Percent change represents a change as a portion or a multiplier of the base number. So if you start with n=10 and end up with m=15, your percent change is the difference (5) divided by the base (10), which is 0.5, or 50%.
When your base gets really, really small (close to zero), your percent change gets really, really large (in mathematical terms, it approaches infinity). When your base is actually zero, the percent change has no meaning, since there is no such thing as a portion (or a multiplier) of nothing.
120 million percent.
You cannot since in such a case a percentage increase cannot be defined.

Percent change is the percent amount some value has changed. It has phenomenal usage in every day math and in fields such as business. It's often used to calculate the percent difference in sales between years for business.

A stock broker uses percent of change. Almost any buisness might use it to calculate the money gained over a certain period of time.
Zero point zero four percent.
To calculate the percent change from 144 to 204, first find the difference: 204 - 144 = 60. Then, divide the difference by the original value: 60 / 144 = 0.4167. Finally, multiply by 100 to get the percent change: 0.4167 × 100 = 41.67%. Therefore, the percent change from 144 to 204 is approximately 41.67%.
As written '05 percent' , you would say 'zero five percent'. However the 'zero' to the left is trivial in whole numbers, so you would just say ' five percent'. However, I think you mean ' 0.5 percent'. Note the position of the decimal point, In which case the 'zero' is NOT trivial, and you would say ' zero point five percent'. Or possibly '0.05 percent' in which case it is 'zero point zero five percent '. Clarity of your meaning and question would be appreciated.
.0 × 0 = 0 Therefore, it is neither, simply nothing.
(Final-Initial)/(Initial) is the formula for percent change (multiply by 100 to make it a percentage) I think this is what you are looking for.
