# MidPoint Arc Elasticity Calculator

When two variables are considered as x and y, then the elasticity of x variable with y variable is called as the arc elasticity which is calculated based on the percentage change in both x and y. Here A and B are the variables for which the midpoint arc elasticity is calculated.

#### Formula:

M = ((B2-B1) / ((B2+B1)/2)) / ((A2-A1) / ((A2+A1)/2))
**Where,**
M = Midpoint Arc Elasticity
B2 = Change in B1 Value
B1 = Initial Value
A2 = Change in A1 Value
A1 = Initial Value
((B2-B1) / ((B2+B1)/2)) = Percentage change of B Variable
((A2-A1) / ((A2+A1)/2)) = Percentage change of A Variable
