Running it, start to finish
- Gather every acquisition cost including salaries, and every serving cost including support.
- State your real retention period rather than extrapolating.
- Work on the single lever from section 7.
What you get back
The output this produces, every time.
- Includes the costs routinely omitted — salaries in acquisition, support in cost to serve.
- Reports payback period alongside the ratio, since that is the number cash actually constrains.
- Gives a range rather than a figure when retention data is too thin to support one.
Getting better results
Where this usually goes wrong, and how to avoid it.
- Include people costs. An acquisition cost built from ad spend alone is usually less than half the real number, and it is the version that makes a business look fine.
- Measure support time honestly. Section 2 is where a healthy gross margin most often turns out not to be one.
- Watch the payback period. A strong ratio with an eighteen-month payback still runs you out of cash. The ratio is the long game; the payback is this year.
