Overtime Calculator — Time and a Half After 40 Hours

Enter your weekly hours and rate. The federal rule does the rest: 40 hours straight time, everything above it at time and a half.

In short: apply the federal Fair Labor Standards Act rule — the first 40 hours in a workweek at your regular rate, every hour after that at 1.5× — and split your gross pay into regular and overtime lines.

How It Works — The Rule Behind This Calculator

The Fair Labor Standards Act (FLSA) requires most US employers to pay 1.5 times the regular rate for hours worked beyond 40 in a workweek. Three details matter:

Frequently Asked Questions

What is the federal overtime rate?

One and a half times your regular rate of pay (time and a half), owed for every hour over 40 worked in a single workweek, under the Fair Labor Standards Act.

I worked 12 hours in one day. Is that overtime?

Not under federal law by itself — daily hours do not trigger FLSA overtime. If your week stays under 40 hours total, no federal overtime is owed for that long day. California, Alaska, Colorado, Nevada and Oregon (in specific cases) do have daily overtime rules.

Can my employer give me time off instead of overtime pay?

Private-sector employers generally cannot substitute 'comp time' for overtime pay in a later week. Most public-sector employees can receive comp time at 1.5 hours per overtime hour under set rules.

Are salaried workers owed overtime?

Only if they are 'non-exempt.' Salary alone does not decide it — the exemption depends on duties and a salary threshold. If you are classified exempt, this calculator's rule does not apply to you; if you believe you are misclassified, that is a question for your state labor department.

Does overtime stack across two jobs at the same company?

Hours for the same employer are combined into one workweek total, even across roles or locations. Two different employers are counted separately.

Disclaimer: Estimates only — not payroll or legal advice. Your employer's payroll rules and state law control your actual pay. Figures are rounded for display; your pay stub and payroll department are the official record.

How it works — the formula

The calculator works in minutes. In quick mode it turns your total weekly hours into minutes, pays the first 2,400 minutes (40 hours) at your regular rate, and every minute after that at 1.5×. In day-by-day mode it first works out each day’s shift — clock-out minus clock-in, minus any unpaid break, with an overnight shift rolled into the next day — then walks through the week in order: minutes count as regular until the running total passes 40 hours, and the rest are overtime.

The formula:
Regular minutes = min(total weekly minutes, 2,400)
Overtime minutes = total weekly minutes − regular minutes
Gross pay = (regular hours × rate) + (overtime hours × rate × 1.5)

Worked example

You work Monday to Friday, 8:00 AM to 5:30 PM, with a 30-minute unpaid break, at $20/hour. Each day is a 9:30 span minus 0:30 of break = 9:00, so the week totals 45:00. The first 40:00 are regular (40 × $20 = $800.00) and the last 5:00 — all on Friday, where the running total crosses 40 — are overtime at $30.00 (5 × $30 = $150.00). Gross pay: $950.00. The quick mode gives the identical answer if you simply type 45 total hours.

Frequently asked questions

Does this calculator average two weeks together?

No, and neither does the federal rule it follows: each workweek stands on its own. A 30-hour week followed by a 50-hour week is 30 straight-time hours, then 40 regular plus 10 overtime hours — the two weeks are never blended into 80 regular hours. Run each week through the calculator separately.

How does the day-by-day grid decide which hours are overtime?

Chronologically. The calculator fills the 40-hour regular bucket in the order the hours are worked, and the day on which the running total passes 40 is the day that splits. In the worked example above, Friday’s 9 hours become 4 regular hours plus 5 overtime hours.

Are breaks taken off before or after overtime is worked out?

Before. On this page, the break minutes you enter for a day are deducted from that day’s shift first, and only the remaining paid minutes go into the weekly split between regular and overtime hours.

What if my shift runs past midnight?

Enter the clock-out time as you read it — for example, in at 10:00 PM and out at 6:00 AM. Because the out time is earlier than the in time, the calculator treats the shift as ending the next day and counts the full 8 hours.

Does the result include taxes?

No. The figure is gross pay — before taxes and any other withholdings. To estimate the separate federal deduction for the overtime premium in tax years 2025–2028, use the Overtime Calculator with Taxes on this site.
