How to use this calculator
The overtime pay calculator separates one workweek’s hours into regular and overtime portions, then estimates gross earnings. Enter total hours, one hourly rate, the threshold at which the premium begins, and the multiplier. The initial 40-hour threshold and 1.5 multiplier are editable assumptions, not a determination that they apply to every worker or location.
Use this page when the hours already belong to one defined workweek. A two-week pay period may contain two different overtime calculations, so do not combine both weeks and apply one threshold. The tool does not determine eligibility, handle daily overtime, calculate a weighted regular rate, or include taxes, deductions, bonuses, and other adjustments.
Formula and calculation method
Regular hours = min(total hours, threshold). Overtime hours = max(total hours − threshold, 0). Gross = regular hours × rate + overtime hours × rate × multiplier.
Split the hours once
Hours up to the threshold are counted in the regular portion. Hours beyond it are counted only in the overtime portion. The premium rate already includes the base rate when you use a multiplier such as 1.5, so adding a second full base payment for those same hours would overstate gross pay.
Use an appropriate rate and workweek
The entered rate is used for every hour in this simplified model. If compensation includes multiple rates or other items affecting the regular rate, determine the appropriate calculation separately. The linked Department of Labor reference explains the U.S. federal workweek framework; local or other applicable rules may require a different model.
Worked examples
Five hours at time and a half
Enter 45 hours, rate 20, threshold 40, and multiplier 1.5. Regular pay is 40 × 20 = 800. Overtime pay is 5 × 20 × 1.5 = 150. Total gross is 950. The five overtime hours are paid at 30 each, including their base compensation.
A week below the threshold
Enter 35 hours at 24 with a threshold of 40. All 35 hours fall in the regular portion, producing 840 gross and zero overtime pay. The multiplier has no effect until hours exceed the selected threshold. This helps verify the boundary before testing a longer workweek.
Use a different premium assumption
For a scenario with 42 hours at 25, threshold 40, and multiplier 2, the regular portion is 1,000 and the two premium hours contribute 100. Gross is 1,100. This models one premium tier; it does not simultaneously apply time-and-a-half and double-time thresholds.
Edge cases and practical checks
Do not average different workweeks
A 45-hour week followed by a 35-hour week is not the same scenario as two 40-hour weeks. Calculate each week independently under the applicable rules, then add the gross amounts. A paycheck covering several weeks does not by itself make those hours a single overtime period.
Excluded complexities
The page supports one rate, one threshold, and one multiplier per workweek. It does not determine which leave hours count, calculate daily premiums, or include bonuses in a regular-rate calculation. Enter hours on a consistent basis and use a more complete payroll process when those additional rules are relevant.
Frequently asked questions
What does time and a half mean?
It means a rate equal to 1.5 times the base rate used in the calculation. At 20 per hour, that is 30 per overtime hour. The 30 includes the ordinary 20 plus a 10 premium, so do not add another full base payment to it.
Does overtime start at 40 hours for everyone?
No universal rule is determined here. Forty is the editable starting assumption for this calculator. Eligibility, workweek rules, daily thresholds, and other requirements depend on the applicable framework and the worker’s circumstances. Use inputs appropriate to the specific scenario.
Can I enter a two-week total?
Calculate each defined workweek separately when applying a weekly threshold. Combining hours from different weeks can hide a premium in one week behind fewer hours in another. Add the resulting weekly gross amounts afterward if you need a pay-period estimate.
Are taxes included?
No. The result is gross arithmetic pay before deductions. A paycheck deposit can differ because of withholding, benefits, other deductions, reimbursements, or adjustments. This page does not collect the information needed to estimate those amounts.
Can I calculate double time?
Set the multiplier to 2 for a scenario with one double-time tier above the threshold. The calculator does not combine multiple premium tiers in one result. If your rules include both daily and weekly premiums, avoid double-counting the same hours.
Can paid leave count toward the threshold?
That depends on the rule you are applying. This tool does not distinguish worked hours from paid leave, so you must enter an appropriate total. Keep the source categories separate until you know which hours belong in the overtime calculation.
