In this tutorial, we will learn how to calculate GST using python programming , it is a goods and service tax. It is applicable in India and it is paid by the customers to the government inorder to make gst calculation easy . Here this tutorial is created to know how much tax you are paying for a product.
To calculate the GST, first, compute the net GST amount by subtracting the original price from the net price that includes the GST. We use GST percent formula after calculating the net gst amount.
GST% formula = ((GST Amount * 100)/Original price)
Net price = Original price + GST amount
GST amount = Net price – Original price
GST% = ((GST amount * 100)/Original price)
round() function: round function rounds off to the nearest integer value.
We have the Net price, the original price, and the task is to calculate the GST percentage,
Input: Given original price = 520
Given Net price = 650
Output: The GST percent for the above given input net and original prices = 25.0%
Program to calculate GST
There are two ways to Calculate GST.
Method 1: Using Mathematical Formula (Static input)
- We define the
calculate_gstfunction as before. - We then provide static values for
original_priceandgst_rate. - We call the
calculate_gstfunction with these static values.
Finally, we print out the original price, GST amount, and total price including GST.
def calculate_gst(original_price, gst_rate):
gst_amount = original_price * (gst_rate / 100)
total_price = original_price + gst_amount
return gst_amount, total_price
original_price = 1000 # Example original price
gst_rate = 18 # Example GST rate
gst_amount, total_price = calculate_gst(original_price, gst_rate)
Output: print(f"Original Price: ${original_price:.2f}")
print(f"GST Amount: ${gst_amount:.2f}")
print(f"Total Price (including GST): ${total_price:.2f}")
Method 2: Using Mathematical Formula (User input)
- We define the
calculate_gstfunction as before. - We prompt the user to enter the original price and GST rate using the
inputfunction. - We convert the user inputs to floating-point numbers using
float. - We call the
calculate_gstfunction with the user-provided values. - Finally, we print out the original price, GST amount, and total price including GST in a single line.
def calculate_gst(original_price, gst_rate):
gst_amount = original_price * (gst_rate / 100)
total_price = original_price + gst_amount
return gst_amount, total_price
original_price = float(input("Enter the original price: "))
gst_rate = float(input("Enter the GST rate (%): "))
gst_amount, total_price = calculate_gst(original_price, gst_rate)
Output:
print (f"Original Price: ${original_price:.2f}") print(f"GST Amount: ${gst_amount:.2f}")print(f"Total Price (including GST): ${total_price:.2f}")
