Budget Scaling Rules

Scaling ads too fast kills profitability. Scaling too slow misses opportunity. These rules ensure you scale budget only when data supports it — never scale a losing campaign.

Situation	Action	Reason
ROAS > 1.5× break-even for 3 days	Scale Up 20%	Proven winner — profitable enough to scale

Scaling Up vs Scaling Down

When to Scale Up

ROAS consistently above 1.5× your break-even ROAS for 3+ days (for 40% CM, break-even ≈2.5x, so scale above ~3.75x)

Cost per purchase is below target CAC

CTR is above 2% and stable

Frequency is below 3 per user per week

Ad set has completed learning phase

You have cash flow to support 2-week payout delay

Action: Increase budget by 20% every 3 days, maximum 60% per week

When to Scale Down

ROAS below break-even for 3 consecutive days

Cost per purchase exceeds target CAC by 50%+

CTR has dropped 30%+ from peak

Frequency is above 5 per user per week

Creative has been running for 14+ days without refresh

Audience is exhausted (reach >80% of estimated)

Action: Cut budget by 30%, or pause entirely if ROAS <1x

Never Scale Unprofitable Ads: Increasing budget on a campaign that's losing money doesn't fix it — it just loses money faster. If ROAS is below your break-even ROAS after 7 days with proper creative and audience, kill the campaign and start fresh. For a typical 40% CM product, break-even ROAS is 2.5x — anything below that is losing money. Sunk cost bias will destroy your marketing budget.

Budget Scaling Checklist

Only scale campaigns with 3+ days of ROAS above 1.5× break-even

For 40% CM product, break-even ≈2.5x — so scale above ~3.75x

Increase budget by max 20% per scaling step

Bigger jumps reset the learning phase

Wait 3 full days between each budget increase

Let the algorithm re-stabilize after each change

Keep a testing budget (20-30%) running at all times

Never put 100% budget into scaling — always be testing

Refresh creatives every 10-14 days to prevent fatigue

Creative fatigue is the #1 reason scaling stops working

Track blended ROAS (total revenue ÷ total ad spend) weekly

Individual campaign ROAS can be misleading — look at the whole picture
