If You Worked Different Overtime
The premium is $10.00 an hour — half the regular rate — so the overtime hours add $80.00 more than they would at straight time.
Overtime is 23.1% of the total pay from 16.7% of the hours, which is the effect of the 1.5× rate.
Time and a half applies to the regular rate of pay, which under federal rules includes most non-discretionary bonuses and shift differentials — not just the base hourly wage. A production bonus can therefore raise the overtime rate above 1.5× the base figure.
All amounts are gross, before tax and deductions. Overtime pay is taxed as ordinary income, and because withholding tables assume each paycheck is typical, a heavy overtime week can over-withhold and be reconciled at filing.
Step-by-Step Calculation
Weekly pay period
Step 1 — Overtime hourly rate
Overtime Rate = Regular Rate × 1.5
Overtime Rate = $20.00 × 1.5 = $30.00
Step 2 — Regular pay
Regular Pay = 40 h × $20.00 = $800.00
Step 3 — Overtime pay
Overtime Pay = 8 h × $30.00 = $240.00
Step 4 — Total pay
Total = $800.00 + $240.00 = $1,040.00
Result
$1,040.00 for 48 hours — a blended $21.67 an hour
What Time and a Half Means
Time and a half is 1.5 times your regular hourly rate. At $20 an hour it is $30 — the base $20 plus a $10 premium, which is exactly half the regular rate.
Splitting it that way is useful, because the premium is the part that actually costs the employer extra. Eight overtime hours at a $20 base are $160 of straight time plus $80 of premium, and payroll systems commonly report those two components separately on a payslip.
The other figure worth knowing is the blended rate — total pay divided by total hours. On the Example 1 week that is $21.67, not $20 and not $30, and it is the number that tells you what your time was really worth.

What Each Overtime Hour Adds
At $20 an hour on top of 40 regular hours:
| OT Hours | Overtime Pay | Total Pay | Blended Rate | OT % of Pay |
|---|---|---|---|---|
| 0 | $0.00 | $800.00 | $20.00 | 0.0% |
| 2 | $60.00 | $860.00 | $20.48 | 7.0% |
| 4 | $120.00 | $920.00 | $20.91 | 13.0% |
| 8 | $240.00 | $1,040.00 | $21.67 | 23.1% |
| 12 | $360.00 | $1,160.00 | $22.31 | 31.0% |
| 16 | $480.00 | $1,280.00 | $22.86 | 37.5% |
| 20 | $600.00 | $1,400.00 | $23.33 | 42.9% |
Overtime consistently claims a larger share of the pay than of the hours — at 8 hours it is 16.7% of the hours but 23.1% of the pay. The blended rate climbs toward $30 but never reaches it, because the 40 regular hours keep pulling it down.
The Premium Is Half the Rate
It helps to see overtime pay as two parts. The hours would have been paid at straight time anyway; the premium is what time and a half adds on top:
| Component | Rate | 8 Hours |
|---|---|---|
| Straight time | $20.00 | $160.00 |
| Premium (half rate) | $10.00 | $80.00 |
| Overtime pay | $30.00 | $240.00 |
On Example 2's $18.50 wage the premium is $9.25 an hour, so 5 overtime hours earn $46.25 more than straight time would have paid.
Time and a Half Against Other Premiums
Eight hours at a $20 base, under each premium rate you are likely to encounter:
| Premium | Multiplier | Rate | 8 Hours Pay |
|---|---|---|---|
| Straight time | 1.00× | $20.00 | $160.00 |
| Time and a quarter | 1.25× | $25.00 | $200.00 |
| Time and a third | 1.33× | $26.67 | $213.33 |
| Time and a half | 1.50× | $30.00 | $240.00 |
| Double time | 2.00× | $40.00 | $320.00 |
| Double time and a half | 2.50× | $50.00 | $400.00 |
Only time and a half above 40 weekly hours is a federal requirement. Double time comes from state law — California applies it beyond 12 hours in a day — or from a contract, and holiday premiums are almost always contractual rather than legally mandated.
Why the Overtime Rate Sometimes Shows Three Decimals
Multiplying a two-decimal wage by 1.5 can land on a third decimal — a half-cent. At $7.17 an hour the overtime rate is exactly $10.755, which no payroll system can pay but every payroll system must calculate from.
Rounding that rate to $10.76 before multiplying introduces real error:
| Wage | Exact OT Rate | Hours | Correct Pay | If Rate Rounded |
|---|---|---|---|---|
| $7.17 | $10.755 | 30.29 | $325.77 | $325.92 |
| $18.33 | $27.495 | 8 | $219.96 | $220.00 |
| $15.55 | $23.325 | 5 | $116.63 | $116.65 |
| $13.37 | $20.055 | 10 | $200.55 | $200.60 |
Small amounts, but they accumulate across a workforce and a year, and they are the kind of discrepancy a payroll audit looks for. This calculator computes from the exact rate and displays enough precision for the step-by-step line to multiply out correctly.
When Overtime Is Actually Owed
The federal Fair Labor Standards Act requires at least 1.5× for hours over 40 in a workweek for non-exempt employees. That is a weekly test, not a daily one — a 12-hour day followed by three short days may produce no federal overtime at all.
Other triggers exist on top of it. California requires time and a half above 8 hours in a day and double time above 12. Several states have their own daily rules, and union agreements often add premiums for seventh consecutive days or scheduled days off.
