Does this calculator use any industry-average benchmarks?

No. Every result is computed only from the numbers you enter; the only external figures on this page are clearly labelled reference notes, never part of the calculation itself.

What counts as a 'good' CAC payback period?

There is no universal answer — it depends on your margins, funding position and how long you can wait for cash back. Published venture-context research puts healthy ranges roughly between 6 and 24 months depending on customer segment, but a small business without external funding may need a much shorter payback than a venture-backed one.

Why does cohort retention use a compounding formula for monthly churn instead of just dividing?

Because churn compounds: losing 5% a month is not the same as losing 60% over twelve months — it is roughly 46%, since each month's churn applies to a smaller remaining base. The calculator solves for the monthly rate that compounds to your observed retention over the period you entered.

What if my cash conversion cycle is negative?

That is a genuinely strong position — it means you collect from customers before you have to pay suppliers, so growth funds itself rather than consuming working capital. Many subscription and prepaid-retail businesses run negative cash conversion cycles by design.

Is this financial or investment advice?

No. It is general strategic arithmetic. Actual accounting, GST/tax treatment and working-capital financing decisions should go through a chartered accountant or the lender directly.

Revenue Mix Calculator

Revenue tells you which line is loudest. Contribution tells you which line is paying for everything else, and they are frequently not the same line.

Revenue against contribution

Price times volume is revenue. Margin applied to revenue is contribution - what the line leaves behind once its own costs are met. Ranking lines by each usually produces two different orders.

The blended figure

Total contribution over total revenue is the blended margin, and it is what has to cover everything the lines do not: the overhead, the unbilled time, and the lines that have not worked yet.

What a mix cannot show

It says nothing about how much attention each line costs to run. A small-contribution line that consumes half your week is a different problem from one that runs itself, and no arithmetic here can see the difference.

Real questions, short answers.

What margin should I enter?

The one this line actually achieves after its direct costs, not the one on the price list. If you do not know it, that is the finding.

Why only four lines?

Four is usually enough to see the shape. If you have many more than four, the prior question is whether they are really separate lines.

Should I include a line with no volume yet?

Leave it at zero. A projected line mixed with realised ones produces a blended figure that describes neither.
