• Reverse-calculation electric-field modeling can estimate individualized tDCS doses.

• Individualized tDCS doses widely vary (range: 3.75 to 9.74mA to produce 1V/m).

• •DCS applied at a uniform 1-2mA dose may underdose some individuals.

• Transcranial electrical stimulation (TES) motor thresholds (MTs) correlate with reverse-calculation tDCS doses (R2 = 0.45, p < 0.001).

• TES MT or reverse-calculation modeling could become methods to individually dose tDCS and warrant further investigation.
