What Quantus publishes

Quantus Tools & Intelligence publishes financial calculators and written analysis of the arithmetic behind them. At launch that is 10 calculators and 10 articles, all built around the same core idea: the time value of money, applied to saving, borrowing, retirement, tax treatment and protection.

The product is tool-first. Articles exist to explain the mathematics the calculators apply, not to pad the site with commentary. Every one of them shows worked figures, and those figures come from the same calculation modules that power the tools.

The standard every page is held to

A calculator that returns a number and nothing else is not finished. Every calculator here shows the formula it used, the assumptions it applied, at least one quantitative table, a worked example you can reproduce by hand, and an explicit statement of what the model does not do.

That last section is the one most tools omit, and it is the one that matters most. A projection that does not say where it stops being reliable invites people to rely on it further than they should.

Who this is for

It is for people making a decision who want to see the arithmetic rather than be handed a conclusion: whether a savings plan is on track, what extra principal actually saves, whether deferring tax is worth it, how much coverage a household's obligations imply.

It assumes no financial background, but it does not simplify by hiding. Where something is genuinely uncertain — a return, an inflation rate, a future tax rate — the page says so and lets you test it rather than presenting a single confident number.

What Quantus is not

It is not an advice service. Nothing here is investment, tax, legal or insurance advice, and no calculator can account for the circumstances that make a decision personal.

It is not a forecaster. Every projection is arithmetic applied to assumptions you supply. Where a page shows a scenario band, that band exists to show how much the result depends on an assumption, not to assign probabilities to outcomes.

It is not a lead-generation funnel. Calculations run in your browser, results are never withheld pending an email address, and no input is transmitted to or stored by this site.

How the site is built

The site is a statically rendered Next.js application. Explanatory content, tables and formulas are server rendered and ship no JavaScript; only the interactive calculators, the search box and the navigation menu run in the browser.

There is no CMS, no database and no third-party search service, because the content is small, structured and versioned in the repository. One registry defines every page, its metadata, its keywords and its contextual links, and the navigation, indexes, search index, sitemap and validation scripts all read from it.

The methodology page describes the calculation architecture and testing standard in detail.

Corrections and contact

Corrections are welcome and are treated as defects. A wrong number is fixed in the calculation module, covered by a test that fails without the fix, and reflected in any worked example that quoted it.
