The verdict in three sentences
In Kampala in 2026, the merchant looks at the advertised merchant fee (1-1.8 %) and thinks they know their collection cost. They forget the cash-out: converting the wallet balance into cash costs 1 to 3 % more per tier, with agent limits and a penalty from the 5th monthly withdrawal. The result: whoever withdraws everything actually pays 3 to 5 % of revenue.
The cost nobody advertises
The merchant fee is the visible part. The cash-out is the part that bleeds, especially when you withdraw small amounts several times a month.
| Item | 2026 cost (Uganda) | Detail |
|---|---|---|
| Merchant collection fee | 1-1.8 % | charged on receipt |
| MTN/Airtel withdrawal | 1-3 % + tax | tiered: small amounts = higher % |
| Agent withdrawal limit | ~5,000,000 UGX/day | forces splitting |
| Penalty beyond 4 withdrawals/month | +0.3-0.8 % | higher fees |
| Cumulative cost (systematic withdrawal) | 3-5 % of revenue | collection + cash-out |
A merchant who keeps the balance in-wallet to pay suppliers directly sidesteps much of the cash-out.
Keep the balance vs withdraw everything
The structural decision: treat the wallet as a till (pay suppliers, salaries, bills in mobile money) or systematically empty it into cash.
| Strategy | Total collection cost | Liquidity | When to choose |
|---|---|---|---|
| Systematic withdrawal | 3-5 % of revenue | Immediate cash | 100 % cash suppliers |
| Balance kept in wallet | 1-1.8 % of revenue | Wallet | Suppliers accept MoMo |
| Mixed (50/50) | ~2.5-3 % | Balanced | Most common case |

For comparison in Lomé, Moov and MTN charge withdrawal at 1-2.5 % per tier, with an agent cap around 200,000-500,000 FCFA/day — same logic, same leakage.
Mini case study
Kodjo, a hardware merchant in Kampala, collects 4,000,000 FCFA/month in mobile money. He withdrew everything: 1.5 % merchant fee + 2 % average cash-out + penalties = ~3.8 %, or 152,000 FCFA/month. By paying 60 % of his suppliers directly in-wallet, he only cashes out 40 %: his cost drops to ~2.3 %, or 92,000 FCFA/month. Estimated saving: 60,000 FCFA/month, or 720,000 FCFA/year.
FAQ
Is cash-out really pricier than the merchant fee? Often yes: the merchant fee runs 1-1.8 %, but cash-out split into small amounts can exceed 3 % per withdrawal, especially beyond 4 withdrawals/month.
How do I reduce cash-out without changing my business? By paying as many costs as possible (suppliers, salaries, bills) directly from the wallet. Every unit not withdrawn saves 1 to 3 %.
Do agent limits block big merchants? Yes: with a cap around 5,000,000 UGX/day per agent, withdrawing large sums forces splitting across days or agents, multiplying fees.
Does an e-commerce site change the math? It doesn't remove cash-out, but a back-office tracking each wallet lets you decide what to keep and what to withdraw — and pay cash-out only on what's strictly needed.
