Pentane Efficiency Score (PES)

PES is a special score that ranks overall efficiency across the business.

How it's calculated

It's a combined score from variable margin (w/o ads), fixed expenses compared to revenue, ROAS, and net profit margin, normalized to compare easily (exact formula is in Pentane's system).

What it means

PES helps pick the best sales paths to grow. By focusing on high-score ones, you scale what makes money, avoiding bad ones, and boost overall eCommerce profits.

How it's calculated

Variable Margin (Without Ad Spend) = Variable Expenses Without Ad Spend / Total Revenue x 100%

What it means

This shows the amount of sales related expenses per dollar earned, without ads. High value means your products are priced low (this could be discount or sale related). Driving more profit by testing prices up and removing, or reducing, discounts is critical for both growth and survival.
