I want to continue my words. So this things are hard to calculate by yourself and I think the fastest way is to use a percentage increase calculator that can help to calculate the percentage using a minimum number of percent that you would like to put. Since I prefer to do the work quickly (I am a financial manager) I am using it most of the times but since my math is not soo good I have used a tip about "
how to work out percentage increase" that helped me out to save my personal time for the rest.
