Calculators
Each one prints its formula, defines every input, names where in a filing the input comes from, and shows the working rather than only the answer. Free, no account, no email. Where an input is an estimate rather than a filed figure, the page says so instead of picking a default and hoping you do not notice, and where a figure cannot be computed it prints the reason instead of a zero.
What a business might be worth
Three ways of putting a number on a company, and one page whose whole subject is that they disagree.
Intrinsic value calculator
Three models rather than one answer, with what each assumes printed beside it and no average taken across them.
DCF calculator
The two-stage valuation engine the workbench itself runs, with the year ladder printed and the terminal value shown as a share of the answer.
Graham Number calculator
Where the 22.5 comes from, what the test was screening for, and the two cases where the formula returns nothing at all.
What capital costs and what it earns
The rate a business pays for money, and the rate it makes on the money it has.
WACC calculator
Weighted average cost of capital from the five inputs it actually takes, with what each one means, where to find it, and what the result cannot tell you.
ROE and ROIC calculator
Both returns on capital from seven filed lines, the gap between them read as gearing, and negative equity answered with n/m.
Growth and what a shareholder receives
How fast a figure moved, and what the shares actually pay against a price.
CAGR calculator
A compound annual growth rate forwards and backwards, and a measure of how much of it one good year produced.
Dividend yield calculator
Trailing and indicated yield from one price, why they disagree, and why an unknown dividend is not a zero.
A calculator is arithmetic, not advice. None of these is a view on any security, and none of them is a valuation: they compute one input to a decision that is yours. Nothing typed into any of them is sent anywhere, stored or logged.
