Spread vs Commission: What Currency Exchange Really Costs

The spread is built into the quoted buying and selling rates; commission is charged separately. The cheapest-looking rate is not always the lowest total cost.

The spread is inside the rate

A currency provider normally quotes a buying price and a higher selling price. The gap between them is the bid–ask spread. Customers do not usually see a separate invoice for it because its effect is already included in the conversion price.

If a bank buys USD at ETB 148 and sells it at ETB 151, the quoted spread is ETB 3 per dollar. The relative spread can be expressed as a percentage of a midpoint or another stated benchmark, but the method should be disclosed when comparing percentages.

Commission is a separate charge

A commission or service fee is added separately. It may be a flat amount, a percentage, or a charge with minimum and maximum values. Transfers can also involve receiving-bank, correspondent-bank, card or delivery charges.

A provider advertising zero commission can still earn through a wider exchange-rate margin. Conversely, a provider charging a visible fee may deliver more currency because its rate is better. Neither label alone reveals the total cost.

Compare the final result

For a cash exchange, calculate how much of the destination currency you receive after the rate and all fees. For a remittance, compare the final amount the recipient receives, the total amount the sender pays and the delivery time. This puts differently structured offers on the same basis.

The World Bank’s remittance-price methodology likewise treats the transfer fee and exchange-rate margin as separate components of total cost. A quoted rate without fees—or a fee without the applied rate—is incomplete information.

Bank exchange and retail forex trading are different

Changing cash or sending a remittance is not the same as leveraged retail forex trading. A trading dealer may charge spreads, commissions, financing and account fees, and the customer may be trading directly against the dealer rather than on an exchange.

The US Commodity Futures Trading Commission warns that fees, spreads, commissions and financing expenses reduce trading results and that most retail over-the-counter forex customers lose money. Ethiopian Forex compares bank rates; it does not recommend speculative trading.

Questions to ask before accepting a quote

Ask which rate applies, whether it is a buying or selling rate, how long the quote remains valid, which fees are added, whether another institution may deduct charges and exactly how much the recipient or customer will receive.

When comparing Ethiopian banks, use the same currency and rate type, then confirm the total directly with the provider. Published rates can change and do not guarantee foreign-currency availability.
