Overtime Pay Calculator

What is an overtime pay calculator?

An overtime pay calculator works out how much you earn for extra hours by applying a pay multiplier to your hourly rate, then adds it to your regular pay for a gross total. You enter your hourly rate, regular hours, overtime hours and a multiplier, and the tool returns four numbers: your overtime rate, overtime pay, regular pay and total pay.

The two common multipliers are 1.5 (time and a half, the standard US overtime premium) and 2 (double time, sometimes paid for holidays or hours past a daily cap). This page explains the exact formula the tool uses, walks through reproducible worked examples, and includes a reference table so you can sanity-check any paycheck.

How does the overtime calculator work?

The calculator uses four short steps. Each figure is gross — before tax:

• regular pay = hourly rate × regular hours
• overtime rate = hourly rate × multiplier
• overtime pay = overtime rate × overtime hours
• total pay = regular pay + overtime pay

Combined, the core method is overtime pay = rate × multiplier × OT hours, and total = regular pay + overtime pay.

Terms and units:

• Hourly rate — your gross wage per hour, in dollars (for example $20.00).
• Regular hours — hours paid at your normal rate, often 40 per week.
• Overtime hours — extra hours paid at the premium rate. Enter only the overtime hours here, not your total hours.
• Multiplier — 1.5 for time and a half, 2 for double time.

Examples

Example 1 — time and a half (1.5×)

At $20/hour, 40 regular hours and 10 overtime hours at a 1.5× multiplier:

1. Regular pay = 20 × 40 = $800.00
2. Overtime rate = 20 × 1.5 = $30.00/hour
3. Overtime pay = 30 × 10 = $300.00
4. Total pay = 800 + 300 = $1,100.00

Example 2 — double time (2×)

Same inputs as above — $20/hour, 40 regular hours, 10 overtime hours — but at a 2× (double time) multiplier:

1. Regular pay = 20 × 40 = $800.00
2. Overtime rate = 20 × 2 = $40.00/hour
3. Overtime pay = 40 × 10 = $400.00
4. Total pay = 800 + 400 = $1,200.00

The only change is the multiplier, which lifts the 10 overtime hours from $300 to $400.

Example 3 — a smaller week at 1.5×

At $18/hour, 40 regular hours and 6 overtime hours at 1.5×:

1. Regular pay = 18 × 40 = $720.00
2. Overtime rate = 18 × 1.5 = $27.00/hour
3. Overtime pay = 27 × 6 = $162.00
4. Total pay = 720 + 162 = $882.00

These figures match the calculator output exactly, so you can reproduce them by hand to check your own pay.

Overtime rate reference table

Read your overtime rate straight from your base wage. The table shows both the time and a half (1.5×) and double time (2×) rate, plus the pay for 10 overtime hours at each multiplier.

Hourly rate	1.5× rate	2× rate	10 OT hours at 1.5×	10 OT hours at 2×
$15.00	$22.50	$30.00	$225.00	$300.00
$18.00	$27.00	$36.00	$270.00	$360.00
$20.00	$30.00	$40.00	$300.00	$400.00
$22.00	$33.00	$44.00	$330.00	$440.00
$25.00	$37.50	$50.00	$375.00	$500.00
$30.00	$45.00	$60.00	$450.00	$600.00
$35.00	$52.50	$70.00	$525.00	$700.00

For example, double time at $25/hour for 10 hours is 25 × 2 × 10 = $500.00.

Common uses

• Checking a paycheck: confirm your employer applied the right multiplier to the correct number of overtime hours.
• Planning extra shifts: see what an additional 5 or 10 overtime hours adds before you agree to them.
• Comparing 1.5× vs 2×: quickly weigh a time-and-a-half week against a double-time holiday shift.
• Small-business payroll: estimate weekly labor cost once staff cross the 40-hour line.
• Budgeting: turn an expected overtime week into a concrete gross figure for your monthly plan.

Tips and common mistakes

• Enter only overtime hours in the OT box. If you worked 50 hours, put 40 as regular and 10 as overtime — not 50 in both fields, which double-counts your pay.
• Pick the correct multiplier. Time and a half is 1.5; double time is 2. Using 2 when you only earn 1.5 will overstate your pay by a third.
• Use your true regular rate. Non-discretionary bonuses, shift differentials and commissions may need to be folded into your weekly earnings first, which can push the regular rate above your base wage.
• Remember it is gross. The total is pre-tax; your take-home overtime is lower after income tax and FICA.
• Don’t average two weeks. Overtime is measured per workweek, so 30 hours one week and 50 the next still counts 10 overtime hours in week two.

Limitations and notes

This calculator gives an estimate of gross pay using a flat multiplier you choose. It does not compute taxes, blended rates for multiple pay rates, tipped-wage rules, or state-specific double-time tiers — it simply applies the rate, multiplier and hours you enter. Under the US Fair Labor Standards Act, federal law requires at least 1.5× for hours over 40 in a workweek, but daily overtime and double-time rules vary by state and contract. This tool is for general information only and is not legal, payroll or financial advice; for binding figures, check your pay stub or your state labor agency.
