MPW (Marginal Propensity to Withdraw) = Marginal Propensity to Save (MPS) + Marginal propensity to tax (MPT)+ Marginal Propensity to Import (MPM)
MPS (proportion of additional income that is saved)=
a change in Savings/ a change in National income
MPT (Proportion of additional income that is taxed)=
a change in Taxation/ a change in National income
MPM (the proportion of additional income that is spent on imports)=
a change in imports/ a change in National income

The marginal propensity to consume (MPC) is an economic concept to show the increase in personal consumer spending or consumption that occurs with an increase in disposable income. Here is the formula: MPC = change in consumption/change in disposable income A change in disposable income results in the new income either being spent or saved. This is the Marginal Propensity to Consume (MPC) or the Marginal Propensity to Save (MPS). MPC + MPS = 1
If the consumption function is C50 0.75y then the marginal propensity to consume is?
To calculate the spending multiplier in an economy, you can use the formula: Spending Multiplier 1 / (1 - Marginal Propensity to Consume). The Marginal Propensity to Consume is the proportion of additional income that people spend rather than save. By plugging in the value for the Marginal Propensity to Consume, you can determine the overall impact of an initial change in spending on the economy.
average propensity to consume is the fraction of the total amount of disposable income that households spend on consumption whereas marginal propensity to consume is the amount that consumption increases for every additional dollar of disposable income.

Taxation Multiplier = - (MPC) / (1 - MPS) Where, MPC = marginal propensity to consume, and MPS = marginal propensity to save.
The formula for this simple tax multiplier. (m[tax]), is: m[tax] = - MPC x 1 ---- MPS = - MPC ---- MPS Where MPC is the marginal propensity to consume and MPS is the marginal propensity to save. This formula is almost identical to that for the simple expenditures multiplier. The only difference is the inclusion of the negative marginal propensity to consume (- MPC). If, for example, the MPC is 0.75 (and the MPS is 0.25), then an autonomous $1 trillion change in taxes results in an opposite change in aggregate production of $3 trillion.
average propensity to consume is the fraction of the total amount of disposable income that households spend on consumption whereas marginal propensity to consume is the amount that consumption increases for every additional dollar of disposable income.
To determine the marginal propensity to consume, divide the change in consumption by the change in income. This ratio shows the proportion of additional income that is spent on consumption.
The average propensity to consume is the fraction of total disposable income that households spend on consumption (as opposed to saving for example) whereas marginal propensity to consume is the additional consumption that results from an additional dollar of disposable income.
we do care about the marginal propensity to consume because it shows the ratio of an increase in consumption due to increase in income it does not matter what the income of the consumer,either high or low.

In an open economy, the formula for the multiplier is expressed as ( \text{Multiplier} = \frac{1}{1 - MPC + MPM} ), where MPC is the marginal propensity to consume and MPM is the marginal propensity to import. This formula reflects how initial changes in spending lead to larger overall changes in national income, accounting for both consumption and imports. The presence of imports dampens the multiplier effect compared to a closed economy, as some of the spending leaks out of the domestic economy.
