How This Calculator Works

This market sizing calculator models a typical B2B sales funnel with six stages:

  1. Top of Funnel: Total outreach volume across all channels (emails, calls, LinkedIn, ads, website, referrals)
  2. Responses: Contacts who engage with your outreach (based on channel-specific response rates)
  3. Qualified Leads: Responses that have budget, authority, need, and timeline (BANT)
  4. Meetings Held: Qualified leads who book AND attend a discovery call
  5. Proposals Sent: Meetings that warrant a formal proposal
  6. Deals Closed: Proposals that convert to signed contracts

The default values represent industry benchmarks, but you should adjust them based on your actual data. Track your metrics over 3-6 months to get accurate conversion rates for your specific market and offer.

Pro Tip: A healthy LTV:CAC ratio is 3:1 or higher. If yours is below 3:1, focus on improving conversion rates or increasing average deal size rather than just increasing outreach volume.
