Rate definitions

Keep every denominator consistent.

Contact rate is a percentage of total leads.
Quote rate is a percentage of contacted buyers.
Close rate is a percentage of quoted buyers.
Cost per acquired sale uses estimated completed sales.

ROI and break-even method

Use gross profit, not revenue.

Lead-spend ROI is contribution after lead cost divided by total lead cost. The break-even close rate divides total lead cost by estimated quotes multiplied by gross profit per sale. If break-even exceeds 100%, those assumptions cannot break even.
