What Is Weekly Pay?
Weekly pay is the gross amount you earn for work completed during a single week. It is calculated by multiplying your hourly rate by the number of hours worked in that week. If you work overtime, your weekly gross pay increases accordingly. This weekly pay calculator UK helps you understand your weekly earnings and how they relate to monthly and annual income.
How the Weekly Pay Calculator Works
This weekly wage calculator is designed for simplicity. Enter your hourly rate, regular hours and any overtime hours with the appropriate overtime multiplier. The calculator then shows your total weekly pay, broken down into regular and overtime components, along with estimated monthly and annual equivalents. It's ideal for employees, freelancers and anyone paid on an hourly basis.
How to Calculate Weekly Pay From an Hourly Rate
To calculate weekly pay from an hourly rate, multiply your hourly rate by your regular hours worked.
For example, if you earn £15 per hour and work 37.5 hours, your weekly salary is £15 × 37.5 = £562.50 (gross).
Weekly Pay Formula
Overtime Pay = Hourly Rate × Overtime Hours × Overtime Multiplier
Total Weekly Pay = Regular Pay + Overtime Pay
How Overtime Changes Weekly Pay
Overtime pay is calculated at a higher rate than regular pay. The overtime multiplier is typically 1.5 (time-and-a-half) or 2.0 (double-time) in the UK. For example, at £15/hour with 5 hours overtime at 1.5x: overtime pay = £15 × 5 × 1.5 = £112.50. Your total weekly pay becomes £562.50 + £112.50 = £675.00.
Weekly Pay Examples
Example 1: £12/hour, 37.5 hours → £450/week
Example 2: £15/hour, 37.5 hours → £562.50/week
Example 3: £18/hour, 40 hours → £720/week
Example 4: £20/hour, 37.5 hours + 5 hours overtime (1.5x) → £750 + £150 = £900/week
Example 5 (part-time): £14/hour, 25 hours → £350/week
Weekly Pay Table
The table below shows weekly pay for common hourly rates and hours, assuming no overtime.
| Hourly Rate | 20 hrs/week | 30 hrs/week | 37.5 hrs/week | 40 hrs/week |
|---|---|---|---|---|
| £10.00 | £200 | £300 | £375 | £400 |
| £12.00 | £240 | £360 | £450 | £480 |
| £15.00 | £300 | £450 | £562.50 | £600 |
| £18.00 | £360 | £540 | £675 | £720 |
| £20.00 | £400 | £600 | £750 | £800 |
| £25.00 | £500 | £750 | £937.50 | £1,000 |
Weekly Pay vs Annual Salary
Your annual salary is your weekly pay multiplied by the number of paid weeks you work per year. This weekly earnings calculator shows the annualised figure based on the weeks you enter. For example, £562.50/week × 52 weeks = £29,250 per year.
How to Convert Weekly Pay to Monthly Income
A common mistake is multiplying weekly pay by 4 to get monthly income. Since there are 52 weeks in a year and 12 months, the correct monthly equivalent is: weekly pay × 52 ÷ 12. For example, £562.50 × 52 ÷ 12 = £2,437.50 per month. This weekly pay calculator does this conversion for you.
How Weekly Pay Relates to Hourly Wages
Weekly pay is directly derived from your hourly wage. The more hours you work, the higher your weekly earnings. This relationship is the foundation of this weekly salary calculator — it's designed to help you see the full picture of your weekly gross pay.
Gross Weekly Pay vs Take-Home Pay
The results from this weekly wage calculator UK show gross weekly pay — before deductions. Your actual take-home pay will be lower after Income Tax, National Insurance and other deductions. For a complete picture, consider using a Salary Calculator UK or a dedicated Take Home Pay Calculator when available.
Note: Overtime pay is also subject to tax and National Insurance. This calculator shows gross pay only.
Regular Hours vs Overtime Hours
Regular hours are your standard contracted hours. Overtime hours are any additional hours worked beyond your regular schedule, usually paid at a higher rate. This weekly paycheck calculator distinguishes between the two to give you an accurate weekly gross pay figure.
Weekly Pay for Full-Time and Part-Time Workers
This weekly income calculator works for all work patterns. Whether you're full-time (typically 35–40 hours/week) or part-time, simply enter your actual hours. The calculator adapts to show your weekly wages based on your specific working pattern.
What Happens When You Work Fewer Than 52 Weeks?
The annualised equivalent shown in this calculator is based on the weeks per year you enter. If you work fewer than 52 paid weeks (e.g., seasonal work, unpaid leave), your annualised figure will be lower. Use the weeks input to model different scenarios.
Common Weekly Pay Calculation Mistakes
- Incorrect hours — always use your actual contracted hours.
- Confusing gross and net pay — this calculator shows gross pay before deductions.
- Forgetting overtime — include any additional hours worked.
- Using the wrong multiplier — check your overtime rate.
- Assuming 4 weeks = 1 month — use the correct monthly conversion.
- Incorrect annualisation — use the correct number of paid weeks.
