What Is a Rebate?

A rebate, broadly, refers to a sum of money that is credited or returned to a customer in the context of a transaction. A rebate may offer cashback on the purchase of a consumer good or service, either as a flat-rate rebate, which is automatically subtracted from the purchase price, or conditional rebates, which are only valid under certain conditions, such as "buy one, get one free." Some conditional rebates require the purchaser to submit a form along with proof of payment to the company offering the cashback.

In securities trading, a rebate often refers to the portion of interest or dividends paid by a short seller to the owner of the shares being sold short. Short selling requires a margin account

Key Takeaways

  • A rebate involves compensating a purchaser or owner with cashback or other forms of remuneration.
  • Rebates are also the portion of interest and dividends that the borrower of stock in a short sale pays to the investor who loaned the stock.
  • Rebates on securities require margin accounts, whose balance is calculated on a daily basis based on the stock's price movements.

Understanding Rebates

Businesses offer rebates for many reasons, mainly because they can be a potent marketing tool, drawing customers who are attracted to the prospect of receiving discounts on expensive items. While companies sometimes take a loss on a rebated product, they often find a way to squeeze out a profit on them. And even when they do take a loss, customers who purchase items with rebates attached may buy other items in the store, giving the business a net profit.

Additionally, some companies "price protect" certain products by offering rebates on others, hoping that sales of products with rebates will allow them to keep other products at the desired price point.


Mail-in rebates are one of the most familiar types of rebates. Since they require a certain amount of effort, some consumers fail to take advantage of them. Many businesses take this into account when deciding to offer a mail-in rebate. Knowing in advance that only a certain proportion of customers will take the cashback, companies can estimate an average price reduction less than the rebate amount.

Vehicle Rebates

Rebates are commonly offered on new vehicles. Typically, the vehicle manufacturer pays for the rebate rather than the dealer, and then the manufacturer gives money to the dealer, who then transfers it to the consumer. By law, dealers must pass on the full amount of the rebate to the customer, provided the customer qualifies for it. Rebates sometimes harm the resale value of vehicles since they effectively lower their sticker price.

Rebates vs. Discounts and Reduced Interest Rates

Rebates are collected after payment, while discounts are taken before purchase. Discounts are more likely to be offered by retailers, while rebates are more likely to be offered by manufacturers, such as automakers.

Reduced interest rates, meanwhile, affect monthly payments on large purchases such as vehicles. For example, car shoppers are sometimes presented with a rebate and a reduced interest rate when purchasing a car. The rebate option will give the buyer more immediate cash in hand, but reduced interest rates can provide more significant discounts in the long run.

Rebates in Securities Trading

Rebate is a term used in short selling, which is selling securities that a trader does not own. In order to sell a stock that isn't owned, the trader must borrow the stock so that it can be delivered to the buyer.

When an investor places a short sale trade, that individual must deliver the stock to the buyer on the trade settlement date. The goal of selling short is to profit from a price decline by buying the stock at a lower price after the sale. Selling short exposes the seller to unlimited risk since the price of the shares that must be purchased can increase by an unlimited amount. That said, a trader can exit a short sale at any time to cap the risk.

If dividends are paid during the period that the stock is borrowed, the borrower must pay the dividends to the lender. Likewise, if bonds are sold short, any interest paid on the borrowed bond must be forwarded to the lender. Shorting a stock involves paying interest or a fee and, in some cases, the broker may forward some of that fee to the stock lender.

It is difficult for individual traders or retail investors to qualify for a rebate as it requires the holding of substantial sums in their trading accounts. Generally, large institutions, market makers, and traders with broker/dealer status are beneficiaries of rebates.

Short Sale Rebate Fee

When a short seller borrows shares to make delivery to the buyer, the seller must pay a rebate fee. This fee depends on the dollar amount of the sale and the availability of the shares in the marketplace.

If the shares are difficult or expensive to borrow, the rebate fee will be higher. In some instances, the brokerage firm will force the short seller to buy the securities in the market before the settlement date, which is referred to as a forced buy-in. A brokerage firm may require a forced buy-in if it believes that the shares will not be available on the settlement date.

Before going short, a trader should check with their broker what the short sale rebate fee is for that stock. If the fee is too high, it may not be worth shorting the stock.

How Margin Accounts Are Used in Short Stock Rebates

The Federal Reserve Board’s Regulation T requires that all short sale trades must be placed in a margin account. A margin account requires the investor to deposit 150% of the value of the short sale trade. So, for example, if an investor’s short sale totals $10,000, the required deposit is $15,000.

Since short sellers are exposed to unlimited losses, a substantial deposit is required to protect the brokerage firm from potential losses in a customer’s account. If the price of the security increases, the short seller will be asked to deposit additional dollars to protect against larger losses. If the price continues to rise on a position, causing a larger loss, and the borrower is unable to deposit more capital, the short position will be liquidated. The borrower is liable for all losses, even if those losses are greater than the capital in the account. 

For example, assume a trader shorts 100 shares at $50. They are short $5,000 worth of stock and are therefore required to maintain a balance of 50% more than that, or $7,500. If the stock drops, there is no problem since the short seller is making money. But if the stock rises rapidly, the trader could face significant losses and may be required to put more money in the account.

If the stock gaps up overnight to $80 per share, and the trader is unable to get out before that, it will cost them $8,000 to get out of that position. They will need to increase their account capital to $12,000 to keep the trade open, or they can exit the trade and realize the loss. If they take the loss, it is -$30 per share, multiplied by 100 shares, which is -$3,000. This will be deducted from the $7,500 balance, leaving them with only $4,500, less fees.

Example of a Rebate

Suppose a trader borrows $10,000 worth of stock ABC with the intention of shorting it. The trader has agreed to a 5% simple interest rate on the trade settlement date. This means that the trader's account balance should be $10,500 by the time the trade is settled.

The trader is responsible for transferring $500 to the investor, or the person they borrowed the shares from to make the trade, on the trade settlement date.
