## C Program To Calculate Compound Interest

C Program to Calculate Simple Interest by Given Principle, Rate of Interest and Time - Simple interest is calculated by, sinterest=principle.time.rate/100 formula. Programming C Tutorials C Programs C Practice Tests New. Simple interest is calculated as (principal amount. time. rate) / 100. So, we need four variables that will store the value of the principal amount, time, rate, and interest. In this C program to calculate simple interest, We define four variables p, t, r, and interest which stores principal amount, time, rate, and interest respectively. Let us learn how to calculate simple interest in C programming language. We have enlisted two different methods to find simple interest and amount associated with it. The first method calculates simple interest without using function and the second method has a user – defined function to find the Simple Interest.

Let us learn how to write a program to calculate Compound Interest in C programming language. This C program to find compound interest takes in values of Principal Amount, ROI and Time Period from the user.

#### What is Compound Interest?

Compound Interest is the interest computed on the initial principal amount and also on the accumulated interest of previous periods of a deposit or a loan.

#### Formula To Find Compound Interest

**a = p (1 + r/n) ^{ nt}**

where,

** a** = value of the returns

** p** = Principal Amount

### Write A Program In C++ To Calculate Simple Interest Using Inline Function

** r** = Rate of Interest

### Write A Program To Calculate Simple Interest In C++ Terms

** n** = Number of times that Interest is compounded each year

### Write A C++ Program To Calculate Simple Interest Using Friend Function

** t** = Number of Years (Period)

#### Output

** p** = ₹ 5000

** r** = 10%

** n** = 12

** t** = 5

** Compound Interest** = ₹ 8226.54
