Compound interest is the simple interest that is compounded annually i.e. the interest will be calculated and added to the principal amount every year. This increases the overall interest as compared to simple interest. There is a different mathematical formula to calculate the compound interest. Lets see with the an example,

Input:p=5, r=4, t=5 Output:1.083263

Compound Interest = Principle * (1 + Rate / 100)^time CI=5*(1+4/100)^5 CI=1.083263

#include <iostream> #include <math.h> using namespace std; int main() { float p, r, t, ci; p=5; r=4; t=5; ci = p * pow((1 + r / 100), t) - p; printf("%f", ci); return 0; }
