Cost Per Lead Calculator

Marketing platforms report cost per lead. That number is misleading on its own because only a fraction of leads become customers. A $50 cost per lead looks great until you find out your close rate is 15 percent, which means your real customer acquisition cost is $333.

Two numbers matter: cost per lead (marketing spend divided by leads received) and cost per acquired customer (marketing spend divided by customers closed from those leads). Track both, but base decisions on the second one.

The break-even cost per lead is the maximum you can spend per lead and still profit on the customers you close. Formula: (average job gross profit) x (close rate). If your average job produces $1,500 gross profit and you close 25 percent of leads, break-even CPL is $375. Anything under that produces net profit; anything over loses money at the marketing line.

For most residential trades: HVAC replacement leads break even around $200 to $500. Roofing replacement leads $300 to $600. General remodel leads $200 to $800 depending on average project size. Handyman and service work $30 to $100.

Lead brokers sell the same lead to three to five contractors simultaneously. If you and four other contractors each pay $75 for the same lead, that homeowner is fielding calls all afternoon and taking the fastest or cheapest offer. Your effective close rate on shared leads is typically half or less of your organic close rate.

The math falls apart quickly. A $75 shared lead with an 8 percent close rate on a $500 gross profit job produces $500 x 0.08 = $40 in expected gross profit against $75 spent. You lose $35 per lead in expectation, even before overhead.

Exclusive leads from an owned local website flip the ratio. Same $75 effective cost per lead, but 25 to 35 percent close rate because the homeowner called one company, not five. Now $500 x 0.30 = $150 gross profit against $75 spent. That is a marketing channel that pays.

Raise the close rate. Answering the phone within 60 seconds instead of two hours can double the close rate on cold leads.

Raise the average job value. Bundling related work, upselling maintenance plans, and quoting the whole job instead of the immediate problem all increase revenue per customer without increasing lead cost.

Improve lead quality. Move spend away from broad channels (mass display, cheap directory listings) toward high-intent search where homeowners are actively looking for your service.

Own the marketing channel. Exclusive local sites, owned domains, and organic search rankings produce leads that cost near zero once the site is ranked, versus paid channels that reset to full cost every month.