That is why this calculator takes your hours as entered rather than splitting at 40. Example 3 shows what happens when the two diverge: 35 regular plus 10 overtime is a 45-hour week, which the federal weekly rule alone would pay as 40 + 5:
| Split of a 45-Hour Week | Regular Pay | Overtime Pay | Total |
|---|---|---|---|
| 35 + 10 (as entered) | $875.00 | $375.00 | $1,250.00 |
| 40 + 5 (federal weekly rule) | $1,000.00 | $187.50 | $1,187.50 |
A $62.50 difference on the same 45 hours. The calculator flags the mismatch and shows both, because the entered split is correct if a daily or contractual rule applies — and a mistake if it does not.
Benefits of Using the Time and a Half Calculator
Example Calculations
Three pay periods worked through step by step:
Example Scenario 1 — $20 an Hour
40 regular hours plus 8 overtime hours.
Overtime Rate = $20 × 1.5 = $30.00
Regular Pay = 40 h × $20 = $800.00
Overtime Pay = 8 h × $30 = $240.00
Total Pay = $800 + $240 = $1,040.00
The 8 overtime hours are 16.7% of the hours but 23.1% of the pay
Blended rate across all 48 hours: $21.67
Example Scenario 2 — $18.50 an Hour
40 regular hours plus 5 overtime hours.
Overtime Rate = $18.50 × 1.5 = $27.75
Regular Pay = 40 h × $18.50 = $740.00
Overtime Pay = 5 h × $27.75 = $138.75
Total Pay = $740 + $138.75 = $878.75
The premium is $9.25 an hour — half the base rate
Those 5 hours earn $46.25 more than straight time would
Example Scenario 3 — $25 an Hour, 45-Hour Week
35 regular hours plus 10 overtime hours.
Overtime Rate = $25 × 1.5 = $37.50
Regular Pay = 35 h × $25 = $875.00
Overtime Pay = 10 h × $37.50 = $375.00
Total Pay = $875 + $375 = $1,250.00
Note: 45 hours under the federal weekly rule alone would be 40 + 5
That split gives $1,187.50 — $62.50 less, so the extra premium must come from a daily or contractual rule
What This Does Not Decide for You
Whether overtime is owed at all, and on which hours, is a legal question this calculator does not answer — it prices the hours you classify. Exempt employees, typically salaried executive, administrative and professional staff meeting both a salary threshold and a duties test, are not entitled to federal overtime regardless of hours worked, and job title alone does not establish exemption. Federal rules also apply the 1.5× to the "regular rate of pay" rather than the base wage, which must include most non-discretionary bonuses, shift differentials and commissions — so a production bonus genuinely raises the overtime rate above 1.5× the base figure, and leaving it out understates what is owed. State law frequently adds daily thresholds, seventh-day rules and double-time triggers on top of the federal weekly test, and union agreements can add more. Figures here are gross, before tax and deductions; overtime is taxed as ordinary income, though withholding tables assume every paycheck is typical, so a heavy overtime week can over-withhold and be reconciled at filing. For anything contested, check your state labour department and the federal Wage and Hour Division. This is general information, not legal or payroll advice.
Frequently Asked Questions
- What does time and a half mean?
- Being paid 1.5 times your regular hourly rate for qualifying hours. At $20 an hour, time and a half is $30 an hour — the base $20 plus a $10 premium, which is half the regular rate.
- How do you calculate time and a half?
- Multiply the hourly rate by 1.5, then multiply by the overtime hours. At $20 an hour with 8 overtime hours, that is $30 × 8 = $240. Add the regular pay of 40 × $20 = $800 for a total of $1,040.
- When is overtime legally required?
- Under the federal Fair Labor Standards Act, non-exempt employees must be paid at least 1.5× for hours over 40 in a workweek. Some states go further — California requires it above 8 hours in a day and double time above 12 — and union agreements often add their own triggers.
- Why does this calculator not split my hours at 40 automatically?
- Because overtime triggers vary. The federal rule is weekly, but daily thresholds, seventh-consecutive-day rules and contractual premiums all exist, so the hours you enter are respected. If a weekly total above 40 does not match the federal split, the calculator flags it and shows what that split would pay.
- What is the premium portion of overtime pay?
- Half the regular rate — the part above straight time. At $20 an hour the premium is $10, so 8 overtime hours cost $160 in straight time plus $80 of premium, totalling $240. Payroll systems often report the premium separately.
- Why is the overtime rate shown with three decimal places sometimes?
- Because multiplying a two-decimal wage by 1.5 can produce a third decimal. At $7.17 an hour the overtime rate is exactly $10.755. Showing it as $10.76 and multiplying would give $325.92 on 30.29 hours instead of the correct $325.77, so the exact rate is used and displayed.
- Is overtime based on my base wage only?
- No. Federal rules apply the 1.5× to your "regular rate of pay", which includes most non-discretionary bonuses, shift differentials and commissions — not just the base hourly wage. A production bonus can therefore push your true overtime rate above 1.5× the base figure.
- Does everyone qualify for overtime?
- No. Exempt employees — typically salaried executive, administrative and professional staff meeting both a salary threshold and a duties test — are not entitled to overtime under federal law. Job title alone does not determine exemption; the actual duties and pay basis do.
- Is overtime taxed at a higher rate?
- No, it is taxed as ordinary income like the rest of your pay. It can feel higher because withholding tables assume every paycheck is typical, so a heavy overtime week can over-withhold — which is reconciled when you file.
- What is the difference between time and a half and double time?
- The multiplier. Time and a half is 1.5×, double time is 2×. On 8 hours at a $20 base, time and a half pays $240 and double time pays $320. Double time is not a federal requirement — it comes from state rules like California's or from a contract.
