The math, shown

Cost per lead	marketing spend ÷ leads	CPL is what you pay for each lead. $12,000 ÷ 300 = $40.
Cost per customer	CPL ÷ close rate	Only some leads convert, so the real acquisition cost is higher: $40 ÷ 20% = $200.
Max profitable CPL	(customer value × margin) × close rate	The most you can pay per lead and still break even on margin: $144. Bid below it and volume is safe.

To lower CPL: tighten targeting and negative keywords, improve landing-page conversion, and test offers and lead magnets. To raise the ceiling: lift close rate with faster follow-up and better qualification, and grow customer value.
