Cost Per Inquiry Calculator

The #1 KPI to Drive Marketing Efficiency

Unleash the power of precision in your digital advertising strategy with Search Influence’s Cost Per Inquiry (CPI) Calculator. Created for results-driven marketers like you, this intuitive calculator crunches the numbers associated with the #1 KPI for paid ads — CPI.

At its core, CPI calculates the cost incurred for each inquiry or lead generated from a specific marketing campaign or channel. It’s most frequently tracked as a KPI for individual digital marketing channels (i.e., paid /organic search) and/or spend across all platforms.

By tracking CPI as your top marketing KPI, you will:

• Allocate With Confidence: By understanding efficiency of each campaign, you can allocate marketing resources where they matter most.
• Streamline Your Budget: Once you know your CPI(s), you can identify areas of improvement in your strategy and ensure your dollars are put to best use.
• Drive Customer Growth: Armed with granular data to make strategic decisions, you can better attract prospective customers and boost conversion rates.

Whether you’re tracking this KPI for a current Google paid search campaign or to total your media spend across all platforms, it pays to know what you’re paying. CPI is the most important metric for marketing campaign efficiency — once you know your CPI, you can begin to optimize your efficiency.
