Every ROI calculator needs four core metrics: time saved, revenue gained, cost reduced, and payback period. Time saved is the easiest to quantify because most teams can estimate hours spent on manual processes. Revenue gained covers upsell, conversion rate improvements, and faster deal cycles. Cost reduced includes tool consolidation, headcount optimization, and error reduction.
Payback period answers the question every CFO asks: how long until this pays for itself? Calculate it by dividing the total annual cost by the monthly value delivered. A payback period under 6 months makes procurement straightforward. Over 12 months, you need a stronger narrative around strategic value.
Industry-specific benchmarks add credibility. Compare the prospect's current performance to industry averages, then show where your product moves them. This frames your product as a competitive advantage, not just a cost center.
