In brief
- The main mistake when exchanging currency is looking only at the headline rate without factoring in everything else. The gap between an "average" and a "correct" approach costs 1-3% of the amount. On 1,000 USD, that is 700-3,000 rubles per transaction.
- The second most damaging mistake is looking at the wrong column. You need the buy rate if you are selling currency, and the sell rate if you are buying. It is easy to confuse them, and the loss is the entire spread.
- The third is not calling ahead before you visit. One phone call saves a wasted hour of travel, and often a couple of hundred rubles too, by clarifying the details upfront.
- The widget on this page compares Moscow banks for both directions and refreshes hourly. It is your baseline tool.
- Below are 12 common mistakes, ranked from most to least painful, plus a step-by-step checklist for avoiding each one.
Mistake 1: confusing the direction of the transaction
This is the most frustrating mistake, because it happens through inattentiveness rather than a bad choice of bank.
A bank's FX desk shows two rates. The buy rate is the price at which the bank buys currency from you (handing you rubles in return). The sell rate is the price at which the bank sells currency to you (taking your rubles). The gap between them is the spread.
If you are selling 100 USD and look at the sell rate (instead of the buy rate), you may walk in expecting "a rate of 91" only to find the bank actually buys from you at 89. The loss is 200 rubles on 100 USD.
How to avoid it: write down one word for yourself: "selling" or "buying." At the FX desk, that word comes first, then the number.
Mistake 2: not comparing banks
Going to the nearest branch because "the rate is the same everywhere" is a myth. Neighboring banks on the same street can show rates that differ by 30-80 kopecks. That is 30-80 rubles for every 100 USD. On 500 USD, that is 150-400 rubles you give up for nothing.
How to avoid it: open the rate widget before you leave, and compare at least 3 of the top banks for the direction you need.
Mistake 3: rushing to the top-ranked bank without calling
The leader on rate is the leader at the moment the data was last refreshed. By the time you arrive, the rate may have moved. The bank may also be out of cash in the currency you want (especially euros and yuan).
A single call takes 2 minutes. Ask: "Are you taking (or do you have for sale) X dollars/euros/yuan today? What is the rate right now?" If the answer is good, go.
Mistake 4: changing everything at the airport
An airport FX desk is the most expensive option. Airport spreads are 1.5-2 times wider than in the city. On 1,000 USD, that is a 2,000-4,000 ruble gap.
At the airport, exchange only enough for transport and the first hour. Do the rest at a bank in the city. More on this in airport vs. city currency exchange.
Mistake 5: ignoring banknote condition
If you have older USD series (pre-2006) or a damaged banknote (tears, tape, writing), a standard FX desk may offer you a lower rate or refuse the note outright. That is also a loss, just in the form of rejection or a discount.
The fix: sort your banknotes by series and condition in advance. If a note is borderline, take it to a premium branch rather than a standard FX desk. More on this in which dollar bills are accepted in Russia and on damaged notes.
Mistake 6: changing a large amount through a standard FX desk
If you are dealing with the equivalent of 3,000 USD/EUR or more, a standard FX desk is not optimal. The spread there is 1-3%. A premium branch with an individual rate offers 0.5-1%. A foreign-currency account through the mobile app gives 0.3-1%. Going through a broker on the exchange is 0.1-0.5%.
On 5,000 USD, the gap between "standard FX desk" and "broker on the exchange" is 60-145 USD. That is real money. More in on large amounts.
Mistake 7: not calculating the true cost
In currency exchange there is usually no separate "commission" line: everything is rolled into the spread. But the true cost of the transaction is different at different banks.
The formula is simple: (bank's rate minus CBR rate) / CBR rate x 100%. If a bank's figure is above 1.5-2%, that is already a lot. More in on the commission on currency exchange.
Mistake 8: not recounting at the desk
It is standard practice to recount the money you receive without stepping away from the desk. Nobody minds. Once you have walked away from the window, complaints carry far less weight — and on a large amount, any shortfall can be a serious loss.
Do not feel awkward about recounting. It is normal.
Mistake 9: not keeping the receipt
An exchange receipt is needed in several situations:
- If a shortfall or a damaged banknote turns up later, the receipt is your primary document for any claim.
- If you later need to explain the origin of currency at this or another bank, the receipt confirms the source.
- If you leave Russia carrying leftover currency, the receipt can help.
Hold on to the receipt until you have fully spent the money you received.
Mistake 10: exchanging at the wrong time of day or week
Banks update their rates 1-3 times a day, usually following the moves on the exchange. In volatile periods, the spread widens.
The best moments to exchange are typically mid-morning on a weekday, once the exchange has opened and the rate has settled. The worst are Friday evening (the bank prices in weekend risk) and times of sharp moves (any noisy news day).
More on this in the best time to exchange currency.
Mistake 11: giving in to cross-sells
At the FX desk, the teller may pitch extras: "sign up for a card with a better rate," "open a foreign-currency account right now," or "fill in an investment application." These are not part of the exchange — they are marketing offers that may tie you to the bank more than you intended.
A standard exchange transaction means one receipt. If you are being offered something else, ask what exactly and why. Do not sign on autopilot.
Mistake 12: trying to exchange currency with private individuals
"I'll change at a great rate" on a messenger or classifieds site. Beyond the obvious counterfeit risk, this is a legal gray zone: transactions between individuals are not banned, but they have no official protection. On a large amount, the risks are out of proportion to the rate advantage.
Go to a bank.
Master checklist: before you exchange
The day before:
- [ ] You have decided on the direction (selling or buying).
- [ ] You know the amount.
- [ ] You have sorted your banknotes (if selling): good condition, 2006+ series for USD, new series for EUR.
- [ ] You have opened the widget and picked the top 3 banks in the column you need.
- [ ] You have checked the route to 2-3 of the closest branches.
On the day:
- [ ] You have called the chosen bank to confirm the rate and currency availability.
- [ ] You have your ID with you.
- [ ] You have allowed enough time: 15-30 minutes for a routine exchange, 30-60 minutes for a large one.
At the bank:
- [ ] You have cross-checked the rate on the board against the widget and the phone quote.
- [ ] You have asked about the spread (if you plan a round-trip transaction).
- [ ] You have not signed anything beyond the standard receipt.
- [ ] You have recounted the money received without stepping away from the desk.
- [ ] You have kept the receipt.

Not recounting at the desk | Up to 100% on any shortfall | 30 seconds at the desk |
Cross-sells | Depends on the product | Just decline |
Private individuals | Potential 100% loss | Banks only |
FAQ
What is the most common mistake when exchanging currency?
Confusing the direction of the transaction: looking at the buy rate when you are buying (you should be looking at the sell rate), or vice versa. The loss is the entire spread, typically 1-2% of the amount.
How do I compare banks quickly before I head out?
Open the widget on the page, pick the direction (selling/buying) and the currency you need. Note the top 3 banks. It takes 1-2 minutes.
Is it fine to exchange currency at the first FX desk I find?
If the amount is under 100 USD/EUR, it makes almost no difference. Above 500 USD/EUR, it is better to compare 3 banks via the widget.
Can I complain about the rate after the exchange?
About the rate itself, no: the bank sets it. About an amount that was miscalculated, yes, using the receipt for the transaction within the same day (and ideally with the same teller).
What do I do if I am left with a banknote nobody will take?
Submit it for collection at a major bank. Within 1-2 weeks, the bank will either return the note or credit the equivalent rubles to your account after appraisal. More on this in on damaged dollars.
Can I negotiate an individual rate?
From 3,000 USD/EUR upwards, usually yes, through a major bank's premium branch. It is standard practice. More in on large amounts.
