| ---------- | -------- | ----- |
| Meta Ads   | \$12,400 | 50%   |
| Google Ads | \$8,600  | 35%   |
| TikTok Ads | \$3,750  | 15%   |

## How It Works

Blended Spend aggregates advertising costs from all connected ad platforms into a single metric. Data syncs daily from each platform's reporting API. Currency conversions use the exchange rate at time of spend.
