The verdict in three sentences
On merchant fees in Tanzania, one wallet plays simplicity (a capped ~1%) while the other defends tiers that climb up to 1.5% depending on the amount. For a merchant with 4,000,000 FCFA in monthly volume, the fee gap can reach 400,000 FCFA per year. But the incumbent keeps the advantage of a huge user base and higher account limits: the right choice is often both.
The fee tiers side by side
Here is a 2026 estimate (order of magnitude) of merchant fees applied at collection, before volume negotiation.
| Amount collected | Airtel (~1% capped) | M-Pesa (tiered) |
|---|---|---|
| 1,000 FCFA | 10 FCFA | 15 to 25 FCFA |
| 5,000 FCFA | 50 FCFA | 60 to 75 FCFA |
| 15,000 FCFA | 150 FCFA | 200 to 225 FCFA |
| 50,000 FCFA | 500 FCFA | 600 to 750 FCFA |
| 100,000 FCFA | ~1,000 FCFA (cap) | 1,200 to 1,500 FCFA |
| Average effective rate | ~1.0% | ~1.3 to 1.5% |
The difference looks tiny per transaction, but it compounds. Across thousands of transactions, every ten FCFA of gap becomes a meaningful cost line.
Settlement, limits and API cost
Fees are not the only criterion: settlement delay and account caps weigh on cash flow.
| Criterion | Airtel Money | M-Pesa |
|---|---|---|
| Average merchant fee | ~1.0% | ~1.3 to 1.5% |
| Settlement | 24 to 48 h | 48 to 72 h |
| API integration cost | low / free | low, partner-dependent |
| Merchant account cap | high | very high |
| User base | strong and growing | very large, incumbent |
| QR / payment link | yes | yes |
Airtel wins on cost and settlement speed; M-Pesa wins on caps and historical penetration. A checkout offering both captures the most customers at the best average cost.

Fatou runs an online shop with 4,000,000 FCFA in monthly volume, average basket 20,000 FCFA (200 transactions/month). Collecting everything on M-Pesa at ~1.4%, she pays 56,000 FCFA/month, or 672,000 FCFA/year. By routing 70% of volume through Airtel (~1%) and 30% through M-Pesa (~1.4%), her average rate falls to ~1.12%, or 44,800 FCFA/month: 11,200 FCFA saved per month, roughly 134,000 FCFA per year, without losing a single customer since both options stay available.
FAQ
Is Airtel Money always cheaper than M-Pesa?
On the pure fee, generally yes: ~1% capped versus 1.3 to 1.5% tiered. But M-Pesa offers higher account caps and a huge incumbent base, which matters for certain customer profiles.
How much does a merchant save by combining both?
For 4,000,000 FCFA/month, routing most volume through Airtel while keeping M-Pesa can save on the order of 130,000 to 400,000 FCFA per year depending on the mix, without cutting customer coverage.
Is M-Pesa's slower settlement a problem?
A 48-72 h payout versus 24-48 h weighs on cash flow if your margins are tight. For a fast-turnover business, a two-to-three day gap can matter.
Do I need a separate merchant account for each?
Usually yes, but a unified aggregator spares you two integrations: one checkout routes to Airtel or M-Pesa based on the customer's choice, with centralized reconciliation.
