USD to INR Exchange Rate Calculator (Xoom, PayPal) Script in Python

Written by Pranshu Bajpai |  | LinkedIn

I frequently transfer money to India. For this reason, I find myself calculating amounts pertaining to USD to INR conversions using major remit websites such as the following:
  • Xoom
  • PayPal
  • Remitly
  • RIA Money Transfer
  • MoneyDart - Money2Anywhere
  • Trans-Fast
  • USForex Money Transfer
  • IndusInd Bank - Indus Fast Remit
  • State Bank of India
  • ICICI Money2India
  • Axis Bank - AxisRemit
  • Western Union

Since almost all of these websites offer more or less similar services, I usually choose the one that is offering me the best exchange rate. Having said that, I was quickly annoyed by having to visit each of these websites to compare them and determine the one that is offering the best USD to INR exchange rate on the present day. For this reason, I decided to write a Python web scrapping script that would go online, locate the exchange rates germane to all of these major websites and then show them to me for comparison.

Usage: python

Download: Github:

By default, it shows you the exchange rate grabbed from xoom (without any switch). Or, you can use '-x' or '--xoom' switch to do the same thing.

By using the '-a' or '--all' switch, you can view the current exchange rates corresponding to all major remit websites.

Initially, my 'usdtoinr' python script only displayed the current exchange rate from the major websites, but then I realized that it would be better if they could convert an amount in USD (US dollars) to an amount in INR (Indian Rupees). Accordingly, I added this functionality in the script. You can use the '-c' or '--convert' switch for this purpose.

As I started using PayPal, I added another function in my script that would show me an amount in USD (US dollars) converted to an amount in INR (Indian Rupees) and then deduct PayPal's fees of 4 percent from this amount to show me the money that someone would actually receive in India. To invoke this function, use the '-p' or '--paypal' switch.

Of course, '-h' or '--help' is to see the usage information.

That's all the functionality that is coded in the script at the moment since that's all I needed. With time, I may add more functions should I need them. As with all web scrapping scripts, the functionality of the script depends on the websites from where it is capturing the information pertaining to the exchange rates. If those websites change with time, it might result in the script breaking down. If that is the case, or if you want some other functionality added, feel free to modify the code.

Note: argparse is a nice library that you can use to allow for command line arguments or switches in your scripts.

Note: The ASCII text banner in the script has been generated with a utility called 'figlet'

  1. It's a well scripted page i like it...


  2. There are many sites available to transfer money to India, But Transferwise and Ria money as they pay the maximum with very good service. You can compare with sites like and Inr2day
