Compound Interest for SSC CGL, Railway NTPC & CDS | Concepts, Formulas & Easy Tricks

The chapter Compound Interest (CI) is an essential part of the Arithmetic syllabus for SSC CGL, CHSL, CPO, GD, and Railway exams. It focuses on interest calculated on both the principal and accumulated interest. Students learn formulas for annual, half-yearly, and quarterly compounding, along with effective rate, difference between CI and SI, population growth, and depreciation-based questions. CI problems often involve percentage increase patterns, making them similar to profit–loss and percentage concepts. This chapter is high-scoring because formulas are fixed and many questions follow repeated patterns in exams. Strong basics help solve CI questions quickly and accurately.
