Does an Indian FD really beat a savings account back where you live? Compare both — with the currency and tax built in
How this works: Take one lump sum and see where it grows more — an Indian FD (NRE / FCNR / regular) or a savings/term deposit in your country of residence. We invest the same money on both sides, show each maturity in its own currency, then convert to one currency — plus the exchange-rate cushion that decides whether India's higher rate actually wins.

Overseas side invests at today's rate.

Indian FD — maturity
— maturity
Higher maturity: — by in terms.
The Indian FD stays ahead until 1 = (today ). The rupee could weaken about before the option catches up.
Even at today's rate (1 = ), the option ends up ahead once converted back — India's rate premium doesn't cover the currency gap for these inputs.
A rupee-denominated FD only wins if the rupee doesn't fall by more than the rate advantage over the term.
The maturity is worth different amounts abroad depending on where the rupee lands:
Rupee +10% stronger
Today
Rupee −10% weaker
Holding a rupee asset, a weaker rupee reduces what it's worth in your home currency.
Tax matters here. Interest on an NRE or FCNR deposit is tax-free in India. But if you are a tax resident of the UK, US, Canada, or Australia, that interest is usually still taxable at home as worldwide income — enter your marginal rate above to see the real net. In the Gulf (UAE, Qatar, etc.) there is no such tax, so leave it at 0. NRO deposits are taxed in India (TDS up to 30%) as well.
Estimates only. Assumes a fixed rate for the full term and converts the India maturity at today's exchange rate for comparison — actual future rates will differ. Excludes premature-withdrawal penalties and any wealth/withholding taxes. Not financial advice.
Every Indian bank’s website has a fixed-deposit calculator, and every one of them answers a single question: how much will my rupees grow to? For an NRI, that is only half the story. The money you are thinking of putting into an Indian FD often starts as pounds, dollars, or dirhams — and it may eventually need to be spent in that same currency. So the number that actually matters is not the rupee maturity value; it is what that maturity is worth back in your own currency, after tax, once the exchange rate has had its say.
This calculator runs the comparison properly. It invests the same lump sum on both sides — an Indian FD and a savings or term deposit in your country of residence — and shows each maturity in its own currency, then side by side in one currency of your choice.
The single most common NRI mistake is comparing interest rates directly. An Indian FD at 7% looks like it must beat a UK account at 4.5% or a Gulf deposit at 4%. But the Indian FD is denominated in rupees, and if the rupee weakens over the term of the deposit, the extra interest can be quietly cancelled out when you convert back. The calculator surfaces this with an exchange-rate cushion: the amount the rupee can depreciate before the higher Indian rate stops paying off. If that cushion is large, the Indian FD is a robust choice; if it is thin, you are really making a currency bet, not an interest-rate decision.
The second thing a plain FD calculator hides is tax. Interest on an NRE or FCNR deposit is tax-free in India — a genuine benefit — but tax residence is what determines your overall bill. A resident of the UK, US, Canada, or Australia will usually owe tax at home on that interest as part of worldwide income, which shrinks the real return. A resident of the UAE or another Gulf state pays nothing, so the Indian FD keeps its full advantage. The optional tax field lets you enter your own marginal rate so the comparison reflects your actual net position rather than a headline number. For the fuller picture, our FD rate comparison shows current NRE rates across banks, and the home loan calculator applies the same dual-currency logic to borrowing.
Enter the amount you are considering, choose whether it starts in rupees or your foreign currency, set the term, and adjust each side’s rate to match a real offer. Add your marginal tax rate if your home country taxes the interest. Then read three things: which side has the higher maturity in your chosen currency, how big the exchange-rate cushion is, and what your Indian maturity would be worth abroad if the rupee moved. Let those three numbers — not the headline interest rate — guide the decision.
NRIWallah does not provide financial or tax advice. This calculator is a planning aid that converts future rupee values at today’s exchange rate and assumes a fixed rate for the full term. Real returns depend on future exchange rates, tax rules, and deposit terms. Confirm every figure with your bank and a qualified adviser before investing.
