The formula to calculate the Marginal Propensity to Save (MPS) is:
\[ MPS = \frac{dS}{dI} \]
Where:
MPS, known as Marginal Propensity to Save, is a measure of how much extra money a person saves when they receive an increase in income. It is the proportion of any additional income that is saved rather than spent. The higher the MPS, the more likely a person is to save additional income rather than spend it.
Let's assume the following values:
Using the formula to calculate MPS:
\[ MPS = \frac{200}{1000} = 0.20 \]
The Marginal Propensity to Save (MPS) is 0.20.
