To find the percentage:-

First, you should find the difference between the negative and the positive numbers. Lets take your example. The difference between 2 quarters is

1,000-(-4,000) = 1,000+4,000 = 5,000

Second, neglect the negative (-) sign of a negative number and apply the percentage formula.

Now

Difference = 5,000

Starting Value = 4,000

Percentage = (Difference/Starting value)x100%

= (5,000/4,000)x100%

= 1.25x100%

= 125%

The increase in the second quarter from the first quarter is 125%
