What is Simple Interest?

Simple Interest is very easy to understand. Imagine you have some pocket money. You give this money to your best friend because he needs help. Or you put this money inside a big bank to keep it safe. The bank or your friend will use your main money for some months or years. So, they must give you some extra cash for using your money. That extra happy cash is called Interest.
If the extra money is calculated only on the first main money you gave, it has the name Simple Interest. The first main money you start with is called the Principal Amount. The extra money percentage you get every year is called the Rate of Interest. The total duration you leave your money there is called Time (in years).

Frequently Asked Questions (FAQ)
What is the formula of Simple Interest?
The basic school formula for finding simple interest is very easy: $SI = (P \times R \times T) / 100$. Here, $P$ means Principal (starting money), $R$ means Rate (percent number), and $T$ means Time (number of years). Our tool uses this exact formula automatically.
Is Simple Interest different from Compound Interest?
Yes, they are different brothers! Simple Interest only gives you extra money on your first main deposit. But Compound Interest gives you interest on your interest also, so money grows much faster there. We have a separate tool for compound interest too!
Can I enter time in months in this calculator?
Our tool asks for time in years. If you have months, just change it to years first. For example, if you have 6 months, it means half year, so you should type 0.5 in the time box. If you have 12 months, just type 1.
Is my financial data safe on this website?
