Hours Calculator
Calculate work hours and overtime pay
About the Hours Calculator
Working out a timesheet by hand — start time, end time, minus the lunch break, across several days — is exactly the kind of arithmetic that invites mistakes. This calculator adds it all up: enter each day's start and end times and break, and it totals your hours, splits them into regular and overtime, and can even compute your pay.
Hourly workers use it to check a paycheck, freelancers to total billable time, and managers to tally a team member's week. It handles overnight shifts where the end time is earlier than the start, deducts break minutes per day, and applies a 1.5× rate to hours over your overtime threshold when you enter an hourly rate.
How to Use the Hours Calculator
- Add a row for each day, entering its start time, end time, and break in minutes.
- Set your weekly overtime threshold (40 hours by default).
- Optionally enter your hourly rate to calculate pay.
- Read the total, regular, and overtime hours, plus regular, overtime, and total pay if a rate was given.
Why Use ToolForge’s Hours Calculator
- It tracks multiple days at once and sums the week, rather than making you total each day separately.
- It detects overnight shifts (end time before start) and adds the wraparound automatically, and deducts each day's break.
- It splits hours into regular and overtime at your threshold and applies a 1.5× overtime pay multiplier when you add a rate.
- All calculations run in your browser, so your work and pay details stay private.
Frequently Asked Questions
How does it handle an overnight shift?
If the end time is earlier than the start time — say a shift from 22:00 to 06:00 — the calculator recognizes it crosses midnight and adds 24 hours so the duration comes out correctly rather than negative.
How is overtime calculated?
Hours up to your weekly threshold (40 by default) count as regular; anything above counts as overtime. If you enter an hourly rate, overtime is paid at 1.5 times that rate, which is a common standard, while regular hours are paid at the base rate.
Are breaks subtracted from my hours?
Yes. The break minutes you enter for each day are deducted from that day's worked time, so an 8-hour shift with a 30-minute unpaid break counts as 7.5 hours.
Does it calculate pay automatically?
Only if you enter an hourly rate. Leave it blank and the calculator just totals your hours; add a rate and it works out regular pay, overtime pay at 1.5×, and the combined total.
