Why Is My Exchange Rate Different from Google?
If you have ever looked up an exchange rate on Google and then found that your bank or money transfer provider offers something quite different, you are not alone. The rate Google shows is called the mid-market rate — and it is almost never the rate you actually receive. Understanding why this gap exists, how big it typically is, and how to minimize it is one of the most valuable things you can know before sending money internationally.
What Is the Mid-Market Rate?
The mid-market rate (also called the interbank rate or spot rate) is the midpoint between the buying and selling prices of a currency pair on the global foreign exchange market. It is the rate banks use when trading with each other. Google, XE.com, and most financial news sites display this rate because it represents the theoretical "fair" value of a currency at any given moment. However, it is not a rate that individuals can access directly — it is essentially the wholesale price of currency that financial institutions charge each other.
How Providers Make Money on Exchange Rates
When you use a bank or money transfer service, the provider buys currency at (or close to) the mid-market rate and sells it to you at a worse rate. The difference between the two rates is called the exchange rate spread or markup, and it is how providers make part of their profit. For example, if the mid-market USD to NGN rate is 1,600 and a provider offers you 1,540, they are applying a 3.75% markup. On a $1,000 transfer, that difference equals 60,000 naira that stays with the provider rather than going to your recipient.
How Big Is the Gap Typically?
The gap between the mid-market rate and the rate you receive varies dramatically by provider type. Traditional-bank FX pricing can include both an exchange-rate margin and transfer fees, which vary by institution and transaction. Money-transfer providers can apply different exchange-rate margins and fees that vary by corridor, amount and time. Specialist online transfer services use different pricing models, so compare the current recipient outcome rather than relying on a fixed markup range. Wise is notable for using the actual mid-market rate with a separate, transparent fee — making the gap very small compared to banks. The difference between provider outcomes can be meaningful and changes by corridor, amount and current pricing.
A Zero-Fee Claim Can Still Carry FX Cost
Some providers advertise zero fees for sending money to Nigeria, Ghana, Kenya, and other African countries. While they genuinely charge no separate fee, they still make money through the exchange rate markup. A zero-fee provider applying a 2% rate markup is more expensive than a provider charging a $3 fee and using a rate 0.5% from mid-market. The only reliable comparison is the total local currency your recipient actually receives — which accounts for both fees and the rate markup. AfriConvert compares available provider outcomes using the latest data available for the selected corridor.
How to Get Closer to the Google Rate
The best way to minimize the gap between Google's rate and what you actually receive is to use a provider that explicitly uses the mid-market rate with a transparent fee (like Wise) or to compare multiple providers on AfriConvert to find which delivers the most local currency for your specific amount. Avoid using your bank for international transfers — the markup is almost always the highest. For African corridors specifically, providers like Wise, LemFi, TapTap Send, Remitly, and Sendwave compete aggressively and often deliver rates much closer to mid-market than traditional services.
Why AfriConvert Shows Different Rates from Google
AfriConvert displays two types of rates: the mid-market reference rate (which is close to what Google shows) and each provider's actual live rate. The provider rate is what your recipient will actually receive. By comparing these side by side, AfriConvert makes the true cost of each provider transparent. The percentage difference between the mid-market rate and a provider's rate is effectively the exchange rate cost of using that provider. Add any transfer fees to that cost and you have the full picture of what each transfer actually costs.
