How does this overtime calculator work?

Enter an hourly rate, regular hours, and overtime hours. OTPayUS pays overtime at 1.5× and optional double-time at 2×, then shows the overtime premium and total gross. A California toggle splits each workday using daily OT after 8 hours and double-time after 12.

What is overtime premium?

Overtime premium is the extra pay above straight time. For time-and-a-half it is 0.5× the hourly rate times overtime hours. For double-time it is 1× the hourly rate times double-time hours.

Overtime hours (1.5×)Hours you already know are time-and-a-half.

Double-time hours (2×), optionalFederal FLSA does not require double-time. Use this for a union contract or a state rule.

California daily OTSplit each workday: 1.5× after 8 hours, 2× after 12, seventh consecutive day of work, then leftover weekly OT after 40.

Rough take-homeOptional. Applies one withholding percent to gross. Not a W-4 or paycheck.

01 — How the card is figured

What this overtime calculator shows

Straight time

Regular hours × hourly rate. Under the FLSA, that is usually the first 40 hours in a fixed 7-day workweek.

Time-and-a-half

Overtime hours × hourly rate × 1.5. The overtime premium is the extra half-time — 0.5 × rate × OT hours.

Optional double-time

Federal law does not require 2×. Enter double-time hours only if a contract or state rule (such as California after 12 hours) applies.

02 — Federal floor

FLSA overtime in one paragraph

The Fair Labor Standards Act requires covered, nonexempt employees to receive at least one and one-half times their regular rate for hours worked over 40 in a workweek. A workweek is 168 consecutive hours. Hours are not averaged across two weeks. Saturday, Sunday, or a holiday does not create overtime by itself. The official overview is DOL Fact Sheet #23.

Read the longer walkthrough on FLSA overtime basics, then the high-level exempt vs nonexempt page before you assume a salaried job skips overtime.

03 — States can pay more

California and other daily-OT notes

California

Daily 1.5× after 8 hours, 2× after 12, plus seventh-day premiums and leftover weekly OT after 40. Use the toggle on the calculator. California overtime note.

Alaska, Nevada, Colorado

Some states add daily overtime or a 12-hour daily trigger. Most states still follow the federal 40-hour week. Common state notes.

When rules conflict

If a state or local rule is more protective than the FLSA, the more generous rule generally controls for that employee. Confirm with the state labor department.

04 — Worked example

$20 an hour, 40 regular, 5 overtime

Straight time is $800. Time-and-a-half on five hours is $150. Total gross is $950. The overtime premium — the extra half-time — is $50. That is the number many payroll ledgers isolate when they ask “how much extra did OT cost?”

A 22% flat withholding guess on $950 is $209, leaving an estimated net of $741. That net is a napkin figure. It is not FICA, state tax, or a W-4.
