In this presentation, I am going to peruse the opinion of the straightforward interest. Students in finance courses need good insight about the interest. So, let's peruse interest.

What is interest?

In simplest language, interest is the time value of money. For example, if I borrow from my friend today and I spend this bill to buy a fruit cake. If I return the same to my friend after 5 years, would my friend be able to buy the same fruit cake with after five years? Probably, not.

Things get costly and money loses value over time. The fruit cake I bought for today would probably cost or more after five years.

Therefore, is this reasonable to return the same estimate of money we borrowed merge years ago?

No, we have to add some extra money with the customary amount; we borrowed, to match the value of money with the inflation (inflation is the degree by which the things we use get expensive). The extra money we add with the customary estimate (Principle) is called the interest.

Formula to conjecture straightforward interest:

If the customary money borrowed is "P" and "R" is the rate of interest and the money is borrowed for "T" years then the interest "I" can be calculated as follows:

I = Prt

Some students don't understand the rate of interest. The rate of interest is just how much money will be added to 0 if it is borrowed for one year. For example, if the rate of interest is 8%, it means if I borrow 0 today then I have to payback 8 after one faultless year. Hence, I added for using 0 for a full year and which is interest.

For 0 the interest for the whole year at same rate is .

When the money borrowed is not 0 or it's multiple and some other weird estimate such as 3.58 then we have math recipe to deal with this. To find interest in this case the interest rate is converted into decimal and then multiplied with this weird estimate and with estimate of years too.

Consider a man borrowed 3.58 at a rate of 12%. conjecture the straightforward interest for 2 years.

In the given problem, Money borrowed P = 3.58

Rate of interest R = 12% = 0.12

Divide the %age rate by 100 to convert it into a decimal.

Number of years T = 2 years

Simple interest "I = Prt".

Substitute the values for "P", "R" and "T" in the above recipe to conjecture the straightforward interest "I" as shown below:

I = 733.58 * 0.12 * 2

I = 176.06

Hence the straightforward interest is 6.06 (rounded to nearest cent).
