  • Accrued Interest: A Young Professional’s Guide
Author: Joseph Reinke, CFA

Navigating your personal finances is like reading a language you were never taught. Irrespective of the complexity, there is one term that has the power to either befuddle or bolster your financial literacy – ‘accrued interest’. For young professionals just starting on your financial journey, accrued interest is often synonymous with jargon. Yet, understanding accrued interest is a pivotal step toward financial empowerment.

In this guide, we’ll go over the mystery of accrued interest. From its fundamental definition to practical applications in loans, investments, and ethical considerations, this guide will give you the know-how to turn this ‘financial benchmark’ in your favor.

Understanding Accrued Interest: The Basics

Before we plunge into a myriad of scenarios accrued interest touches, it’s critical to grasp its foundational nature.

What is Accrued Interest?

Accrued interest essentially refers to the interest that has been incurred on a loan or other outstanding financial products but has not yet been paid. It builds up over time, typically on a daily basis. For lenders, this interest represents earnings that have not been received yet. For borrowers, it’s added to your loan and paid when you make your monthly payment.

The accrual of interest typically occurs everyday. I.e. Every day you are charged interest on your loan and it accrues as an amount owed.

Dual Role in Finance

Accrued interest’s prominence in finance is twofold. First, it outlines the cost an individual or business pays for the use of someone else’s money. Second, it signals the forthcoming inflow of cash that a lender or investor expects to receive from their capital deployments.

The Calculation of Accrued Interest

The tussle with accrued interest often boils down to its calculation, which varies depending on the type of loan or investment involved.

For Loans:

The formula for calculating accrued interest on loans is relatively straightforward:

Accrued Interest = Principal x Interest Rate x Time

Where ‘Time’ is proportionate to the interest period, typically in days. Here’s how it works in practice:

Example Calculation for a $10,000 Loan at 6% Annual Rate for 15 Days:

Accrued Interest = $10,000 x 0.06 x (15/365)

Accrued Interest = $24.66

For Investments, Specifically Bonds:

The world of bond investing is where accrued interest can get rather nuanced. Day-count conventions in the bond market dictate various methods, such as 30/365 and actual/actual, for different bond types.

Actual/Actual Example:

If a bond pays semi-annually and the last payment was 168 days ago in a year with 365 days, the accrued interest will be for a period of 168/365 of a year, applied to the next 6-month interest payment.

Accrued Interest in Different Financial Products

The influence of accrued interest extends across a spectrum of financial products, each painting a unique portrait of its utility.

Credit Cards:

Accrued interest on credit cards can be a trap for the uninformed, given the often-hefty rates and compounding frequency. Knowing how this interest accrues can mean the difference between a healthy credit score and a mountain of debt.

Mortgages and Student Loans:

Here, accrued interest plays a significant role in the overall cost of the loan and can introduce complexities such as deferment and forbearance into the equation.  To make things more complicated, if you are on an income driven student loan repayment plan, you may have your accrued interest forgiven each month!

Savings Accounts:

Savings accounts aren’t immune to the allure of accrued interest; your account balance quietly accrues interest daily, adding to your financial fidelity without any extra effort on your part.


Navigating bond accruals requires an understanding of the bond’s coupon, payment frequency, and the day the bond was bought or sold — factors that culminate in the accrued interest you’ll receive or pay.

Managing Accrued Interest Effectively

For young professionals, managing accrued interest is a harbinger of financial prudence.

    The Power of Tools:

    Leverage the plethora of financial calculators and tools available online to demystify and predict the trajectory of accrued interest in your financial ventures.

    Legal and Ethical Considerations

    Intertwined with the financial finesse accrued interest requires is a tapestry of legal and ethical considerations.

    Transparency in Lending:

    Lenders are obliged to disclose the terms under which interest accrues, allowing borrowers to make informed decisions and avoid falling into debt spirals.

    Fair Lending Practices:

    Scrutiny over lending practices often circles back to how accrued interest is managed and communicated. Bridging this gap with fairness ensures that accrued interest doesn’t become a tool for predatory lending.

    Ethical Investing:

    For investors, the ethical application of accrued interest means understanding the businesses or entities your investments support and whether they align with your principles.
