Overtime Calculator

Time and a half on a $20 base hourly rate is $30 per overtime hour, and 40 regular plus 5 overtime hours produces $950 gross under this simple split. Enter base rate, regular hours, overtime hours, and multiplier to calculate regular pay, overtime pay, total hours, and total gross pay. The calculator does not decide which hours legally qualify. It trusts the hours and multiplier you enter. Overtime thresholds can depend on jurisdiction, workweek definition, daily hours, occupation, exemption status, union agreement, public-sector rules, prevailing wage, multiple rates, bonuses, commissions, shift differentials, and employer policy. The output is gross arithmetic before withholding, deductions, or payroll-specific rounding.

Quick answer

Overtime rate is your regular hourly wage multiplied by the overtime rate, usually 1.5 for time and a half.

What this tells you

  • Overtime rate is your regular hourly wage multiplied by the overtime rate, usually 1.5 for time and a half.
  • Overtime pay applies only to the overtime hours, not to your whole paycheck.
  • A common US federal rule covers eligible non-exempt hours over 40 in a defined workweek, but other rules and exceptions may apply.
  • The tool does not automatically move hours above a threshold into the overtime field.
  • Money and total hours display to 2 decimals after calculations use the entered values.
  • The regular rate used by law may include more than a stated base hourly wage.

How to Use

  1. 1Enter your regular hourly wage in dollars.
  2. 2Enter the regular hours you worked in the pay period, often 40 for a week.
  3. 3Enter your overtime hours.
  4. 4Set the overtime multiplier. Use 1.5 for time and a half or 2 for double time.
  5. 5Calculate to see your overtime rate, overtime pay, and total gross pay.
  6. 6Confirm which hours qualify under the governing law, agreement, and defined workweek.
  7. 7Check whether bonuses, commissions, shift premiums, or multiple job rates change the regular rate.
  8. 8Compare the estimate with payroll records and raise discrepancies promptly through an appropriate channel.

How It Works

Formula

Overtime rate = regular hourly rate x overtime multiplier Overtime pay = overtime rate x overtime hours Total pay = (regular rate x regular hours) + overtime pay Example: $20 x 1.5 = $30/hr, then (40 x $20) + (5 x $30) = $950

The multiplier applies only to the overtime hours. Your regular hours are still paid at the base rate, and the two amounts are added together. Time and a half means a multiplier of 1.5, so the overtime hours pay 50% more than the base wage.

Calculation note: values are processed in the order shown above, using the current input units.

Worked Examples

Time and a half for $20 an hour

Hourly wage$20
Regular hours40
Overtime hours5
Multiplier1.5
ResultOvertime rate $30/hr, total pay $950

Regular pay is 40 x $20 = $800. Overtime pay is 5 x $30 = $150. Together that is $950 gross for the week.

Double time on a holiday shift

Hourly wage$25
Regular hours40
Overtime hours4
Multiplier2
ResultOvertime rate $50/hr, total pay $1,200

Double time pays twice the base rate. The 4 holiday hours add $200 on top of the $1,000 regular pay.

Fractional overtime hours

Hourly wage$15
Regular hours40
Overtime hours2.5
Multiplier1.5
ResultOvertime rate $22.50/hr, total pay $656.25

Regular pay is $600. Overtime pay is 2.5 x $22.50 = $56.25, producing $656.25 gross across 42.5 entered hours.

No overtime hours entered

Hourly wage$18
Regular hours40
Overtime hours0
Multiplier1.5
ResultOvertime pay $0, total pay $720

The displayed overtime rate is still $27, but multiplying it by zero overtime hours gives no overtime pay. Regular pay is 40 x $18 = $720.

Time-and-a-Half and Double-Time Rates by Wage

The overtime rate for common hourly wages at the two most used multipliers: 1.5 for time and a half and 2 for double time.

