M-Pesa vs Airtel Money: The Real Merchant Fee Comparison in Nairobi (2026)

The verdict in three sentences

M-Pesa Till collects at 0.55 to 1.5 %, Airtel Money at 1 to 2 %: on transaction cost alone, M-Pesa usually wins in 2026. But the right choice depends on your average basket, your customer coverage and the settlement delay (24 to 72 h). The rule: M-Pesa to maximize margin, Airtel Money when your customers mostly use it and availability comes first.

The fee grids head to head

Merchant collection fees are what nibble your margin on every sale. Half a point of gap at high volume is hundreds of thousands of shillings a year.

These are 2026 order-of-magnitude figures to confirm against your merchant contract. A 0.5-point gap looks small, but it compounds on every transaction.

The switch table by basket size

At fixed rates, M-Pesa is always cheaper in percentage. What changes is the absolute amount saved by average basket and transaction count. (Figures shown in FCFA-equivalent for comparison.)

On 1,000 transactions/month at a 40,000 FCFA basket, the gap is 200,000 FCFA/month, or 2,400,000 FCFA/year. The question becomes: will your customers pay via M-Pesa? If yes, push M-Pesa by default and keep Airtel as backup.

Saving: 110,250 FCFA/month, or 1,323,000 FCFA/year, simply by offering M-Pesa by default at checkout.

FAQ

Is M-Pesa always cheaper? On the collection rate, usually: 0.55 to 1.5 % versus 1 to 2 %. But the right provider also depends on who uses what among your customers and your need for fast settlement.

Do transaction caps get in the way? Rarely for retail. For larger baskets you split the transaction or use a transfer, which stays marginal.

How long to get paid? Expect 24 to 48 h for M-Pesa and 48 to 72 h for Airtel on merchant settlement. It is a 2026 order of magnitude by contract.

Should I offer both? Yes. Offering M-Pesa and Airtel at checkout maximizes conversion: each customer pays with what they already have. You simply push M-Pesa by default for margin.

Does a 0.5-point gap really matter? Enormously at volume. On 1,000 transactions at 40,000 FCFA, that is 200,000 FCFA/month, 2,400,000 FCFA/year. The payment mix is an underrated margin lever.
