Hidden Costs Most People Never Notice: Forex Markup, No-Cost EMI, DCC, Foreclosure Charges, and Insurance Commissions

Some financial charges are stated plainly. Others are buried in a key facts statement, tucked into a footnote, or calculated from a base rate you were never shown. This guide covers five of the most consistently overlooked ones: the forex markup your credit card adds on every international swipe, the very real cost of a “no-cost EMI,” what happens when a foreign ATM offers to convert your bill into rupees before processing it, the prepayment penalty your lender charges when you want to close a loan early, and the commission structure that shapes which insurance product an agent is most likely to recommend to you.

None of these are illegal. Most are disclosed somewhere in the fine print. The problem is that the disclosure is either buried, expressed in jargon, or designed to be looked past rather than looked at. Understanding them takes less time than the money they take from you.

The forex markup: 3.5% plus a tax on the tax

When you swipe a rupee-denominated credit card at a merchant in London or on a US website, your bank converts the foreign currency amount to rupees using its own exchange rate. That rate is not the Visa or Mastercard network rate, and it is not the RBI reference rate. It is those rates plus a markup, which most Indian cards set at 3.5% of the transaction value. On top of that, the bank charges 18% GST on the markup itself. So on a 3.5% markup, you effectively pay 3.5 plus 0.63, or roughly 4.13 pence per pound sterling more than someone transacting in the same currency with a zero-markup card.

On a ₹1 lakh international transaction (a hotel room, a conference registration, an online software subscription) that 4.13% overhead is ₹4,130 that never shows up as a line item you consciously approved. It appears somewhere in the exchange rate applied to the transaction, slightly obscured.

What varies across cards is the markup percentage. A handful of travel and premium cards have brought this number down significantly, and a small set now offer zero markup on foreign transactions, though they often carry an annual fee that offsets part of the saving. The relevant comparison is the total cost of ownership, annual fee plus the expected forex spend, not just the markup headline.

RBI requires banks to disclose the forex markup, and it must appear on each transaction statement. The figure is there if you look. Most people do not look, which is why a multi-city international trip on a standard credit card can cost thousands more than the same trip on a zero-markup card, with no perceptible difference in the experience.

No-cost EMI: cost-free in name, not in practice

The core of no-cost EMI is a pricing arrangement, not an act of generosity. When a retailer (whether a phone brand, an appliance maker, or an e-commerce platform) advertises a product at no-cost EMI, it usually works one of two ways. In the first model, the product’s posted price under EMI is higher than its cash price: the interest is embedded in the price upfront, and the “discount” you see on the EMI page is actually just the removal of that inflated amount. In the second model, the merchant and the bank split the interest cost between them, and the merchant covers its share by not offering you a cash discount.

Either way, the interest does not disappear. It gets relocated. The bank still books interest income on the transaction; it just recovers it differently. What you pay instead of explicit EMI interest is the forgone discount: the saving you would have received had you paid upfront in cash but did not, because the upfront price was the same as the EMI price and you could not see the difference.

The more concrete and less discussed cost is GST on the interest component. Even in a genuine no-cost EMI arrangement where the bank absorbs the interest, 18% GST on that interest amount is passed on to the borrower. For a ₹30,000 phone spread over six months at a notional rate of 15% per annum, the interest component works out to roughly ₹1,400. The 18% GST on ₹1,400 is ₹252, and that appears as a line item on your card statement without much ceremony. Add a processing fee of ₹99 to ₹500 (banks vary), plus 18% GST on that fee, and the true cost of a “free” instalment plan on a ₹30,000 purchase sits somewhere between ₹400 and ₹900, depending on the product and the bank.

This does not mean you should never use no-cost EMI. For large purchases where cash flow matters, the effective cost is still far below what a personal loan would charge. But it is worth knowing that the purchase is not free; it is priced to make you think it is.

Dynamic currency conversion: the foreign ATM’s polite ambush

When you use an Indian credit or debit card at a foreign ATM or point-of-sale terminal, the machine sometimes asks: would you like to pay in Indian rupees or in the local currency? The prompt is framed as a convenience. You recognise the currency, the amount looks familiar, and confirming takes one less mental step than working with pounds or euros. This is called dynamic currency conversion, or DCC, and choosing it almost always costs you more.

The mechanics are straightforward. When you choose DCC, the foreign merchant’s bank does the currency conversion at its own rate: not the Visa or Mastercard wholesale rate that your card issuer would have used. The merchant’s bank sets a rate that includes a markup of between 3% and 8% over the mid-market rate, and that markup goes to the foreign bank and the DCC provider, not to you. You then still get charged your Indian bank’s forex markup on top of the rupee amount. Two markups, stacked.

