Ad Testing Engine
How much to spend per ad, per concept, and where to allocate your budget.
Built on the DTC growth framework: every dollar either scales a proven winner or tests for
the next one. This tool tells you the exact split based on your current account performance.
1. Your Account Right Now
INPUTS
Total spend/day across all campaigns
Your breakeven or target cost per acquisition
Minimum acceptable return on ad spend
Current average cost per 1,000 impressions
How many ads are currently running, and where do they stand?
Winners — these are making money
Less than 2x CPA spend, needs more data
Losers — spending above your target
Where to Find These
Numbers in Meta Ads Manager
Daily Budget: Ads Manager > All Campaigns > look at “Amount
Spent” for today or your daily budget caps across all active campaigns.
Target CPA: Your breakeven calculation: (Product Price – COGS – Shipping – Fees) = max you can pay per customer. If you don’t know this, stop and calculate it first.
Average CPM: Ads Manager > Columns dropdown > “Performance and Clicks” > find the “CPM (Cost per 1,000 Impressions)” column. Use the account-level average, not a single campaign.
Ad Counts: Ads Manager > go to the Ad level (not Campaign, not Ad Set — the Ad level). Set the date range to last 7 days. Add the “Cost per Result” column if it’s not showing. Then:

Winners = Ads where “Cost per Result” is at or below
your Target CPA AND has at least 3+ conversions
Still Testing = Ads that have been running less than 3 days OR have spent less than 1x your Target CPA
Losers = Ads where “Cost per Result” is above your Target CPA AND has spent more than 1.5x your Target CPA
Still Testing = Ads that have been running less than 3 days OR have spent less than 1x your Target CPA
Losers = Ads where “Cost per Result” is above your Target CPA AND has spent more than 1.5x your Target CPA
Tip: In Ads Manager, click “Filters” > “By Metric” > “Cost per result is greater than [your
target CPA]” to quickly see all underperformers. Sort by “Amount Spent” descending to find
your biggest money pits first.
