Understanding Business Ratios
A quick primer on what each ratio actually measures and why it matters for growth, profitability, and strategy.
Conversion Rate
Conversion rate ties visitors or leads to completed actions, whether that’s a purchase, signup, or form fill. It’s the clearest signal of how well a funnel is actually working.
Cost to Benefit Ratio
Comparing total benefits against total costs turns a subjective “is this worth it” question into a defensible number, useful for prioritizing competing projects.
Customer Acquisition Cost
CAC reveals what it truly costs to win a customer. Paired with lifetime value, it tells you whether your growth engine is sustainable or quietly burning cash.
Employee Efficiency Ratio
This ratio ties output, revenue, or units produced to headcount or hours, helping identify where a team is stretched thin or where capacity is underused.
Margin Ratio
Margin expresses profit as a percentage of revenue, not cost — the distinction from markup trips up more pricing decisions than any other business ratio.
Market Share
Market share puts your revenue in context against the whole industry, turning an abstract sense of “doing well” into a measurable competitive position.