Hourly wageTime and a half (1.5x)Double time (2x)
$10$15.00$20.00
$12$18.00$24.00
$15$22.50$30.00
$16$24.00$32.00
$18$27.00$36.00
$20$30.00$40.00
$22$33.00$44.00
$25$37.50$50.00
$30$45.00$60.00
$35$52.50$70.00
$40$60.00$80.00

Time and a half = wage x 1.5. Double time = wage x 2. These are the hourly overtime rates, before taxes. Use the calculator above for total pay across regular and overtime hours.

Entered hours versus legal overtime

The formula separates hours into two buckets supplied by the user. It multiplies regular hours by base rate and overtime hours by base rate times multiplier. It does not inspect a calendar, timesheet, threshold, meal period, consecutive day, or workweek boundary.

In payroll law, regular rate can differ from base wage. Certain nondiscretionary bonuses, commissions, shift differentials, piece rates, and multiple-rate work may affect the rate used for overtime. This calculator cannot perform that allocation.

Eligibility is also separate from arithmetic. Exemption tests, occupation rules, salary arrangements, collective bargaining, public employment, jurisdiction, and contract terms may alter whether overtime is due and at what multiplier. Holiday double time is not automatically created by entering holiday hours.

Gross overtime can lead to higher withholding on a larger paycheck, but withholding is not the final tax calculation. The calculator excludes income tax, payroll tax, benefits, garnishments, retirement contributions, leave, and employer payroll rounding.

Estimate Take-Home Pay

Common mistakes

  • Applying the multiplier to all hours instead of only the overtime hours
  • Using net or take-home pay instead of your gross hourly wage
  • Assuming every hour over 8 in a day counts as overtime, which is a state rule, not a federal one
  • Expecting the calculator to identify eligible overtime hours or the governing threshold
  • Using base wage when bonuses, commissions, or different rates must be included in regular rate
  • Combining hours across different legal workweeks before applying a weekly threshold
  • Reading gross pay as take-home pay or assuming withholding equals final tax

Limitations

This estimate uses one positive base hourly rate, one positive multiplier, and user-separated regular and overtime hours. It does not determine eligibility, exemption, workweek boundaries, daily or weekly thresholds, seventh-day rules, holiday terms, comp time, on-call time, travel, training, breaks, multiple rates, piecework, tips, commissions, bonuses, shift differentials, salary conversion, or fluctuating-workweek methods. It does not calculate taxes, withholding, benefits, deductions, leave, garnishments, or payroll-system rounding. Laws and contracts vary and can change.

Frequently Asked Questions

Time and a half for $20 an hour is $30 an hour. That is $20 multiplied by 1.5. Five overtime hours at that rate add $150 to your pay, so a 45-hour week at a $20 base wage is $950 gross.
Multiply your hourly wage by the overtime rate, usually 1.5, to get your overtime rate. Then multiply that by your overtime hours. Add the result to your regular pay. For example, $18 an hour with 6 overtime hours is $27 x 6 = $162 in overtime pay on top of your base.
Under the federal Fair Labor Standards Act, non-exempt employees earn overtime for hours worked over 40 in a single workweek. Some states, such as California, also require overtime after 8 hours in a day, so check your state rules.
Double time pays twice your regular hourly rate, a multiplier of 2. It is not required by federal law. It usually comes from state rules, union contracts, or company policy for holidays or very long shifts. Set the multiplier to 2 to calculate it here.
No. Overtime pay is taxed the same way as regular pay. A larger paycheck can push more of your income into a higher withholding bracket for that period, which can make it look like overtime is taxed more, but your overall tax rate does not change just because the hours were overtime.
Time and a half for $15 an hour is $22.50, and for $25 an hour it is $37.50. The rule is the same for any wage: multiply the hourly rate by 1.5 to get the overtime rate.
No. Enter regular and overtime hours separately after determining which hours qualify under the applicable workweek rule, law, policy, or agreement.
They can. Certain nondiscretionary bonuses and other compensation may need to be included in the legal regular rate. A payroll professional or qualified adviser can evaluate the specific payment.
No. It is gross pay before taxes, withholding, benefits, retirement contributions, garnishments, and other deductions.
