The formula to calculate proportion in Excel is:
Proportion = Numerator / Denominator
Our calculator uses this formula to perform the calculation. When you select ‘Part’, it calculates the part of the whole that the numerator represents. When you select ‘Whole’, it calculates the whole that the denominator represents.
