It is due to '%' sign in 12.50%

pasring is done in the same way you did it or,

float.TryParse also you can use .

It's the % which is causing a problem here. Either use DecimalFormat with a custom pattern, or strip the % before you parse.

You should also be aware of cultural context - will the input always use . as the decimal separator, or do you need to use the locale of the supplier of the value? For example, in some locales this would be represented as "12,50%".
