The verdict in three sentences
In Kampala, MTN MoMo and Airtel Money are near-identical on headline rate (~1.5 % plus a small fixed component), so the deciding factors are subscriber reach and API quality. MTN MoMo offers the widest base and a mature Open API; Airtel Money is a strong complement to capture Airtel customers. Above UGX 20M/day, KYC ceilings usually force you to route across both.
Fees and ceilings by KYC tier
The figures below are 2026 estimates (order of magnitude) for a verified merchant account in Uganda.
| Wallet | Merchant fee (est.) | Daily cap (basic KYC) | Daily cap (full KYC) | USSD 3G fallback |
|---|---|---|---|---|
| MTN MoMo UG | ~1.5 % + fixed | UGX 5,000,000 | UGX 20,000,000 | Very reliable |
| Airtel Money UG | ~1.5 % | UGX 5,000,000 | UGX 20,000,000 | Reliable |
Both operators cap basic KYC at UGX 5,000,000/day: for a high-ticket store, full merchant KYC is essential.
The break-even by monthly volume
At what volume does the rate gap become material? Here is the comparative bite across three revenue levels.
| Monthly volume | MTN MoMo (1.5 %) | Airtel Money (1.5 %) | Gap/month |
|---|---|---|---|
| UGX 50,000,000 | UGX 750,000 | UGX 750,000 | ~UGX 0 |
| UGX 100,000,000 | UGX 1,500,000 | UGX 1,500,000 | ~UGX 0 |
| UGX 150,000,000 | UGX 2,250,000 | UGX 2,250,000 | fixed-fee driven |
With near-equal rates, the fixed per-transaction component and API reliability, not the percentage, decide the winner in Uganda.

Sarah, who runs a cosmetics store in Kampala, collects UGX 100,000,000/month via Airtel Money only. Because Airtel's fixed component adds up on many small orders, her effective rate is ~1.7 %, or UGX 1,700,000. By adding MTN MoMo for larger baskets and routing to minimize fixed fees, her blended rate falls to ~1.55 %, or UGX 1,550,000. Saving: UGX 150,000/month, about UGX 1,800,000/year, while capturing both networks.
