Calculate minimum Break-Even ROAS, maximum profitable CPA, unit contribution margin, and monthly net ad profit for TikTok Ads campaigns. At the calibrated baseline of Order / Sale Price ($ — Incl.

Whether selling on Shopify, Amazon FBA, Etsy, or TikTok Shop, profitable scaling requires calculating your exact Break-Even ROAS—the minimum ad multiplier where revenue per order equals total variable costs—before increasing daily ad budgets. Specifically for TikTok Ads CPA, accounting for Platform / Payment Fee (% — Verify rate) (3) and Fulfillment & Shipping Cost ($) (4.5) yields Net Profit Margin %: 36.64% and Break-Even ROAS Threshold: 1.77x.
II. TikTok Ads CPA Formula & Mathematical Mechanics
The TikTok Ads CPA Calculator engine evaluates the closed-form equation ExVAT = Price / (1 + VAT%) | UnitNet = ExVAT - COGS - (Price×Comm%) - Shipping - (Price×Return%) - AdCPA. Pre-ad Unit Contribution Margin is defined as Order Price (AOV) minus Landed COGS (manufacturing, freight, packaging, and 3PL pick-and-pack) minus marketplace/platform referral commission. This dollar amount represents your Maximum Allowable Cost Per Acquisition (Max CPA).
On a $55.00 order (Ex-VAT: $55.00, VAT: $0.00), deducting $15.50 COGS, $1.65 (3.0%) platform commission, $4.50 shipping, and $2.20 (4.0%) return allowance yields a pre-ad contribution margin of $31.15 (Break-Even ROAS = 1.77x). Subtracting $11.00 Ad CPA leaves $20.15 net profit per order (36.64% margin; $5,037.50 across 250 orders). Verify commission & fulfillment rates on your platform's fee schedule. Break-Even ROAS is the reciprocal of your pre-ad contribution margin ratio: Break-Even ROAS = Order Price / Pre-Ad Contribution Margin. If a $69 product has $32.40 in COGS and platform commission, your pre-ad contribution is $36.60 (53.0%), making your Break-Even ROAS 69 / 36.60 = 1.89x.
