Finance metrics that matter

A metric earns its place by changing a decision. Most finance dashboards contain a dozen numbers and two decisions — here is how to fix the ratio.

Key takeaways
  • A metric that never changes a decision is decoration.
  • Definitions must be fixed and documented, or trends become meaningless.
  • Six to eight metrics cover most operating companies.
  • Trend matters more than level for almost every metric.
  • Segment before you aggregate — averages hide the interesting cases.

The test for including a metric

Ask what you would do differently if this number moved twenty per cent in either direction. If the answer is nothing, it does not belong in the pack — it belongs in an appendix, if anywhere.

This test removes about half the contents of a typical finance dashboard, and the remaining half gets read.

A defensible core set

MetricDecision it informs
Net cash movementWhether to slow hiring or discretionary spend
Runway on committed spendWhen to start raising or cut costs
Gross margin by segmentWhere to focus sales effort, and what to price differently
Contribution marginWhether growth improves or worsens the position
Days sales outstandingWhether collections need intervention
Revenue retentionWhether the product is holding its customers
Spend per employee by cost centreWhere cost growth is outpacing headcount

Definitions have to be frozen

Most metric disputes are definitional. If burn includes capital expenditure this month and excludes it next month, the trend is noise and nobody can tell.

Write the definitions down once, including exactly which accounts feed each metric, and change them only deliberately with a note in the report.

  • Document each metric's formula and source accounts.
  • Note any change of definition in the period it changes.
  • Restate prior periods when a definition changes, or the trend is meaningless.
  • Keep the same definitions across internal and investor reporting.

Numbers that rarely change anything

These are not wrong, but they seldom drive a decision on their own, and they crowd out the ones that do.

  • Total registered users, without an activity qualifier.
  • Cumulative revenue since inception.
  • Headcount as a standalone metric rather than against output or cost.
  • Any average that spans genuinely different segments.

Frequently asked questions

Usually six to eight, with segmentation available underneath. More than that and the pack becomes a document people skim rather than read.

The definitions should not. The selection can differ, but reporting a metric one way internally and another way externally erodes trust the moment someone notices.
