show % difference from one week to the next

[#1]

Hi below  i have a very simple flat table in qlik sense when i select weeks 42 and 43 i would like to see the % difference either as a figure in the bottom

could this be done from a KPI  chart ?

Week	Cost 1
42	125
44	14

Week	Trips	Rev/Trip
Week 42	1068	£ 497.02
Week 44	949	£ 401.25
Diff	119	£ 95.77
%	113%	124%

any help is most appreciated

thanks
