In-Depth Guide to the 4 on 4 Off Shift Pattern Pay Calculator
What is a 4 on 4 off Shift Pattern?
A “4 on 4 off” shift pattern is a work schedule where an employee works for four consecutive days, followed by four consecutive days of rest. This cycle repeats every eight days. It is commonly used in industries that require 24/7 coverage, such as manufacturing, logistics, security, and emergency services. The primary benefit is the extended period of time off, which provides employees with a mini-break after each work block. This regular, predictable schedule is a key reason many prefer it. Understanding your income on this schedule can be complex, which is why a dedicated 4 on 4 off shift pattern pay calculator is an invaluable tool.
This schedule averages 3.5 shifts per week over the year, meaning an employee works half the year (approximately 182.5 days). For those working 12-hour shifts, this equates to an average of 42 hours per week, often including built-in overtime depending on the contract. The rotating nature means the days you work change each week, cycling through weekdays and weekends.
4 on 4 off shift pattern pay calculator: Formula and Mathematical Explanation
Calculating your pay on a 4 on 4 off rota requires breaking it down into an 8-day cycle. Our 4 on 4 off shift pattern pay calculator automates this, but here is the manual calculation process.
- Calculate Paid Hours per Shift: Subtract any unpaid break time from the total shift duration.
Formula: Paid Hours = Shift Hours – (Unpaid Break Minutes / 60) - Calculate Base Pay per Cycle: Multiply the paid hours per shift by your hourly rate, then by 4 (the number of workdays in a cycle).
Formula: Base Pay per Cycle = Paid Hours × Hourly Rate × 4 - Calculate Overtime Pay per Cycle: Multiply any overtime hours worked within the 8-day cycle by your overtime rate.
Formula: Overtime Pay = Overtime Hours × Hourly Rate × Overtime Rate Multiplier - Calculate Total Pay per Cycle: Add the base pay and overtime pay together.
Formula: Total Pay per Cycle = Base Pay per Cycle + Overtime Pay per Cycle - Calculate Annual Salary: Since a year has 365.25 days on average, there are approximately 45.656 cycles per year (365.25 / 8). Multiply your total pay per cycle by this number.
Formula: Annual Salary = Total Pay per Cycle × (365.25 / 8)
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Hourly Rate | Amount earned per hour of work. | Currency (£, $, €) | 10 – 30 |
| Shift Hours | Total length of a single shift. | Hours | 8 – 12 |
| Unpaid Break | Break time not paid for. | Minutes | 0 – 90 |
| Overtime Hours | Extra hours worked per 8-day cycle. | Hours | 0 – 16 |
Practical Examples (Real-World Use Cases)
Example 1: Security Officer on a Standard Rota
A security officer works a 4 on 4 off pattern with 12-hour shifts. Their breaks are unpaid.
- Inputs:
- Hourly Rate: £14.50
- Hours per Shift: 12
- Unpaid Break: 60 minutes
- Overtime Hours: 0
- Calculation:
- Paid hours per shift = 12 – (60 / 60) = 11 hours
- Pay per cycle = 11 hours × 4 days × £14.50 = £638
- Annual Salary = £638 × (365.25 / 8) = £29,114.93
- Interpretation: The officer can expect an annual gross salary of around £29,115, assuming no overtime is worked. Using a reliable 4 on 4 off shift pattern pay calculator helps confirm these earnings.
Example 2: Manufacturing Technician with Overtime
A technician works the same pattern but frequently does extra hours to cover maintenance tasks.
- Inputs:
- Hourly Rate: £18.00
- Hours per Shift: 12
- Unpaid Break: 30 minutes
- Overtime Hours (per cycle): 8
- Overtime Rate: 1.5x
- Calculation:
- Paid hours per shift = 12 – (30 / 60) = 11.5 hours
- Base pay per cycle = 11.5 hours × 4 days × £18.00 = £828
- Overtime pay per cycle = 8 hours × £18.00 × 1.5 = £216
- Total pay per cycle = £828 + £216 = £1,044
- Annual Salary = £1,044 × (365.25 / 8) = £47,624.55
- Interpretation: The technician’s frequent overtime significantly boosts their annual earnings to over £47,000. It’s crucial to use a precise salary to hourly converter to see how this compares to a standard salary.

Key Factors That Affect 4 on 4 off Shift Pattern Pay
Several factors can influence your final earnings. Understanding them is key to accurately forecasting your income with the 4 on 4 off shift pattern pay calculator.
- Hourly Rate: The foundation of your earnings. A small increase can have a large impact on your annual salary.
- Shift Length: 12-hour shifts are common and lead to higher earnings per cycle compared to 8 or 10-hour shifts on the same pattern.
- Unpaid Breaks: A 60-minute unpaid break on a 12-hour shift reduces your paid time by over 8%. If possible, negotiating for paid breaks significantly increases income.
- Overtime Availability: The opportunity to work extra hours at a premium rate is the single biggest factor for boosting earnings beyond the basic salary. Explore our overtime calculator for more details.
- Night/Weekend Premiums: Some employers offer shift differentials (extra pay) for unsociable hours. Our calculator focuses on base and overtime pay, but these premiums can add another layer to your income.
- Bonuses and Holiday Pay: Contractual bonuses or special rates for working public holidays are not included in this standard calculation but are an important part of your total compensation.
Frequently Asked Questions (FAQ)
How many hours a week is a 4 on 4 off shift?
For 12-hour shifts, a 4 on 4 off pattern averages 42 hours per week over the course of a year (182.5 working days × 12 hours / 52.1775 weeks).
Is the 4 on 4 off shift pattern good for work-life balance?
Many people find the four consecutive days off highly beneficial for rest, hobbies, and family time, even though the four workdays can be long and demanding.
Why use a specific 4 on 4 off shift pattern pay calculator?
Because the pay cycle is 8 days, not a standard week or month, a specialized calculator is needed to correctly convert the cyclical pay into familiar annual, monthly, and weekly equivalents.
Does this calculator account for taxes?
No, this calculator shows your gross pay (before taxes and other deductions). To estimate your take-home pay, you should consult a take-home pay calculator after determining your gross earnings here.
How many days do you work a year on a 4 on 4 off rota?
You work for half of the year. On an average year (365.25 days), you will work approximately 182 to 183 days.
How do I handle rotating day and night shifts?
If your pay rate is the same for both, the calculation remains unchanged. If you receive a shift differential (extra pay) for nights, you would need to calculate that portion separately and add it to the total. Our calculator is a great starting point for the base calculation.
What if my shifts are not 12 hours long?
This 4 on 4 off shift pattern pay calculator is fully flexible. Simply change the “Hours per Shift” input to 8 or 10, and all calculations will adjust accordingly.
How are weekends affected by this shift pattern?
The schedule is continuously rotating, so you will inevitably work weekends. The pattern ensures that weekend work is distributed fairly among all teams on the same rota over time.
