Questions

About this calculator

Why is 3:1 the benchmark?

It leaves enough gross profit after acquisition to cover overhead and still fund growth. Much below and you are buying revenue with cash you do not get back quickly enough.

Is a very high ratio good?

Not necessarily. A ratio of 10:1 usually means you are under-investing in marketing and leaving growth on the table.
