Most ecommerce businesses spend $500 to $5,000 per month on Facebook ads. That is the honest answer to what people actually spend. It is not the same as the answer to what you should spend, and the gap between those two numbers is where most budgets quietly fail.
Facebook ad spend clusters into three broad tiers. These are observed spend levels, not recommendations — the difference matters, and we will come back to it.
If you take one thing from this table, make it the third column. Spend levels are easy to copy. What that spend can actually accomplish is the part that decides whether the money works.
The figures below come from Triple Whale's analysis of roughly 35,000 ecommerce brands across the full 2025 calendar year. It is the largest publicly available ecommerce-specific dataset on Meta ad costs, which is why we use it rather than the all-industry averages most guides quote.
The story in that table is the first row. CPM rose 20% while CPA rose 1%. Impressions got a fifth more expensive and acquisition costs barely moved, which means creative and conversion rates absorbed the increase. Brands that improved their creative held their CPA flat. Brands that did not paid the full 20%.
CPM increased in all 15 industries measured. There were no exceptions. Auction inflation is not something you can pick a vertical to avoid.
Health and wellness is the vertical worth studying. It posted the highest CTR of any category at 2.70% and simultaneously the lowest ROAS at 1.50, on the highest CPM at $20.70. People click and then do not buy. If you sell supplements, that is your entire strategic problem in one line.
Applying the averages above to common monthly budgets. This is arithmetic, not a forecast — but it is the arithmetic Meta is working with when it spends your money.
Two things stand out. First, a $500 month produces roughly 12 orders — not enough data to conclude anything about which creative or audience worked. Second, the implied ROAS is 1.77 at every level, because ratios do not improve just because you spend more. Scale amplifies your economics. It does not fix them.
Here is the part that changes how you should read every other number on this page.
Meta's delivery system needs roughly 50 conversions per ad set per week to exit the learning phase. Below that threshold the algorithm never finishes optimising, and your cost per result stays volatile and inflated. This gives a hard formula for the real minimum:
(Your expected CPA × 50) ÷ 7 = minimum daily budget, per ad set
Run the ecommerce CPAs from the benchmark table through it and the picture is uncomfortable.
The average ecommerce brand needs $8,184 a month per ad set for that ad set to optimise properly. The figure most cost guides recommend as a starting budget is $500. That is a 16-fold gap between the advice and the arithmetic.
And note the unit: per ad set, not per campaign. A tidy-looking structure with one prospecting ad set, one lookalike and one retargeting ad set does not need $8,000. It needs about $24,000. This is the single most common reason a well-built account underperforms: the structure is correct and the budget cannot support it.
For most brands it is out of reach, and that is fine — provided you stop pretending the budget will behave like a bigger one. Four adjustments that actually work:
Separate from what works, these are the technical floors Meta enforces before a campaign will run at all.
Treat these as the point at which the ad is permitted to run, not the point at which it is likely to work. The distance between $300 a month and $8,184 a month is the distance between a campaign that serves and a campaign that optimises.
If you want a number: $1,500 to $3,000 a month is a defensible starting point for a DTC brand that wants real data within a quarter. Below $1,000 you are buying impressions, not learning. Above $8,000 per ad set you are giving the algorithm what it actually needs.
And the uncomfortable implication of the 20% CPM rise: media costs are no longer the lever. Creative is. The brands that held CPA flat last year did it by making better ads, not by finding cheaper impressions.
If you would rather not carry that creative load in-house, our ecommerce marketing agency runs strategy, creative and paid media for DTC brands on Shopify, priced against outcomes rather than hours. If you would rather do it yourself, start by studying what already works — our guide to the Meta Ad Library shows how to find the ads your competitors have been running long enough to prove they are profitable.