The correct response to the DCC prompt is to decline and pay in local currency. At an ATM, the option is usually worded as “without conversion” or “continue in local currency.” At a retail terminal, it may appear as a choice between two currency symbols. The key is to never assume that seeing your home currency on the screen is a good sign. In international transactions, it is the opposite.

Online shopping adds a version of this. When you check out on an international website and the price defaults to INR, that is often a DCC trigger. Switching the display currency to the merchant’s local currency before checkout means your card issuer does the conversion at their rate rather than the website’s payment processor doing it at theirs. The saving can be 3% to 8% of the bill, with no other change to the transaction.

Loan foreclosure charges: what closing a loan early actually costs

When you get a windfall (a bonus, an inheritance, a business payout) paying off an outstanding loan is one of the most natural things to do. The loan is gone, the interest stops, and you have one fewer monthly obligation. What some borrowers do not account for is the foreclosure charge, which the lender levies on the outstanding principal at the time of early closure.

The distinction that matters most is whether the loan carries a floating or a fixed interest rate. For floating-rate loans to individual borrowers for non-business purposes, which includes most home loans, the Reserve Bank of India prohibited foreclosure and prepayment charges as far back as 2012 for home loans, and extended that prohibition more broadly with new directions effective January 2026. If you have a floating-rate home loan, you can foreclose it without paying any penalty, regardless of how early in the term you do so.

Fixed-rate loans are different. Banks and NBFCs can, and do, charge prepayment penalties on fixed-rate personal loans, car loans, and business loans, because the lender has locked in a funding cost at the fixed rate and loses when you repay early. These charges are also not small: 2% to 5% of the outstanding principal is typical, with some banks graduating the charge downward as the loan matures.

One thing often missed: lenders are required, after the RBI’s April 2024 Key Facts Statement guidelines, to state the prepayment terms clearly in the loan sanction letter and the KFS. If you are comparing loan offers, the foreclosure clause is worth reading alongside the interest rate, because a loan that is 0.25% cheaper on rate but charges a 4% foreclosure fee can end up costing significantly more if you repay it early.

Insurance agent commissions: what the numbers look like from the other side

Insurance in India is sold, not bought. That is not a criticism of agents: selling is work, and agents deserve to be compensated for it. But understanding how they are compensated explains a great deal about what products dominate the market and why certain plans get recommended more often than others.

The commission structure under IRDAI regulations is not flat. For traditional endowment policies with a premium payment term of twelve years or more, the first-year commission can be 25% to 35% of the annual premium. LIC agents earn on the higher end of this band. For the same person buying a pure term insurance plan, which provides a death benefit but no maturity amount, and is the product most financial advisers recommend for coverage purposes: the first-year commission is around 35% of the first-year premium too, but the premium itself is dramatically lower. A ₹1 crore term cover for a 35-year-old might cost ₹10,000 to ₹14,000 annually. The same person buying a ₹25 lakh endowment policy might pay ₹80,000 annually. The commission percentage may be similar; the absolute rupee amount is not.

ULIPs, unit-linked insurance plans, were heavily regulated after 2010 following public controversy about high charges. The commission cap on ULIPs is around 4% of premium in the first year, which is why ULIPs are rarely the first product a walk-in agent recommends. Renewal commissions across all product types are lower than first-year commissions, which creates a structural incentive to sell new policies rather than service existing ones.

There is a separate but related dynamic worth knowing: persistency commissions. Some IRDAI proposals link additional commission to whether a policyholder continues to pay premiums over five, ten, or fifteen years. In principle, this aligns agent incentives with long-term policyholder outcomes. In practice, it does not yet fully counteract the first-year commission advantage of endowment policies over term plans.

None of this means your agent is dishonest. It means the system they operate in rewards certain recommendations more than others, and that knowing the commission structure helps you understand a recommendation: particularly when an agent suggests switching from your existing term cover to a new endowment plan, or proposes surrendering a ULIP to buy something with a higher upfront commission.

What to do with all of this

The throughline across all five of these costs is the same: each is more visible once you know what to look for, and far less visible when you are focused on the headline number: the price tag, the interest rate, the premium. The forex markup appears in the exchange rate, not as a separate line. The no-cost EMI cost appears as a GST charge you might assume is routine. DCC is framed as a convenience. Foreclosure charges appear only when you ask for a closure statement. And the commission structure is not on the document your agent hands you.

For international spends: compare the forex markup on your card before travel, not after. For EMI: check whether a cash price exists and what the GST line on the statement will say. For DCC: read every currency prompt at a foreign terminal or checkout page, and always choose local currency. For loans: read the KFS for the prepayment clause before signing, not when you want to foreclose. For insurance: ask the agent for the commission structure on what they are recommending, and compare it with the commission on a term plan offering equivalent coverage. In all five cases, the information is available. The cost is only hidden until you look.
