Calculating Mins, Mids, and Maxes

Calculation of Minimums, Midpoints, and Maximums

Given either a minimum, midpoint or maximum, and a range spread (RS), the two remaining figures may be calculated by producing a factor from the formulas in the following table and multiplying by the known quantity.

<table cellpadding=0 cellspacing=“5px” cellpadding=“5px” border=0 align=middle width="550">

To find: Minimum Midpoint Maximum

If known figure is:

Minimum   ((2+RS)/2) (1+RS) Midpoint (2/(2+RS))   ((2+(2*RS))/(2+RS)) Maximum (1/(1+RS)) ((2+RS)/((2+(2*RS))))  

For example: If a given maximum salary is $1,500 and the desired range spread is 40%, then the midpoint salary may be found by selecting the appropriate factor formula from the table, then inserting the range spread (RS) of 40%, and multiplying by the salary of $1,500:

((2+.40)/((2+(2×.40))))x$1,500, or

(2.4/2.8)x$1,500 = $1,286
