How Neobanks Calculate Exchange Rates vs Banks

Jul 1, 2026

Traditional banks often add hidden markups to exchange rates, while neobanks typically use real-time interbank rates with clear fees. This article explains the differences and provides tips for getting the best deal on currency conversion. Understanding these mechanisms can save you money on international transactions.

When exchanging money for international travel or business, the exchange rate you get can vary dramatically between traditional banks and modern neobanks. While both offer currency conversion services, the way they calculate rates is fundamentally different. Neobanks, which operate entirely online without physical branches, often advertise more transparent and competitive rates. But how do they actually compute these rates, and are they always better? This article breaks down the mechanics.

How Traditional Banks Calculate Exchange Rates

The Retail Rate vs Mid Market Rate

Traditional banks typically use a retail exchange rate that includes a markup over the mid market rate the wholesale rate used between financial institutions. This markup often ranges from 2% to 5% but can be higher for less liquid currencies. The bank adds this margin to cover costs and generate profit, and it is usually built into the quoted rate rather than shown as a separate fee. As a result, the rate you see is already less favorable than the real interbank rate.

Hidden Markups and Fees

In addition to the spread, traditional banks may charge fixed transaction fees or minimum charge amounts. Some advertise zero commission but compensate with a wider spread. The total cost of an international transfer can be opaque, making it difficult to compare offers. For example, a bank might quote a rate of 1.10 USD per EUR when the mid market rate is 1.12 USD per EUR, effectively charging you a 1.8% markup without labeling it as such.

How Neobanks Approach Exchange Rates

Real Time Interbank Rates

Neobanks like Revolut, Wise, and N26 often claim to use the real time mid market rate as their base. They then add a small transparent markup or a fixed fee to generate revenue. This markup is typically much lower than traditional bank spreads, often between 0.1% and 1% depending on the currency pair and the provider. Some neobanks even offer fee free conversions up to a certain monthly limit, then charge a small percentage above that.

Transparent Fee Structures

One key advantage of neobanks is transparency. They display the mid market rate and then show the fee separately, so you know exactly how much you are paying for the conversion. For instance, Wise shows the real exchange rate and then a clearly stated fee (e.g., 0.5% of the amount). This contrasts sharply with traditional banks where the total cost is hidden in the rate. This transparency allows you to compare costs across providers and make informed decisions.

Key Factors That Influence the Rate You Get

Time of Transaction

Exchange rates fluctuate constantly based on market conditions. Neobanks often update rates in real time, so the rate you see when you initiate a transaction is nearly current. Some neobanks allow you to lock in a rate for a short period or set rate alerts. Traditional banks may use less frequent rate updates, which can work in your favor or against you depending on market movements. Additionally, weekends and public holidays may see reduced liquidity and wider spreads.

Currency Pair Liquidity

Major currency pairs like EUR/USD or GBP/USD have high liquidity and therefore tighter spreads. Both banks and neobanks offer better rates for these pairs. Exotic pairs such as Thai Baht to Mexican Peso have lower liquidity and wider spreads. Neobanks may still offer more competitive rates on exotic pairs compared to traditional banks, but the difference might be smaller. Always check the rate for your specific pair.

Practical Tips for Getting the Best Rate

  • Always compare the offered rate against the mid market rate using a reliable source like Google or XE.com. The difference is your true cost.
  • Check for additional fees such as transfer fees, withdrawal fees, or monthly account fees that could offset a good rate.
  • For small to medium amounts (up to a few thousand dollars), neobanks usually provide better value. For very large transfers, consider negotiating with a traditional bank or using a dedicated forex broker.
  • Use rate alert tools offered by some neobanks to convert when the rate is most favorable.
  • Avoid dynamic currency conversion at ATMs or point of sale, as this often includes a poor markup. Instead, choose to be charged in the local currency and let your neobank handle the conversion.

Understanding how neobanks and traditional banks calculate exchange rates empowers you to make cost effective choices. Neobanks generally offer greater transparency and lower overall costs, especially for frequent or modest transactions. However, always verify the exact terms and compare providers before converting currency. By being aware of hidden markups and leveraging real time rates, you can keep more of your money when sending or spending abroad.
