Clock-in rounding rules determine how an employer treats the minutes between an employee’s actual clock-in time and the nearest rounding increment — and rounding must be fair and neutral to be legal.
When an employee clocks in at 8:57 AM and their shift starts at 9:00 AM, what time gets recorded? When they clock out at 5:03 PM, is that recorded as 5:00 PM or 5:05 PM? Rounding rules answer these questions. But rounding must not systematically underpay employees — and the rules differ by jurisdiction.
This article explains rounding rules, what is legal in the UK, US, and Australia, and how to configure rounding correctly.
Key Takeaways
- Rounding must be neutral — it cannot systematically favour the employer
- The most common rounding increment is 5 minutes (nearest 5-minute mark)
- In the US, the 7-minute rule is widely used but must be applied both ways
- In the UK, rounding should not reduce hours below the Working Time Regulations threshold
- In Australia, Modern Award rules may specify how rounding is applied
- Configuring rounding incorrectly creates underpayment risk
What Is Clock-In Rounding?
Rounding is the practice of adjusting an employee’s recorded clock-in or clock-out time to the nearest configured increment. Common increments:
| Increment | Example | 8:57 AM rounds to | 5:03 PM rounds to |
|---|---|---|---|
| 1 minute | Nearest minute | 8:57 AM | 5:03 PM |
| 5 minutes | Nearest 5-minute mark | 9:00 AM | 5:05 PM |
| 6 minutes | Nearest 6-minute mark | 9:00 AM | 5:06 PM |
| 15 minutes | Nearest quarter-hour | 9:00 AM | 5:00 PM |
The fairness principle
Rounding must be neutral — it cannot systematically benefit the employer. If rounding always rounds down at clock-in and down at clock-out, the employer systematically gains time. This is called pyramiding and is illegal in many jurisdictions.
The correct approach is to round to the nearest increment:
| Actual time | Nearest 5 minutes | Direction |
|---|---|---|
| 8:57 AM | 9:00 AM | Rounds up (employee gains 3 minutes) |
| 8:52 AM | 8:50 AM | Rounds down (employee loses 2 minutes) |
| 5:03 PM | 5:05 PM | Rounds up (employee gains 2 minutes) |
| 5:02 PM | 5:00 PM | Rounds down (employee loses 2 minutes) |
Over time, rounding up and rounding down should roughly balance out.
Rounding Rules by Jurisdiction
United Kingdom
The UK does not have a specific statutory rounding rule. However:
- The Working Time Regulations require accurate records of working time
- Rounding must not reduce recorded hours below the 48-hour weekly average threshold
- Rounding must not eliminate rest break entitlements (20-minute break for 6+ hour shifts)
- Employment contracts may specify rounding rules
- The 2019 CJEU ruling requires an “objective, reliable and accessible” recording system
Best practice in the UK: Round to the nearest 5 minutes. Do not round in a way that reduces total hours worked or eliminates break entitlements. Document the rounding policy in the employment contract or employee handbook.
