About this prompt
This prompt helps AEs and sales engineers build a custom ROI model for a specific deal by calculating total cost of ownership, net ROI, payback period, and a breakdown of hard and soft value. Use it at proposal stage when you need to justify price or build a customer business case. It requires real cost and benefit inputs from discovery — rough numbers produce rough models.Price objections disappear when the math is clear — this prompt builds the math. Input your solution's annual cost, implementation cost, and time to value, along with the customer's current solution cost, people involved, time spent on the problem, revenue impact, and expected improvements from your solution. The output includes a total cost of ownership calculation, net ROI percentage, payback period, and a value breakdown separating hard savings (quantifiable, defensible) from soft benefits (productivity, risk reduction). Use this at proposal stage or during business case development, not in early discovery when numbers aren't firm yet. For AEs who need a quick back-of-napkin model for a deal call, use the simplest possible inputs; for a formal business case document, get the actual numbers from your champion. The more accurate the current-state costs, the more credible the model is when it reaches the economic buyer.The prompt
