About 2.0 clients, ROI 3,727%
Emailing 1,000 leads at a 3.4% reply rate, 30% interested and 20% of those closing gives about 2.0 clients, worth $5,998 over 6 months, against $157 of cost: an ROI of 3,727%.
Worked example with the default inputs. Change any number and press Calculate.
- Expected revenue: $5,998 ($3,000 per client)
- Total cost: $157; cost per client: $78.38
- Clients to break even: 1
- List cost at 67Leads: 1,000 credits, the first 67 free on signup; the other 933 take 1 pack of 1,000 at $6.70, $6.70 in total.
The formula
delivered = 1,000 x (1 - 2%) = 980 replies = 980 x 3.4% = 33.3 interested = 33.3 x 30% = 10.0 clients = 10.0 x 20% = 2.00 revenue = 2.00 x $500 x 6 months = $5,998 cost = list $6.70 + other $150 = $157 ROI = ($5,998 - $157) / $157 = 3,727%
How this works
Expected values, step by step: leads that do not bounce, times the reply rate, times the share of replies that are interested, times the share of interested replies that become clients. Revenue is clients times monthly value times months retained. Cost is the list at 67Leads' public credit price plus whatever else the campaign costs you. Fractional clients are kept so small campaigns are not rounded to zero; read 0.4 clients as a 40% chance of one.
Where the defaults come from