United States
The US Department of Labor addresses rounding under the Fair Labor Standards Act (FLSA):
- The 7-minute rule is the most common approach: times within 7 minutes of the nearest increment are rounded to that increment
- Rounding must be neutral — it cannot systematically favour the employer
- The employer must track the actual time worked over the full pay period, not just individual days
- Some states have additional restrictions
The 7-minute rule explained:
| Actual time | Nearest 15 minutes | Rounds to | Difference |
|---|---|---|---|
| 8:53 AM | 8:45 AM / 9:00 AM | 9:00 AM | +7 min |
| 8:52 AM | 8:45 AM / 9:00 AM | 8:45 AM | -7 min |
| 5:08 PM | 5:00 PM / 5:15 PM | 5:15 PM | +7 min |
| 5:07 PM | 5:00 PM / 5:15 PM | 5:00 PM | -7 min |
State-specific considerations:
| State | Rounding restriction |
|---|---|
| California | De minimis rounding permitted; some courts have questioned rounding for meal periods |
| New York | No specific prohibition; federal rules apply |
| Illinois | Must be neutral; some case law limiting rounding |
| Massachusetts | Must be neutral; court scrutiny of rounding practices |
Australia
Australian rounding rules are governed by Modern Awards and the Fair Work Act:
- Most Modern Awards allow rounding to the nearest 5 minutes or 10 minutes
- Rounding must not result in the employee being paid less than the minimum hourly rate
- Some Modern Awards specify the rounding increment (e.g., 6-minute increments for some awards)
- The Fair Work Act requires records of hours actually worked
Common award rounding:
| Award category | Typical rounding | Notes |
|---|---|---|
| General retail | Nearest 5 minutes | Must not reduce below minimum hours |
| Hospitality | Nearest 6 minutes | Aligns with 10-minute break calculations |
| Manufacturing | Nearest 5 minutes | Must be documented in time records |
| Professional services | Nearest 5 minutes | Must be neutral |
How to Configure Rounding Correctly
Step 1: Choose your increment
| Team type | Recommended increment |
|---|---|
| Office-based (fixed hours) | 5 minutes |
| Shift-based (award-covered) | 6 minutes (aligns with break calculations) |
| Hourly workers (US) | 15 minutes (7-minute rule) |
| Field workers | 5 minutes |
Step 2: Configure the rounding direction
Always round to the nearest increment, not always up or always down:
| Setting | Correct | Incorrect |
|---|---|---|
| Clock-in rounding | Nearest increment | Always round down (employer gains) |
| Clock-out rounding | Nearest increment | Always round down (employer gains) |
| Both directions | Yes | No |
Step 3: Set a daily or pay period check
Even with correct rounding, some days will round in the employer’s favour and some in the employee’s favour. Over a pay period, the net effect should be close to zero. Monitor this:
- Track total actual hours vs total rounded hours per pay period
- If the net difference consistently favours the employer, adjust the rounding rule
- Document the monitoring process
Step 4: Communicate the policy
Employees should know:
- What rounding increment is used
- How rounding works (nearest increment, not always up or down)
- Where to find the rounding policy (employee handbook, employment contract)
Common Rounding Mistakes
| Mistake | Risk |
|---|---|
| Rounding always in employer’s favour | Systematic underpayment — potential tribunal/FLSA claim |
| Rounding to 15-minute increments | May lose 14 minutes of actual work time per shift |
| Not documenting the policy | Disputes about what was agreed |
| Rounding break times differently | Inconsistent application creates compliance risk |
| Not monitoring net effect | Rounding bias goes undetected |
How Leave Balance Handles Rounding
Leave Balance records attendance with precise timestamps and can be configured with rounding rules that round to the nearest configured increment. The system ensures rounding is applied neutrally — to the nearest 5 minutes (or other configured increment) — and provides reports showing both actual and rounded times.
Features relevant to rounding compliance:
- Configurable rounding rules — set the increment and direction
- Transparent records — actual and rounded times are both visible
- Audit trail — every rounding decision is recorded
- CSV export — rounded times for payroll, actual times for audit

Frequently Asked Questions
Is clock-in rounding legal?
Rounding is legal in most jurisdictions provided it is neutral — it cannot systematically favour the employer. The rounding must round to the nearest increment (not always up or always down), and the net effect over a pay period should be close to zero.
What is the 7-minute rule?
The 7-minute rule is a US FLSA guideline: times within 7 minutes of the nearest 15-minute increment round to that increment. For example, 8:53 AM rounds to 9:00 AM (within 7 minutes), but 8:52 AM rounds to 8:45 AM (beyond 7 minutes). The rule must be applied neutrally.
Can I round break times?
Rounding break times is subject to the same fairness principle. If break times are rounded in a way that reduces the employee’s total break below the legal minimum (e.g., 20 minutes in the UK), the rounding is non-compliant. Check your jurisdiction’s rules on break time rounding.
How does rounding affect overtime?
If rounding systematically reduces recorded hours, it can push overtime hours below the overtime threshold. For example, if an employee works 40 hours and 8 minutes, rounding to 40 hours eliminates the overtime. Rounding must not be used to avoid overtime obligations.
What rounding increment should I use?
5 minutes is the most common and widely accepted increment. For Australian businesses covered by certain Modern Awards, 6-minute increments may be more appropriate. For US businesses using the 7-minute rule, 15-minute increments are standard. Choose the increment that aligns with your jurisdiction and industry.
