What is a good CPA for Facebook ads in 2026?

CPA benchmarks vary enormously by industry. E-commerce: $15–$45. Lead generation (B2C): $20–$60. SaaS B2B: $100–$400. Healthcare: $80–$200. The right CPA is whatever's below your customer lifetime value while leaving healthy margin. If a customer is worth $300, a $60 CPA yields 5x payback.

How do I calculate target CPA for Facebook ads?

Target CPA = Customer Lifetime Value × maximum allowable marketing cost percentage. If your product sells for $99 (one-time) with 60% gross margin, your maximum CPA for profitability is $59.40 (99 × 0.6). If you want a 3x return on ad spend, target CPA = $33 (99 ÷ 3). Work backwards from your unit economics, not from industry averages.

What is the average CPM on Meta/Facebook ads?

Average Meta CPM ranges from $8–$20 depending on targeting, placement, and vertical. Q4 (Oct–Dec) CPMs spike 40–70% due to e-commerce competition. Broad audiences cost less per impression but convert worse. Retargeting audiences have higher CPMs but far better conversion rates. Feed placements cost more than Reels or Stories.

What conversion rate should I expect on my landing page?

Average landing page conversion rates: e-commerce product pages 1–3%, lead gen opt-in pages 5–15%, webinar registrations 20–40%, free tool sign-ups 10–25%. The conversion rate is the biggest lever in your CPA equation — doubling your CR from 1% to 2% halves your CPA without changing your ad spend.
