How the math works

Most margin calculators only subtract COGS. That gives you gross margin — a number that flatters DTC brands because it ignores the costs that actually break them.

  1. 01

    Subtract product costs

    Start with revenue, deduct COGS. That's gross profit — the upper bound on what's possible before the rest of the business gets its cut.

  2. 02

    Subtract delivery + fees

    Shipping and payment processor fees (typically 2.9–3.5%) come straight off the top. Not optional. Rarely free. Always larger than you remember.

  3. 03

    Subtract ad spend + returns

    Every dollar paid to Meta, Google, TikTok, Klaviyo, and every refund issued. What's left is net profit — the only number that pays salaries.
