Enter your hourly rate, the number of hours you work per week and how many weeks you work per year to instantly see your weekly, monthly and annual pay. The calculator also shows what your earnings would be if scaled up to a full-time equivalent salary based on a standard 37.5-hour week — useful for comparing part-time roles against full-time positions.

How the part-time calculator works
The calculator takes three inputs — your hourly rate, the number of hours you work per week and how many weeks per year you work — and produces a complete breakdown of your part-time earnings. Slide the hourly rate between £5 and £100, set your weekly hours from 1 to 40, and choose between 1 and 52 weeks per year (defaulting to 52 for year-round employment).
Weekly pay is simply your hourly rate multiplied by your hours per week. Annual pay multiplies that weekly figure by your weeks per year, and monthly pay divides the annual total by 12. The full-time equivalent (FTE) salary shows what you would earn at the same hourly rate working a standard 37.5-hour week for 52 weeks. Finally, the percentage of full-time tells you exactly how your hours compare to a full-time schedule.
All figures update instantly as you move the sliders or type a value. Results are shown as gross pay before tax and National Insurance deductions.
Understanding part-time work in the UK
There is no legal definition of part-time hours in the UK. In practice, any role where you work fewer hours than a comparable full-time colleague at the same employer is considered part-time. Most full-time roles are based on a 37.5-hour week (7.5 hours per day, Monday to Friday), so anything below that threshold is typically classed as part-time.
Under the Part-Time Workers (Prevention of Less Favourable Treatment) Regulations 2000, part-time employees must receive the same hourly pay rate, access to training, pension schemes and other benefits as full-time workers in comparable roles. Holiday entitlement is calculated on a pro-rata basis — if you work 3 days per week, you receive 3/5 of the full-time statutory minimum of 28 days (5.6 weeks), which equals 16.8 days per year.
Part-time workers who earn at least £10,000 per year from a single employer and are aged between 22 and State Pension age must be automatically enrolled into a workplace pension. Your employer contributes a minimum of 3% of qualifying earnings. If your annual earnings fall below the £12,570 Personal Allowance, you will not pay any Income Tax on your part-time wages.
When comparing part-time roles, the full-time equivalent salary is the most useful benchmark. It normalises different hours and rates to a common standard, so you can fairly compare a 16-hour-per-week job at £14/hour against a 24-hour role at £11/hour. This calculator handles that conversion automatically.
Frequently asked questions
What rights do part-time workers have in the UK?
Under the Part-Time Workers (Prevention of Less Favourable Treatment) Regulations 2000, part-time workers have the right to be treated no less favourably than comparable full-time colleagues. This covers pay rates, holiday entitlement, training opportunities, pension access and redundancy terms. Your employer cannot exclude you from benefits solely because you work fewer hours.
How is pro-rata holiday calculated for part-time workers?
Full-time workers in the UK receive a statutory minimum of 28 days paid leave (5.6 weeks), including bank holidays. Part-time entitlement is calculated pro rata. Multiply 5.6 by the number of days you work per week. For example, if you work 3 days per week, you are entitled to 16.8 days of paid annual leave per year.
Is there a minimum number of hours you can work part-time in the UK?
There is no legal minimum number of hours for a part-time role in the UK. You could work as few as one hour per week and still qualify for employment rights such as the National Minimum Wage, holiday pay and protection from unfair dismissal (after two years of continuous service). Your contract should specify your agreed hours.
What is the difference between part-time and zero-hours contracts?
A part-time contract specifies a set number of hours each week (or month), giving you predictable income and a regular schedule. A zero-hours contract does not guarantee any minimum hours — your employer offers work as needed and you can accept or decline. Both types of worker are entitled to the National Minimum Wage, holiday pay and protection from discrimination.
Do part-time workers qualify for auto-enrolment pension?
Yes, provided you meet the eligibility criteria. You must be aged between 22 and State Pension age and earn at least £10,000 per year from that employer. If you meet those thresholds, your employer must automatically enrol you into a workplace pension scheme and contribute a minimum of 3% of your qualifying earnings, regardless of whether you work full-time or part-time.
Do I pay tax on part-time earnings?
Yes, the same Income Tax rules apply to part-time and full-time workers. You receive a tax-free Personal Allowance of £12,570 per year. Earnings above that are taxed at 20% (basic rate) up to £50,270, then 40% (higher rate) up to £125,140 and 45% (additional rate) thereafter. If your annual part-time earnings fall below £12,570 you will not owe any Income Tax.
