You use the multipliers.
Suppose you have an A% increase followed by a B% increase, then the value V is increased to
V*(1+A/100)*(1+B/100).
Therefore, the multiplier is (1+A/100)*(1+B/100) = 1+A/100+B/100+AB/10000
So the compound percentage increase is A + B + A*B/100.
Note that for compounding a C% decrease, the multiplier is 1-C/100.
