What Is a Basis Point? An In-Depth Look Into This Commonly Missed Financial Term

A basis point is a common financial term, but one that is often overlooked. It’s a unit of measurement used in finance that is equal to one one-hundredth of a percent (or 0.01%). While this amount may seem tiny, it is a key term when discussing interest rates or bond yields, as it allows us to express fractions of a percent in a way that is easier to understand.

Let’s start by looking at an example. Say you are comparing two investments, one with a 5% interest rate and the other with a 5.25% rate, the difference between those two rates is 25 basis points. That small quarter of a percent may not seem to make much difference on the surface, but it can add up when considering cumulative interest rate changes over an extended period of time.

Basis points are also used to measure changes in bond yields. Bond yields are used to calculate prices of bonds when they are traded, and a basis point can make a large difference depending on the difference of the yields. A change of 100 basis points for a bond with a yield of 5% would mean an entire 1% move in the price.

Basis points are also used to convey fees and commissions associated with financial transactions. Trading 1,000 shares of a stock might have a commission fee of 25 basis points. This means that the commission for the trade would be calculated as 25/100 of 1% of the total trading value of the stock.

Basis points are easy to calculate, as it is a straightforward calculation of the inverse of one-hundredth. For example, a 1% interest rate is equal to 100 basis points, and a 0.01% rate is equal to 1 basis point. Understanding basis points is essential when dealing with any type of financial security or transaction, as it allows investors to accurately assess and compare investments.

Related Legal Concepts

Understanding basis points in financial contexts often connects to broader legal concepts involving valuation and measurement. Tax attorneys frequently work with related concepts like tax basis, cost basis, and stepped-up basis when calculating gains, losses, and inheritance values for clients. These foundational measurement principles, much like basis points in finance, provide standardized methods for determining precise values in legal transactions and tax calculations.

The Bottom Line

Basis points serve as a precise measurement tool that eliminates confusion when dealing with small percentage changes in financial and legal contexts. Whether you’re reviewing loan documents, investment agreements, or fee structures, understanding that each basis point equals 0.01% helps you accurately interpret contract terms and financial obligations.
