What is the Gross Pay Calculator?
This calculator works out your gross (pre-deduction) pay across three pay tiers: straight time (your regular hours), overtime, and double time. You supply the hours that fall into each tier, your base hourly rate, and the overtime and double-time multipliers, and it returns the rate per hour, hours, and pay amount for each tier plus a grand total. It is a universal arithmetic tool — it does not encode any country's tax or labor rules and does not decide when overtime applies.
How to use it
Enter your regular hours and base hourly rate. Then enter how many hours fall into the overtime and double-time tiers along with their multipliers (commonly 1.5 for overtime and 2 for double time). Choose how many decimal places to round hours to, then read the summary table. Blank hour fields count as zero; only the base rate is required.
The formula explained
The overtime and double-time hourly rates are derived from the base rate: OT rate = base rate \(\times\) OT multiplier, DT rate = base rate \(\times\) DT multiplier. Each tier's amount is its rate multiplied by its hours. Gross pay is the sum of the three amounts:
$$\text{Gross Pay} = (R \times H_{ST}) + (R \times m_{OT} \times H_{OT}) + (R \times m_{DT} \times H_{DT})$$
Worked example
Suppose you worked 40 regular hours at $20.00/hr, 5 overtime hours at 1.5\(\times\), and 2 double-time hours at 2\(\times\). Straight time = $$20 \times 40 = \$800.00.$$ Overtime rate = $$20 \times 1.5 = \$30.00,$$ so overtime pay = $$30 \times 5 = \$150.00.$$ Double-time rate = $$20 \times 2 = \$40.00,$$ so double-time pay = $$40 \times 2 = \$80.00.$$ Total hours = 47 and gross pay = $$800 + 150 + 80 = \mathbf{\$1{,}030.00}.$$
FAQ
Is this gross or net pay? Gross only — no taxes, withholdings, or deductions are subtracted.
Does it decide when overtime kicks in? No. You enter how many hours belong to each tier; local labor law and employer policy determine when overtime or double time applies.
Can I model other premiums? Yes. Set the multipliers to any positive value to model arbitrary premium-pay schemes.
