Free Work Hours Calculator

Last updated: October 16, 2026

Quick answer: Adding up a week's hours by hand — clock-in minus clock-out, minus the unpaid lunch, converted to the decimal hours payroll wants — is slow and error-prone, and one wrong conversion (writing 8:20 as 8.20 instead of 8.33) quietly shortchanges your pay. This free work hours calculator does the timesheet math for you: enter your daily start and end times with break minutes on the weekly grid, and it totals your hours live in both decimal and h:mm, splits regular vs overtime hours at your threshold, and estimates your gross pay line by line. Overnight shifts that cross midnight are detected automatically, and the whole week exports to CSV in one click. Everything runs in your browser — no signup, no upload, your timesheet stays yours.

How to Use the Work Hours Calculator

1. Enter your clock-in and clock-out times for each day you worked. Leave days blank for days off — empty rows are ignored, so a 5-day week and a 7-day roster both work.
2. Add your unpaid break minutes per day (lunch). Paid rest breaks stay in your total — only deduct breaks you're not paid for, or you'll undercount your hours.
3. Set your hourly rate, then tune the overtime rules: the weekly threshold (40 hours by default) and the multiplier (1.5× by default, the US FLSA standard). Uncheck the overtime split if your pay doesn't break it out.
4. Everything updates live as you type — total hours in decimal and h:mm, regular vs overtime hours, and the gross pay breakdown line by line.
5. Hit Copy summary for a paste-ready timesheet, or Download CSV to save the whole week for payroll, your manager, or your own records.

Why Use Our Work Hours Calculator?

• Full weekly timesheet grid — Monday–Sunday rows with start time, end time, and unpaid break minutes per day; totals update live with every keystroke in decimal hours (payroll format) and h:mm.
• Overnight shifts handled automatically — if clock-out is earlier than clock-in, the calculator assumes the shift crossed midnight and adds 24 hours. Night workers need no workaround.
• Configurable overtime split — the weekly threshold and multiplier are yours to set (40 h / 1.5× by default, the US FLSA standard); hours above the line are priced at the overtime rate automatically.
• Gross pay estimate, broken out — regular pay and overtime pay shown as separate lines, so the number on your pay stub never surprises you.
• One-click CSV + copy — download the whole week as a CSV for payroll or your records, or copy a plain-text summary to paste into an email or time-tracking app.
• 100% client-side and private — no signup, no upload, no account; your timesheet never leaves your browser.

Common Use Cases

• Hourly employees submitting timesheets: Fill the week's start/end times and lunch breaks in about a minute, download the CSV, and attach it to your timesheet email — totals in the decimal format payroll expects.
• Freelancers billing clients: Log hours per day across the week at your project rate, export the CSV as backup for the invoice, and copy the summary into the billing email.
• Managers spot-checking payroll: Re-run an employee's week in seconds to verify the hours and the overtime split before approving the timesheet.
• Night-shift workers: Overnight shifts that cross midnight calculate correctly without manual 24-hour arithmetic — enter 10 PM to 6 AM and move on.
• Job seekers comparing offers: Enter a typical week at two different hourly rates to compare true weekly gross pay, overtime included — a $2/hour gap can mean $100+ a week.

Work Hours Calculator vs Alternatives

• WorkCalcs' Work Hours Calculator: A clean single-shift calculator — start/end minus breaks, decimal plus h:mm, overnight shifts handled — with a genuinely useful how-to section. Ours adds what it lacks: the full weekly grid, the overtime split with a line-item pay estimate, and one-click CSV export — the payroll-ready layer.
• CalculatorPark's Work Hours Calculator: Daily and weekly hours with an overtime breakdown at 40h / 1.5× and solid worked examples. Ours adds the per-day timesheet grid with break minutes, a configurable overtime threshold and multiplier, and the pay estimate with CSV download.
• TimeRewards' Time Card Calculator: A time-card generator with break deductions and print output, aimed at employers processing payroll. Ours is the employee-side counterpart: a free weekly grid, pay estimate, copy plus CSV export — no print workflow needed.
• TimeCalculators.io's Work Hours Calculator: Weekly entry with base and overtime rate inputs and a pay breakdown — close in spirit to ours. Ours matches that and adds the CSV export, live-as-you-type totals, and the full Spanish and Portuguese pages.

Bottom line: if you want your week's hours, the overtime split, and your gross pay on one private page — with a CSV for your records — this page is built for that job. If you need approval workflows, team timesheets, or payroll integration, a dedicated time-tracking app is the natural next step.
