How to Calculate Time-and-a-Half Pay Hours
“Time and a half” usually describes a pay rate equal to 1.5 times a base rate, but whether it applies and how it is calculated depends on the rules or agreement governing the job. First determine the eligible hours, then apply the correct rate.

Calculate the hours first
Use time records to calculate total hours worked and identify the hours that qualify under the applicable overtime rule. For example, a record might show 42 hours in a workweek, but the qualifying overtime hours depend on the rule being applied.
The ShiftHours calculator helps with durations and breaks; it does not decide which hours qualify for a premium.
Illustrative rate example
If a valid rule says a base rate of $20 per hour receives a 1.5 multiplier for a particular hour, the illustrative rate would be $30 for that hour. The correct base rate and eligible hours must be established first.
This is an arithmetic example, not a statement that a specific worker is legally entitled to this rate.
Keep regular and premium hours separate
A clear payroll record shows regular hours, any qualifying premium hours, the applicable rate, and the source of the rule. Do not assume all hours beyond a daily scheduled shift receive the same treatment.
Rules vary by location, role, contract, and other factors. Check an authoritative local source or qualified payroll professional for an actual pay calculation.
Verify your time total
Use the work hours calculator to check shift lengths and unpaid breaks before applying any payroll formula.
Use the free ShiftHours work hours calculator to calculate shift length, subtract unpaid breaks, and view decimal hours. For weekly totals, try the weekly calculator.
Example: calculating time-and-a-half pay
If a worker’s regular hourly rate is $16, a time-and-a-half rate is $16 × 1.5 = $24 per hour. For 2 eligible overtime hours, the premium-rate amount would be $48 before any other payroll adjustments. Eligibility and overtime rules depend on the applicable law and employment arrangement; this example is arithmetic only.
