Week math

Overtime hours calculator

45 hours in a week, overtime after 40

5 hours

40 regular + 5 overtime. Change the week total or the 40-hour line below.

Type hours and minutes for the week you already worked. Overtime here is only hours past the line you set. Your job may use a different week, daily OT, or no OT at all.

Hours over 40 here are only this week's arithmetic. Overtime law is not the same everywhere and this is not legal advice.

How this split is counted

Regular hours = the smaller of the week total and the overtime line (usually 40). Overtime hours = whatever is left. 45.00 − 40.00 = 5.00. A 40-hour week with 0 overtime is 40 regular. This is not FLSA, a union rule, or your state’s daily overtime.

Is overtime always after 40 hours? No. Some jobs use 8 in a day, 37.5, or another number. Change the line.

Does this include 1.5× pay? No. Extra pay is a rate. This page only splits hours.

Can I use a 37.5 hour week? Yes. Set overtime after to 37.5.
