About

Clear financial math, explained.

Finance Outcomes is a free library of focused financial calculators built to show an answer, explain its meaning, reveal its drivers, and frame the implication.

What we build

Each tool combines a reusable deterministic TypeScript finance engine with a plain-language interface. The site is statically generated, and calculator inputs are processed in your browser.

Finance Outcomes provides a focused library of 11 financial calculators across investing, retirement, mortgages, trading, crypto, and everyday money decisions.

What we do not do

Finance Outcomes does not provide personalized recommendations, manage money, open accounts, execute trades, or fetch live market data. It does not use AI to produce numerical calculator results or driver rankings.

Principles

How trust is designed into the product

Transparent inputsEvery result is based on values and assumptions shown on the page.

Separated enginesFinancial logic stays independent from presentation code.

Known answersAutomated checks cover formulas, edge cases, and invalid inputs.

Neutral languageResults are scenarios and estimates—not forecasts or decision rules.
