Financial Discounting
Financial discounting is a process used by banks, businesses, and other entities to quickly assign a present value to future payments. The present value is used as a measure of value in terms of today’s money.
Discounting takes into account the time value of money. Essentially, this means that waiting for a future payment to come due leads to a decrease in value; the dollar you receive tomorrow is worth less than the dollar you get today due to inflation, the opportunity cost of having access to those funds, and other factors.
Financial discounting is the process of using a discount rate—or a rate of return that compensates for the time value of money—to calculate the present value of a future payment. The discount rate is a compounded annual rate and it’s meant to reflect the average expected rate of return across an entire market.
The calculation for a single payment can be expressed as: PV = FV / (1 + r)n, where PV is the present value, FV is the future value of the payment, r is the discount rate, and n is the number of periods over which the payment is due.
For example, if you are expecting to receive $1,000 two years from now and the discount rate is 10%, the present value of that future payment is $826.23. That’s because 826.23 multiplied by (1 + 0.10)2 (a.k.a. 1.21) equals 1000.
In terms of what discounting is used for, there are a number of applications. The most common applications include discounted cash flow (DCF) analysis, which is used to value a business or stock, and the net present value (NPV) method of project evaluation, which is used to determine whether or not to invest in a certain project.
Discounting is also used by businesses when selling accounts receivable. A business can sell its future payments (e.g., invoices due in two months) at a discount in exchange for immediate payment. The discount is necessary to compensate the buyer for the risk of nonpayment.
Financial discounting is a powerful tool that can be used to value future payments, evaluate business investments, and buy accounts receivable. It’s an important concept to understand as it is used in many aspects of finance.
