How the Overtime Pay Calculator works
This calculator works out your total weekly pay by combining your normal hours at your standard rate with your overtime hours at the selected overtime multiplier. Common UK overtime rates are time-and-a-quarter (1.25×), time-and-a-half (1.5×), and double time (2×), though employers can agree any rate with workers. The effective hourly rate shows your average earnings across all hours, which is useful for understanding the true value of an overtime-heavy week.
In the UK, there is no statutory minimum premium for overtime — employers are only required to ensure the total pay divided by total hours does not drop below the applicable National Minimum Wage or National Living Wage. Overtime rates are a contractual matter. If you are paid a salary rather than an hourly wage, use the salary-to-hourly calculator first to determine your effective hourly rate before using this calculator to assess the value of overtime hours.
Frequently asked questions
How is overtime pay calculated in the UK?
Overtime pay is calculated by multiplying the number of overtime hours worked by the hourly rate and then by the overtime multiplier. For example, if your hourly rate is £15 and you work 5 hours of overtime at time-and-a-half (1.5×), your overtime pay is £15 × 1.5 × 5 = £112.50. Your total weekly pay is your normal pay plus this overtime amount. There is no single UK legal rate for overtime — it is set by your employment contract.
Is overtime pay taxed differently?
No. In the UK, overtime pay is taxed as ordinary employment income through PAYE at your normal marginal rate. There is no special tax treatment for overtime. However, a week with high overtime may push your weekly earnings above your usual level, which can temporarily affect how much tax your employer deducts via PAYE — though this self-corrects over the tax year. Overtime also counts towards your National Insurance contributions.
Does overtime count toward pension contributions?
This depends on your pension scheme rules. Under auto-enrolment, minimum contributions are calculated on 'qualifying earnings', which can include overtime depending on how your employer defines pensionable pay. Some workplace schemes base contributions only on basic salary, excluding overtime. Check your pension scheme documentation or ask your payroll department to confirm whether your overtime pay is included in your pensionable earnings.
What is the legal minimum overtime rate in the UK?
UK law does not set a minimum overtime rate or require that overtime be paid at a premium rate. Employers are only legally required to ensure that total pay, when divided by total hours worked (including overtime), does not fall below the National Living Wage or National Minimum Wage for the worker's age group. Any overtime premium above the regular rate is a matter of contractual agreement between employer and employee.
