Why does buying a bond cost more than its quoted price?

A bond purchase can cost more than its quoted price because accrued interest and brokerage charges may be added at settlement. First establish what the displayed price already includes. Then reconcile the exact bond, face amount, price convention, accrued interest and charges to the total cash required. Do not add an item twice merely because it appears on another screen.

The important number for funding a purchase is the actual settlement amount. A quote of 99.2 is not necessarily $99.20, and a next coupon payment is not necessarily all interest earned during your ownership.

Identify what the quote measures

Confirm the exact security, currency, face amount and proposed trade. Check whether a displayed figure is an available offer, a previous trade, an indication or an executed transaction. A historical trade does not establish the price at which someone will sell to you now.

FINRA's bond guide explains that bond prices are commonly quoted in points representing a percentage of face value. It also describes compensating the seller for interest accrued between coupon payments and distinguishes brokerage markups or markdowns from an agent's commission.

Ask what is included in the quoted figure. Does it exclude accrued interest? Does it already incorporate brokerage compensation? Are there separate charges? Obtain the actual proposed calculation instead of assuming that every platform uses the same display.

In this guide, clean price means the price excluding accrued interest. The bond amount including that interest is a separate figure. The final cash amount may also contain an explicitly separate commission. Keep the definitions visible rather than treating any label reading total as self-explanatory.

Interest can accrue before it is paid

The SEC's Investor.gov definition describes accrued interest as interest earned but not yet paid. A bond's scheduled coupon can span time before and after a purchase.

For a purchase between coupon dates, the settlement record can include compensation to the seller for the relevant earlier portion. That payment is not automatically another brokerage fee, and it does not increase the bond's face amount.

Check the actual coupon dates, settlement date, day-count convention and entitlement to the next payment. Ask the broker to show the calculation. Counting elapsed calendar days by eye can differ from the convention the actual security uses.

Also verify whether the displayed amount already includes the accrued interest. A correct calculation added to an already complete amount produces an incorrect total.

One original between-coupon purchase

Consider a wholly fictional fixed-rate bond with $1,000 face value and a 4.8 percent annual coupon. Its supplied schedule pays two equal coupons of $24 each year. The bond is not callable, its maturity is after the next coupon, and the example does not assess an actual issuer.

For this teaching case, the current coupon period has 180 days under the supplied counting convention. Seventy-five of those days have elapsed at settlement. There are 105 days left until the next coupon, and the buyer is entitled to that entire next $24 payment.

The quoted clean price is 99.2 points, meaning 99.2 percent of $1,000: $992. It contains no accrued interest or brokerage compensation. The broker acts as agent and charges a separate, complete $8 purchase commission.

There are no other purchase fees, custody charges, borrowing, taxes or distributions in the finite pretax cash illustration. All specified payments arrive in full and on time. These are invented terms and prices, not current market offers, typical commissions or a recommendation to buy.

Bridge the quote to the cash required

The seller's accrued-interest amount is the $24 period coupon multiplied by 75 divided by 180: $10. Adding it to the $992 clean price gives a $1,002 bond amount before the separate commission.

Adding the $8 commission makes the complete settlement cash $1,010. The difference from the clean quote is $18: $10 accrued interest and $8 brokerage cost.

The buyer's face amount is still $1,000. The $10 does not buy another $10 of principal, and the $8 commission does not change the coupon promise. They belong in the purchase cash record, with their separate explanations.

The buyer has $1,100 specifically available after protecting all other obligations. Funding the actual $1,010 leaves $90. Planning from the $992 quote alone would wrongly suggest $108 left, overstating available money by $18.

The next coupon arrives later. It cannot fund settlement retroactively. Nor is an expected sale of another investment available cash until the actual funding arrangement and dates support it.

Check a display that already includes interest

Suppose a different screen describes this same transaction's $1,002 bond amount as its price, explicitly including the $10 accrual but excluding the $8 commission. Starting from that field, add only $8 to reach the same $1,010 settlement cash.

