CrunchMyPay VS ShellNewHandler

CrunchMyPay's answer

Most paycheck calculators hand you a number and stop there. CrunchMyPay shows the formula it used, a worked example, and a link to the government page each rate came from — so you can verify the answer instead of trusting it. That also means we model the awkward details other calculators skip: New York's tax benefit recapture above $107,650, Washington's WA Cares and PFML premiums in a state that supposedly has "no income tax," and the gap between what payroll withholds from a bonus today and what the bonus actually costs you at tax time.

CrunchMyPay's answer

Three reasons. First, the numbers are current and sourced — 2026 federal tables, the current state tables, and a link to the IRS, SSA, DOL, GSA or state agency page behind each one. Second, the arithmetic is visible: every page shows its formula and a worked example, so you can check it by hand. Third, there is nothing in the way — no account, no email, no paywall, and every calculation runs in your browser rather than on our server.

CrunchMyPay's answer

People in the US who are paid hourly or on a salary and want a specific number: what an overtime week actually pays, what a raise leaves after tax, what a bonus really costs, how long a debt takes to clear. Alongside them, the people who get asked these questions for a living — payroll and HR staff, small business owners, freelancers pricing their rate, and anyone checking that a paystub is right.

CrunchMyPay's answer

Plain HTML, CSS and vanilla JavaScript, generated by a zero-dependency Node build script and served as static files by nginx. No framework, no client-side router, no tracking-heavy tag stack. The tax engine is a single self-contained JavaScript file that runs entirely in the visitor's browser, and it is covered by 205 hand-computed benchmark tests that run on every deploy.

CrunchMyPay's answer

CrunchMyPay came out of a specific annoyance: paycheck calculators that produce a confident number with no way to check it. Tax rules are full of details that quietly change the answer — a wage cap here, a phase-in there, a premium in a state that claims to have no income tax — and a calculator that hides its work gives you no way to tell whether it handled them. So the rule for this site is that every calculator shows its formula, its worked example, and the official source for each rate it uses. The list started with overtime and take-home pay and has grown to 44 calculators.
