TikTok Ads ROAS & CPA Formula

Calculates return on ad spend and cost per acquisition using impression-based funnel modeling with format-specific conversion multipliers.

Clicks = Impressions × CTR
Conversions = Clicks × Conversion Rate × Format Multiplier
ROAS = Total Revenue ÷ Ad Spend
CPA = Ad Spend ÷ Conversions
Profit Margin = (Revenue − Ad Spend) ÷ Revenue × 100

Spark Ads receive a 1.25x conversion multiplier reflecting their 2.6x higher CVR vs. standard in-feed ads based on 2026 benchmarks.
