ARR growth rate and CAGR calculator API

Compute period-over-period ARR growth = (endARR - startARR) / startARR and optional CAGR = (endARR/startARR)^(1/periods) - 1 with absolute growth and breakdown. Compounded-growth math LLMs misstate. Answers 'what is my ARR growth rate','what is my ARR CAGR','how fast did my ARR grow'.
