The operating reality
What does one new paying customer actually cost?
(Ad spend + management fees + other acquisition costs) ÷ new paying customers.
Use one consistent period and count customers who actually paid. Include every selected acquisition cost; do not mix booked leads with paid customers.
Formula
What the calculator does
(Ad spend + management fees + other acquisition costs) ÷ new paying customers.
Read the result
Use the number as a decision baseline
Use one consistent period and count customers who actually paid. Include every selected acquisition cost; do not mix booked leads with paid customers.
Change one input at a time to understand the lever. The calculator is educational and does not promise financial performance.
Input safety
Blank, zero, negative, and divide-by-zero handling
Blank inputs are treated as zero. Zero closes returns ‘Not calculable’ because cost cannot be divided by zero. Negative entries are clamped to zero.

Simple dollar example
Make the economics visible.
An operator already spending $3,600 on ads, $1,500 on fees, and $900 elsewhere is spending $6,000. With 12 paying customers, the hidden baseline is $500 per close—the problem CloseDay makes visible so the operator can lower it.

Use your numbers
What do you think it costs you to acquire one customer right now?
Use one consistent period. Results use only your entries and are educational, not financial advice.
What changes
One clear rule. One accountable next action.
Keep the workflow accountable

Frequently asked questions
Practical buying questions
Is this result a benchmark or forecast?
No. It uses only the values entered and provides an educational baseline. It is not financial advice or a guarantee.
Which period should I use?
Use one consistent period across every input. A monthly spend cannot be compared with annual closes without converting one of them.
What happens with missing or invalid inputs?
Blank inputs are treated as zero. Zero closes returns ‘Not calculable’ because cost cannot be divided by zero. Negative entries are clamped to zero.
