TikTok CPA calculator

Your cost per conversion and the most you can pay.

Quick answer

CPA = ad spend ÷ conversions. Max CPA = order value × gross margin, so a Rp800.000 order at 40% margin can afford up to Rp320.000 per sale.

Start from an example:

Campaign results

Ad spend

Conversions (purchases)

Your economics

Average order value

Gross margin before ads

After product, shipping and platform fees.

Conversions depend on the attribution window you use. The 30% buffer is a rule of thumb, not a TikTok number.

How do I lower my CPA?

Test new hooks, send traffic to a fast product page, raise order value with bundles and give campaigns time to exit learning.

Should I use cost cap bidding?

A cost cap near your target CPA can protect margin, but too low a cap can stop delivery.
