Federal regular rate — shift diff, bonus, or two rates
When shift differentials, nondiscretionary bonuses, or two hourly rates apply in one workweek, federal overtime generally uses a regular rate (weighted average where needed, unless an agreed alternative under FLSA section 7(g)(2) applies), then at least 1.5× that rate on hours over forty actually worked. Estimated gross equals straight-time earnings plus the half-time OT premium (0.5 × regular rate × OT hours).
Workweek inputs
Regular rate & OT
- Straight-time earnings
- $660.00
- Regular rate (this workweek)
- $13.20/hr
- Overtime hours (over 40)
- 10
- OT premium (0.5 × regular rate × OT hrs)
- $66.00
- Estimated gross
- $726.00
Straight-time ($660.00) + OT premium ($66.00) = gross ($726.00). Full FLSA OT line at 1.5× regular rate would be $198.00 on 10 OT hours.
Regular rate methods cited from DOL Fact Sheet #56A, 29 CFR 778.115 (weighted average for two rates, unless an agreed alternative under FLSA section 7(g)(2) applies—see 29 CFR 778.415–778.421), 29 CFR 778.207(b) (shift differentials), and 29 CFR 778.209 (bonuses). Federal FLSA only—not legal advice.
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
- How is overtime pay calculated?
- Regular pay is hourly rate multiplied by regular hours. Overtime pay is hourly rate multiplied by overtime hours multiplied by the overtime multiplier (commonly 1.5). Total pay is regular pay plus overtime pay. Example: $20 per hour with 40 regular hours and 5 overtime hours at 1.5× is $800 regular + $150 overtime = $950 total before tax.
- What is time and a half on $18 an hour?
- Time and a half means the overtime multiplier is 1.5× the base rate. On $18 an hour, each overtime hour pays $27 in this estimate ($18 × 1.5). Regular hours still pay $18 each.
- How do I get overtime hours before using this calculator?
- Use the overtime calculator or main time card with your real clock times and breaks. It splits regular versus OT hours; then enter those buckets here with your hourly rate for gross pay lines.
- Where can I solve homework-style overtime word problems?
- The weekly overtime calculator accepts any multiplier and computes OT per week, and the overtime word problems page lists worked examples with step-by-step maths.
- Does PTO or holiday pay count toward the 40 hours for federal overtime?
- Under federal FLSA, overtime is generally based on hours actually worked in the workweek. Paid vacation, holiday, or sick time when you did not work usually does not count toward the forty-hour threshold (29 CFR 778.218(a)). State laws may differ; this page describes federal rules only.
- Is overtime calculated per week or per pay period?
- Federal FLSA overtime is generally calculated per workweek—a fixed seven-day period (29 CFR 778.104)—not by averaging hours across a biweekly or semimonthly pay period. Employers generally cannot wait until eighty hours in two weeks to start overtime if you worked more than forty in either week. Hospitals and residential care may use special 8-and-80 rules (29 CFR 778.601; FLSA section 7(j)).
How this calculator works
An Overtime Pay Calculator turns regular and overtime hour buckets into dollar amounts. HourPunch multiplies regular hours by your base hourly rate and overtime hours by base rate times your overtime multiplier—commonly one and a half. It adds those lines for estimated gross pay before tax. You supply the hours; it does not read clock punches directly.
Blank hour fields count as zero so you can model partial entries. Without a valid hourly rate, pay lines stay empty. Change the multiplier when policy pays double time or another factor. Bonuses and reimbursements are outside this tool.
Some stubs list regular and overtime hours separately without showing the dollar math. Enter those buckets with your base rate to see if gross matches before tax. Change the multiplier when your employer pays double time on Sundays by typing two point zero instead of one point five.
Commission-only or tipped roles may still show a base hourly line for overtime premiums—use that base here, not total take-home. If you only know total hours and total gross, derive the hour split from a time card first, then return to this page for dollars.
Direct deposit day is easier when you know how regular and overtime lines combine on the stub. This layout mirrors many pay statements: base hours, premium hours, then gross. Use the federal regular rate section below when shift differentials, nondiscretionary bonuses, or two hourly rates in one workweek change the overtime base rate.
Payroll portals sometimes show year-to-date overtime dollars separately from current period hours; this tool focuses on one period at a time. Enter whole or decimal hour buckets exactly as the stub labels them for the closest gross comparison before you call payroll.
