a month be worth in 20 years?

At 6% inflation, the same basket costs about ₹1.92 lakh a month in 20 years (₹60,000 × 1.06²⁰). Use the inflation calculator to test other rates and horizons — the point is that any retirement income must grow by roughly the inflation rate every year to stay the same income.

Do the retirement tools assume inflation for me?

No. Inflation is an input you set — the planner steps your withdrawal up once a year by the rate you enter and reports the end balance in today's rupees. The site publishes no inflation forecast; the tools make your assumption explicit instead of hiding one in the code.

Educational, not advisory — and never a projection. LetsInvest is a research publication, not a SEBI-registered investment adviser, and we run no live rates or returns feed. The withdrawal planner and corpus check are illustrations of numbers you enter. Confirm anything that matters with the scheme's own authority (PFRDA, EPFO, the post office or your fund house) before you act.
