The benchmarks that matter
Three rough rules carry most of the signal. LTV to CAC above 3 means each customer earns back more than three times what they cost to win. CAC payback under twelve months means you are not financing growth for too long. And the Rule of 40, growth rate plus profit margin clearing 40, is the shorthand investors use to say a SaaS business is healthy. Miss all three and the engine leaks faster than it fills.
