How to Use the Meeting Booking Calculator: Step-by-Step Guide
The Meeting Booking Calculator projects how many meetings your cold DM campaign will generate and what each meeting costs. This guide walks you through each input and how to interpret the output for campaign planning.
Step-by-step walkthrough
Enter your send volume
Start with the total number of DMs you plan to send. This is the top of the funnel — everything downstream is a percentage of this number. Be realistic: use the volume you can sustain given your platform limits and team capacity.
Input your reply rate
What percentage of recipients reply to your DM? Use your historical average if you have one. If not, start with 5–10% for well-targeted campaigns. The calculator multiplies your send volume by this rate to project total replies.
Set your positive reply rate
Of the people who reply, what percentage express genuine interest (not just 'thanks' or a polite decline)? This rate typically ranges from 30–60% for well-targeted outreach. The calculator uses this to project qualified leads.
Enter your booking rate
What percentage of interested prospects actually book a meeting? A common range is 40–70%. If your booking process has friction (scheduling back-and-forth, qualification forms), use the lower end.
Review projected meetings and cost per meeting
The calculator shows how many meetings you'll book and what each one costs. Use this to decide whether the campaign is worth running at your current volume and cost structure.
Worked example
A B2B consultant sending 1,000 DMs to marketing directors with a $2,500 campaign budget.
| Metric | Value |
|---|---|
| DMs sent | 1,000 |
| Reply rate | 8% |
| Replies | 80 |
| Positive reply rate | 45% |
| Interested prospects | 36 |
| Booking rate | 55% |
| Meetings booked | 20 |
| Campaign cost | $2,500 |
| Cost per meeting | $125 |
At $125 per meeting, the consultant needs a close rate above 25% on a $2,000+ deal to break even on campaign cost. With a 30% close rate on $3,000 contracts, the campaign generates $18,000 in revenue from a $2,500 investment.
Key metrics to track
Reply rate
Replies ÷ DMs sent. Benchmark: 5–12% for targeted cold outreach.
Positive reply rate
Interested replies ÷ total replies. Benchmark: 30–60%.
Booking rate
Meetings booked ÷ interested prospects. Benchmark: 40–70%.
Cost per meeting
Campaign cost ÷ meetings booked. Should be below your max allowable cost per meeting.

Frequently asked questions
What's a good cost per meeting benchmark?
It depends on your deal size. For a $5,000 service, a $150 cost per meeting is excellent if your close rate is above 25%. For a $500 product, $150 per meeting is too high. Divide your average deal value by your close rate to find the maximum cost per meeting you can afford.
Should I count all replies or only positive replies?
Track both. Total reply rate tells you about message engagement. Positive reply rate tells you about pipeline potential. The calculator uses both to give you an accurate meeting projection.
How do I improve my booking rate?
Reduce friction: offer specific time slots instead of 'let me know when you're free,' use a scheduling link, and keep the qualification lightweight. A booking rate below 40% usually means your CTA is too heavy or your follow-up is too slow.
Can I use this for team campaigns?
Yes. Enter the total volume across all team members and the blended rates. If each rep has different rates, compute a weighted average reply rate and positive reply rate across the team.
