CFt

CFt is an abbreviation that can refer to multiple concepts in different fields, and there is no single universally accepted meaning. Its interpretation depends on the context and notation. The most common usage is in finance, where CF_t (often written with a subscript t) denotes the cash flow occurring at time t.

In financial modeling, CF_t appears in calculations of net present value, internal rate of return, and discounted cash flow analyses. Example: NPV = sum_t CF_t / (1 + i)^t, where i is the discount rate. In this setting, CF_t represents the amount of cash inflow or outflow in period t and is combined with a discount factor to determine present value.

Other uses occur in technical or algorithmic contexts: CFt may simply be a variable name representing a function value over time, or may denote domain-specific terms in research, software, or documentation. Because CFt is not standardized, readers should rely on surrounding definitions to determine its precise meaning in a given document.

In summary, CFt is a time-indexed term whose exact meaning is situation-dependent. The most widely recognized interpretation is cash flow at time t in financial calculations, but the abbreviation can appear in various disciplines as a generic time-indexed variable or as part of specialized terminology. When encountering CFt, it is advisable to check how the author defines it within that specific text.
