Calctric
Electrician Calculator & Tools
$4.99 · Designed for iPad. Not verified for macOS.
Built for electricians: calculate tape fractions, check CEC and NEC voltage drop, and plan conduit bends in clear 2D and 3D layouts.
CalcTric is a practical calculation tool built for electricians, apprentices, and tradespeople.
It combines an imperial measurement calculator, electrical voltage-drop tools, and a comprehensive conduit bending studio in one clean, field-friendly app.
IMPERIAL CALCULATOR
Calculate directly with inches and fractions without constantly converting measurements to decimals.
• Add, subtract, multiply, and divide measurements
• Enter common fractions quickly
• Refine measurements to the nearest 1/16"
• View fractional and decimal results together
• Copy results for use elsewhere
Designed around the measurements you actually see on a tape measure.
VOLTAGE DROP
Calculate voltage drop and explore different circuit variables using tools designed for Canadian and U.S. electrical work.
Calculate:
• Conductor size
• Voltage drop
• Maximum circuit length
• Maximum current
• Maximum K value
• Voltage-drop percentage
Configure circuit type, voltage, current, distance, conductor material, power factor, wiring method, operating temperature, and other calculation inputs.
CalcTric supports Canadian CEC-based and U.S. NEC-based voltage-drop calculation settings.
BEND STUDIO
Plan conduit bends and see the layout before making your marks.
Supported layouts include:
• Offset
• Rolling offset
• 3-point saddle
• 4-point saddle
• 90° saddle
• 90° stub
• Kicked 90°
• Back-to-back 90°
• Custom bend sequences
Bend Studio calculates measurements, spacing, shrink, and mark positions and provides interactive 2D and 3D visualizations to help you understand the finished layout.
Configure conduit and bender information so calculations can account for the equipment you're using.
BUILT FOR THE FIELD
CalcTric brings frequently used trade calculations together in a fast, straightforward interface with no account required.
Whether you're laying out conduit, checking voltage drop, or working through measurements, CalcTric is designed to reduce repetitive math and keep the information you need close at hand.
IMPORTANT
CalcTric is a calculation and reference tool. Results should be independently verified before use. Electrical installations must comply with applicable codes, regulations, manufacturer instructions, and requirements of the authority having jurisdiction. CalcTric does not replace professional judgment, required inspections, or applicable electrical codes.
IMPERIAL CALCULATOR
Work naturally with feet, inches, and fractions without converting everything to decimals first. CalcTric makes it easy to add, subtract, multiply, and divide measurements commonly used on the job.
VOLTAGE DROP
Quickly estimate voltage drop using conductor and circuit information. The calculator is designed with Canadian electrical work in mind and provides a convenient way to evaluate voltage drop while planning an installation.
CONDUIT BENDING
Access practical conduit-bending calculations for common bends and layouts. Enter your measurements and let CalcTric handle the math so you can focus on the installation.
BUILT FOR THE FIELD
• Clean, straightforward interface
• Fast calculations with minimal input
• Imperial measurements designed around real tape-measure fractions
• Light and dark appearance support
• Useful for electricians, apprentices, tradespeople, and DIY calculations
• No account required
