New Operational Amplifier Gain Calculator

02/13/2026

Easy-to-use operational amplifier gain calculator is an online engineering tool for engineers, students, and technicians that helps to determine the voltage gain of an operational amplifier.

This calculator supports both inverting and non-inverting operational amplifier circuits. Just enter values for any two of the three parameters to calculate the remaining one: enter known values for R1 and Rf to calculate the voltage gain or you can enter gain and one of the resistors values (R1 or Rf) to calculate the other one.

Watch the video “How to Use Operational Amplifier Gain Calculator” and use it online.
