M-Pesa vs Airtel Money: merchant fees compared in Nairobi (2026)

The verdict in three sentences

For a Nairobi merchant, M-Pesa Till is usually cheapest on collection (about 0.5 %, capped at KES 200 per transaction) while Airtel Money sits closer to 1.5 % with T+2 settlement versus M-Pesa's faster payout. But the headline rate hides the real cost: you must add withdrawal/cash-out fees, settlement delays and the choice between Buy Goods (Till) and Paybill. Below a KES 3,500 (~15,000 FCFA) ticket the M-Pesa cap makes it dramatically cheaper; above it, the flat KES 200 ceiling keeps large baskets almost free.

Real fees by ticket band

The nominal rate never tells the whole story. A merchant taking many small baskets and sweeping the balance weekly pays mostly in cash-out and locked-up cash. Here are the 2026 orders of magnitude seen in Nairobi.

On a KES 5,000 ticket, M-Pesa caps the fee at KES 200 (effective 4 % on that basket would be wrong — the cap makes it exactly KES 200), while Airtel takes ~KES 75. The picture flips entirely depending on ticket size.

The break-even point by ticket size

The break-even depends on your average basket. Here is the estimated monthly cost for 400 transactions, adding collection and cash-out (2026 order of magnitude).

The KES 200 cap is the whole game: for very large tickets M-Pesa becomes almost free proportionally, while Airtel's percentage keeps climbing. For mid-size tickets around KES 5,000–8,000, Airtel can briefly win before the cap kicks in for you.

Mini case study

Brian runs a fashion boutique in Nairobi. He takes 380 transactions a month, average ticket KES 6,000, i.e. KES 2,280,000 turnover. On Airtel Money at 1.6 % all-in he pays KES 36,480 monthly. Switching to M-Pesa Buy Goods, each KES 6,000 ticket costs the KES 200 cap only if it exceeds the cap threshold — at 0.5 % a KES 6,000 basket is KES 30, well under the cap, so he pays about KES 11,400 total. Monthly saving: KES 25,080, roughly KES 300,000 per year — enough to fund a local ad campaign. The trade-off: he must weigh Paybill vs Till for reconciliation clarity.

FAQ

Is M-Pesa really cheaper than Airtel Money in Kenya?

On small and large tickets, yes: 0.5 % capped at KES 200 beats a flat 1.5 %. On a KES 1.5M monthly volume the gap can top KES 8,000. It only reverses in a narrow mid-ticket band before the cap applies.

What is the merchant transaction limit?

Both wallets typically cap a standard merchant account near KES 500,000 per day. Beyond that you need an enhanced merchant profile with KYC documents, which unlocks higher ceilings.

Is Airtel's T+2 settlement a problem?

For most shops, not really — funds in two days is still workable. It becomes sensitive if you restock daily and need cash immediately available, where M-Pesa's faster payout wins.

Should I use Till (Buy Goods) or Paybill?

Buy Goods (Till) is simpler for a physical shop; Paybill suits invoicing with account references and easier reconciliation. Many merchants run both and route customers by use case.

How do I cut cash-out fees?

Batch your withdrawals: one weekly sweep of KES 500,000 costs less than five fragmented ones. A scheduled bank transfer is usually cheaper than an agent cash withdrawal.
