Multiplier Effect

Definition§

The Multiplier Effect is defined as the proportional change in final income that results from an injection or withdrawal of capital into the economy. It’s like the top-selling hit at an economic concert—one special change brings the whole audience to life (or to tears)—resulting in an amplified impact on overall economic output. 💸

Key Formula§

The most basic formula to calculate the multiplier effect is: $$\text{Multiplier} = \frac{\text{Change in Income}}{\text{Change in Spending}}$$
