AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
The margin is the gap between the rate a provider gives you and the mid-market rate at the same moment, divided by the mid-market rate. If the mid-market rate is 110 naira per cedi and you are offered 106.70, the margin is 3%: on GHS 2,000 the recipient gets ₦6,600 less than a mid-market conversion would give (labelled example, not a real quote). Add any separate fee to find the true cost.
Many transfer services advertise a low or zero fee from Ghana to Nigeria. The cost does not disappear; much of it sits in the exchange rate. Eversend's Ghana page, for instance, says its rates "include our commission". Working out that cost takes one number you can find yourself and two minutes of arithmetic.
What the mid-market rate is
The mid-market rate is the midpoint between the price at which the market buys and sells a currency at a given moment. It is the reference rate you see on currency converters and financial news sites. No retail customer is usually given it exactly; it is the benchmark you measure a quote against. Because GHS/NGN is a thinly traded pair, some converters calculate it through US dollars, so the figure can differ slightly between sites. Use the same site each time you compare.
The formula
- Margin (%)
- (mid-market rate minus your rate) divided by mid-market rate, times 100
- Margin in naira
- amount in cedis converted at mid-market, minus amount the recipient actually receives
- Total cost
- margin in naira plus any separate fee, converted to naira at mid-market
Worked example
Example only. These figures are invented for the sum; they are not anyone's quote.
| Item | Figure |
|---|---|
| Amount sent | GHS 2,000 |
| Mid-market rate at that moment (example) | 1 GHS = 110.00 NGN |
| Value at mid-market | ₦220,000 |
| Provider's rate (example) | 1 GHS = 106.70 NGN |
| Recipient receives | ₦213,400 |
| Margin in naira | ₦6,600 |
| Margin as a percentage | 3.3 ÷ 110 = 3.0% |
| Separate fee (example) | GHS 15 = ₦1,650 at mid-market |
| Total cost | ₦8,250, or 3.75% of ₦220,000 |
The check: 2,000 × 110 = 220,000; 2,000 × 106.70 = 213,400; the difference is 6,600. The fee of GHS 15 × 110 = 1,650. Adding the two gives 8,250, and 8,250 ÷ 220,000 = 0.0375.
Comparing two quotes the right way
Compare what lands in Nigeria, not the fee. Two invented quotes for the same GHS 2,000, taken at the same moment:
- Quote A (example): fee GHS 25 deducted from the amount, rate 107.80. 1,975 × 107.80 = ₦212,905 received.
- Quote B (example): no fee, rate 106.50. 2,000 × 106.50 = ₦213,000 received.
Quote B, with the lower rate, delivers ₦95 more because it charges no fee. On a different amount the answer can flip, which is why the only fair comparison is the naira figure received for your actual amount, on the same day.
What moves the margin
- Route: a bank paying through PAPSS converts cedis to naira directly; other routes may convert through US dollars, and each conversion can carry its own spread. See our PAPSS guide.
- Amount: some providers set different rates for different amounts.
- Funding and payout method: MoMo, bank or card funding and bank or cash payout can be priced differently.
- Promotions: a first-transfer rate may not apply to the next one.
- Time: quotes are usually valid for a short time; a rate seen in the morning may not be the rate at payment.
What to check first
- Note the mid-market GHS/NGN rate from one converter at the moment you check.
- Get each provider's quote for your exact amount, showing cedis debited and naira received.
- Work out the margin and add any fee.
- Choose on the naira received, then check the provider is licensed and pays the account type your recipient has.
Reading a quote that hides the rate
Some screens show only "you send GHS 2,000, they receive ₦213,400" and no rate. You can recover the rate yourself: divide the naira received by the cedis converted. In the example, 213,400 ÷ 2,000 = 106.70. If a fee was taken out of the cedis first, divide by the amount actually converted, not the amount you paid. Once you have the effective rate, the formula above works the same way.
Keep a record
If you send regularly, note the date, amount, mid-market rate, rate given, fee and naira received for each transfer. After a few months you will see which routes cost you least for the amounts you usually send, and whether a promotional rate has quietly ended. A screenshot of each quote is enough evidence if the amount received ever differs from what you were shown.
For the same check on transfers from other countries, see FX margins on transfers to Nigeria.
Where Pryme fits
When you convert between currencies in a Pryme account with Swap, the rate is shown first and the fee on its own line, and nothing happens until you approve, so the comparison above can be done on the screen.
Questions people ask
How do I calculate the exchange margin on a cedi to naira transfer?
Subtract the provider's rate from the mid-market rate, divide by the mid-market rate and multiply by 100. Add any separate fee for the total cost.
Why is my cedi to naira rate lower than Google's?
Converters show the mid-market rate. Providers add a margin to it, and some say so: Eversend states its rates include its commission.
Is zero fee from Ghana to Nigeria really free?
Not necessarily. The cost may sit in the rate. Compare the naira received for the same amount at the same time.
What is a normal cedi to naira margin?
Providers do not publish standard margins. Measure each quote yourself against the mid-market rate on the day.
