Four instruments, and what each of them refuses to do

Every figure here is arithmetic on numbers you type, and where an input is missing the instrument names it rather than guessing it.

01Valuation

For seeing how much of an enterprise value is the years you forecast and how much is the perpetuity behind the last of them.

Method behind it: the dcf lab case study

The rate that discounts every year and the perpetuity.
Growth of the perpetuity after the last forecast year.
Forecast free cash flows

Example figures, invented to show the arithmetic working; they value nothing.

Cash flows are in one unit of your choosing throughout; there is no net debt, no share count and no per share figure, because those would turn a decomposition into a price.

02Market size

For sizing a market twice, top down and bottom up, and reading the disagreement instead of averaging it away: every assumption is answered with the value it would have to take for the two to agree.

Method behind it: the market sizer case study

A label only; it changes no arithmetic.
Top down: a universe narrowed by factors
Bottom up: segments, each a product of drivers

Example figures, invented to show the arithmetic working; they size nothing.

03Runway

For the month the money runs out, and how many weeks of runway each planned hire costs.

No case study for this one; the method is printed under the chart.

The balance at the start of month one.
Everything that does not scale with headcount.
Fully loaded, per person, per month.
People on the payroll before any planned hire.
The tool computes nothing past this point and says so.
Planned hires
Expected income

Example figures, invented to show the arithmetic working; they plan nothing.

04Unit safety

For converting energy, mass and greenhouse gas units, and for being told exactly what is missing when a conversion has no answer.

Method behind it: the unitguard case study

A plain decimal: 0.1 means one tenth exactly.

Four conversions worth trying

Conversions you ran in this session

The list is not carried in the link; a shared link restores the quantity and the two units, and the verdict is recomputed from them.

05Method and constants

Three of the four instruments contain no constants and so have nothing to source; the only fixed values on this page are the global warming potentials the unit converter names in order to refuse to choose between them.

The global warming potentials the converter names and does not use

Carried over unchanged from unitguard, which names all four and picks none the unitguard case study on keremozdemir.de

Exact ratios used in the converter

These are ratios of molar masses and a definition, not measurements, so they carry no report and no horizon.
