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.

Every year, Kamala’s bank sends her an FD statement, and every year the number is bigger. Seven percent, senior-citizen rate, sixteen lakh where ten used to be. It is the politest theft in Indian finance: the statement grows in rupees while the money shrinks in groceries — and the difference is collected, in part, as tax on interest that was never really income at all.
Kamala’s 7% has two components: roughly 6% that merely keeps pace with inflation — running to stand still — and roughly 1% of real return. The Income Tax Act does not distinguish. It taxes the entire 7% at her slab. At 31.2%, her post-tax return is 4.82% against 6% inflation: a real return of −1.12% a year. The state is taxing the inflation component — compensation for purchasing power its own monetary system eroded — and calling it income. Equity investors get concessional rates; the FD holder, the most conservative saver in the country, gets the harshest treatment in the book.
Above modest thresholds, the bank deducts tax at source on FD interest — before you have seen a rupee. If your total income is below taxable limits, that is your money sitting with the department until a refund; the fix is filing Form 15G (15H for seniors) at the start of each financial year. The system defaults to over-collecting from exactly the people least likely to know the form exists.
Our FD calculator computes what banks do not print: the post-tax, post-inflation value of your maturity amount. Our TDS calculator tells you whether deduction applies to you at all, and what to file to stop it. Between the two, the statement’s politeness stops working.
FY2025-26/26-27 thresholds under Section 194A: ₹50,000/year for regular depositors, ₹1,00,000/year for senior citizens (60+), per bank, across all FDs and RDs combined at that bank. Once interest crosses the threshold, TDS applies to the entire interest amount, not just the excess. Rate is 10% with a valid PAN on file, 20% without one (Section 206AA) — the 20% rate applies even if you'd otherwise owe no tax.
TDS is only an advance, not your final tax. If your total income is below the taxable limit, submit Form 15G (under 60) or 15H (60+) to the bank to stop TDS being deducted at all. If it's already been deducted and your actual liability is lower, you can only get it back by filing an income-tax return and claiming the refund.
FDs are not the enemy — for money you will need in one to three years they are exactly right. The trap is using them as a lifetime wealth strategy. Ladder deposits so nothing auto-renews at counter rates without a decision. File 15G/15H if eligible, every April. Compare post-tax FD returns against alternatives taxed more gently. And for money with a decade of runway, accept that some equity exposure is not bravado — it is the only mainstream escape from politely losing 1% a year, guaranteed.
At 6% inflation, prices also roughly double in 12 years. Nominal doubling over a decade is standing still with better paperwork. Judge every FD by its post-tax, post-inflation rate — the calculator above prints it.
No — safety and predictable income matter more in retirement. But use the senior-specific escapes first: SCSS at higher rates, the 80TTB interest deduction, and 15H to stop needless TDS. Politeness should at least be cheap.
