Customer Acquisition Cost (CAC) is the all-in price you pay to turn a stranger into a first-time buyer. On TikTok Shop, CAC runs $12–$35 for a typical beauty/fashion seller — or free if you're leaning on affiliates. This calculator totals every acquisition channel (ads, affiliate commissions on first orders, content production) into one defensible number.

  • CAC = ad spend ÷ new customers — include only NEW (not repeat) buyers from the campaign window.
  • LTV : CAC ratio — 3:1 is healthy. Under 1:1 is bleeding money. Over 5:1 is under-investing in growth.
  • Payback period — months to recover CAC from LTV / 12. Under 12 months is strong.
