Share prices in the company have rocketed above the $50 mark meaning Twitter's value is over $24 billion (nearly £15bn).

ITV News has tweeted 60,599 times which, according to the calculator, means $279,128 (£173,651) is 'owed' to us.

However, popstar Justin Bieber - who was recently overtaken by Katy Perry in Twitter followers - is 'owed' a staggering $20,923,841 (over £13m) by the company.
