Lead source ROI and cost per lead answer different questions.
CPL measures how much it costs to generate one lead. Lead source ROI measures whether the source produced enough revenue for its cost.
A low CPL is useful only if those leads become customers. A high CPL can still work if the source has better lead quality, stronger close rates, or higher customer value.
Use the Cost Per Lead Calculator at /tools/cost-per-lead-calculator to measure lead cost, then use the Lead Source ROI Calculator at /tools/lead-source-roi-calculator to understand source-level return.
