Work Hours Calculator

What it does

Enter clock-in and clock-out times (with a break deducted, if applicable) across a day or a full week, and the Work Hours Calculator totals the hours worked, splits out overtime if you’ve set a standard threshold, and applies an hourly rate if you want a pay total alongside the raw hours — useful for freelancers building an invoice, hourly employees double-checking a paycheck, or anyone reconstructing a timesheet after the fact.

Why local processing matters here

A filled-in timesheet says more than it looks like — exact start and end times reveal a real daily schedule, and adding an hourly rate turns it into actual income data. This is exactly the kind of record that sometimes gets pulled up during a pay dispute with an employer, or while preparing an invoice for a client who hasn’t seen your rate yet. None of that needs to sit on a server to get totaled correctly — the calculation happens entirely in your browser, so the hours and rate you enter stay with you.

Enter each day’s start time, end time, and any unpaid break, and the tool totals hours automatically as you go — add a full week’s worth of entries to get a weekly total, with overtime broken out separately once you set the standard hours threshold (commonly 8 hours/day or 40 hours/week, adjustable for different arrangements). If you’re calculating pay rather than just hours, add your hourly rate and the tool applies it to both regular and overtime hours, using whatever overtime multiplier applies in your situation.

FAQ

How do I handle a shift that crosses midnight?

Enter the clock-out time as being on the next day rather than trying to force it into a single-day format — the tool detects an overnight shift automatically when the end time is earlier than the start time and calculates the duration correctly across the date boundary.

Does this account for different overtime rules in different places?

The overtime threshold and multiplier are both adjustable, since rules vary significantly by location and employment type — set them to match your specific situation rather than relying on a single default that may not apply.

Can I calculate a full pay period, not just a single week?

Yes — enter each day across the full period and the tool totals both hours and pay across as many days as you add, useful for biweekly or semi-monthly pay periods.

What if I need to subtract multiple breaks in a single shift, not just one?

Add each break separately if your shift includes more than one — the tool sums all entered breaks and deducts the total from the gross shift duration.

If the end goal is turning these hours into an actual client invoice with multiple currencies or line items, the Invoice Generator handles that next step directly.
