Check my pay stub — federal overtime
Enter hours you actually worked in the workweek, your base hourly rate, and the overtime dollars or overtime rate on your stub. This tool compares what you were paid on the OT line with a federal FLSA estimate at time and a half on hours over forty in the same workweek. It assumes your base rate is your regular rate (no shift differentials or bonuses in the same week—use the regular rate calculator for those). State daily overtime (for example California-style rules) is not included.
Federal FLSA only. If your employer pays straight time for all hours and shows only the half-time premium on the overtime line, this check compares the full 1.5× amount—so a correct half-time premium can look like a 0.5× multiplier here.

Federal overtime rules cited from DOL Fact Sheet #23, 29 CFR 778.104 (workweek), and 29 CFR Part 778. Special 8-and-80 rules for hospitals and residential care appear in 29 CFR 778.601 (FLSA section 7(j)). Paid vacation, holiday, and sick time when you did not work generally do not count as hours worked toward the forty-hour test (29 CFR 778.218(a)). Federal FLSA only—not legal advice.

FAQ
- Which overtime rule should I pick?
- Match the setting to your workplace policy or state default. When unsure, ask HR which threshold they use.
- Is overtime pay always 1.5×?
- Punch uses 1.5× for overtime hours and 2× for double-time hours (California-style daily mode). Weekly mode uses 1.5× on overtime hours only. Some roles or days may use different multipliers by law or contract.
- Do salaried employees use this?
- Salaried workers often track hours differently. This tool targets hourly-style time cards with optional rates.
- How many overtime hours is 45 hours in a week?
- Under weekly overtime after forty hours, forty-five total hours means five overtime hours and forty regular hours, before any rounding or break rules your employer applies.
- How do I calculate overtime pay after I know OT hours?
- Multiply overtime hours by your hourly rate and overtime multiplier (often 1.5). For dollar totals in one step, open the overtime pay calculator with your regular and OT hour buckets.
- Where are generic overtime word problems with answers?
- The overtime word problems hub shows worked examples (custom multipliers, biweekly hours, and varied weekly caps). The weekly overtime calculator uses the same maths for your own rate, multiplier, and hours.
- Is federal overtime calculated weekly or on the whole pay period?
- FLSA overtime is generally determined inside each workweek (29 CFR 778.104), not on a combined pay period total. Example: forty-five hours in week one and thirty-five in week two usually means five federal OT hours in week one only—not overtime after eighty hours combined. Special 8-and-80 rules may apply in hospitals and residential care (29 CFR 778.601).
- Do PTO or holiday hours count toward forty hours for overtime?
- For federal FLSA estimates, only hours actually worked in the workweek generally count toward the forty-hour threshold. Paid vacation, holiday, or sick time when you did not work is usually excluded (29 CFR 778.218(a)). State daily overtime and employer policies can differ.
- Is overtime taxed differently?
- Not when it’s withheld. Overtime is wages, and federal income tax, Social Security, and Medicare are withheld as normal per IRS Publication 15; your employer can’t reduce withholding for the new deduction unless you file an updated W-4 (IRS FS-2026-13 Q8). Separately, for tax years 2025 to 2028, you may be able to deduct the premium part of FLSA-required overtime (the ’half’ in time-and-a-half) on your federal return: up to $12,500 ($25,000 joint), reduced above $150,000 MAGI ($300,000 joint) (IRS overview). From 2026 it’s shown on your W-2 in box 12, code TT (FS-2026-13 Q6). Overtime paid only because of state law or a union contract (for example California daily overtime) doesn’t qualify, and state income tax treatment varies. Estimate yours with the no tax on overtime calculator.
How this calculator works
An Overtime Calculator splits your week into regular and overtime hours from real clock times, not from a guess at your schedule. HourPunch subtracts unpaid breaks, totals net time, and applies either a forty-hour weekly rule or California-style daily rules (1.5× over eight hours up to and including twelve in a day, 2× over twelve, seventh consecutive workday rules). When you enter an hourly rate, gross pay uses 1.5× on overtime and 2× on double-time hours.
