About TryClearTally

TryClearTallyis an independent, ad-supported publisher of free financial calculators for US consumers. We built it because the math behind a mortgage, an auto loan, or a retirement projection shouldn't require a spreadsheet, a sign-up, or a sales call to a loan officer just to see the numbers.

Every calculator runs entirely in your browser. We don't collect the numbers you type in, store your inputs, or require an account — close the tab and nothing about your finances leaves your device.

How we keep the math honest

Each calculator is built on a standard, well-established financial formula — loan amortization, compound interest, progressive tax brackets — the same math lenders and financial institutions use, documented on our methodology pagewith links to primary sources like the IRS, the CFPB, and the Federal Reserve's FRED database.

Two things back that up in code, not just in promises. Every calculator has an automated test suite that checks its output against the standard formula, with expected values derived by hand rather than copied from the software. And the worked examples in our explainers are tested against the calculators themselves, so a number printed on a page can't quietly drift from what the tool actually returns. Where we show live interest rates, they come from FRED rather than being typed in by hand.

How our content is made

Our calculator explainers and FAQs are drafted with AI assistance, then reviewed for accuracy against the standard formulas and sources cited on each page before publishing.The math itself doesn't come from a language model: examples are produced by running the same formulas the calculators use. Content is reviewed by the ClearTally editorial team, and every calculator page shows when it was last reviewed.

What we don't do

We're not a lender, broker, advisor, or credit repair service, and we don't sell leads to one. Nothing here is personalized financial, legal, or tax advice — results are educational estimates, and the details a calculator can't see (fees, credit underwriting, your full tax situation) are exactly where a licensed professional earns their keep. See our financial disclaimer for the fine print.

The site stays free because it's supported by advertising. Ads are clearly separated from results and never influence what a calculator returns; our privacy policy covers how ad serving works.

Questions or corrections

If a number looks wrong, we want to know — accuracy reports go to the top of the pile. Email hello@trycleartally.com, use the contact page, or file it on the feedback page, where you can also see what we're building next and request a calculator we don't have yet.
