What is Simple Interest?

Simple Interest (SI) is the easiest method of calculating the interest charge on a loan or the interest earned on a deposit. Unlike compound interest, where you earn interest on interest, simple interest is calculated only on the original principal amount.

Whether you are lending money to a friend, calculating returns on a fixed deposit, or planning a short-term loan, the Online Nli Simple Interest Calculator helps you get accurate results instantly.

The Mathematical Formula

The standard formula used to calculate simple interest is:

SI = (P × R × T) / 100

Where:

  • P (Principal): The original money invested or borrowed.
  • R (Rate): The annual interest rate (in %).
  • T (Time): The duration for which the money is lent or borrowed (in years).

Frequently Asked Questions (FAQ)

Q1: Can I calculate interest for a few days?

Yes! Unlike other tools, the Online Nei Calculator allows you to select "Days" from the dropdown menu. Simply enter the number of days (e.g., 45 days), and we will calculate the exact interest for that period.

Q2: What is the difference between Simple and Compound Interest?

Simple interest is calculated only on the principal amount. Compound interest is calculated on the principal amount plus any accumulated interest. Simple interest usually results in lower returns compared to compound interest over long periods.
