How the cost per acquisition calculator works
Cost per acquisition = total campaign spend ÷ attributed acquisitions.
Check your measurements and assumptions
Use acquisitions measured over the same campaign period and attribution method as spend. This simple average excludes lifetime value, organic conversions and other costs.
Review the estimate before you act
Compare this result with an independent measurement, supplier quote or institution guidance when the decision matters. Confirm that the units and assumptions match the labels above, and update the inputs when the conditions change. Keep a note of the values used so you can reproduce the estimate later. This calculator is a planning aid and does not replace professional, product-specific or local guidance.
