The '''complex multiplier''' is the multiplier principle in [[Keynesian economics]] (formulated by [[John Maynard Keynes]]). The multiplier is a rather simplistic version of this.
It applies to any change in [[autonomous expenditure]], in other words, a change in [[Consumption (economics)|consumption]], investment, government expenditure or [[net exports]]. Each of these operates to increase or reduce the [[Static equilibrium (economics)|equilibrium]] level of income in the economy.

* any '''increase''' to an injection will be multiplied to result in a higher level of [[aggregate expenditure]].
* Any '''decrease''' in an injection will be multiplied to result in a lower lvl of aggregate expenditure.
* Any '''increase''' in a withdrawal will be multiplied to result in a lower lvl of Aggregate expenditure.
and...
*Any '''decrease''' in a withdrawal will be multiplied to result in a higher lvl of aggregate expenditure.

The size of the multiplier should take account of all sectors. The complex multiplier can be measured by the following formula:

: <math>k = 1 / [MPS+MRT+MPM] = 1 / MPW\,\!</math>

where MPS= Marginal propensity to save,
MRT= Marginal rate of taxation,
MPM= marginal propensity to import.
MPW = Marginal propensity to withdraw
