A good shortcut I use is for calculating cumulative interest / growth.
x% growth followed by y% growth is equal to a growth of (x+y).xy % overall. Eg. 6% followed by 8% growth is 14.48% overall growth.
You can easily extend this to account for negative growth rates, more decimal places and so on. Very useful in tracking business metrics, portfolio valuation and so on.
