The 4 scenarios every Meta advertiser hits with Cost Caps

We've got something you need to see today.

An email from one of our exclusive partners, Marin from Inspire.

His agency, Inspire, has generated over $300 million+ in revenue in the last 12 months with Meta Ads.

He's worked with some of the biggest names in the space, including The Oodie and Vessi.

And while most ecommerce brands are struggling with Meta's push toward automation, Marin's team has cracked the code on when to let the algorithm work, and when to take back control.

Today, he's sharing the exact Cost Cap playbook his team uses to scale proven campaigns past $100K/month without letting Meta's AI burn the budget on people who were already going to buy.

Let's dive in.

Hey,

If you're scaling Facebook Ads past $50K/month, you've probably asked yourself: should I use Cost Caps?

Here's the truth: Cost Caps aren't a magic bullet. But when you're already hitting your target CPA and want to scale during high-performing periods (weekends, BFCM), they're the best lever you have.

How Cost Caps actually work

Cost Caps average out over your attribution window, usually 7 days.

So if you set a $50 Cost Cap, one day might be $52 CPA, the next $47, then $42, then $57. At the end of the week? Should average to $50.

Key point: If your account is currently at $70 CPA and you set a $50 Cost Cap, Facebook won't magically fix it. You'll just see very little spend. Cost Caps are for scaling what's already working, not testing.

Where to start your bid

Start at your account average CPA, or slightly below.

Better to start conservative and increase the bid than overspend from day one.

Example: If your AOV is $100, ROAS target is 2.0x, and your account is currently averaging $45 CPA, start your Cost Cap at $45.

The 4 scenarios you'll face

Once your Cost Cap campaign is running, you'll land in one of these four combinations of spend and performance:

1) Not spending full budget + good results

You're only spending $200 of your $1,000 daily budget, but the CPA is at or below target.

→ Gradually increase your bid by $1 until you hit full spend while maintaining good results.

2) Not spending much + bad results

Low spend AND the CPA is above target when it does spend.

→ Import new winning ads if you have them. If you don't, stop using Cost Caps, they're only for scaling proven creative.

3) Full spend + poor results

Budget is fully spent every day, but CPA is above target even after 7 days.

→ Decrease your bid AND decrease your budget (don't wait hoping it averages out, you'll lose money). Refresh with new ads.

4) Full spend + good results

Budget fully spent, CPA at or below target.

→ You're scaling. Increase budget to give Facebook more room, or you started with an inflated budget and don't need to touch anything.

When to use Cost Caps

Cost Caps work best during high-performing periods when conversion rates spike:

• Weekends (more people on their phones)

• BFCM and seasonal peaks

Instead of manually guessing how much to scale, Cost Caps let Facebook scale itself while protecting your target CPA.

Bottom line: Master the spend + performance combination, and you'll know exactly what to do next.
