Understanding Simple Interest Calculator

Simple interest is calculated only on the original principal. It is common in some short-term loans and interest-payout deposits where interest does not get added back to earn more interest.

How this calculator works

Using SI = P × R × T ÷ 100, the calculator shows interest earned and the total amount payable or receivable over the chosen period.

Example

₹1 lakh at 8% for 3 years earns ₹24,000 simple interest, for a total of ₹1.24 lakh — less than the same money would earn under compound interest over longer periods.

Practical tips

  • Always check whether a product uses simple or compound interest.
  • For long tenures, compounding usually grows wealth faster.
  • Compare effective yields, not just headline rates.

Limitations

Many modern investments compound; do not assume simple interest unless the product terms say so.
