The Refinance Treadmill: Lower Payment, Longer Sentence
Each refi resets the interest-heavy years and rolls in fresh costs. Keep the rate; keep the clock honest.

Vikram did everything the brochures said. Thirty years of NPS contributions, a crore in the corpus, retirement at 60 like a landing pilot. Then the fine print took over the controls: 40% of his crore — ₹40 lakh — must be handed to an insurance company, by rule, in exchange for a pension priced at whatever the industry offers that year. The annuity pays about 6.5%. It is fully taxable. And it will never, ever grow — while every price he pays for the rest of his life will.
The annuity purchase is not a choice; it is a condition of touching your own money. Insurers know every NPS retiree must walk through their door, and captive demand does what captive demand always does to pricing: annuity rates run at 5.5–7.5% — often below a senior-citizen FD, except the FD returns your capital and the common annuity variants keep it. The 60% you withdraw is tax-free; the pension the other 40% buys is taxed at your slab, every month, as ordinary income.
₹40 lakh at a 6.5% annuity rate: ₹21,667 a month. After 20% tax: about ₹17,333. Now run the tape forward — the pension is frozen while prices are not. At 5% inflation, by the 25th year of retirement that ₹17,333 buys what ₹5,119 buys today. A phone bill and a half. The brochure called this “guaranteed lifetime income”, and technically, none of those words is false.
Retirement is not an event; it is 25–30 years of prices compounding against a flat cheque. Our NPS calculator models exactly this — deferment options, the annuity share, tax on the pension, and what the pension is worth in today’s money at any future year. Most official calculators stop at the corpus, because the corpus is the flattering number.
Every input of the official NPS Trust calculator is here — existing Tier I corpus, contribute-till age, deferred exit (up to 85, corpus compounding without contributions), annual step-up, annuity share and rate, and the desired-pension check with its "raise the contribution or raise the annuity share" options. What the official tool never shows, this one does: the pension after tax and in today's money — the number you will actually live on. (Tier II balances are deliberately out of scope: Tier II is a plain withdrawable investment account with no annuity or exit rules, so it doesn't belong in a pension projection.)
Tax: NPS is nearly-EEE with one taxed leg. The lump sum (up to 60% of corpus at exit) is entirely tax-free. The annuity pension is taxed at your slab as ordinary income — set your expected retirement slab above (0 if total retirement income stays under the ₹12L new-regime rebate). On the way in: your own contributions get 80CCD(1) plus an extra ₹50,000 under 80CCD(1B) — both old regime only — while an employer contribution under 80CCD(2) (up to 14% of Basic+DA) is deductible even in the new regime, the most under-used tax break for salaried India. Partial withdrawals (up to 25% of own contributions, 3 times) are tax-free. Your expected return depends on the scheme mix you pick (equity is capped at 75%); the official calculator's sector/scheme dropdown does nothing more than suggest that number.
Keep contributing — the accumulation-phase tax breaks are real. But plan the exit a decade early, not the year of. Compare annuity variants: “return of purchase price” pays less monthly but leaves the ₹40 lakh to your family; without it, the insurer keeps the corpus when you die. Consider deferring the annuity purchase if rates are poor at your retirement. Structure the tax-free 60% into a growth-plus-SWP engine so something in your retirement rises with prices. And watch the rules — recent reforms have already loosened the annuity share for some subscribers; fine print that giveth can be renegotiated.
It exists for a defensible reason — to stop retirees exhausting the corpus in five years. The grey zone is not the mandate; it is mandating purchase from a concentrated industry at whatever rate prevails on your 60th birthday, then taxing the payout in full.
The annuity variant. The difference between with and without return-of-purchase-price is your family inheriting ₹40 lakh or a condolence letter. Read that page twice.
