Got this from an old Northfield post, wondering if it still applies:

2 clients per month, assuming a 40% close ratio =
5 new prospect meetings per month. Assuming 20% of cold called prospects agree to a meeting, then
25 new prospects in the pipeline every month. Assuming 10% of folks you have a phone conversation with qualify themselves and agree to receive some info then you need to have
250 new phone conversations with prospects every month. And assuming you are able to have an intelligible conversation on 10% of your dials then you need to  dial
2500 times per month or
125 per day.
 
Of course, if your average client is $100k, this only yields you $2.4 million per year, so if you wanted $5 mill per year you would need to double this math.
 
This math has remained one of the few constants in our ever-changing business. Try it, you'll see what I mean
