How Overtime Pay is Calculated — The Standard Formula
In the United States under the Fair Labor Standards Act (FLSA), overtime begins when a non-exempt employee works more than 40 hours in a single workweek. Every overtime hour is paid at a minimum of 1.5 times the regular rate.
The Overtime Pay Formula (Used Worldwide)
Step 1: Overtime Rate = Regular Hourly Rate × 1.5
Step 2: Overtime Pay = Overtime Rate × Overtime Hours
Step 3: Weekly Total = (Regular Rate × 40) + Overtime Pay
1.5× vs 2× Overtime — When Each Rate Applies
Time and a Half (1.5×)
- ✓ US: hours over 40/week (FLSA)
- ✓ California: hours over 8/day
- ✓ Canada (ON): hours over 44/week
- ✓ Australia: first 2 overtime hours
- ✓ Most UK contracts: standard OT
Double Time (2×)
- ✓ California: hours over 12/day
- ✓ California: 7th consecutive workday
- ✓ Australia: after 2 OT hours (most awards)
- ✓ Some UK contracts: bank holidays
- ✓ Many union agreements: Sundays
The 2025 Overtime Tax Deduction — A New Benefit Most Workers Don't Know About
Starting with the 2025 tax year (reported on your 2026 federal return), US workers can deduct the overtime premium — the extra 0.5× portion of overtime pay — from their federal taxable income. This deduction runs through 2028.
- Single filers: up to $12,500 deductible from the overtime premium
- Married filing jointly: up to $25,000 deductible
- Phase-outs begin at higher income levels
- Applies to non-exempt workers across all industries
On $8,000 in overtime premiums for the year, a single filer could deduct all $8,000 — saving roughly $960–$1,760 in federal tax depending on their bracket.
Salaried Employees and Overtime — How It Works
Many workers assume that being salaried means no overtime. This is a widespread and costly misconception. Under the FLSA, salaried employees earning under $684/week ($35,568/year) are non-exempt and entitled to overtime pay.
To calculate overtime for a salaried non-exempt employee: divide the weekly salary by 40 hours to get the effective hourly rate, then multiply by 1.5.
Example: $650/week salary ÷ 40 hours = $16.25/hr effective rate. Overtime rate: $16.25 × 1.5 = $24.38/hr.
Industry-Specific Overtime — Construction, Healthcare & Trucking
Overtime rules apply universally to non-exempt workers, but some industries have additional complexity worth knowing:
- Construction: Most workers are non-exempt. Prevailing wage projects may mandate higher base rates, which increases the overtime premium accordingly.
- Healthcare / Nursing: Hospitals may use 14-day work period agreements under FLSA §7(j), which changes when overtime kicks in. Calculate carefully — many hospital nurses are owed back pay for misapplied rules.
- Trucking: Interstate truck drivers are generally exempt from FLSA overtime under the Motor Carrier Act exemption. However, intrastate drivers and those below 10,001 lb vehicles may qualify. California's rules are stricter.
- Retail: Non-exempt retail workers earn standard 1.5× after 40 hours. Commission-based retail workers have a different calculation method for their regular rate of pay.
