The exact method behind this answer

CalculationTime keeps the method visible so the number can be checked instead of blindly trusted.

Paid shift minutes = elapsed minutes − unpaid break minutes. Overtime minutes = max(0, paid shift minutes − regular threshold × 60). Regular minutes = paid shift minutes − overtime minutes. Gross pay = regular hours × base rate + overtime hours × base rate × overtime multiplier.

Assumptions used

What this answer assumes

Use this as a clean arithmetic check before applying payroll rules.

  • The regular-hours threshold is entered by the user and must come from the rule you are checking.
  • Break minutes are unpaid and deducted before overtime is measured.
  • Gross pay is an estimate before tax, leave loading, allowances, superannuation, national insurance, rounding and deductions.
  • This is a planning calculator using transparent general arithmetic, not a legal payroll ruling.

How to use the result well

Master’s Tip: use this for one-shift what-if checks only. For a full week, daily entries, multiple penalty rates or jurisdiction modes, use the Payroll Time Card page instead.

Formula

Paid shift minutes = elapsed minutes − unpaid break minutes. Overtime minutes = max(0, paid shift minutes − regular threshold × 60). Regular minutes = paid shift minutes − overtime minutes. Gross pay = regular hours × base rate + overtime hours × base rate × overtime multiplier.

Worked example

8:00 to 18:00 is 600 elapsed minutes. Minus 30 minutes break = 570 paid minutes. A regular 8-hour threshold is 480 minutes, so overtime is 570 − 480 = 90 minutes. At 25/hour and 1.5× overtime, gross pay is 8 × 25 + 1.5 × 25 × 1.5 = 256.25.

Regional and unit assumptions

Defaults assume an 8-hour standard day because it is a common planning threshold. No named payroll standard is claimed; change the threshold to match the workplace, award, contract or local convention you are checking.

Assumptions and limitations

Methodology & Accuracy

How this calculator is checked

CalculationTime pages are built around visible arithmetic: the formula, assumptions, worked example and practical limitations are shown so the result can be checked rather than simply trusted.

Formula used

Paid shift minutes = elapsed minutes − unpaid break minutes. Overtime minutes = max(0, paid shift minutes − regular threshold × 60). Regular minutes = paid shift minutes − overtime minutes. Gross pay = regular hours × base rate + overtime hours × base rate × overtime multiplier.

Standard or basis

Defaults assume an 8-hour standard day because it is a common planning threshold. No named payroll standard is claimed; change the threshold to match the workplace, award, contract or local convention you are checking.

Where a calculator follows a named legal, trade or industry standard, that standard is cited visibly. Otherwise the page uses transparent general arithmetic and states its limits.

Questions

Is overtime calculated before or after breaks?

This calculator deducts unpaid breaks first, then compares paid time with the standard-hours threshold.

What if I worked less than the standard day?

Overtime is zero. The result only counts paid time above the threshold.

Can this calculate overtime pay?

Yes, as a simple gross-pay estimate. Enter the base hourly rate and overtime multiplier, then verify the governing payroll rule separately.

Which standard-hours threshold should I use?

Use the threshold from the contract, award, employer policy or local law you are checking. The default 8-hour value is only a planning example.

Can weekly overtime change the answer?

Yes. A shift may have no daily overtime but still contribute to weekly overtime once the full pay period is counted.

Calculation note

Overtime calculations combine simple time arithmetic with workplace rules. This page shows the arithmetic first: paid shift minutes minus a chosen standard threshold. Legal entitlement, rate multipliers and weekly totals belong to the governing rule set, not to a generic calculator.

Overtime starts with paid minutes, not clock span

A ten-hour clock span is not automatically ten paid hours. Unpaid breaks are deducted before this calculator compares the paid total with the selected standard-hours threshold.

The threshold is a rule choice

The same paid shift can produce different overtime totals under a 7.5-hour, 8-hour, 10-hour or weekly threshold. The sensitivity table on this page shows that change so the calculation is not mistaken for a legal decision.

Time and pay are separate questions

This calculator reports overtime duration only. Overtime pay may depend on the base rate, multiplier, day of week, public holidays, industry awards, employment contracts and local payroll law.
