Simple Interest and Compound Interest Formulas

Before solving SBI PO questions, it's important to know the basic formulas. Many questions can be solved quickly by applying the correct formula.

Simple Interest (SI)

Formula: SI = (P × R × T) ÷ 100 

Where:

• P = Principal

• R = Rate of Interest (% per annum)

• T = Time (in years)

Compound Interest (CI)

Formula: CI = P(1 + r/n)^(nt) - P

Where:

• FV = Future Value (Amount)

• PV = Principal

• r = Interest rate per period

• n = Number of compounding periods

Knowing these formulas will help you solve SI and CI questions accurately and efficiently in the SBI PO exam.
