How this calculator works

True profit = Monthly revenue − every expense above (core + hidden). Most owners only track core costs (product, ads, fees) and miss the slow drip of software, packaging, and refunds.

Hidden cost % = Hidden expenses ÷ revenue. Anything above 10% means your tool stack and small recurring costs deserve a serious audit.
