Picture the counter at a bank branch. A screen behind the teller shows two numbers for the same currency, one for buying and one for selling. You see one of them, and a fee on a slip. What you don’t see is everything between the screen and the slip. This guide walks through that gap, step by step, and points out who gets paid at each one.
The starting point: one price, two prices
In wholesale currency markets there’s a price that sits in the middle of what buyers are bidding and sellers are asking. People call it the mid-market rate. It’s the benchmark you see on a converter, including our USD to INR page. It’s a reference point. Nobody promises you can actually trade at it.
Why not? Because a dealer who buys and sells currency for a living needs to be paid, and the simplest way is to quote two prices. They’ll buy from you slightly below the middle and sell to you slightly above it. The gap between those two quotes is the spread.
That’s the plumbing in one sentence. Everything else is a variation on who takes a slice of that gap, and who adds a slice on top.
Spread versus markup: the same idea, different owners
People use these words loosely, so let’s pin them down.
The spread is the distance between a buy price and a sell price. On the busiest pairs in wholesale markets it can be tiny. On thinly traded currencies it’s wider, because the dealer carries more risk of being stuck holding something nobody wants.
The markup is what a bank or provider adds when it hands the rate to you. The Financial Consumer Agency of Canada describes it as the gap between the mid-market rate and the rate applied to your transaction, and says that data it reviewed indicate markups typically sit between about 1% and 4%, varying by bank, currency pair and market conditions (page dated October 2026). Some fintech providers charge less or none, it adds.
Notice the catch in that same page: banks disclose the rate they applied, but they don’t disclose the markup as its own line. It has to be worked out after the fact by comparing your rate with the mid-market one. That’s the whole trick. The charge exists, it just doesn’t have a name on your receipt.
The three places money leaves your pocket
Think of an international transfer as a relay race with three runners, and each one can take a little something when they hand over the baton.
1. The flat or percentage fee
This is the one printed on the screen. A fixed amount, a percentage of what you send, or a mix. It’s easy to see, which is exactly why providers like to make it look small, or zero.
2. The markup inside the rate
This is the one that works quietly. Say a provider advertises “no fees”. The money still has to go from one currency to another, and if the rate it gives you is a bit worse than the middle, that difference is its pay. A zero fee with a poor rate is a charge wearing a disguise.
3. Fees taken along the route
When a payment travels through several banks, some of them may deduct a charge on the way, so the recipient gets less than you expected. Whether this applies depends on the route and the providers involved. Ask before you send, and ask what the recipient will actually receive.
A worked example (all numbers illustrative)
Say you’re sending 1,000 US dollars to India. Suppose the mid-market rate that morning is 85.00 rupees per dollar. These figures are made up to show the arithmetic, not a quote from anyone.
| Option A: “bank-style” | Option B: “transfer-service-style” | |
|---|---|---|
| Flat fee | 15.00 USD | 4.50 USD |
| Rate you’re given | 83.30 | 84.60 |
| Markup versus 85.00 | 2.00% | about 0.47% |
| Amount converted | 985.00 USD | 995.50 USD |
| Rupees received | 82,050.50 | 84,219.30 |
| Shortfall against a perfect 85,000 | 2,949.50 INR (about 34.70 USD) | 780.70 INR (about 9.18 USD) |
| Total cost as a share of the amount sent | about 3.47% | about 0.92% |
Look at option A. The fee is 15 dollars, and that’s the number you’d have noticed. The markup cost about 19.70 dollars (985 converted, 1.70 rupees short on each), more than the fee. Take the fee away and A is still 2% worse than the middle on every dollar converted.
That’s the reason a fee comparison alone can mislead you. The cheaper-looking fee can sit next to the worse rate. The only fair comparison is the end result: how much arrives, in the currency the recipient receives, for the same amount sent.
Where each slice goes
Here’s the part counter staff rarely draw on a whiteboard, kept general because the details differ from one firm to the next.
Broadly, the flat fee covers the provider’s cost of running the service and its profit. The markup mostly ends up as the provider’s margin on the currency conversion, though a firm may split some of it with partners such as agents or banks on the other end. If a card is involved, there can also be charges from the card issuer, and in some cases a cut for whoever processes the payment. How these are split is a commercial arrangement, not something you’ll usually see published.
Simplification alert: real pricing is messier than three tidy buckets. Providers can also earn in other ways that aren’t visible to customers. The three buckets are a useful mental model, not an accounting statement.
Card payments abroad: the same story
When you tap a card in another country, the amount gets converted from the shop’s currency into yours. Your card issuer may add its own foreign transaction fee, and it may apply its own rate. Terms differ a lot between issuers, so the honest answer is to read your card’s fee schedule or ask. Many cards charge nothing for foreign use; some charge a percentage. Check yours.
There’s one more trap that deserves its own warning: a terminal that offers to charge you in your home currency instead of the local one. Sometimes called dynamic currency conversion. The rate used there is set by the merchant’s side, not your bank, and it’s usually less friendly. Choosing the local currency is the usual advice.
What the rules say, and what it all adds up to
In some countries, the law makes providers show you the numbers. In the United States, the Consumer Financial Protection Bureau’s remittance rule requires providers sending money abroad to disclose the fees, the exchange rate and the amount to be received by the recipient, and generally gives the sender 30 minutes after payment to cancel (as described by the CFPB when it adopted the rule in 2012; rules can be amended, so check the current version). The bureau also says providers must investigate an error within 90 days and tell you the result.
Other countries have their own regimes, and the details are not the same. If you’re sending from somewhere else, look up your own regulator’s guidance rather than assuming the US protections apply.
Is that a lot? The World Bank tracks what it costs people to send money home. Its Remittance Prices Worldwide page gives a global average cost of 6.36% of the amount sent (page last updated August 2025). That’s an average across many corridors and provider types, so any single transfer could be well above or below it. Treat it as a sense of scale: the cost of moving small amounts internationally is, on average, a lot more than most people assume when they see a “low fee” banner.
It also shows why a percentage matters more than a flat amount. A 15-dollar charge on 200 dollars is 7.5%. The same 15 dollars on 5,000 is 0.3%. Small, frequent transfers get hit hardest by flat fees, and large ones are hit hardest by a weak rate.
Five questions to ask before you pay
- What exact rate will I get, and what is the mid-market rate at this moment?
- Besides the fee shown, is there anything else deducted from the amount?
- How much will the recipient receive in their currency, to the last digit?
- Is that amount guaranteed, or can it change before the money lands?
- Can I cancel, and until when?
Then do the sum yourself: multiply the amount you’d convert by the rate, compare it with what the middle rate would have given you, and the gap is your real cost. You can see current mid-market levels for many currencies on our rates grid. Rates refreshed hourly, so check right before you send and compare against the quote in front of you.
Nothing here is financial advice. Providers, rules and prices change, so check the terms with your own bank or provider.
