Required Residual Vote Calculator:

  • Let Bo represent the initial vote count for candidate B

  • Let To represent the initial vote count for candidate T

  • Let R represent the residual amount of votes remaining

  • Percentage required appears dynamically in the box

Algebra:

Break-even point for each candidates total votes equal: B = T

Bo + x/100*R = To + (1-x/100)*R; where x is the percentage of remaining votes won by B to even the count

Solve for x = -100*[(Bo-To) -R]/(2*R)

Sane percentages, i.e., positive values, are only provided when R > vote difference

This calculator is provided "as is".
