Executive Summary
-
•
The Golden Rule: Your daily budget should be at least 5x your Target CPA (Cost Per Acquisition).
-
•
Lebanon Advantage: CPMs in Lebanon are approx. $3.00 - $5.00, compared to $15.00+ in UAE. Your money goes 3x further.

Action: Choose a test budget from your margins, expected acquisition cost, and the number of outcomes needed for a decision.
A useful ad budget connects the business goal to unit economics and the amount of campaign evidence needed. It is a planning decision, not one universal daily number.
The Reverse Engineering Formula
Do not choose a budget in isolation. Start with the outcome you want, your margins, expected conversion rate, and the amount of data needed to judge the test responsibly.
The Equation
Daily Budget = (Revenue Goal ÷ 30) ÷ Target ROAS
Example: You want $10,000/month revenue. Your Target ROAS is 4.0.
($10,000 ÷ 30) ÷ 4 = $83.33/day
Why 5x CPA Matters
Meta has historically used roughly 50 optimization events in seven days as a learning-phase reference, but delivery can still improve without hitting that number. Use it as context for data volume, not as a universal spending rule.
The Math: $10 CPA x 50 events / 7 days = $71/day minimum spend for optimal stability.
How the Lebanon Market Changes the Budget
Lebanon campaign costs can differ from Gulf and US markets, but they also vary by objective, audience, season, placement, and creative. Treat market ranges as context, not a promise of what your account will achieve.
| Metric | Lebanon | UAE / KSA | USA |
|---|---|---|---|
| CPM (Cost per 1k Impressions) | $3.00 - $5.00 | $12.00 - $18.00 | $25.00+ |
| CTR (Click Through Rate) | 1.5% - 2.5% | 0.8% - 1.2% | 0.9% |
- Lower CPMs: You can reach 1,000 people for ~$4.00. In Dubai, that costs $15.00. This means your "Testing Budget" can be lower in Lebanon.
- Cash Economy: You must account for "Cash on Delivery" (COD) refusal rates. If 20% of orders refuse delivery, your ad budget must account for that waste. We recommend adding a 15% buffer to your CPA targets.
Scenario Analysis: Low vs. High Budget
We often get asked: "Can I start with $5/day?" The honest answer is no. Here is why.
Scenario A: The $5/day Strategy (The Trap)
At $150 per month, a campaign may generate too few meaningful actions to separate a pattern from normal variation. The exact outcome depends on your auction costs and conversion rate.
Scenario B: The $30/day Strategy (The Minimum)
At $900 per month, the same business may collect more useful evidence, but a higher budget does not automatically make the result statistically significant or justify doubling spend. Scale only after checking sales quality, margin, and attribution.
Seasonality Factors in Lebanon
Ad costs are not static. In Lebanon, they fluctuate wildly based on holidays and events.
- Ramadan: CPMs rise by 30-40% due to high competition from food & beverage brands.
- Black Friday (Nov): CPMs double. If you don't have a strong offer, pause your ads.
- Summer (July/Aug): Returning visitors and seasonal behavior may change demand in some categories. Confirm the effect in your own sales and auction data.
Testing Budget vs. Scaling Budget
It can help to distinguish a testing budget, used to learn, from a scaling budget, used on better-supported opportunities. The right split depends on how mature the account and offer are.
For a Lebanese e-commerce brand starting out, we recommend:
- Week 1: $30/day (Testing Creatives in ABO). Goal: Find 1 winning creative.
- Week 2: $50/day (Move winner to CBO). Goal: Verify stability.
- Week 3: Increase spend only when conversion quality, margin, and attribution remain acceptable; use increments appropriate to the account.
