The operating reality
Does the deposit cover commitments due before the next payment?
Deposit − (upfront materials + early labor + other upfront costs); coverage = deposit ÷ upfront costs.
Enter only costs due before the next customer draw. This is a timing view, not the final profitability of the job.

What the calculator does
Deposit − (upfront materials + early labor + other upfront costs); coverage = deposit ÷ upfront costs.
Read the result
Use the number as a decision baseline
Enter only costs due before the next customer draw. This is a timing view, not the final profitability of the job.
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 and negative values resolve to zero. Zero upfront costs avoids division by zero while showing the deposit as surplus.

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 and negative values resolve to zero. Zero upfront costs avoids division by zero while showing the deposit as surplus.
