About this calculator
Enter each day as HH:MM (for example, 08:30). Leave a day blank or enter 00:00 for no hours. Invalid clock times are rejected. This totals the entered week and applies the overtime threshold and multiplier you provide; it does not determine local wage-law rules.
Worked example
calculated with the default values below
Monday 08:00 · Tuesday 08:00 · Wednesday 08:00 · Thursday 08:00 · Friday 08:00 · Hourly rate 25 $ · Overtime after 40 h · Overtime multiplier 1.5 x Total hours 40.00 h · Regular hours 40.00 h · Overtime hours 0.00 h · Gross pay 1,000.00 $ · Average across five weekdays 8.00 h
Method and assumptions
H = Σ hᵢ; P = R × min(H,T) + R × k × max(H−T,0) Each day entry is parsed as hours + minutes ÷ 60. Enter each day as HH:MM (for example, 08:30). Leave a day blank or enter 00:00 for no hours. Invalid clock times are rejected. This totals the entered week and applies the overtime threshold and multiplier you provide; it does not determine local wage-law rules.

Frequently asked questions
Why is overtime paid only on hours past the forty hour threshold?
The model splits total weekly hours at the overtime-after setting, so with five 8 hour days the 40th hour is regular and any extra is overtime. At an overtime-after of 40 and multiplier 1.5, one extra hour at 25 dollars earns 37.50 instead of 25. Daily average divides the total by five, and gross pay adds regular and premium hours at your rate.
Which inputs and limits apply to Time Card Calculator?
Use the units shown beside each field. These are form limits, not recommended settings. Hourly rate: 0–10,000 $; Overtime after: 0–168 h; Overtime multiplier: 1–3 x H = Σ hᵢ; P = R × min(H,T) + R × k × max(H−T,0) Each day entry is parsed as hours + minutes ÷ 60.

What is a complete worked example for Monday = 08:00; Tuesday = 08:00?
Inputs: Monday = 08:00; Tuesday = 08:00; Wednesday = 08:00; Thursday = 08:00; Friday = 08:00; Hourly rate = 25 $; Overtime after = 40 h; Overtime multiplier = 1.5 x. Calculation: H = Σ hᵢ; P = R × min(H,T) + R × k × max(H−T,0). Results: Total hours = 40.00 h; Regular hours = 40.00 h; Overtime hours = 0.00 h; Gross pay = 1,000.00 $; Average across five weekdays = 8.00 h.
