Example

| Metric | Value | Calculation |
|---|
| Meta Spend | $2,400 | Total spent on Meta |
| Add Payment Info | 120 | Payment submissions attributed to Meta |
| Cost per Add Payment Info | $20.00 | $2,400 ÷ 120 |
How It Works
Cost per Add Payment Info divides your total Meta ad spend by the number of add-payment-info events tracked via the Meta Pixel or Conversions API. An add-payment-info event fires when someone enters payment details during checkout after engaging with your ad. Lower cost indicates more efficient acquisition of high-intent users close to completing a purchase.
