How to Calculate Overtime Costs (With Formula and Examples)
Overtime eats your margins faster than you think. Here's exactly how to calculate what it's actually costing you. with formulas, examples, and ways to cut it.
Multiply the employee's regular hourly rate by 1.5 for standard overtime (time-and-a-half). For example, an employee earning €15/hour would earn €22.50/hour for every overtime hour. Some countries and contracts use 2x for Sundays or holidays.
In most EU countries, overtime begins after the standard working hours defined by national law or collective agreement. typically 40 hours per week. Spain caps overtime at 80 hours per year. France starts overtime at 35 hours/week. Always check your specific country's labor law.
Not always. Standard overtime is typically 1.5x (time-and-a-half), but rates vary. Some collective agreements pay 1.25x for the first 2 overtime hours and 1.5x after. Sundays and holidays often pay 2x. Night shift overtime may have additional premiums.
The true cost is 25-40% higher than the wage premium alone. You're also paying increased employer taxes and social security contributions on overtime hours, plus absorbing costs from fatigue-related errors, higher accident rates, and reduced productivity per hour worked.
Better scheduling is the biggest lever. Most unplanned overtime comes from poor coverage planning, last-minute callouts, or uneven workload distribution. Cross-training employees, using part-time staff for peak periods, and publishing schedules earlier all reduce overtime without cutting service quality.

Most managers look at overtime as "time and a half" and leave it at that. But the actual cost of overtime includes employer taxes, social contributions, reduced productivity, and higher error rates that never show up on the paycheck.

Here's how to calculate what overtime is really costing you, and what to do about it.
Warning
If overtime is more than 10% of your total labor cost, you probably don't have
an overtime problem. You have a scheduling problem. For broader benchmarks,

$18,720/year is pure overtime premium. Better scheduling with Turnozo ($10/mo) can cut this significantly.
You're paying 1.5x for output that's worth 0.7x. The math doesn't work.
A Stanford study found that output at 70 hours per week is barely more than output at 56 hours. the extra 14 hours produce almost nothing. You're paying for presence, not production.
Error and accident costs
Fatigued workers make more mistakes. In manufacturing and hospitality, overtime-related errors can include:
Wrong orders or missed tasks
Safety incidents (workplace injury claims)
Customer service failures
Equipment damage from inattention
The US Bureau of Labor Statistics found that workers on overtime shifts have a 61% higher injury rate compared to regular shifts. Each incident carries direct costs (medical, legal) and indirect costs (replacement staff, morale).
How to calculate your team's total overtime cost
Here's a step-by-step method for figuring out what overtime is actually costing your business per month:
Step 1: Gather the data
For each employee, pull:
Total hours worked this month
Regular hours (up to 40/week or your standard)
Overtime hours (everything above standard)
Regular hourly rate
Step 2: Calculate direct overtime cost
Total overtime wages = Σ (Employee OT hours × Hourly rate × 1.5)
Step 3: Add employer burden
Employer burden = Total overtime wages × Employer contribution rate
(Typically 25-35% depending on your country)
True overtime cost = Overtime wages + Employer burden
Step 4: Calculate overtime as a percentage of total labor
Most overtime comes from reactive scheduling. someone doesn't show up, so someone else stays late. Publishing schedules 2+ weeks ahead, tracking employee availability, and having a structured shift swap policy prevents the cascading chaos that creates overtime.
2. Cross-train your team
If only one person can close the kitchen, they'll always work overtime when coverage is tight. Cross-training 2-3 people for each critical role gives you flexibility without overtime.
3. Use part-time staff for peaks
If your restaurant needs extra coverage from 6-9 PM every Friday and Saturday, that's 6 hours of predictable demand. A part-time hire at regular rate is cheaper than overtime for your full-timers.
4. Set overtime alerts
If you're tracking hours manually, you won't notice someone hitting 38 hours until they've already hit 45. Scheduling software that alerts you when someone approaches overtime lets you redistribute before it happens.
5. Stagger shift start times
Instead of everyone starting at 9:00 and some staying until 7:00, stagger starts: 7:00, 9:00, 11:00. Coverage extends naturally without anyone working more than 8 hours.
6. Address your top overtime earners
In most teams, 20% of employees account for 80% of overtime. Review who's consistently working extra hours and why:
Are they the only ones with a certain skill? → Cross-train others.
Do they volunteer because they want the money? → That's a compensation discussion.
Are they staying late to finish work that should've been done during the shift? → That's a process problem.
7. Track and review monthly
You can't reduce what you don't measure. Pull overtime reports monthly and review:
Total overtime hours and cost
Overtime by department
Overtime by day of week (pattern recognition)
Overtime by employee (identify repeat cases)
After 3 months of data, the patterns are obvious. Most overtime clusters around specific days, shifts, or events.
Tracking overtime with software
Manually tracking hours and calculating overtime in spreadsheets works until it doesn't. which is usually around 15 employees. After that, the risk of errors, missed overtime, and compliance issues grows fast.
Scheduling software that integrates time tracking with scheduling gives you:
Automatic overtime calculation based on your country's rules
Alerts before employees hit overtime thresholds
Reports showing overtime patterns by department and individual
Accurate data for payroll. no manual counting
Turnozo combines scheduling and time tracking in one tool. Essential is €9.99/month for up to 10 employees and one location (centro), with every feature included. Pro is €2.99/employee/month from employee 11 or the second location (centro), billed across the whole workforce.
The bottom line
Overtime isn't just "time and a half." When you add employer contributions, reduced productivity, increased error rates, and turnover costs, every overtime hour costs roughly 2x what a regular hour costs. not 1.5x.
For most small teams, the real cost of manual scheduling includes significant overtime that better planning could prevent. Before you approve another week of "just a few extra hours," run the numbers. You might find that a part-time hire, better cross-training, or proper scheduling software pays for itself in the first month.
