2. Enter your numbers — everything is computed instantly in your browser; nothing is uploaded.
3. See the breakdown — regular pay vs. overtime vs. double time, with the exact rule applied.
4. Check your state — overtime rules differ by state (California daily overtime, 7th-day rules and more).

• State-aware — not a generic 1.5x multiplier. California's daily overtime, double-time after 12 hours, and 7th-day rules are built in, plus all 50 states.
• Sourced — every rule cites its statute (FLSA, state labor code) with a link to the official source.
• Private — calculations happen on your device. We never see your pay rate or hours.
• Current — rules verified September 2026; the OBBBA overtime deduction reflects 2025–2028 law.

Is overtime pay always 1.5 times my hourly rate?

Under the federal Fair Labor Standards Act (FLSA), yes — 1.5x for hours over 40 in a workweek. But some states add more: California requires daily overtime after 8 hours and double time after 12 hours.

Do I get holiday pay by law?

Federal law does not require private employers to pay extra for working on holidays. Holiday pay is a matter of company policy or union contract — our calculator shows what time-and-a-half would be if your employer offers it.

Is overtime really tax-free now?

No. The 2025 OBBBA law created a deduction (up to $12,500 single / $25,000 joint) on the half-time premium portion of overtime pay for 2025–2028 — not an exemption from tax. Our calculator explains the difference.

Are these calculators free?

Yes. Every calculator is free with no account required.

Do you store my pay information?

No. All math runs in your browser; your inputs never leave your device.
