How It Works & Formula

Mathematical Formula

Simple: I = P × r × t   |   Compound: A = P(1 + r/n)^(nt)

Simple interest grows linearly; compound interest grows exponentially by reinvesting earned interest.

📐 Step-by-Step Calculation Breakdown

Substituted values from your current calculation inputs:

Principal: ₹10000
Annual Rate (%): 5 %
Time (Years): 3 yr
Interest Type: compound

How to Use This Calculator

  1. Enter the principal amount.
  2. Choose simple or compound interest.
  3. Enter the annual rate and time period.
  4. Click Calculate.

Example Calculation

10,000 at 5% for 3 years simple = 1,500 interest. Compound monthly = 1,614.72.

Understanding the Results

Compound interest grows faster than simple interest, especially over long horizons.

Interest Calculator — Compare Simple vs. Compound Growth Frequencies

The Interest Calculator provides a flexible comparative engine that allows users to toggle seamlessly between simple interest and compound interest (monthly compounding). It computes the total interest accumulated, the final balance, and the Effective Annual Rate (EAR / APY) to reveal how frequency influences financial return.

Compare the Impact of Compounding over 5 Years:
Investing ₹5,00,000 at 8% annual return:
• Simple Interest yields: ₹5,00,000 + ₹2,00,000 = ₹7,00,000 (₹2,00,000 gain).
• Monthly Compound Interest yields: ₹5,00,000 × (1 + 0.08/12)⁶⁰ = ₹7,44,923 (₹2,44,923 gain).
• Compounding advantage: ₹44,923 extra return with zero additional capital invested.
