2 to 3 times your normal daily Meta ad spend, ramped there gradually rather than jumped into. That’s what one agency’s own Black Friday playbook recommends for Cyber Week (SciGrowth, Meta Ads Black Friday Playbook), and similar multipliers circulate everywhere this time of year. None of them are a budget on their own. 2 to 3x is a multiplier with no dollar sign attached, and nobody handing it to you says what it actually looks like in AU dollars for your account, or what happens to the fee you are already paying on top of it.
If you are an Australian Shopify store spending $2,500 a month on Meta, that range means one thing. If you are spending $6,000 a month because the account has scaled past that already, it means something close to three times as much in real dollars. Nobody selling the multiplier tells you which number is yours.
What the multiplier doesn’t tell you
The advice itself is not wrong. Scale in steps rather than one jump, protect the retargeting layer as costs rise, hold spend through the pre-Cyber-Week dip rather than cutting it: all reasonable, all repeated across most of what is written on this. What is missing is a starting baseline that means anything to an AU account, and an honest answer to whether your agency’s own fee moves when your ad spend does.
What’s actually pushing the cost up this quarter
Two numbers explain where the multiplier comes from, and neither is a seasonal guess. Meta’s own fourth-quarter and full-year 2025 results put the average price per ad up 6% year-on-year for Q4 2025, and 9% for the full year (Meta, Fourth Quarter and Full Year 2025 Results). That is a company-wide figure across every country, placement and advertiser on the platform, not a Black Friday number and not an Australian one specifically, which means it most likely understates what a single competitive AU eCommerce category sees in a single peak week rather than overstating it.
The baseline that gets multiplied already runs high here. Lebesgue’s 2026 country benchmark puts the Australian Facebook ad CPM at roughly $11.63, in its highest cost tier globally, before any BFCM-specific bidding even starts (Lebesgue, Facebook Ads CPM by Country, 2026). Apply that 2 to 3x seasonal lift to an already-expensive baseline and the gap between “spend a bit more” and the real number widens fast.
Worth saying plainly: not every data source agrees Meta CPMs climb evenly across the whole run-up to Black Friday. Some measured same-store data shows costs flat, even lower, through most of late November before spiking hard on the one or two peak days themselves, rather than rising steadily across the month. That disagreement hasn’t been settled anywhere in the ad-tech data the industry publishes, and it’s one more reason a flat “2 to 3x for the month” instruction is the wrong shape of advice. The real decision is how much room to leave for the specific days that spike, not an even markup across November.
Three real AU numbers, not a multiplier
Here is what that looks like in dollars, using the ad-spend minimums behind three real account sizes and applying that playbook’s 2 to 3x range to the seven days most AU retailers treat as Cyber Week this year (27 November to 3 December). These are illustrative applications of one named recommendation to real spend levels, not a forecast and not a guarantee. Your account’s actual number depends on your category, your audience size, and what you were already spending.
A $2,500/mo account running at roughly $83 a day normally is looking at an extra $580 to $1,160 pulled into that single week if it holds the full range, on top of normal spend. A $5,000/mo account running near $167 a day sits at an extra $1,170 to $2,330. A $6,000/mo account at the top end sits at an extra $1,400 to $2,800. None of that is a retainer fee moving. It is the ad-spend line, billed directly to your own ad account, doing what that recommendation says it will do.
Which end of the range is actually yours
The 2 to 3x range isn’t a shrug. Where your account sits on it maps to how the account is already built heading into November, not to how much you feel like spending. Standard pacing practice for the period looks like this: hold spend at or slightly above October levels through the pre-Cyber-Week dip rather than cutting into it, because that dip is the common and expensive mistake; step up in planned increases through Cyber Week itself, shifting a bigger share toward retargeting than usual, since it already knows your brand and converts at a lower cost than cold prospecting into a more expensive feed; then step spend back down in stages after Cyber Monday instead of switching it off.
If you don’t know whether your account’s real BFCM number looks like the $580 scenario or the $2,800 one, that’s worth a second set of eyes before November, not during it.
An account that has been testing creative since September and already has a built retargeting pool can move toward the top of the range with real confidence, because the extra dollars have somewhere efficient to land. An account still running on cold prospecting alone heading into November is better served near the bottom of it. More spend on an account with nothing warm to retarget mostly just buys more expensive cold traffic at the worst possible week to be paying for it.
The number that doesn’t move: your fee
Here is the part the multiplier conversation always skips. A flat monthly fee doesn’t look at your ad account before it’s billed. Whether you spend $2,500 this month or $4,500 because you held steady through the dip and then stepped up for Cyber Week, the fee stays the same dollar figure either way under HC’s tiers (see pricing for the current bands). A percentage-of-spend deal moves with you instead: scale ad spend for BFCM and the fee for that same work scales automatically, the exact dynamic this blog worked through at three price points in Flat Fee vs Percentage of Ad Spend (AU). Neither structure is dishonest. But only one of them means your BFCM decision is purely a media-spend decision, not also a “does this cost more in fees” decision.
Your ad budget needs to flex for Black Friday. A flat monthly fee, by design, does not.
The budget only matters if the account is already warm
None of the dollar figures above do much good if the account hits Cyber Week cold. When to Start BFCM Meta Ads in Australia already covers the timeline: the 60-90 day prep window, the warm-audience build through October, the reason an account still running June’s three ads in October is not early, it’s already behind. The budget question and the timing question are two different problems, and solving one without the other wastes the money either way. Extra spend poured into an account with no retargeting pool built yet buys expensive cold traffic at peak CPMs. A perfectly-timed account with no extra budget just runs out of room to capture the demand it spent two months building.
What this actually means for your account
Work out which of the three tiers above sits closest to your real spend, apply that 2 to 3x range to your own number rather than ours, and check that figure against what you were already planning to spend in November. If there’s a wide gap between the two, that’s worth resolving now, not in the last week of the month. And if the honest answer is that nobody has checked whether the account’s creative and retargeting pool is actually ready to spend that extra money well, that is a question worth answering before a budget one.
A blog post can give you one agency’s range and the AU baseline. It can’t give you your account’s actual number, because that needs someone looking at the actual account. Book a free teardown and find out before Black Friday does.
