Calculating easy curiosity is straightforward utilizing the method – ** SI = P x R x T**, the place P is the principal quantity, R is the Annual Curiosity Fee, and T is the Time interval (in years).

### Compound Curiosity Fee:

Compound Curiosity, often known as “curiosity on curiosity,” is a technique the place the curiosity earned is added to the principal quantity, and future curiosity calculations are based mostly on this new principal. Right here, the curiosity is earned on each the preliminary principal and the accrued curiosity from earlier intervals.

Now, let’s take a look at how you can calculate easy curiosity.

The easy curiosity method is:

SI = P x R x T

The place,

P = Principal quantity (the preliminary amount of cash)

R = Annual rate of interest (expressed as a decimal)

T = Time interval (in years)

Let’s take a look at an instance

Suppose you make investments ₹1000 at an annual rate of interest of 5% for 3 years.

So right here, the principal quantity (P) is ₹1,000, the annual rate of interest (R) is 5% or 0.05, and the time interval (T) is 3 years.

Utilizing these values, you’ll be able to calculate the rate of interest,

SI = 1000 x 0.05 x 3

So, the easy curiosity (SI) earned over 3 years is ₹150.

To seek out the overall quantity (A) after the curiosity is added, use the method:

A = P + SI

A = 1000 + 150

Subsequently, the overall quantity after 3 years shall be ₹1,150.

### Compound Curiosity:

The compound curiosity calculation contains the principal quantity, the rate of interest, the variety of instances the curiosity is compounded per yr, and the overall variety of years the cash is invested or borrowed.

The compound rate of interest method is:

The place:

A = The longer term worth of the funding/mortgage, together with curiosity

P = Principal quantity (preliminary amount of cash)

R = Annual rate of interest (in decimal type)

n = Variety of instances curiosity is compounded per yr

T = Time interval (in years)

Let’s take a look at a compound rate of interest instance to know this higher.

Suppose you make investments ₹1000 (P) at an annual rate of interest of 5%, compounded quarterly (n=4), for 3 years (T).

Utilizing these values within the method, you’re going to get

Fixing this equation, you’re going to get

A = 1161.62

So, the long run worth of the funding/mortgage after 3 years shall be ₹1,161.62.
