Decimal Hours for Small Business Timesheets

Small businesses can keep timesheets simple by recording normal start and finish times, checking unpaid breaks and paid hours, then converting the approved total into decimal hours for payroll.

For example, 08:30 to 17:00 with a 30-minute unpaid break gives 8h 00m of paid time, or 8.00 for payroll.

Employees do not necessarily need to enter decimal hours themselves. In many cases, the simplest process is: record normal clock time → check the paid hours → approve the timesheet → convert the final total for payroll.

If you already know the paid duration, use the Hundred Hour Time Converter to convert hours and minutes into decimal hours.

Why small businesses use decimal hours

Decimal hours are useful because they are easier to work with in payroll systems, spreadsheets and calculations.

For example, 7h 30m = 7.50 hours. That decimal value can be:

  • added to other days
  • multiplied by an hourly rate
  • entered into payroll software
  • used in spreadsheets
  • used for internal costing

The amount of time has not changed. Only the format has changed.

For a fuller explanation, see Decimal Hours for Payroll Explained.

Should employees record hours and minutes or decimal hours?

For many small businesses, the easiest option is to let employees record normal start and finish times.

  • Start: 08:00
  • Finish: 16:30
  • Unpaid break: 30 minutes
  • Paid time: 8 hours
  • Payroll decimal: 8.00

This is often simpler than asking every employee to calculate decimal hours themselves.

It also reduces mistakes such as entering 7.30 when the employee actually means 7h 30m.

These are not the same. 7h 30m = 7.50 decimal hours, while 7.30 decimal hours = 7h 18m.

The original clock-time record is usually easier for employees to understand and easier for a manager to check.

What should a simple small-business timesheet include?

A basic employee timesheet does not need to be complicated. Useful fields include:

  • employee name
  • date
  • start time
  • finish time
  • unpaid break
  • paid duration
  • decimal hours
  • weekly total
  • approval or sign-off

The key is to record enough information to understand how the final payroll figure was reached.

Simple daily timesheet example

A straightforward daily record might look like this:

FieldExample
Start time08:30
Finish time17:00
Unpaid break30m
Paid time8h00m
Decimal hours8.00

The start and finish times are the source record. The decimal figure is the payroll-friendly version of the final paid time. Both can be useful.

A simple weekly timesheet process

A small business can use a straightforward workflow each week.

1. Employee records the working time

Record the actual start time, finish time and unpaid break.

2. Paid time is checked

Make sure the daily duration is correct and that unpaid breaks have been removed.

3. The timesheet is reviewed

A manager, supervisor or business owner checks any unusual entries.

4. Daily totals are confirmed

Each day should have a clear paid-time figure.

5. The week is totalled

Add the approved daily paid time.

6. The total is converted if necessary

If payroll uses decimal hours, convert the final hours and minutes.

7. The payroll figure is approved

Check the decimal total against the source timesheet before sending it to payroll.

This creates a clear audit trail from the original time record to the final payroll figure.

Why keep the original clock-time record?

The decimal result is useful for payroll, but the original start and finish times are useful for checking.

For example, imagine the payroll figure says 8.50 hours. That tells you the employee was paid for 8h 30m.

But it does not tell you whether the original shift was:

  • 08:00–16:30 with no unpaid break
  • 08:00–17:00 with a 30-minute unpaid break
  • 07:30–16:30 with a 30-minute unpaid break

Keeping the original clock times makes it easier to:

  • check discrepancies
  • review breaks
  • compare with rotas
  • correct mistakes
  • answer employee queries
  • verify how the payroll total was produced

Paper, spreadsheet or software?

A small business can manage timesheets in several ways.

Paper timesheets

Paper can work well for a very small team. It is simple and requires no software, but totals and decimal conversions need to be checked manually.

Excel or Google Sheets

A spreadsheet can automate daily totals, weekly totals, decimal conversion and employee summaries.

This can work well for a small team if the spreadsheet is designed carefully and checked regularly.

Time-tracking or payroll software

Software can become useful when the business has more employees, several locations, irregular shifts, multiple approvals or complex payroll rules.

The important point is not which system you use. It is that the process is consistent.

Keep the same process for everyone

Inconsistent timesheets create unnecessary errors.

A business should ideally use the same approach for all relevant employees. That means agreeing:

  • how start and finish times are written
  • how unpaid breaks are recorded
  • whether totals are hours and minutes or decimal hours
  • when the week closes
  • who approves the timesheet
  • how corrections are made
  • when any payroll rounding rule is applied

For example, allowing one employee to write 7:30, another to write 7.50 and another to write 7.30 decimal creates avoidable confusion.

