Common questions
Helpful answers
How is the customer price calculated?
The app adds labor cost and material cost to find total job cost, then divides that cost by one minus your target margin percentage.
Where is my information stored?
Calculator entries and settings stay locally on your device. GPM Calculator does not create an account or transmit your job information to B33ZU Labs.
How do I reset the calculator?
Tap Clear above the input fields to reset the current mode, or use Reset Defaults in Settings to restore the original company defaults.
