FV is a common abbreviation in the financial industry that refers to a Future Value. However, there are several other synonyms that can be used interchangeably. These include the Present Value (PV), Compound Interest, Annuity, Accumulated Value, and Deferred Annuity. All these synonyms are used to calculate the financial value of an investment over time. The Future Value (FV) is calculated by taking the Present Value (PV) and adding the interest earned over the investment period.
