Discount

In finance, a discount is a reduction from a stated price, face value or future amount. The term covers a genuinely wide range of related ideas: an ordinary price discount on a retail purchase, a bond trading below its own face value, an early promotional-rate discount offered on an adjustable rate mortgage, and the considerably broader concept of discounting future cash flows to express their equivalent value in today's money.

What unites these different uses is the shared underlying idea that something is being valued, or deliberately offered, at less than its full stated or eventual amount, whether for a limited promotional period, because broader market conditions have pushed a security's price down, or simply because money received at some point in the future is inherently worth less than the same amount received right now.

A $1,000 bond that currently trades for only $950 is said to be trading at a discount — buyers are paying meaningfully less than the bond's eventual payoff value, usually because prevailing interest rates have risen since the bond was first issued, making its older fixed coupon rate relatively less attractive compared with newer bonds now available.

In lending, a discounted introductory rate offered on an ARM works in a broadly similar way: the lender temporarily reduces the stated rate below its normal index-based level for a limited promotional period, after which the rate typically rises back up to its full level once that initial period ends.

A bond trades at a discount when its current market price sits below its stated face value, typically because market interest rates have risen above the bond's own fixed coupon rate since issuance, making the bond meaningfully less attractive at its original price and pushing its market price steadily down until its effective yield roughly matches comparable newer bonds available for purchase today.

In valuation work, discounting is the process of converting a future amount of money into its equivalent value today, using a chosen discount rate that reflects both the time value of money and the perceived risk of the cash flow itself, a technique central to approaches such as discounted cash flow analysis and the dividend discount model used widely in equity valuation.

A discount point on a mortgage is a related but genuinely distinct concept, referring to an upfront fee a borrower pays specifically to reduce the ongoing interest rate for the full life of the loan, effectively trading a larger one-time payment today for a smaller monthly payment every month going forward for as long as the loan remains outstanding.

Outside investment markets entirely, businesses commonly offer trade discounts off a standard list price to particular classes of buyer, and separately offer early-payment discounts, such as "2/10 net 30," which gives a customer a small percentage reduction off the invoice if paid within ten days rather than the full standard thirty-day term, effectively rewarding faster payment with a modest built-in discount.

Some bonds, called original issue discount bonds, are deliberately sold below face value from the very start rather than paying a stated coupon rate at all, with the investor's entire return coming from the gradual difference between the discounted purchase price and the full face value eventually received at maturity, a structure that also carries specific, somewhat unusual tax treatment in many jurisdictions on the imputed interest accruing each year.

Investors holding these instruments generally need to track that imputed interest carefully each year, since tax authorities in many countries require it to be reported as income even though no actual cash interest payment is ever received until the bond finally matures.
