NPS vs PPF vs EPF: Which Builds the Biggest Real Corpus?

In short: PPF and EPF are debt-style, fixed-rate schemes — safe, but their "guaranteed" returns are only a little above inflation, so the real growth is modest. NPS adds equity exposure, so it can build a larger real corpus over decades, but it locks a big chunk into a mandatory annuity at retirement. The right mix depends on your horizon and risk appetite. Model each with the NPS calculator, PPF calculator, and EPF calculator.

The Three, Side by Side

• PPF — fully government-backed, fixed rate (~7% range), 15-year lock-in, tax-free. Zero equity, so returns track a little above inflation.
• EPF — salaried employees' provident fund, employer-matched, fixed rate similar to PPF, largely debt.
• NPS — market-linked with a chosen equity/debt split; lower cost; but at exit, a minimum share must buy an annuity.

PPF and EPF protect capital; NPS reaches for real growth. Neither is "best" in isolation.

The Inflation Lens

A 7% fixed return sounds solid until you set it against Indian inflation of around 3%. The real return on PPF/EPF is often just 1–2% a year — genuinely positive, but slow. NPS's equity portion is what gives it a shot at a materially higher real return over 20–30 years, at the cost of year-to-year volatility.

A Worked Comparison

Common Mistakes

Comparing headline rates, not real returns.

A 7.1% PPF and an 8% EPF look close; after inflation, both are slow-growth. The comparison that matters is against inflation, not against each other.

Ignoring the NPS annuity rule.

A large mandatory share of the NPS corpus must buy an annuity whose fixed payout is then eroded by inflation. Factor that into the "real" retirement income, not just the headline corpus.

Your Next Decision

Think in layers, not winners: use PPF/EPF for the guaranteed core and NPS (or equity funds) for long-horizon real growth. Model your own numbers with the NPS calculator and compare against the PPF calculator.
