The verdict in three sentences
In East Africa, Meta Ads offers a low CPM of 1 to 4 USD and a CPC of 0.03 to 0.15 USD, making acquisition very affordable. The real challenge isn't the cost per click but tracking: M-Pesa and mobile money payments don't flow back to the pixel automatically, so you measure manually. The winning 2026 campaign routes traffic to WhatsApp click-to-chat, targets a ROAS of 3 to 5x, and starts with a test budget of 100 to 200 EUR/month.
The real cost of acquisition in 2026
A low CPM doesn't guarantee profitability: it all depends on conversion rate and basket size. Here are the Meta Ads benchmarks for East Africa (2026 order of magnitude).
| Metric | 2026 range | Comment |
|---|---|---|
| CPM (1000 impressions) | 1 - 4 USD | Among the world's lowest |
| CPC | 0.03 - 0.15 USD | Abundant traffic |
| Cost per WhatsApp click | 0.05 - 0.25 USD | Best converting format |
| Conversion via WhatsApp | 5 - 15% | Vs 1-3% direct site |
| Target ROAS | 3 - 5x | Break-even ~2x |
WhatsApp click-to-chat converts 3 to 5 times better than sending traffic straight to a site, because the prospect asks questions and gets reassured before buying.
How much to invest and what revenue to expect
Budget isn't guessed, it's calculated backward from the target ROAS. Here are scenarios for an average basket of 2,000 KES and a 4x ROAS.
| Monthly budget | Expected revenue (ROAS 4x) | Estimated orders | Phase |
|---|---|---|---|
| 100 EUR (~14,000 KES) | ~56,000 KES | ~28 | Test |
| 300 EUR (~42,000 KES) | ~168,000 KES | ~84 | Ramp-up |
| 600 EUR (~84,000 KES) | ~336,000 KES | ~168 | Scale |
| 1,000 EUR (~140,000 KES) | ~560,000 KES | ~280 | Scale + |
Golden rule: never raise the budget before stabilising a ROAS above 3x over at least 2 to 3 weeks of testing.
Mini case study
Kevin launches a phone-accessories shop in Nairobi. He starts with 150 EUR/month (about 21,000 KES) on WhatsApp click-to-chat campaigns. Average basket 2,000 KES, WhatsApp conversion rate 10%.
His cost per WhatsApp click is 0.12 USD; with 150 EUR he generates about 1,350 clicks, so 135 potential orders at 10% conversion. Even keeping 40 real conversions after filtering, he reaches 80,000 KES of revenue for 21,000 KES spent, a ROAS of nearly 4x in his first month. He can then safely move to 300 EUR.

FAQ
Why is mobile money tracking a problem?
The Meta pixel receives no purchase event when payment happens via M-Pesa or mobile money outside the browser. So you must log conversions manually or use a homemade tracking link.
Should I send traffic to a site or to WhatsApp?
In 2026, WhatsApp click-to-chat converts 3 to 5 times better, because the buyer asks questions before paying. Reserve site traffic for already well-optimised catalogues.
What's the minimum budget to test seriously?
Expect 100 to 200 EUR over 2 to 3 weeks: that's the minimum for the algorithm to exit its learning phase and give reliable data.
What ROAS should I target to be profitable?
Break-even is around 2x depending on your margin; aim for 3 to 5x to make real profit after logistics costs and returns.
How long before I see results?
First signals appear in 5 to 7 days, but wait 2 to 3 weeks before judging and raising the budget, so learning can stabilise.
