Free Online Overtime Calculator
Calculate regular pay, overtime pay, and total earnings.
Double-time hours are paid at twice the base rate and are reported separately from the overtime multiplier. Overtime rules vary by country, industry, and employment contract, so confirm the applicable multiplier and thresholds with your payroll provider.
About the Overtime Calculator
Overtime pay is the premium an employer pays for hours worked beyond a standard threshold. In many places the threshold is forty hours in a workweek, and the premium is one and a half times the normal rate, but both details can vary by jurisdiction, union agreement, or contract. This calculator takes the hourly rate, the number of regular hours, the number of overtime hours, and the overtime multiplier, then reports regular pay, overtime pay, and total pay. An optional double-time field covers the higher rate that some agreements apply to weekends, public holidays, or very long shifts.
The three pay components
Regular pay is the base hourly rate multiplied by the regular hours. Overtime pay is the base rate multiplied by the overtime multiplier and then by the overtime hours. Double-time pay uses a fixed factor of two. The total is the sum of all three components. The blended rate divides total pay by all paid hours, which gives a useful average for budgeting and for comparing offers that use different shift patterns. It is not the same as the marginal overtime rate, because regular hours dilute the premium.
Choosing the multiplier
The common time-and-a-half multiplier is 1.5, but the field accepts values from 1 to 5 so you can model double time, triple time, or a contractual premium. If overtime hours are already included in the regular hours figure, do not enter them twice. For example, if someone worked 46 hours in a week with a 40-hour threshold, enter 40 regular hours and 6 overtime hours. If the threshold is different, adjust the regular hours to match the number of hours paid at the base rate.
What is not included
The result is gross pay before income tax, social security, pension contributions, and other deductions. It also excludes shift differentials, tips, bonuses, commissions, and paid leave, which may be calculated separately. Some employers average hours over two weeks or use a daily overtime rule, and some salaried staff are exempt from overtime altogether. Use the calculator as a transparent estimate and check the final figure against the rules that apply to the employment relationship.
Frequently asked questions
Does overtime pay apply to all hours above eight in a day?
Not everywhere. Some jurisdictions use a daily threshold, some use a weekly one, and some use both. This calculator uses the hours you enter rather than assuming a rule.
Why is the blended rate lower than the overtime rate?
Because most hours are paid at the base rate. The blended rate averages the premium across all hours worked.
Can I use decimals for partial hours?
Yes. Quarter-hour values such as 37.75 or 1.25 are accepted, which matches common timekeeping increments.
