Hi folks,

I hope someone might be able to help me with this one. At work, we calculate a number of measures as simple percentages, and refer to 'uplift' as an amount of effort required to increase percentage by 1%.

For example, if we achieved a target for 7500 out of 10000 items then we achieved 75%; to get to 76% we could do three things;

1) add 100 to the numerator,

2) subtract approx 132 from the denominator,

3) add approx 417 to the numerator and denominator.

The first value is straightforward, it's 1/10th of the denominator. I'd like to know how to calculate the amounts for options 2 and 3.

Any help would be greatly appreciated.

Scott
