Simple Interest Calculation

Simple interest is calculated only on the principal amount. It's commonly used for short-term loans and some deposit schemes.

Formula

Where SI = simple interest, P = principal amount, R = rate of interest per annum, T = time period in years

Example Calculation

Scenario:

Loan of ₹50,000 for 2 years at 10% p.a.

Calculation:

SI = (50,000 × 10 × 2) / 100

Result:

₹10,000 (Total repayment: ₹60,000)

Key Points

  • Interest is calculated only on the original principal amount
  • Total interest earned is directly proportional to time and rate
  • Simpler to calculate than compound interest
  • Generally yields lower returns than compound interest over the same period
