About MyTimeCardCalc

What this site does

Millions of Americans are paid by the hour, and most check the same questions every week: How many hours did I work? How much overtime am I owed? What will actually be in my paycheck? MyTimeCardCalc answers those questions with five free tools:

• Time Card Calculator — clock-in and clock-out times turned into hours, overtime and gross pay, with print and CSV export.
• Overtime Calculator — regular, overtime and double-time pay with state rules applied automatically (California daily overtime, Alaska, Colorado, Nevada, and the federal rule everywhere else).
• Time and a Half Calculator — instant 1.5× and 2× rates for any hourly wage.
• Salary to Hourly Calculator — convert pay both ways to compare jobs and offers fairly.
• Paycheck Calculator — take-home pay estimates using 2026 IRS brackets, Social Security, Medicare and state tax.

How we work things out

Our overtime rules follow the US Department of Labor's Fair Labor Standards Act and the published rules of state labor departments. Tax figures come from the IRS (for 2026, Revenue Procedure 2025-32) and the Social Security Administration. Every calculator page shows a worked example and explains the formula in plain English, and every page carries a "last updated" date. Where a figure is an estimate — state tax in graduated-bracket states, for example — we say so on the page.

Privacy is the feature

Every calculation runs in your own web browser, on your own device. Your hours, your pay rate and your paycheck numbers are never uploaded to a server — we couldn't see them even if we wanted to. Time card entries are stored only in your browser so the page remembers them when you come back.

Who runs it

MyTimeCardCalc is an independent project by Lattice Digital. Questions, corrections or ideas for new calculators are welcome — see the contact page.

Estimates only — not payroll, tax or legal advice. Your employer's official record is what counts.
