Questions

## Calculator, _explained._

How is the wasted spend estimated?

Nothing is pulled from your account. Our floors are ours, not an industry average. They are at least five active creatives, a visit-to-lead rate around three percent, and a freshness penalty from six months through 24. Where you fall short, the model assigns a share of spend using those assumptions. That is a scenario to investigate, not a measurement of lost money. Total waste is capped at 45%. A rate under four percent still shows as a remaining gap.

Is this a guarantee?

No. It is a directional estimate to size the opportunity from the numbers you enter. Your real number depends on your account, offer, and market. Book a consult and we will check your actual data.

What if I do not know my CAC, or it is above the slider?

Use your best guess. Drag the CAC slider to roughly what a new customer costs you today, or click the number and type the exact figure, including amounts above the slider range. If you also know what a new customer is worth, add that optional field and we will show the ratio next to the waste.

What does the optional customer-value field do?

Nothing, unless you type a number. We do not invent lifetime value. When you enter 90-day or first-year revenue per new customer, we show value-to-CAC and how much customer value the wasted spend represents. We do not annualize it, and the ratio uses revenue, not gross profit.

Do I need to pay, or give an email?

Neither. Every leak and the target cost per customer show on screen. Email is only for a copy of the report.
