How this calculator works

Enter the acquisition-related sales and marketing spend for a period and the number of new customers gained in the same period.

Formula CAC = Sales and marketing acquisition spend ÷ New customers acquired

When to use it

Track CAC alongside gross margin, LTV and payback period rather than looking at acquisition cost alone.
