In the first case, let's suppose that you have a change in value from 60 to 72, and you want to know the percent change.. Firstly, you need to input 60 as the original value and 72 as the new value into the formula.. Secondly, you have to subtract 60 from …

Formula of calculating the percentage increase/decrease. Percentage Increase/decrease = (V new – V old) / V old x 100%, which means that the percentage increase or decrease from the old to the new value is calculated by; the difference between the old and new values which is then divided by the old figure. The result is multiplied by 100%.The principal amount included in each payment stays the same but the interest amount decreases over each payment period.
