The verdict in three sentences
When a merchant reads "1% fee", they only see collection: on top come payout, FX, cash-out and sometimes a local mobile money tax. Added up, these invisible costs push the real bill 30 to 50% above the nominal rate. Understanding each layer lets you recover several margin points.
The five cost layers
Collection (charging the customer) runs about 1 to 2%. Payout (moving funds to your account or a seller's) adds 0.5 to 1%. If you collect in foreign currency, FX takes 2 to 3%. Cashing out costs roughly 1.5% more. Finally, some countries tax mobile money: 1% in Ghana, 0.5% in Uganda (2026 orders of magnitude).
| Cost layer | Typical 2026 rate | Trigger | Avoidable? |
|---|---|---|---|
| Collection | 1-2% | every charge | no |
| Payout | 0.5-1% | transfer to account/seller | partial (batch) |
| FX | 2-3% | collecting in foreign currency | yes (bill locally) |
| Cash-out | ~1.5% | withdrawing cash | yes (stay digital) |
| Mobile money tax | 0.5-1% (GH/UG) | by country | no (legal) |
| Reversal fee | variable | refund/dispute | yes (fewer disputes) |
Total cost per KSh 100,000 collected
Take a merchant collecting KSh 100,000 and see what they truly keep by behavior. Keeping funds digital and billing in local currency avoids the heaviest layers.
| Scenario | Collection | Payout | FX | Cash-out | Net kept |
|---|---|---|---|---|---|
| Optimal (digital, local) | 1,000 | 500 | 0 | 0 | KSh 98,500 |
| Average (payout + little cash) | 1,500 | 1,000 | 0 | 750 | KSh 96,750 |
| Costly (FX + cash) | 2,000 | 1,000 | 2,500 | 1,500 | KSh 93,000 |
| Worst (FX + cash + tax) | 2,000 | 1,000 | 3,000 | 1,500 | KSh 91,500 |
Between optimal and worst, the gap reaches KSh 7,000 per 100,000 collected, or 7% of margin gone — hence "30 to 50% above the advertised rate" on processing cost.

Mini case study
James, a restaurateur in Nairobi, collects KSh 4,000,000/month. He withdrew everything in cash and sometimes accepted foreign-currency payments from passing customers. His real cost hit about 5.5%, or KSh 220,000/month. By billing consistently in KSh, keeping 70% of funds digital and batching payouts, he dropped to 2.2%, or KSh 88,000/month. Saving: nearly KSh 132,000/month, without changing provider.
FAQ
Why does my real cost exceed the advertised rate? Because the advertised rate only covers collection. Payout, FX, cash-out and taxes stack up and push total cost 30-50% above nominal.
How do I reduce FX fees? Bill in local currency whenever possible. FX takes 2-3% per conversion: avoiding it is the fastest lever for local customers.
Is cash-out really expensive? Yes, about 1.5% per withdrawal. Keeping funds digital to pay suppliers and salaries avoids this layer almost entirely.
Which countries tax mobile money? In 2026, Ghana applies about 1% and Uganda about 0.5% (orders of magnitude). Kenya's picture differs; always price the local tax context into your rates.
Does batching payouts make a difference? Yes. A weekly batched payout instead of daily reduces the number of operations charged at 0.5-1%, notably lightening the bill on high volumes.
