Financial calculators
Seven calculators for the sums that come up most when investing. They are free, need no sign-up and run in your browser: no data is sent anywhere. Each one comes with the formula written out and a worked example in round figures, so the arithmetic can be redone by hand.

Valuing a company
With the figures of a real company
The calculators start from assumptions you enter. Real figures are on the company pages, with the accounts each one files with its regulator; what US companies pay per share is in dividends, and every term is in the glossary.
A calculation tool for informational purposes. It is not financial advice nor a recommendation to buy or sell, and its result depends entirely on the assumptions you enter.
