Track your weekly hours without spreadsheets. Enter your clock-in, clock-out, and lunch break for each day of the week. The calculator splits your total into regular hours (up to 40) and overtime hours (above 40). Add an optional hourly rate to see your estimated gross pay, including overtime at 1.5×.

How it works

2 min read

What is overtime?

Overtime is any work hours beyond 40 in a standard workweek, typically compensated at 1.5 times your regular hourly rate. For example, 45 hours at $20/hour means 40 regular hours ($800) plus 5 overtime hours at $30/hour ($150), totaling $950 gross pay for the week.

How It Works

This calculator uses decimal hours (e.g., 9.50 = 9:30 AM) for simplicity. For each day, it subtracts the clock-in time from the clock-out time, then deducts the lunch break.

daily_hours = (clock_out − clock_in) − (lunch_minutes / 60)

Negative or zero values (days off, blank entries) are treated as 0 hours. The seven daily totals are summed into a weekly total.

weekly_total = Σ daily_hours  (Mon–Sun)

Regular vs. Overtime

Under the Fair Labor Standards Act (FLSA), non-exempt employees must receive overtime pay at 1.5× their regular rate for all hours over 40 in a single workweek.

regular_hours = min(weekly_total, 40)
ot_hours      = max(weekly_total − 40, 0)

Gross Pay Formula

If you enter an hourly rate, estimated gross pay is:

gross_pay = (regular_hours × rate) + (ot_hours × rate × 1.5)

Example: You work Mon–Fri, 9 AM to 6 PM with a 30-minute lunch each day. That's 8.5 hours/day × 5 days = 42.5 total hours. At $22/hr:

MetricValue
Total hours42.50 h
Regular hours40.00 h
Overtime hours2.50 h
Regular pay$880.00
OT pay (×1.5)$82.50
Gross pay$962.50

Limitations

  • Daily OT not calculated. Some states (CA, AK, NV) require OT after 8 hours in a single day. This calculator uses only the federal 40-hr/week threshold.

  • Time entered in decimal format. If your clock reads 9:45, enter 9.75, not 9.45.

  • Pre-tax only. Gross pay does not account for federal/state income tax, FICA, or any other deductions.

  • Salaried / exempt workers. The FLSA overtime rule applies to non-exempt hourly workers; salaried-exempt employees are generally not entitled to OT.

  • Shift spanning midnight. If clock-out is earlier than clock-in (e.g., in=22.00, out=6.00), the calculator will return 0 for that day. Use total elapsed hours manually in that case.
  • Frequently asked questions

    How do I enter 7:45 AM and 5:15 PM?

    Use decimal hours: 7:45 AM = 7.75, 5:15 PM = 17.25. To convert minutes to decimals, divide minutes by 60 (e.g., 45 min ÷ 60 = 0.75). Enter the 24-hour decimal equivalent for PM times (1:00 PM = 13.00, 5:30 PM = 17.50).

    What is the federal overtime threshold in 2026?

    Under the Fair Labor Standards Act (FLSA), the standard overtime threshold remains 40 hours per workweek for non-exempt employees. Hours beyond 40 must be paid at a minimum of 1.5× the regular rate. Some states set stricter daily thresholds.

    Does this calculator handle California daily overtime rules?

    No. California requires overtime after 8 hours in a single workday and double time after 12 hours. This calculator applies only the federal 40-hr/week rule. California workers should use a state-specific tool or consult their employer's payroll system.

    Can I leave days blank if I didn't work?

    Yes. If both clock-in and clock-out are 0 (or left at their defaults of 0), the day contributes 0 hours to the weekly total. Days off, holidays, and sick days should simply be left at 0.

    Is gross pay the same as net (take-home) pay?

    No. Gross pay is earnings before any deductions. Your actual take-home pay will be lower after federal and state income tax withholding, Social Security (6.2%), Medicare (1.45%), and any voluntary deductions like health insurance or 401(k) contributions.

    What if my shift crosses midnight (e.g., 10 PM to 6 AM)?

    Decimal time arithmetic doesn't handle midnight crossings automatically. For overnight shifts, enter total elapsed hours manually: a 10 PM–6 AM shift is 8 hours, so enter clock-in=0 and clock-out=8 with no break, or add those hours to a single-day entry.

    How is the lunch break deducted?

    Enter the unpaid break in minutes. The calculator converts it to hours (minutes ÷ 60) and subtracts from the raw clock-out minus clock-in difference. A 45-minute lunch = 0.75 h deducted from that day's hours.

    Does this include holiday or weekend premium pay?

    No. Under federal law, weekend and holiday premium pay are not required unless the hours push the weekly total above 40. Any voluntary premium your employer pays must be calculated separately.

    What is the FLSA minimum wage for 2026?

    The federal minimum wage remains $7.25/hr as of 2026. Many states and cities have higher minimums. This calculator does not enforce a minimum — enter whatever rate applies to your situation.

    Can salaried workers use this calculator?

    Salaried-exempt employees are generally not entitled to overtime under the FLSA regardless of hours worked. However, salaried non-exempt workers are. If you're unsure of your classification, check with your HR department or review DOL guidance.
