Frequently Asked Questions
What is Simple Interest?
Simple Interest (SI) is the interest calculated on the principal amount only. Unlike compound interest, it doesn't include interest on previously accumulated interest. The formula is SI = (P × R × T) / 100, where P is principal, R is rate of interest per annum, and T is time in years.
How is Simple Interest different from Compound Interest?
Simple Interest is calculated only on the principal amount, while Compound Interest is calculated on both the principal and accumulated interest. This makes compound interest grow faster over time compared to simple interest.
When is Simple Interest used?
Simple Interest is commonly used in short-term loans, car loans, and some personal loans. Many financial institutions use simple interest for loans with shorter durations, typically less than a year.
How do I calculate the total amount with Simple Interest?
The total amount is calculated as: Total Amount = Principal + Simple Interest. For example, if you borrow ₹10,000 at 5% per annum for 2 years, SI = (10,000 × 5 × 2) / 100 = ₹1,000, and Total Amount = ₹10,000 + ₹1,000 = ₹11,000.
Can I use this calculator for both loans and deposits?
Yes! This Simple Interest Calculator works for any scenario involving simple interest - whether you're calculating interest on a loan you're taking, or interest you'll earn on a fixed deposit or investment.
