CPA Calculator computes Cost Per Acquisition by dividing total advertising spend by the number of conversions, with support for tracking across multiple campaigns and time periods. It handles attribution windows, distinguishes between marketing-qualified and sales-qualified acquisitions, and compares CPA against customer lifetime value (CLV) to determine campaign profitability. The tool also calculates blended CPA across channels and marginal CPA to identify the point of diminishing returns.
Performance marketers optimizing ad spend, growth teams setting acquisition budgets, and CFOs evaluating marketing ROI across business units. The tool runs entirely in your browser — your data never leaves your device.
