How the calculator works
Outreach is a funnel: a share of your messages get replies, a share of replies turn into trials or calls, and a share of trials become paying customers. Multiply those three rates and you get the share of messages that end in a sale. Divide your target by that share and you get the number of messages to send.
Worked example
With the placeholder numbers above (5% reply rate, 20% of replies become trials, 25% of trials pay), about 0.25% of messages become customers. To land 10 customers you would need to send roughly 4,000 messages. Those numbers are illustrative only. Use your own.
Where to get your own rates
If you have not sent any outreach yet, you do not have real rates. Send a small batch first (for example 50 to 100 personal messages), record what happens, then plug in what you measured. Treat the result as a planning estimate, not a promise.
Limits of this calculator
It assumes your rates stay constant as you send more messages, which is rarely true. It does not model deliverability, list quality, or follow-ups. It is a tool for deciding whether a plan is realistic, not for forecasting revenue.
FAQ
Is a 5% reply rate normal? It is only an example. Reply rates depend on who you contact, what you offer, and how good your message is. Measure your own.
Does this work for channels other than email? Yes. The math is the same for direct messages or any outreach where you can count messages, replies, trials, and sales.
