Computes CAC, ARPA of new customers, gross margin, CAC payback in months on gross-margin-adjusted new MRR, and burn multiple over a trailing window from the reconciled bank categories, the owner's payroll split and the MRR waterfall, citing the bank rows behind every input, and refuses (BLOCKED, naming what is needed) when an input such as the payroll allocation is missing instead of estimating it. Use when someone asks "what's our CAC payback", "calculate our burn multiple", "what's our gross margin really", "are our unit economics investable", "how much does a customer cost us to acquire", or after mrr-movements. Do NOT use for benchmarking against other companies or choosing target ratios (use wshobson-startup-metrics-framework), for pricing strategy (use saas-pricing), or with numbers typed in by hand rather than reconciled by the earlier gates.This is the skill's description: the text your AI reads to decide when the skill applies.
