FAQ

What is break-even ROAS?

It is the revenue-to-ad-spend ratio where profit is zero: price divided by profit before ads. Below it, ads lose money.

Should fees include payment processing?

Yes. Add platform commission and payment processing together for a realistic margin.

How do I handle currency conversion?
