<h3>What is discount rate?</h3>
The bank rate, sometimes known as the discount rate in American English, is the interest rate charged by a central bank on its loans and advances to commercial banks.
In a discounted cash flow (DCF) analysis, the discount rate is the interest rate used to calculate the present value of future cash flows. This helps establish whether the future cash flows from a project or investment will be worth more than the initial capital outlay required to support the project or investment.
The discount rate is an essential measure of an economy's credit situation.
