Interest Calculator – Simple & Compound Interest Made Easy

The Interest Calculator is an online tool that helps you calculate the interest on savings, loans, or investments. Whether it is Simple Interest (SI) or Compound Interest (CI), this calculator provides instant results for better financial planning.

What is Interest?

Interest is the cost of borrowing money or the reward for saving it. When you borrow money, you pay interest; when you invest money, you earn interest. Interest is usually calculated on the principal amount over a specific period at a defined rate.

Types of Interest

1. Simple Interest (SI)

Simple interest is calculated only on the principal amount:

SI = P × R × T / 100

• P = Principal Amount
• R = Annual Interest Rate (%)
• T = Time in years

2. Compound Interest (CI)

Compound interest is calculated on principal and accumulated interest:

CI = P × (1 + R/n)^(n×T) – P

• P = Principal Amount
• R = Annual Interest Rate (%)
• n = Number of compounding periods per year
• T = Time in years

How to Use Interest Calculator?

1. Enter the principal amount.
2. Select interest type: Simple or Compound.
3. Enter annual interest rate (%) and time period (years).
4. If compound, select number of compounding periods (monthly, quarterly, yearly).
5. Click Calculate to get interest amount and total value.

Example of Interest Calculation

Scenario 1 – Simple Interest:

• Principal: ₹50,000
• Rate: 8% per year
• Time: 5 years
• SI = 50,000 × 8 × 5 / 100 = ₹20,000
• Total Amount = 50,000 + 20,000 = ₹70,000

Scenario 2 – Compound Interest:

• Principal: ₹50,000
• Rate: 8% per year
• Time: 5 years
• Compounding: Quarterly
• CI = 50,000 × (1 + 0.08/4)^(4×5) – 50,000 ≈ ₹24,334
• Total Amount ≈ ₹74,334
