Simplified weekly model. Confirm pay with your employer.

This page uses a simplified federal-style weekly overtime model only. It is not FLSA compliance software, not a 50-state rules engine, and not legal advice. State and local overtime rules vary—confirm with your employer or a qualified advisor.

How it works

  1. Enter total weekly hours, or fill a simple day table so the week sums automatically.
  2. Set the overtime threshold (default 40) and multiplier (default 1.5×). Add an hourly rate only if you want a gross estimate.
  3. Read regular hours, OT hours, and optional estimated gross pay. Adjust numbers to match your card.

What this overtime calculator assumes

Under a common federal weekly idea, hours above a weekly threshold are paid at a higher rate (often time-and-a-half). This tool mirrors that pattern with numbers you control: threshold, multiplier, and optional rate.

It does not model daily overtime, double time tiers, tip credits, salaried exemptions, union contracts, or every state rule. Use it to sketch numbers before you check a paycheck—not as employer compliance software.

FAQ

How does this overtime calculator work?

Enter total weekly hours (or add daily hours so they sum), an overtime threshold (default 40), a multiplier (default 1.5), and optionally an hourly rate. Hours at or under the threshold count as regular; the rest as overtime. Gross pay is regular × rate + OT × rate × multiplier.

Is this based on FLSA or my state rules?

It uses a simplified federal-style weekly overtime idea. Many states and some employers also use daily overtime or other rules. This page is an estimate helper only—not FLSA compliance software or legal advice. State rules vary.

What is the difference between weekly OT and daily OT?

Weekly overtime looks at total hours in a workweek (often over 40 under federal rules). Daily overtime looks at hours in a single day (for example over 8 in some states). This tool only models weekly overtime.

Do I need an hourly rate?

No. Leave the rate blank to see regular and OT hours only. Add a rate if you want a rough gross pay estimate.

Is this payroll software?

No. It is a personal estimate helper. It does not open payroll accounts, submit timesheets, or give wage-and-hour legal advice.
