Now let’s look at where the leak may be happening: —

You already paid Google. You already paid Facebook. You built the website. You earned the reviews. The homeowner finally raised their hand.
- Demand was created
- The prospect chose to contact you
- The opportunity reached your business
The loss can happen after all that acquisition work—when the response is missed or delayed.

FREQUENTLY ASKED QUESTIONS
Is this real revenue I’m guaranteed to recover?
No. It is a modeled estimate based entirely on the inputs you provide. Its purpose is to identify where revenue opportunities may be leaking—not to promise a specific recovery result.
Why include close rate?
Not every lead becomes a completed job. Applying your close rate produces a more useful estimate than multiplying every missed opportunity by full job value.
Why estimate after-hours opportunities?
The model intentionally applies a conservative adjustment rather than assuming every after-hours opportunity would become a job.
Why does response time matter?
The calculator models a larger portion of web-lead opportunity as being at risk as response time increases. It is an estimate, not a promise of a specific conversion outcome.
Can I change the numbers?
Yes. Recalculate using conservative, aggressive or historical assumptions to see how the model changes.
