# Question: What Is The Conceptual Difference Between APC And MPC?

APC and MPC are closely related to each other.

ADVERTISEMENTS: (1) APC refers to the ratio of absolute consumption absolute income at a particular point of time.

On the other hand MP represents the ratio of change in consumption to change in income; MPC is the rate of change in APC.

## How is APC and MPC calculated?

The average propensity to consume (APC) is the ratio of consumption expenditures (C) to disposable income (DI), or APC = C / DI. The average propensity to save (APS) is the ratio of savings (S) to disposable income, or APS = S / DI. 1.

## What is APC in macroeconomics?

In economics, the average propensity to consume (APC) is the fraction of income spent. It is computed by dividing consumption by income, or . Sometimes, disposable income is used as the denominator instead, so , where C is the amount spent, Y is pre-tax income, and T is taxes.

## Why must the sum of MPC and MPS always equal 1?

Why must the sum of the MPC and the MPS equal 1? MPC is the fraction of the change in income spent; therefore, the fraction not spent must be saved and this is the MPS. The change in the dollars spent or saved will appear in the numerator and together they must add to the total change in income.
