Interest Calculator – Simple and Compound Interest

An interest calculator is a simple online tool that helps you determine how much interest will be earned on a specific principal amount over a given period and at a specific interest rate. It helps you quickly calculate both Simple Interest and Compound Interest in just a few seconds.

Types of Interest

We can calculate interest in 2 ways – Simple Interest and Compound Interest.

What is Simple Interest?

Simple Interest is calculated only on the original principal amount. Interest does not accrue on previously earned interest.

It is commonly used in:

• Short-term loans
• Basic savings calculations
• Personal borrowing

Simple Interest Formula:

SI=P×R×T/100

Where:

• P = Principal Amount
• R = Interest Rate
• T = Time Period

What is Compound Interest?

Compound Interest is calculated on both the principal amount and previously earned interest. This means your money grows faster over time.

It is widely used in:

• Fixed Deposits (FD)
• Mutual Funds
• Investments
• Savings Accounts

Compound Interest Formula:

A = P(1+r/n)^nt

Where:

• A = Final Amount
• P = Principal Amount
• r = Annual Interest Rate
• n = Compounding Frequency
• t = Time in Years
