How the Overtime Calculator Works
Four simple steps to compute your overtime earnings.
Enter Hours Worked
Type the total hours you worked during the pay period. This includes both regular and potential overtime hours.
Set Your Rate
Enter your hourly rate and choose the overtime multiplier — 1.5×, 2×, or a custom value based on your employment rules.
Define Threshold
Set the overtime threshold — the number of hours after which overtime kicks in. The FLSA standard is 40 hours/week.

What Is an Overtime Calculator?
Understanding overtime pay rules and how they apply to your paycheck.
Overtime pay explained
An Overtime Calculator determines how much extra compensation you earn when you work beyond the standard number of hours. In the US, the Fair Labor Standards Act (FLSA) mandates that non-exempt employees receive at least 1.5× their regular rate for hours worked beyond 40 in a workweek.
The formula is simple: OT Pay = OT Hours × (Hourly Rate × OT Multiplier). If you earn $20/hour and work 48 hours, your 8 overtime hours are paid at $30/hour (20 × 1.5), giving you $240 in overtime pay on top of your $800 regular pay.
Daily vs weekly overtime
Some states like California have daily overtime rules: anything over 8 hours in a single day qualifies for 1.5× pay, and hours beyond 12 get double time (2×). Federal law only requires weekly overtime at the 40-hour threshold.
Who qualifies for overtime?
Non-exempt employees under the FLSA qualify for overtime pay. Exempt employees — typically salaried workers in executive, administrative, or professional roles — do not receive overtime under federal law.
When to Use an Overtime Calculator
Common scenarios where overtime calculations save you time and money.
Paycheck Verification
Verify your overtime pay matches what your employer calculated. Cross-check regular hours and OT hours to ensure you're paid correctly every pay period.
Payroll Processing
HR teams and payroll managers use overtime calculators to compute employee earnings accurately. Calculate overtime for entire teams across different pay rates and thresholds.
Budget Planning
Estimate your weekly or monthly earnings including overtime. Plan your finances by calculating how much extra you'll earn by working additional hours.
Labor Law Compliance
Ensure compliance with FLSA overtime rules, state regulations, and union agreements. Calculate the correct overtime multiplier and threshold for your jurisdiction.
Manufacturing & Shifts
Factory workers and shift employees often exceed 40 hours/week. Calculate overtime for rotating shifts, weekend work, and holiday double-time pay.
Freelance & Contract Work
Freelancers can use overtime rules to set premium rates for rush jobs. Calculate what to charge when clients need work done beyond your standard contracted hours.
Quick Overtime Calculation Examples
Common overtime scenarios and their results.
Standard 48-hour workweek
48 hours at $20/hr with 1.5× OT after 40 hours: Regular pay = $800 + OT pay = $240 = $1,040 total.
Heavy overtime week
55 hours at $25/hr with 1.5× OT: 40 regular hours ($1,000) + 15 OT hours at $37.50/hr ($562.50) = $1,562.50 total.
Double-time weekend
50 hours at $18/hr with 2× OT: 40 regular hours ($720) + 10 OT hours at $36/hr ($360) = $1,080 total.
Part-time with overtime
Some contracts set lower thresholds. 35 hours at $22/hr with OT after 30 hours: 30 regular ($660) + 5 OT at $33 ($165) = $825 total.
Frequently Asked Questions
Common questions about the Overtime Calculator.
Overtime is calculated by subtracting the overtime threshold (usually 40 hours/week) from total hours worked. Any hours above the threshold are multiplied by the overtime rate (typically 1.5× your regular hourly rate).
In the United States, the Fair Labor Standards Act (FLSA) sets the standard overtime threshold at 40 hours per workweek. Hours worked beyond 40 are paid at 1.5× the regular rate. Some states have daily overtime rules (e.g., California at 8 hours/day).
A 1.5× overtime multiplier means you earn one and a half times your regular hourly rate for every overtime hour. If you earn $20/hour, your overtime rate is $30/hour (20 × 1.5 = 30).
Yes. Double-time (2×) pay applies in some states and industries. In California, hours worked beyond 12 in a single day qualify for double-time pay. Some union contracts also specify 2× rates for holidays or weekends.
Add up all hours worked in the week. Subtract the overtime threshold (e.g., 40). Multiply regular hours by your hourly rate, then multiply overtime hours by your rate × the OT multiplier. Add both amounts for total pay.
