What Is a Simple Interest Calculator?

A Simple Interest Calculator is a handy online tool that helps you compute the interest on a loan or investment without any complex formulas. Whether you’re a student, investor, or borrower, this calculator saves time and ensures accuracy in financial planning.

🔢 Formula to Calculate Simple Interest:

SI = (P × R × T) / 100

Where:

• SI = Simple Interest
• P = Principal amount (initial loan or investment)
• R = Annual interest rate (%)
• T = Time in years

📌 Example:

If you invest ₹50,000 at 5% per annum for 4 years:
SI = (50,000 × 5 × 4) / 100 = ₹10,000
Total Amount = ₹60,000

SI = (10,000 × 6 × 3) / 100 = ₹1,800
Total Value = ₹10,000 + ₹1,800 = ₹11,800
