The Cost Answer
Money questions, answered with a number at the top.
Not an essay with the answer buried in paragraph nine. Every figure names the document it came from and the date it was last checked, because on this kind of question being roughly right is the same as being wrong.
What this site answers
-
What is my paycheck actually worth?
Take home pay worked out line by line: federal tax, state income tax, Social Security, Medicare, and the disability and paid leave contributions six states take straight off a cheque and most calculators leave out.
-
What is this charge on my statement?
A line on a card statement that does not look like anywhere you have been. Most of them are a billing descriptor rather than a trading name, which is why searching the exact string usually returns nothing useful.

Should I recast my mortgage?
Putting a lump sum against the balance and keeping the term, against refinancing, against simply paying extra every month. Three different answers that depend on the numbers rather than on which one your lender mentions.

Where the figures come from
The one that is built so far covers 51 jurisdictions and one city. Every one was read at the state's own publication rather than copied from an aggregate table, and 49 of them cite a revenue department, a statute or an official form on the page itself. two states have published nothing for tax year 2026, and their pages say so rather than presenting an estimate as a fact.
The figures are also compared against an independent open source model of the United States tax system on every build. That comparison is how several rules were found that reading the tables had missed: a deduction that phases out in proportion, a state that swaps its whole rate table above a threshold, and two states where payroll tax is deductible. Where the two still disagree, the reason is written down next to the difference.
Nothing here is loaded from another website. No analytics, no trackers, no fonts fetched from somewhere else. That is a build rule rather than a promise: the privacy policy says it, and the build reads the published pages and fails if it stops being true.
A number to start with
On a $75,000 salary filing single, the gap between the best state to earn it in and the worst is $5,058 a year. That gap is the whole reason the first question gets asked, and it is the kind of thing this site exists to put a figure on rather than describe.
