1. Simple Interest Calculator:

The Simple Interest Calculator helps you calculate the interest on any given principal amount, rate of interest, or time period. It is an essential tool for anyone who deals with loans or investments that follow simple interest formulas.

What you can calculate:
- Principal (P): The initial amount invested or loaned.
- Rate (R): The annual interest rate (in percentage).
- Time (T): The time period for which the interest is calculated (in years).
- Interest (I): The amount of interest accrued over the time period.

With this feature, users can easily determine any missing variable in the simple interest formula:
Interest (I) = (Principal (P) * Rate (R) * Time (T)) / 100

Whether you have the principal and need to calculate the interest, or you have the interest and want to find the time or rate, this calculator can handle it all. This is an invaluable tool for anyone who wants to understand the basic workings of financial transactions that use simple interest.

2. Compound Interest Calculator:

The Compound Interest Calculator is designed for users dealing with more complex financial scenarios where interest is calculated on the principal, as well as on accumulated interest over time. This tool is perfect for users who want to calculate returns on savings, investments, or loans with compound interest.

The compound interest formula is:
A = P * (1 + R/n) ^ (n * T)

- Principal (P): The initial investment or loan amount.
- Rate (R): The annual interest rate (in percentage).
- Time (T): The duration for which the interest is compounded.
- Compound Frequency (n): How often the interest is compounded, such as annually, semi-annually, quarterly, or monthly.
- Interest (I): The total compound interest accrued.
- Amount (A): The total amount after interest is added to the principal.

This calculator will help you understand how different compounding frequencies (annually, monthly, etc.) can impact your investment or loan over time. It’s ideal for calculating things like retirement savings, investment growth, or loans that compound over time.

Download the Interest Calculator App today and take the guesswork out of financial calculations! Whether you're calculating simple interest on a loan or determining how your savings will grow with compound interest, this app is your go-to tool. Get started now and make better financial decisions with ease!

★☆☆☆☆ Tanmay Kundu · Mar 29, 2019
You have putted wrong formula in your App. When I calculate Compound Interest in P=29000, Rate= 6.35%, Compound Quarterly, Time = 90 Days, your app result I= 462. But, if you put the same data in Compound Interest formula I=454. My bank also gave ₹454 interest for the same data. I also sent you an email with screenshots. Update your app with correct formula.
