Let’s have a glance at how to find the loss percentage by using the C programming language.

**How to calculate the loss percentage?**

We can use the following formulae to calculate the loss percentage.

Loss = Cost Amount - Sold Amount Loss Percentage = (Loss * 100/Cost Amount)

## C Program to Calculate Loss Percentage

#include<stdio.h> void main() { double cp, sp, loss, loss_per; printf("Enter cost amount: "); scanf("%lf", &cp); printf("Enter sold amount: "); scanf("%lf", &sp); loss = cp- sp; loss_per = ((loss *100)/cp); printf("Loss Percentage: %lf\n", loss_per); }

**Output**

Enter cost amount: 30 Enter sold amount: 10 Loss Percentage: 66.666667