Weekly mode pools Monday through Sunday before overtime starts at 1.5×. California-style daily mode applies daily premiums first, then may reclassify hours over forty in the week. Laws and contracts vary, so pick the rule that matches your workplace policy before you compare to a stub.
Union stewards and crew leads sometimes walk through a week row by row to see whether overtime came from one long day or from cumulative hours. Daily mode highlights hours over eight and over twelve in a single day; weekly mode catches a sixth day that pushes past forty even when no day looked extreme. Enter unpaid breaks so overtime reflects time on the job, not time in the break room off the clock.
Salaried exempt roles may not use these splits at all. This page targets hourly time cards where REG and OT lines appear on the stub. When only total hours are shown, you still need employer definitions before OT dollars make sense.
Seasonal rushes can push the same crew past forty hours one week and stay short the next; weekly mode captures that swing when daily mode would not. Print or export after you settle on a rule so you attach the same assumptions HR used when you follow up about a mismatch.
When overtime falls in a semi-monthly pay period (1st–15th or 16th–end), total REG and OT on the semi-monthly timesheet template. A single week with daily OT columns fits the weekly timesheet template when you only need seven rows.
For a full pay period on one screen, pair this with the biweekly time card calculator with lunch. Compare rounded punches on the 7 minute rule calculator or total a 24-hour grid on the military time card calculator.
Worked example
Say you work five days, 8:00 AM to 5:00 PM, with no breaks entered. Each day is nine hours, so the week totals forty-five hours. Under weekly overtime, forty hours stay regular and five are overtime. At ten dollars an hour, regular pay estimates to four hundred dollars and overtime adds five hours at fifteen dollars each, or seventy-five dollars, for four hundred seventy-five dollars gross before tax.
| Input or result | Example |
|---|---|
| Schedule | Mon–Fri 8:00 AM – 5:00 PM |
| Total hours | 45.00 |
| Regular / OT | 40.00 / 5.00 |
| Regular pay | $400.00 |
| Overtime pay | $75.00 |
| Estimated gross | $475.00 |
Worked example — check my pay stub (federal weekly)
You worked forty-four hours in the workweek at twenty dollars an hour. Your stub shows eighty dollars of overtime pay for four overtime hours. Federal FLSA overtime on four hours at time and a half is four times thirty dollars, or one hundred twenty dollars. The difference is forty dollars, and the implied multiplier on your base rate is 1.0× (straight time on the OT line), not 1.5×. Use the pay-stub checker below with your own numbers.
| Input or result | Example |
|---|---|
| Hours worked | 44 |
| Federal OT hours | 4 |
| Expected OT pay (1.5×) | $120.00 |
| OT pay on stub | $80.00 |
| Shortfall | $40.00 |
| Implied multiplier | 1.0× on base rate |
Hospital and nursing schedules that compare FLSA 8-and-80 to a standard forty-hour workweek belong on the healthcare overtime calculator. Homework-style problems that give a custom multiplier (such as 1.9×) and hours per week—not clock punches—belong on the weekly overtime calculator and overtime word problems pages. Those are generic maths tools, not state law.
Comp time and exempt salaried rules are not included; double time applies only in California-style daily mode. These totals are estimates for checking a pay stub, not payroll or tax advice. Enter your punches on this page or start from the main time card if you also need CSV export. Note which overtime rule you selected when you save a screenshot for HR so the image matches the policy you discussed.
People also ask
- How do I check if my stub paid time and a half?
- Use Check my pay stub below the punch grid: enter hours worked in the workweek, base rate, and OT dollars or OT rate from the stub. The tool compares your OT line to a federal FLSA estimate at 1.5× on hours over forty.
- How do I calculate overtime hours from my schedule?
- Enter real clock times and breaks, pick weekly (after 40 hours) or California-style daily rules, and read the regular, overtime, and double-time split.
- How much is 45 hours at $10 an hour with overtime?
- Forty hours at $10 is $400; five overtime hours at 1.5× add $75, for about $475 gross before tax in this estimate.
- Should I use daily or weekly overtime rules?
- Match your workplace policy. California-style daily mode applies 8h/12h/7th-day premiums; weekly mode pools the whole week before overtime starts at 1.5×.