One standard format makes checking much easier.

Who should do the decimal conversion?

A simple process is:

Employee

Records the original working times accurately.

Manager or supervisor

Checks the timesheet and confirms the paid duration.

Admin, payroll system or calculator

Converts the approved paid hours into decimal format if required.

This avoids expecting every employee to understand decimal-hour conversion.

What if the rota and timesheet do not match?

Do not automatically assume either figure is correct.

  • Scheduled time: 8h
  • Recorded paid time: 8h30m

The difference might be correct because the employee worked additional time. Or it might be caused by:

  • a missed break
  • an incorrect clock-out time
  • an entry mistake
  • an unapproved extension to the shift

Check the source information before finalising payroll.

The weekly payroll figure should come from the approved paid-time record, not from guesswork.

Weekly example from timesheet to payroll

Suppose the approved paid time for the week is:

DayPaid time
Monday7h30m
Tuesday8h15m
Wednesday7h45m
Thursday8h00m
Friday6h50m
Weekly total38h20m

If payroll requires decimal hours:

20 ÷ 60 = 0.3333…

So 38h20m ≈ 38.33 hours. The payroll-ready figure is therefore 38.33.

For the full weekly calculation method, see How to Convert Weekly Hours for Payroll.

Conversion is not the same as payroll rounding

Converting time into decimal hours is a mathematical process.

50 ÷ 60 = 0.8333…

So 7h50m ≈ 7.83 hours. That is the decimal conversion.

Payroll rounding is different. A business may have a separate policy about how clock-in or clock-out times are handled.

Any rounding rule should be applied consistently and should not be confused with the underlying time conversion.

Common small-business timesheet mistakes

Asking employees to calculate decimals without checking them

This can lead to mistakes such as 7h30m → 7.30 instead of 7.50.

Mixing clock time and decimal hours

Do not add values such as 7:30 + 8.25 without converting them into the same format first.

Missing unpaid breaks

An unpaid break should normally reduce the paid-hours figure.

Subtracting a break twice

If the daily paid total already has the break removed, do not subtract it again later.

Missing start or finish times

An incomplete record makes it difficult to verify the paid duration.

Letting different employees use different formats

Consistency makes checking much easier.

Rounding too early

Keep the source time exact for as long as possible.

Changing the source record without keeping a correction trail

If a timesheet is corrected, it should still be clear what changed and why.

Sending payroll an unchecked weekly total

A final review can catch simple mistakes before they become pay errors.

Small-business timesheet checklist

Before sending weekly hours to payroll, check that:

  1. start and finish times are recorded
  2. unpaid breaks are recorded
  3. paid duration is correct
  4. source records are retained
  5. unusual entries have been checked
  6. weekly totals are approved
  7. decimal conversion is correct
  8. payroll receives the correct final figure

Convert your timesheet hours

Once the paid time has been checked, use Hundred Hour to convert hours and minutes into decimal hours.

For example: 7h 30m becomes 7.50, and 8h 45m becomes 8.75

Frequently asked questions

Should employees enter decimal hours themselves?

Not necessarily.

For many small businesses, it is simpler for employees to record normal start and finish times and for the approved paid total to be converted later.

What should a small-business timesheet include?

A basic timesheet should usually include the employee name, date, start time, finish time, unpaid break, paid duration, weekly total and approval.

A decimal-hours column can also be included if payroll uses that format.

Is 7h30m the same as 7.30 hours?

No.

7h30m = 7.50 decimal hours, whereas 7.30 decimal hours = 7h18m.

Should I keep the original start and finish times?

Yes.

They make it much easier to check payroll totals and investigate discrepancies later.

Can I use Excel for small-business timesheets?

Yes.

A well-designed Excel or Google Sheets timesheet can work well for a small team and can automate many of the calculations.

When should a small business move to timesheet software?

Software may become useful when employee numbers, locations, working patterns or approval steps make manual systems difficult to manage consistently.

Should payroll rounding happen on the timesheet?

The original time record should normally remain accurate.

Any formal rounding rule should be applied consistently as a separate payroll process.

What is 8h45m in decimal hours?

8.75 hours, because 45 ÷ 60 = 0.75.

What is 38h20m in decimal hours?

20 ÷ 60 = 0.3333…, so 38h20m ≈ 38.33 hours.

Can a small business use decimal hours for invoicing as well as payroll?

Yes, decimal hours can also be useful for billable time and internal costing.

However, the timesheet and payroll process should remain consistent and easy to verify.
