Search “how much should I spend on Meta ads” and you’ll get the same answer from every generic marketing blog: 10 to 30% of revenue. It’s not wrong. It’s also not useful if you’re an Australian Shopify founder trying to work out whether $2,500 a month buys you anything, or whether you need $6,000 before a real strategy is even possible.
The 10-30% rule also assumes you already have revenue to take a percentage of. If you’re pre-launch, or your Shopify store is doing $8k/month and trying to work out whether ads are even the right next move, “take 20% of revenue” tells you nothing useful. What actually matters is the number nobody publishes: what a flat management fee costs you as a percentage of ad spend, at every tier. That’s the arithmetic that tells you whether paying someone to run your account makes sense yet, or whether you’re better off fixing the account yourself first.
What Meta ads actually cost to run in Australia right now
Before the budget question, there’s the cost-per-click question. Australian Meta CPMs are running somewhere around $8-20 depending on your niche and creative, with CPCs typically $0.75-$2.50. Shopify’s own benchmark data sits inside that range too, though it’s a global average rather than an AU-specific figure. That’s not a number I control and it’s not one you control either. It’s the auction, and it moves with the season, your niche and how tired your creative is.
What you can control is your budget band, and that’s the more useful question to answer first. Under roughly $1,500-2,500/month, you don’t have enough volume for Meta’s algorithm to properly learn. You’re testing, not scaling. That’s the floor for meaningful data, not the floor for a management retainer. Those are two different floors, and mixing them up is where the “how much should I spend” advice usually goes wrong.
A quick worked example, because a range is easier to trust than a rule of thumb. At a $15 CPM, a $2,500/month budget buys roughly 166,000 impressions before a single sale happens. At $0.75-$2.50 CPC, that same budget buys somewhere between 1,000 and 3,300 clicks, depending on how tight your targeting is.
Whether that’s “enough” depends entirely on your conversion rate and average order value, not on the spend figure by itself. This is the calculation a management fee should be paying someone to actually watch, not a one-off you do at the start of the quarter and forget.
The real question: which spend band are you actually in
I price flat monthly, by your ad spend band, not by promises about results. Every tier is published. Here’s what each one actually costs you as a share of your ad spend:
- Under $2,500/month spend. A management retainer doesn’t make sense yet. The fee would be a bigger line item than the media it’s managing, so I won’t pitch it. This is where the $590 Ad Account Rescue belongs instead: Pixel and CAPI fixed, one campaign rebuilt properly, a 30-day read on what’s actually happening. One-time, not a retainer.
- $2,500-5,000/month spend. Account Foundation, $1,200/month. At the bottom of that band that’s 48% of spend; at the top of it, 24%. The fee shrinks as a share of budget as you grow inside the tier, which is the point of pricing it this way rather than charging a flat industry rate regardless of size.
- $5,000-6,000/month spend. Full Account Management, $2,000/month. 40% of spend at the floor, 33% at the ceiling.
- $6,000+/month spend. Peak Season & Catalogue, $3,000/month. This is an ascension tier for accounts already running at volume, not where a new store starts even if it happens to launch at $6k.

Nobody sells it this way, because tier-by-spend-band is a harder pitch than tier-by-promise. It means telling a founder spending $2,600/month that the fee is still going to feel heavy this quarter, instead of promising them a ROAS I can’t guarantee. But it’s the only version of “how much should I spend” that survives the follow-up question. “Why am I on this tier and not that one” gets an arithmetic answer, not a sales answer.
None of this comes with a results guarantee, and I won’t pretend otherwise. Nobody can honestly promise a ROAS number before they’ve seen your account, mine included. What I do commit to in writing is conduct: the account checked every single day, not once a month, and every change I make logged back to you in plain English within 7 days. If that doesn’t happen, the month is free. That’s a guarantee I actually control, which is more than most agencies offer on the outcome side either.
More spend doesn’t fix what spend didn’t break
Here’s the part the 10-30% rule never mentions: spend usually isn’t the problem. I’ve put $1,570 of my own money into Meta ads for one of my own brands and generated 32 leads at $49 CPL. Zero of them turned into a sale. The media buying worked. The algorithm did its job and the leads were real. What was broken was everything downstream of the click: the offer, the follow-up, the close. That’s the part I rebuilt, and it’s a completely different fix to “increase your daily budget.”
If your ads are generating clicks and leads but not sales, more spend just buys you more of the same leak, faster. Before you touch the budget slider, work out whether the problem is upstream (nobody’s seeing the ad) or downstream (people click and nothing converts). The eCommerce-specific mechanics are different again from a generic lead-gen account, and worth reading before you decide which one you’re actually diagnosing.

Where to actually start
Three questions, in order:
- What’s your current monthly ad spend, or the budget you’re about to commit? That places you in a band above.
- Is anyone checking the account daily, or does it get looked at once a month? Daily coverage catches a fatiguing creative or a broken Pixel inside a day, not inside a billing cycle. A monthly check-in finds the same problem three or four weeks late, after the budget’s already been spent against it. If you’re weighing up bringing someone in rather than fixing it yourself, here’s what to actually ask before you hire a Facebook ads agency.
- Do you know what your competitors are actually running right now? Most Shopify founders don’t. It’s public data, and it’s the fastest way to find out if you’re behind on creative, not spend.
I run a free teardown that answers the third one directly. I pull your named competitors’ live ads, check what your Pixel is actually firing, and name the one thing burning your budget. No call required, sent in 48 hours, yours to keep either way. Get your free teardown here.
So, how much should you spend?
If you’re not running Meta ads yet: start with at least $1,500-2,500/month, enough for the algorithm to actually learn from real data, not a token test budget. Anything below that and you’re paying for the platform’s learning phase without ever getting past it.
If you’re already spending and weighing up a management fee on top: find your band above, then do the arithmetic yourself before anyone pitches you a tier. And if the leads are already coming and sales aren’t, don’t reach for the budget slider first. Reach for the funnel behind the click instead. That’s the whole method. No rule of thumb required.
