About TrueFiHub

Our Mission

TrueFiHub exists to answer a specific kind of question — what a payment works out to, how long a balance takes to clear, what a figure converts to — accurately, immediately, and without asking anything of you first.

No account, no email address, no paywall, no usage limit. Every calculator is free, and the arithmetic runs in your browser rather than on our servers, so the numbers you type stay with you. That is a deliberate design choice, not a limitation we plan to remove.

The library currently holds 817 calculators across 23 categories — mortgages, loans, taxes, investing and retirement alongside unit conversion, health, statistics, construction and date arithmetic. How each one is built and checked is set out on our methodology page.

What We Offer

• 817 Free Calculators covering loans, mortgages, taxes, investments and crypto — plus unit conversion, health, science, construction, statistics and date arithmetic
• The formula on the page, for nearly every calculator, so the result is checkable rather than something you have to take on trust
• Mobile-Optimized tools that work seamlessly on any device
• Stated assumptions and limits on every calculator, because what a tool ignores matters as much as what it computes
• No sign-up and no stored history — open a page, get an answer, close the tab

How the site is funded

TrueFiHub may carry advertising and affiliate links, and may earn a commission when a reader follows one of those links to a third-party product. That is set out in full in our disclaimer and privacy policy.

What that funding does not do is change a result. A calculator applies its formula to the numbers you enter and nothing else: there is no product ranking, no recommendation engine, no lender scoring, and no rate weighted in your favour or anyone else's. We also do not fetch live rates, prices or tax tables — every rate in a calculation is one you typed in yourself, which is why a result is only as current as the figures you bring to it.

What we are not

We are not a financial adviser, a lender, a broker, or a substitute for any of them. Nothing on this site is financial, legal or tax advice; a result is an estimate for planning and learning, never a quote or an offer. Where a decision carries lasting consequences, take the numbers to a qualified professional who can see your whole situation — a calculator cannot.

We are also candid about depth. Coverage is wide, and the amount of written explanation varies from page to page: some calculators carry a worked example and their own questions, others currently show the formula and the calculator alone. We would rather a page say less than pad itself with text that helps nobody, and we are filling those gaps category by category.

Tell us when we are wrong

A calculator that returns the wrong number is the most serious problem this site can have, and corrections come before new tools. If a result does not match what you expect, send us the calculator, the exact inputs, the result you got and the result you expected — that is enough for us to reproduce it.
