What is CPA (Cost per Acquisition)?

By Nikhil Sharma · Updated 1 November 2026 · Marketing Glossary
Definition

Cost per Acquisition (CPA) is the amount you pay for one conversion — a sale, sign-up or defined action — from a specific campaign.

How to calculate CPA

CPA = Total campaign spend ÷ Number of acquisitions (conversions)

Spend ₹50,000 and get 25 conversions and your CPA is ₹2,000. The ‘acquisition’ is whatever you define as the conversion — a purchase, a demo, a signup.

CPA vs CAC vs CPL

CPA is per campaign conversion; CAC is the all-in cost to win a paying customer across everything; CPL is the cost of a lead. CPA sits between — a defined action that may or may not be a full customer. Ad platforms optimise toward a target CPA.

How to improve CPA

  • Raise conversion rate with better landing pages.
  • Tighten targeting to higher-intent audiences.
  • Improve ad relevance to lower CPC.
  • Cut spend on actions that don't become revenue.

Questions, answered

CPA is the cost per defined conversion in a campaign (a sale, signup or action); CAC is the total, all-in cost of acquiring a paying customer across all sales and marketing. CAC is broader and usually higher.

It depends on the value of the conversion and your margins. A good CPA is comfortably below what that acquisition is worth to you. Judge it against revenue and lifetime value, not as a standalone number.

Improve landing-page conversion rates, tighten targeting to higher-intent audiences, raise ad relevance to lower click costs, and stop spending on actions that do not turn into revenue.
