How to calculate Inflation Rate

 Inflation Rate Definition: 

According to Prof. Rowan, inflation is the process of increasing prices continuously.

Rowan formula for calculating percentage rate of  inflation= P(t)= {∆pP(t)/P(t-1)}×100

Where, ∆P(t)=P(t)-p(t-1)

P= Price Level

(t), (t-1)= Time periods

 WPI( Holesale price Index).   

Aplication of the formula: Ex:-

Year.                    WPI.                                               {∆pP(t)/P(t-1)}×100           Inflation Rate

2002-03.             174.                                                               -----                                 ------

2003-04.             181.                                                  {(181-174)/174}×100                 4.02

2004-05.             188.                                                  {(188-181)/181}×100.                3.87
