Awaiting Your Figures

No estimate has been calculated.

Enter the figures available to you, then select Calculate ROI. Zero or missing values remain visible as unavailable rather than being replaced with example performance.

What The Numbers Mean

ROI only matters when profit survives the margin.

Revenue can look healthy while profit disappears. The useful question is whether the commercial model appears able to pay for acquisition, convert enough leads, and leave room for further review.

Lead Efficiency

Enter at least one lead to calculate cost per lead.

Customer Cost

Enter a positive lead volume and conversion rate to calculate cost per customer.

Break-Even Control

Enter a positive customer value and gross margin to calculate break-even.