Adding the $10 again would produce $1,020, an overstatement of $10. The arithmetic is easy; the difficult part is identifying the starting field correctly.

Likewise, if a confirmation already gives the complete $1,010 net amount including the commission, adding another $8 would produce a different error. Ask which fields are components and which are totals.

A separately identified charge is also different from a markup already incorporated in a price. Do not manufacture a second charge from your understanding that the brokerage must be paid. Reconcile the actual disclosed arrangement.

The next coupon is not all new interest

Under the supplied counting convention, the buyer holds the bond for the remaining 105 days of this period and then receives $24. Of that coupon, $10 corresponds to the pre-purchase accrual already paid to the seller.

The portion associated with the buyer's remaining period is $14: $24 multiplied by 105 divided by 180. The same result comes from $24 received less the $10 accrued-interest payment at purchase.

That $14 is before brokerage costs, any price change and taxes. It is not a complete investment return. It also does not establish a legal tax-reporting treatment for a particular account; retain the relevant purchase and income records for the actual tax review.

Paying accrued interest did not mean the buyer lost $10 for nothing. It compensated the seller for the earlier part of the coupon that the buyer will receive under this specific payment arrangement.

The coupon-and-return guide addresses a separate question about the denominator behind a bond percentage. Here, the transaction record prevents a whole coupon from being mistaken for entirely new interest earned since purchase.

A short holding result with every cash flow

Now extend the original fictional purchase into one supplied sale scenario. Immediately after the buyer receives the $24 coupon, the bond is sold at a clean price of 98.1 points, or $981. At this explicitly post-coupon settlement point, no accrued interest is payable on the sale.

A complete separate sale commission of $6 leaves $975 of sale proceeds. The buyer also received the $24 coupon, so total ending receipts are $999.

Against the original $1,010 paid, the finite pretax cash loss is $11. Dividing negative $11 by $1,010 gives about negative 1.09 percent over the supplied holding period. It is not an annual yield or a prediction of the bond's price.

Reconstruct the same result another way. The clean price fell by $11, from $992 to $981. The buyer's portion of the coupon was positive $14. Purchase and sale commissions together were $14. Negative $11 plus $14 less $14 again leaves negative $11.

Do not subtract the $10 accrued interest a second time from that reconstructed result. It has already been removed when the whole $24 coupon was reduced to the buyer's $14 portion.

The scenario assumes a willing buyer and the stated price. A plan to sell at the next coupon date needs an executable transaction, not just a convenient date in an illustration.

Keep the other bond risks in their own review

A correct settlement total does not establish that the bond suits your purpose or that the issuer can make its payments. Read the actual issuer documents, contractual terms and relevant credit information before relying on promised money.

Call features would change the possible payment schedule; the callable-bond guide handles that separate issue. This example deliberately supplies no call so the settlement and coupon allocation remain visible.

Likewise, an apparent discount to face value is not a guaranteed profit. Face value is a contractual amount, while an early sale depends on the actual transaction. The worked sale above ends in a loss despite receiving the full coupon assumed.

Compare alternative offers using matched securities, face amounts, settlement dates and complete charges. Different dates can produce different accrual amounts. A lower cash total is not automatically a cheaper quote if it buys a different amount or carries different rights.

What to keep after the trade

Retain the security identifier, face amount, actual confirmation, price definition, settlement date, accrued-interest calculation, disclosed compensation and net cash amount. Compare the account's actual debit with that confirmed total. If a debit combines several purchases, reconcile each security and quantity before comparing their total with the account movement.

If something differs, ask the broker to explain the specific field or amount through a verified contact route. Preserve the original record and the response. Do not correct an account's history by adding an imagined fee to make your own spreadsheet balance.

When a coupon or sale arrives, connect it to the same transaction record. That gives you a way to distinguish received cash, previously paid accrual, commissions and price changes without counting any of them twice.
