Lead Cost Calculator

Receipts

If ROAS is below 3 and gross margin under 50%, every new dollar of ad spend digs the hole deeper.

How this is calculated

• cost_per_lead = ad_spend / leads
• customers = leads × close_rate_pct/100
• cac = ad_spend / customers
• revenue = customers × avg_job_value
• gross_profit = revenue × gross_margin_pct/100
• roas = revenue / ad_spend
• profit_per_lead = (gross_profit − ad_spend) / leads
