What the bank does not print

The collection at source is published to the rupee, but the margin a bank adds to the exchange rate it gives is not published at all. A reader can compute one and cannot compute the other, and the difference is a cost that nobody prints.

One cost is published

The collection at source is published to the rupee, and the rule is in the Finance Act. A reader can compute the collection on any amount, and the table on this site does that arithmetic at a live rate.

The collection is not hidden; it is stated in the law and the bank must show it on the advice. A reader can see exactly how much is collected before the transfer leaves.

One cost is not

The margin a bank adds to the exchange rate it gives is not published by any of them. The bank gives a rate that includes its margin, but the margin itself is not printed, and the reader cannot compute it from the advice alone.

The margin is the difference between the rate the bank gives and the market rate at that hour. A reader who wants to know the margin must compare the two rates, and the comparison is not always possible.

How to see the margin

A reader can see the margin by comparing the rate on the advice against the market rate at that hour. The market rate is available from independent sources, and the difference is the bank's margin plus any other costs.

The comparison is not exact, because the market rate moves and the bank's rate is fixed for the transfer. But a large difference is a sign that the margin is large, and the reader can ask the bank to explain it.

This site does not estimate it

This site does not estimate the margin, because an estimate would be a number invented by this desk. The table carries only what the rule states and what the two rate sources agree on, and the unpublished margin is a fact of the market.

A reader who wants the margin must ask the bank before the transfer. The bank may not give a straight answer, but the question is worth asking, because the margin is a real cost and it is not published.

The silence is a fact

The silence on the margin is a fact, not an omission on this site's part. No bank publishes its margin, and no regulator requires it. A reader who compares banks may find that the rates differ, but the difference is not the margin alone.

The reader should compare the total cost of the transfer: the collection, the margin, and any other fees. The collection is published; the margin is not; and the reader should not confuse the two.

What a reader should ask

A reader should ask the bank for the exchange rate it will actually give, and for the amount in rupees that will be debited and the amount in dollars that will be credited. The difference between the two is the total cost, including the margin.

The bank may not itemise the margin, but the reader can compare the rate against the market rate at that hour. The comparison is the only way to see the margin, because the bank will not print it.

The margin is set at the desk, not by the market

The rupee-dollar rate a reader sees on a finance portal is not the rate the bank uses when money is sent abroad. Banks add a spread to the interbank rate to cover their costs and earn from the transaction. This spread is decided by the bank's treasury or retail desk, and it can change during the day without notice. A reader who checks the rate in the morning and sends money in the afternoon may pay a different margin than the morning quote implied.

The margin is not uniform across banks. A public sector bank may keep it thin for large remittances, while a private bank may charge more for small amounts. Some banks offer better rates to customers who maintain higher balances or have a long relationship. A reader who sends money regularly may find that the margin varies from one transfer to the next even when the interbank rate is stable.

Because the margin is set at the desk, the final rate is known only after the transaction is booked. The receipt shows the rupee amount debited and the foreign currency credited, but not the margin as a separate line. A reader can work backwards to find the effective rate, but the bank will not print the spread it applied.

The margin moves against the reader when urgency is high

A reader who needs to send money quickly, perhaps to meet a payment deadline abroad, has less room to negotiate or compare rates. The bank knows that urgency, and the margin can widen. A transfer made at the branch counter with a same-day value date often carries a higher spread than one booked online with a two-day settlement.

The time of day also matters. Banks widen their margins during volatile market hours or when liquidity is thin, such as early morning or late evening. A reader who sends money when the rupee is weakening may find that the bank's rate is worse than the interbank rate suggested minutes earlier. The bank is not obliged to pass on every market move.

The margin is not a fixed fee, so a reader cannot plan for it the way one plans for a flat commission. It is a percentage of the amount sent, and it scales with the size of the remittance. A large transfer can carry a small margin and still cost a lot in absolute rupees, while a small transfer can carry a wide margin and cost little in absolute terms but a lot in percentage.

The bank's margin is not the only unpublished cost

When money is sent abroad for buying shares, there is often a second conversion cost. The bank may convert rupees to dollars at one rate and then, if the broker or intermediary needs a different currency, convert again at another rate. Each conversion carries its own margin, and the second margin is even less visible than the first.

Some banks route international transfers through correspondent banks, which can deduct a fee from the amount that arrives. This fee is not always disclosed at the time of booking. The sending bank may not know the exact charge the correspondent will apply, or it may not reveal it. A reader who sends money to a US broker may find that the amount credited is slightly less than the amount sent, even before the tax collection is considered.

The silence around these costs means a reader cannot reconstruct the full expense of a remittance from the bank's receipt alone. The receipt shows the debit and the credit, but not the path the money took or the hands it passed through. That path is where some of the cost disappears from view.

The margin interacts with the tax collection in a hidden way

The tax collected at source is calculated on the total amount remitted, not on the amount that finally reaches the foreign account. If the bank's margin is embedded in the exchange rate, the rupee amount remitted includes the margin. The tax is then collected on a sum that is partly the bank's earning, not the reader's money.

This means a reader pays tax collection on the cost of the transfer itself. The bank charges a margin, and the government collects a fifth of the total remittance above the threshold, which includes that margin. The reader's own money is frozen on a larger base than the actual foreign currency value received.

When the credit is claimed at the time of filing the return, the reader gets back the tax collected, but not the margin. The margin is a real cost. The tax collection is a temporary freeze. The interaction between the two means the reader's cash outflow is higher than the foreign investment amount, and the timing of the return affects when the frozen part comes back.

The margin is invisible in the receipt, but visible in the rate

A reader can find the margin by comparing the rate on the bank's receipt with the interbank rate at the time of the transaction. The interbank rate is published by financial data services, though with a slight delay. The difference between the two rates is the bank's spread. This calculation is not done by the bank for the reader; the reader must do it.

The receipt from the bank typically shows the rupee amount debited, the foreign currency amount credited, and an exchange rate. That exchange rate is the bank's retail rate, which includes the margin. The interbank rate is not printed on the receipt. A reader who does not know the interbank rate cannot see the margin.

Because the margin is not printed, many readers assume the exchange rate is the market rate. They compare the bank's rate with what they saw on a currency app and find a small difference, not realising that the app may show a mid-market rate with no spread. The bank's rate includes the cost of doing business, which is fair, but that cost is not disclosed as a separate item.

Asking for the margin may change it

A reader who asks the bank for the margin or the effective rate before sending money may get a better rate than one who simply accepts the quoted rate. Banks often have some room to negotiate, especially for large amounts. A customer who has alternatives, such as another bank or a forex specialist, can use that leverage to ask for a thinner spread.

The margin is not a fixed tariff set by the regulator. It is a commercial decision by the bank, and it can be adjusted for a specific transaction. A reader who sends money regularly may find that the bank offers a preferential rate after a few transactions. The bank values the relationship and the volume of business.

However, not every bank will negotiate, and not every branch has the authority to change the rate. The rate is often set centrally, and the branch staff can only quote what the system shows. A reader who asks may be told that the rate is fixed. In that case, the reader can compare with other banks or wait for a better time, but the margin itself will remain unpublished.
