#64%#increase

Percentage loss, profit, increase, decrease, discount or mark-up are all calculated in exactly the same way:

#%" change" = ("change")/("original") xx 100%#

In this case the number has gone from #50 to 82#

This is obviously an increase of #32# from the original #50#

#%" change" = 32/50 xx100%#

=#64%#increase

To find the percentage change from 50 to 82, you use the formula:

Percentage change = [(New value - Old value) / Old value] * 100

= [(82 - 50) / 50] * 100

= (32 / 50) * 100

= 0.64 * 100

= 64%

The percentage change is an increase of 64%.
