Cost Per Lead Calculator

Divide campaign spend by leads generated to get CPL, the first hard number in demand generation.

About Cost Per Lead Calculator

Dividing spend by the number of leads gives the unit economics of the channel. The reciprocal — leads delivered per unit of currency — is shown alongside, because that is the figure to maximise when a budget is fixed. Unit cost is the only number that lets you compare channels with wildly different budgets, and it is the input every bid and budget decision ultimately rests on.

Formula

Cost Per Lead

Cost Per Lead = Campaign spend ÷ Leads generated

Campaign spend: Total amount spent in the period
Leads generated: Countable outcomes delivered for that spend

Assumptions and limits

The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
This is an estimate for general information and not professional financial, tax or legal advice. See the full disclaimer for the limits that apply to this kind of calculator.
