... relation to its initial value in t. For example, if income rises from 200 to 208 during the course of 12 months the (annual) growth rate is (208-200)/200 = .04 or 4%. Calculations of this kind are very easily done in spreadsheets, but care is needed with the time units being used. With quarterly dat ...
