Introduction

Financial institutions such as banks, insurance companies, investment firms, and micro‑finance organizations depend heavily on data to make smart decisions. Even with the rise of advanced tools like Power BI, SQL, and Python, Microsoft Excel remains the most widely used tool in the financial industry, with studies showing that over 80 % of financial professionals use Excel daily for key tasks. This article explores how Excel impacts decision‑making in financial institutions, why it is still relevant today, and what its limitations are.

Why Excel Is Still the Backbone of Finance

Even in 2025, Excel remains dominant because it is easy to use, flexible, inexpensive, and familiar to almost every financial professional. Surveys show that over 70 % of banks still rely on Excel for budgeting, forecasting, and weekly performance reports, making it a core tool for both analysts and top‑level managers. Its accessibility across devices and integration with financial systems keeps it relevant in modern finance workflows.
