Time Card Calculator with Pay & Shift Rates

How to use it

Enter your base hourly rate under Pay setup.
Optional: tick Overtime rule and set a daily threshold, a weekly threshold, or both, plus the multiplier (it starts at 1.5). Leave a threshold blank to skip it.
Optional: add pay rules for any special rate you already know, such as Weekend, Night shift or Acting manager, and choose whether each is a multiplier, a flat addition or a rate override.
Add your shifts. Give each one a date, then enter start and finish times (or switch to Direct hours), the unpaid break in minutes, and tick any pay rules that apply. Each shift shows its hours and effective rate.
Read the estimated pay breakdown and total, then use Print summary if you want a copy of the breakdown.

Worked example

Say your base rate is $30/hr, and you set an overtime rule with a weekly threshold of 38 hours and the default ×1.5 multiplier. You add five shifts, Monday to Friday, each 9:00 am to 5:30 pm with a 30 minute unpaid break. That's 8 hours a day, 40 hours for the week.

Line	Hours	Rate	Pay
Ordinary hours	38.00	$30.00/hr	$1,140.00
Overtime	2.00	$45.00/hr	$90.00
Total	40.00		$1,230.00

Adding a weekend shift. Now add a Saturday shift, 9:00 am to 3:00 pm, and tag it with a rule called Weekend (a multiplier of ×1.25). That's 6 hours at $37.50/hr = $225.00, shown as its own Weekend line rather than as overtime. It doesn't count toward the 38 hour weekly threshold either, so the total becomes 46.00 hrs and $1,455.00.

How the pay rules work

Pay rules are optional. You name each rule and set its amount, and tick it on any shifts it applies to. There are three types:

Multiplier (×): multiplies the base rate, for example ×1.25.
Flat addition (+$/hr): adds a fixed amount per hour, for example an allowance.
Rate override ($/hr): replaces the base rate for that shift.

Order of calculation. An override sets the shift's rate first, multipliers apply to that, and flat additions are added last. For example, a $40/hr override plus a $2/hr allowance is $42/hr, so an 8 hour shift pays $336.00.

Only one override per shift. Ticking a second override swaps out the first.

Two or more multipliers on one shift. Choose Multiply together or Add loadings. On a $30/hr base with ×1.25 and ×1.5, multiplying gives $56.25/hr (8 hours = $450.00), while adding the loadings gives $52.50/hr (8 hours = $420.00). Pick whichever matches how your pay is actually worked out.

Tagged shifts and overtime. A shift tagged with any rule is paid entirely at that rule's rate and left out of automatic overtime, including the daily and weekly thresholds.

Minutes to decimal hours

The calculator shows hours as decimals, rounded to two places. To enter a shift in Direct hours, or to read a result, convert minutes to a decimal: decimal hours = minutes ÷ 60.

Minutes	Decimal hours
5	0.08
10	0.17
15	0.25
20	0.33
30	0.50
40	0.67
45	0.75
50	0.83

Frequently asked questions

How is overtime worked out?

Overtime is optional. Tick the overtime rule and set a daily threshold, a weekly threshold, or both. The calculator checks the daily limit first: hours over it on any date are overtime. Then, for each week, any remaining ordinary hours over the weekly limit become overtime too. Weeks run Monday to Sunday, and shifts on the same date are added together. The multiplier starts at ×1.5 and you can change it.

Why isn't my shift counted as overtime?

Usually one of four reasons: the overtime rule isn't ticked or has no threshold set, the shift has a pay rule tagged (tagged shifts are paid entirely at that rule's rate and skip automatic overtime), the shift has no date (it still counts, but only as ordinary hours), or you haven't gone over the threshold yet.

Does it handle overnight shifts?

Yes. If the finish time is earlier than the start time, it's treated as finishing the next day. For example, 10:00 pm to 6:00 am with a 30 minute break is 7.5 hours.

Does it know my award, penalty rates or public holidays?

No. It only uses the rates and rules you enter, and has no award, minimum wage or public holiday data for any country. For your legal entitlements in Australia, use the Fair Work Ombudsman's free calculator at calculate.fairwork.gov.au.

Is this my take-home pay?

No. It's gross pay, before tax, super or any other deductions.

Is my data saved or sent anywhere?

What you enter stays in your browser and isn't sent to a server. It also isn't saved, so refreshing the page clears everything. Use Print summary if you want to keep a copy of the breakdown.

Can I enter hours instead of start and finish times?

Yes. Switch a shift to Direct hours and type the hours worked, for example 7.75 for 7 hours 45 minutes. The table above converts minutes to decimals.
