What exchange rate you actually get
Published: 17 September 2026 · Izračunaj.ba
The converter works from the mid rate: 200 EUR is exactly 391.17 KM, because the mark is pegged to the euro at 1 EUR = 1.95583 KM. That number is a reference, not an offer. An exchange office or a bank earns on the gap between the rate at which it buys and the rate at which it sells, so at a 2% margin the same 200 EUR gets you 383.34 KM — 7.82 KM less. Exchange the money both ways at the same margin and 200 EUR comes back as 192.16 EUR: 3.92% of it goes on two transactions, without the rate moving at all.
The mid rate is a reference, not an offer
Every converter, this one included, works from a single number per currency — the mid rate. By it, 200 EUR is exactly 391.17 KM. That amount is correct as arithmetic and wrong as an expectation: nobody at a counter will hand you precisely that.
The reason is simple: an exchange office has two rates. It buys your currency at the lower one and sells it to you at the higher one, and the gap between them is its earnings. The mid rate sits somewhere between the two and is not the price for either side.
So use the converter for what it is built for — to know what something is worth and whether the offer you were given is close to the reference amount or far from it.

Between the mark and the euro there is no exchange-rate risk: 1 EUR is always 1.95583 KM and that number does not move from day to day. People often conclude from this that exchanging the two is free, which is a different thing.
The table below shows what a margin costs on 200 EUR. The 1, 2 and 3% figures are an example for the arithmetic, not published or average rates — you work out your own margin by comparing the amount you actually received with the mid-rate amount:
| Margin | You get for 200 EUR | Less than at the mid rate |
|---|---|---|
| 0% (mid rate) | 391.17 KM | — |
| 1% | 387.25 KM | 3.91 KM |
| 2% | 383.34 KM | 7.82 KM |
| 3% | 379.43 KM | 11.73 KM |
A two-way exchange is paid for twice
The same arithmetic runs in the other direction. At the mid rate 1,000 KM is 511.29 EUR; at a 2% margin you get 501.27 EUR, so 10.03 EUR less.
If you exchange money and then change your mind and convert it back, you pay the margin twice. At a 2% margin in both directions, 200 EUR comes back as 192.16 EUR — 7.84 EUR gone, or 3.92% of the amount, while the rate itself never moved.
| Margin | You get for 1,000 KM | Less than at the mid rate |
|---|---|---|
| 0% (mid rate) | 511.29 EUR | — |
| 1% | 506.23 EUR | 5.06 EUR |
| 2% | 501.27 EUR | 10.03 EUR |
| 3% | 496.40 EUR | 14.89 EUR |
Pay by card and somebody else picks the rate
A card payment in a foreign currency does not use your bank's counter rate but the card network's rate on the day the transaction is processed. Your bank may add its own foreign-currency fee on top — that is in its fee schedule, not on the slip you sign.
A terminal abroad will often offer to charge you in your own currency instead. That is dynamic currency conversion, and the rate is then set by the merchant's processor rather than the card network. It is almost always worse. To keep the rate with the card network, choose to pay in the currency of the country you are in.
The same applies to cash withdrawals from an ATM abroad, plus the withdrawal fee that machine shows you before you confirm.
Why the euro stands still while the dollar moves daily
The mark's rate against the euro is fixed, so the converter always computes that pair the same way — even with no internet connection. Every other currency has a market rate that changes each working day, so the converter takes those from a public list and shows the date that list refers to next to the result.
That is why no amount in dollars, pounds or francs is worth writing down: tomorrow it is a different number. For the mark and the euro the opposite holds — that ratio is the one in the converter you can simply remember.
For invoices and contracts, the bank's rate on the payment date applies
If you are paying an invoice in a foreign currency or signing a contract with an amount in euros, what counts is the rate the bank applies on the day of execution, not the figure from any converter. The calculation is there so you can check the order of magnitude and avoid surprises.
For a trip it makes sense to add up the other costs at the same time — fuel, tolls and accommodation usually move the budget more than the margin on changing money.
