The verdict in three sentences
A payment's success rate varies enormously by method: from 95 % on the best STK-push wallets to 70 % on some card flows. The main failure causes are STK/USSD timeout, insufficient balance and 3DS abandonment. A few simple levers (T+1 retry, provider fallback, pre-fill) can recover 5 to 12 points of rate, worth hundreds of thousands on an average GMV.
Success-rate benchmark by method (2026)
The figures below are a 2026 order of magnitude observed on shops in Lagos, Nairobi and Accra. They depend on integration quality and audience.
| Method | Estimated success rate | Main failure cause | Average delay |
|---|---|---|---|
| M-Pesa STK push | 88 to 92 % | Timeout / PIN not entered | 10 to 45 s |
| Paystack cards | 85 to 95 % | 3DS failure / card declined | 5 to 30 s |
| Flutterwave cards | 82 to 92 % | 3DS / declined | 5 to 30 s |
| Airtel Money | 82 to 90 % | Timeout / cancel | 15 to 45 s |
| Bank transfer (NIP) | 90 to 96 % | Wrong reference | Instant |
The gap between bank transfer and USSD flows comes down to experience: a link or QR confirms in two taps, while a USSD flow forces manual entry under time pressure, hence the timeouts.
Optimization levers ranked by gain
Each lever has low implementation cost and a measurable gain. Here is the 2026 estimate.
| Lever | Estimated rate gain | Effort | Impact on 10 000 000 NGN GMV |
|---|---|---|---|
| Automatic T+1 retry | +3 to 6 pts | Low | +300 000 to 600 000 NGN |
| Provider fallback (offer another method) | +2 to 5 pts | Medium | +200 000 to 500 000 NGN |
| Pre-fill number / amount | +1 to 3 pts | Low | +100 000 to 300 000 NGN |
| Abandoned-cart nudge (SMS/WhatsApp) | +2 to 4 pts | Medium | +200 000 to 400 000 NGN |
| Longer timeout + clear message | +1 to 2 pts | Low | +100 000 to 200 000 NGN |
Combined, these levers can easily recover over 1 000 000 NGN per 10 000 000 NGN of GMV, without acquiring a single extra customer.
Mini case study
Ngozi runs an online shop in Lagos, 8 000 000 NGN monthly GMV, average success rate 83 %. She adds a T+1 retry by SMS and a fallback "pay with another method." Her rate rises to 91 % (+8 pts). On 8 000 000 NGN, that is about 640 000 NGN of revenue recovered each month that previously vanished in failed payments, for a one-off implementation cost.

FAQ
What is the average mobile money success rate?
Between 82 and 95 % by method: bank transfer and best STK flows are highest, older USSD flows lower due to timeouts.
Why do card payments fail more?
Because of 3DS failures and declines: the rate often drops to 70-85 %, versus 90 %+ for a local wallet.
Is T+1 retry worth the effort?
Yes: it's the best gain-per-effort lever, adding +3 to 6 points of rate for a low implementation cost.
How do I measure my success rate?
Track the ratio of completed payments to attempts in your dashboard. A clear dashboard is the prerequisite to any optimization.
How much can I recover?
On 10 000 000 NGN of GMV, gaining 10 points of success rate means 1 000 000 NGN recovered every month.
