Build an ROI Model from Prospect-Provided Assumptions

Create an ROI model with formulas, variable ranges, and sensitivity notes based only on prospect-provided assumptions.

About this prompt

This prompt builds a simple ROI model for a specific offer using only the assumptions the prospect has provided — no invented numbers. It outputs formulas, variable definitions, assumption ranges, and sensitivity notes showing where the ROI is most and least defensible. Use it in late-stage deals when you need to justify the commercial investment with a model a CFO can stress-test.ROI models fail credibility when they invent favorable assumptions — this prompt is built around the constraint of using only what the prospect has told you. Provide your [offer], [pricing], and [the prospect's specific numbers — headcount, process costs, current tool costs, revenue targets] to get a model with clearly labeled input variables, formulas that show the math, scenario ranges (conservative, base, optimistic), and explicit flags for assumptions that need further validation. Use this over a generic ROI calculator when you're building a model a financially literate buyer will scrutinize. Tip: the sensitivity analysis output is the most valuable section for executive conversations — showing which input variable drives the most variance in ROI outcome gives you a roadmap for where to gather more data before the final commercial review.
