How to calculate
Use ideal negative-feedback gain for the selected topology around the reference. Compute the unbounded output, then clamp it to user-entered voltage bounds.
Inverting G=−Rf/Rin; non-inverting G=1+Rf/Rg; output=reference+G(signal−reference)
Worked example
With reference 0 V, input 0.5 V, Rf=100 kΩ and Rin=10 kΩ, inverting gain is −10 and output is −5 V. Non-inverting gain is 11 and output is 5.5 V.
Assumptions and input details
Ideal static voltage-feedback model. In inverting mode, the non-inverting terminal is at the reference voltage; in non-inverting mode the resistor return is the reference. Bounds are explicit output assumptions, not inferred power rails. No gain-bandwidth, slew rate, common-mode range, stability, output current, offset or real-device saturation recovery model. Zero feedback resistance is allowed as an ideal limit.

Unit definitions
Unit selection is independent of language. Each selector contains only units for its physical quantity. Calculations use defined base units internally.
SI prefixes are explicit: for example, milli means one thousandth, micro one millionth and kilo one thousand. Changing a unit changes the interpretation of the entered number.
Using this calculator
Can I enter my own problem?
Yes. Replace the example values with your own inputs. The result, calculation steps, tables and applicable diagrams update from those inputs. Blank or invalid values clear the result; example values are never silently substituted for missing inputs.
Are the results exact?
Results use floating-point arithmetic and displayed rounding. Read the formula, assumptions and any stated data precision before interpreting the result.
Is my input uploaded?
The calculation runs in your browser. No account, file upload or external AI service is required. Inputs are not saved between page reloads.
Compare unloaded and resistively loaded divider voltage, branch currents and dissipation.
Convert power or root-power amplitude ratios to decibels and back. Add independent source levels that share a reference, using logarithmic power addition.
Calculate an ideal one-string resistor or current and compare entered supply, forward-drop and resistor-tolerance corners.
