Triple Whale Stats

Net Profit =
Sales - Returns - Expenses (COGS, Shipping, Handling, Payment Gateways, Taxes, Custom Spends) - Blended Ad Spend.
Blended ROAS (Return on Ad Spend) =
Sales / Blended Ads.
MER (Marketing Efficiency Ratio) =
Percentage of Sales spent on Ads.
The marketing efficiency ratio (MER) is another way to calculate the overall value of ad spend relative to overall revenue.
Your MER is a more holistic way of viewing paid advertising’s impact on revenue rather than channel-by-channel profitability. This allows for a more high-level analysis of ad spend as a larger part of the marketing puzzle rather than narrowly focusing on the ROAS of individual ads.
Net Margin =
Net Profit / Sales x 100. In other words: Percentage of Sales that is Net Profit. Answers the question: “What percentage of my [Sales] is my [Net Profit]?”
By tracking increases and decreases in its net margin, a company can assess whether current practices are working and forecast profits based on revenues. Because companies express net profit margin as a percentage rather than a dollar amount, it is possible to compare the profitability of two or more businesses regardless of size.
RPS (Revenue Per Session) =
Sales / Web Sessions.
RPS (or RPV, Revenue per Visitor) is a measurement of the amount of money generated each time a customer visits your website. It is calculated by dividing the total revenue by the total number of visitors to your site and is a method of estimating the value of each additional visitor.
Like other online business metrics, RPS helps you see what is working and not working in your company’s overall sales efforts. The revenue per visitor metric helps you evaluate new visitor acquisition efforts to see which strategies are working. RPS can also be used to determine how much you can afford to spend on paid user acquisition.
Returns % =
Refunds / Sales. The percentage of your returns relative to your sales.
Blended Ad Spend =
Total Ad Spend. This includes the reported ad spend of each marketing channel connected to Triple Whale, plus any Custom Spends marked as Ad Spend.
NCPA (New Customer Cost Per Acquisition) =
New Customers / Blended Ad Spend.
Cash Turnover =
Sales - Shipping - Taxes - Blended Ad Spend - Returns.
New Customer ROAS (Return on Ad Spend) =
Sales from New Customers / Blended Ad Spend.
BA ROAS (Blended-Attributed ROAS) =
Total Blended Conversion Value (reported by each marketing channel) / Blended Ad Spend
