The verdict in three sentences
The processing rate your payment provider advertises represents only a fraction of what you actually pay each month. The real margin killers are invisible: a 2.5-4% FX markup on foreign-currency sales, payout fees per transfer, dispute fees of NGN 3,000-5,000, and VAT applied on the fees themselves. A merchant tracking only the headline rate underestimates the true cost of collecting by 30 to 60%.
The four fee layers nobody shows you
When a PSP advertises "1.5% per transaction," that is the bottom layer. Here is what actually stacks on top, as 2026 order-of-magnitude figures for West and Sub-Saharan African markets.
| Fee layer | 2026 range | Basis | On the brochure? |
|---|---|---|---|
| Transaction commission | 1.0 – 1.7% | Amount collected | Yes |
| FX markup | 2.5 – 4.0% | Foreign-currency sales | Rarely |
| Payout fee | NGN 100 – 500 | Per transfer | No |
| Dispute/chargeback fee | NGN 3,000 – 5,000 | Per dispute | No |
| VAT on fees | 7.5% | On total fees | No |
The FX markup is the most insidious. If you sell to a customer in euros or dollars and the PSP converts to naira, it applies a 2.5-4% spread against the interbank rate. For a shop doing 30% of its sales internationally, that spread outweighs the base commission.
What it really costs in a typical month
Take a merchant collecting NGN 5,000,000 per month, of which NGN 1,500,000 is in foreign currency, with 200 payouts and 4 disputes.
| Line item | Calculation | Monthly cost |
|---|---|---|
| Commission (1.5%) | 5,000,000 × 1.5% | NGN 75,000 |
| FX markup (3%) | 1,500,000 × 3% | NGN 45,000 |
| Payouts (200 × 250) | 200 transfers | NGN 50,000 |
| Disputes (4 × 4,000) | 4 cases | NGN 16,000 |
| VAT (7.5% on fees) | 186,000 × 7.5% | NGN 13,950 |
| Total | — | NGN 199,950 |

The effective rate is not 1.5% but 4.0% — nearly three times the headline. Over a year, the gap between perceived and real cost exceeds NGN 1,500,000.
Mini case study
Blessing runs a cosmetics shop in Lagos and sells 20% of her volume to the diaspora in the UK. She thought she paid 1.5% in fees. Breaking down three months of statements, she found the FX markup on her GBP sales cost her NGN 38,000 a month — more than her electricity bill. By moving her diaspora collections to a provider quoting interbank + 1.2%, she saves roughly NGN 27,000 a month, or NGN 324,000 a year reinvested in stock.
FAQ
Why is the FX markup so hard to spot? Because it never appears as a fee line: it is baked into the conversion rate applied. Always compare the PSP's rate to the day's interbank rate — the gap is your real cost, often 2.5 to 4%.
Are payout fees negotiable? Yes, above a certain volume. A merchant doing more than 300 transfers a month can often secure a flat rate or a tiered fee bringing the cost from NGN 250 down to under NGN 100 per payout.
Is VAT on fees recoverable? If you are VAT-registered and hold compliant invoices, the 7.5% VAT on payment fees is in principle deductible. Many small merchants never reclaim it for lack of a detailed PSP invoice.
How do I cut dispute fees? By documenting every order (delivery proof, customer confirmation) and responding within 48 hours. Keeping your dispute rate under 0.5% avoids penalties and account freezes.
