What is referred to as the amount of money coming in and out in a given interval?

The term that describes the amount of money coming in and out in a given interval is cash flow. Cash flow specifically tracks the inflows and outflows of cash within a business or individual’s finances over a specified period. It is essential for assessing the financial health of an entity, as it indicates whether there is enough liquidity to cover expenses, invest in opportunities, and manage debts.

The other terms, while related to financial concepts, do not directly capture the idea of cash movement over a specific time frame. For instance, profit margin refers to the difference between revenue and the costs associated with generating that revenue, reflecting profitability but not the movement of cash. Revenue stream pertains to the sources from which income is generated but does not account for outflows. Investment return refers to the gains or losses made on an investment relative to the amount invested, which is a more specific measure of financial performance rather than cash flow tracking.