Worked example — time and a half
At twenty dollars an hour with forty regular hours and five overtime hours at a one-and-a-half multiplier, regular pay estimates to eight hundred dollars. Overtime pay estimates to five times twenty times one point five, or one hundred fifty dollars. Total estimated gross is nine hundred fifty dollars before deductions. Compare those three lines to the REG, OT, and gross rows on your stub.
| Input or result | Example |
|---|---|
| Hourly rate | $20.00 |
| Regular hours | 40 |
| Overtime hours | 5 |
| Multiplier | 1.5× |
| Regular pay | $800.00 |
| Overtime pay | $150.00 |
| Total gross | $950.00 |
Worked example — two rates (weighted average)
In one federal workweek an employee works thirty-five hours at twelve dollars an hour and fifteen hours at sixteen dollars an hour (fifty hours total). Straight-time earnings are four hundred twenty plus two hundred forty, or six hundred sixty dollars. The regular rate is six hundred sixty divided by fifty, or thirteen dollars and twenty cents an hour. Gross pay is straight-time earnings plus the half-time OT premium: ten overtime hours × 0.5 × $13.20 = $66.00 premium, so $660.00 + $66.00 = $726.00 before tax (the full 1.5× OT line on those hours would show $198.00).
| Input or result | Example |
|---|---|
| Straight-time earnings | $660.00 |
| Regular rate | $13.20/hr |
| Overtime hours | 10 |
| OT premium (0.5 × RR × OT hrs) | $66.00 |
| Estimated gross | $726.00 |
Worked example — shift differential
Forty-four hours at a ten-dollar base rate include sixteen night hours with a one-dollar-fifty shift differential (eleven fifty straight time on those shifts). Straight-time pay is four hundred sixty-four dollars. The regular rate is four hundred sixty-four divided by forty-four. The OT premium is four hours × 0.5 × that regular rate, or $21.09, so gross is $464.00 + $21.09 = $485.09.
| Input or result | Example |
|---|---|
| Straight-time earnings | $464.00 |
| Regular rate | $10.5455/hr |
| OT premium (0.5 × RR × 4 OT hrs) | $21.09 |
| Estimated gross | $485.09 |
Worked example — nondiscretionary bonus
Forty-four hours at ten dollars an hour plus an eighty-dollar production bonus in the same workweek yields five hundred twenty dollars of straight-time pay. The regular rate is five hundred twenty divided by forty-four. The OT premium is four hours × 0.5 × the regular rate, or $23.64, so estimated gross is $520.00 + $23.64 = $543.64 before tax.
| Input or result | Example |
|---|---|
| Straight-time earnings | $520.00 |
| Regular rate | $11.8182/hr |
| OT premium (0.5 × RR × 4 OT hrs) | $23.64 |
| Estimated gross | $543.64 |
Worked example — double time
Some schedules pay double time on certain hours. At eighteen dollars an hour with thirty-eight regular hours and four hours at a two point zero multiplier, regular pay estimates to six hundred eighty-four dollars. Overtime pay estimates to four times eighteen times two, or one hundred forty-four dollars. Total estimated gross is eight hundred twenty-eight dollars before tax in this layout—enter the multiplier your policy uses when it differs.
| Input or result | Example |
|---|---|
| Regular pay | $684.00 |
| Premium pay (2.0×) | $144.00 |
| Total gross | $828.00 |
If you still need hour splits from clock times, use the overtime calculator first. Figures here are estimates for checking a pay stub, not payroll or tax advice. For the federal qualified-overtime premium deduction (IRC §225), see the no tax on overtime calculator. Round trip back to the overtime calculator when hour buckets on the stub do not match your memory of the schedule.
People also ask
- How is the regular rate calculated with two pay rates in one week?
- Under federal FLSA, add straight-time earnings from all jobs in the workweek and divide by total hours worked (weighted average per 29 CFR 778.115), unless an agreed alternative under section 7(g)(2) applies (29 CFR 778.415–778.421). Overtime then uses at least 1.5× that regular rate on hours over forty. See the regular rate section on this page.
- Do shift differentials change the overtime rate?
- Yes for federal FLSA when the differential is part of straight-time pay: include shift pay in workweek earnings before dividing by hours worked (29 CFR 778.207(b)), then apply the OT premium on hours over forty.
- How do I calculate overtime pay on my paycheck?
- Multiply regular hours by your rate and overtime hours by rate × multiplier (often 1.5). Example: $20/hr, 40 regular + 5 OT = $800 + $150 = $950.
- What is time and a half on $20 an hour?
- Overtime at 1.5× on a $20 base rate is $30 per overtime hour in this calculator.
- Do blank hours count as zero?
- Yes. Empty regular or overtime hour fields are treated as zero while you still enter your hourly rate.
- What is double time pay?
- Double time uses a 2.0× multiplier on overtime hours in this tool. Example: $20/hr with 3 double-time hours pays $120 overtime ($20 × 2 × 3) before tax in this estimate.
