For Iran payroll, the core question is how much extra pay is due when a worker's approved hours exceed ordinary working time. Iran Labour Law Article 51 sets the ordinary daily working-hours limit at 8 hours, and ordinary weekly hours must not exceed 44 hours. Overtime under Article 59 requires the worker's consent and payment of 40% in addition to the wage for each ordinary hour.
The result gives you ordinary pay, overtime pay, and total gross pay before deductions or other allowances. It does not decide whether the schedule itself is lawful in every case. You still need to check daily overtime limits, shift-work averaging, Friday rest-day treatment, night-work premiums, hard or hazardous work restrictions, and any collective labor contract that gives benefits above the Labour Law floor.
Start with the worker's ordinary hourly wage. Pay ordinary hours at 1x until the applicable ordinary limit is reached. For standard weekly overtime, multiply overtime hours by 1.4 because Iran's Labour Law requires 40% in addition to the wage for each ordinary hour. The basic weekly formula is: ordinary pay plus overtime hours multiplied by ordinary hourly wage multiplied by 1.4.
Example: a worker earns 1,200,000 rials per hour and works 50 approved hours in a week with no special Friday, night, shift-work, or hazardous-work issue. Ordinary pay is 44 hours × 1,200,000 rials = 52,800,000 rials. Overtime pay is 6 hours × 1,680,000 rials = 10,080,000 rials. Total gross pay is 62,880,000 rials.
The biggest mistake is treating every hour above 44 as just another premium hour. Normal overtime assigned to a worker must not exceed 4 hours per day, except in exceptional cases by mutual agreement. Emergency overtime for accident prevention, damage recovery, or resuming work after mishaps or natural calamities can reach 8 hours per day, but it requires local labour-office notification within 48 hours.
Hard, hazardous, and underground jobs follow a stricter baseline: 6 hours per day and 36 hours per week, with overtime prohibited for workers doing dangerous, hard, or hazardous work. Shift work can exceed 8 hours in a day or 44 hours in a week, but total working hours over four consecutive weeks must not exceed 176 hours. These rules change whether the calculator result is usable for payroll approval.
A one-off calculation is enough when you have a single worker, a clear hourly wage, approved ordinary hours, approved overtime hours, and no special classification issue. It also works for checking an invoice line, confirming a payroll draft, or explaining why a weekly total changed after overtime was added. Keep the consent record and the daily schedule beside the calculation.
A managed workflow is better when overtime repeats, multiple people submit time, or billable work needs to flow into client invoices. Everhour Billing & Invoicing converts tracked billable time and expenses into invoices, calculates invoice amounts from rates while excluding non-billable tasks, and can export invoices to QuickBooks Online, Xero, or FreshBooks with status sync back to Everhour.

Use 44 ordinary hours per week for the standard Iran overtime calculation. Iran Labour Law allows daily hours to vary with worker or representative consent, but ordinary hours must not exceed 44 in a week. Hours above that weekly baseline are not automatically valid; overtime still requires worker consent and must fit the daily and job-category limits.
The overtime multiplier is 1.4x the ordinary hourly wage. Article 59 requires payment of 40% in addition to the wage for each ordinary hour, and it also requires the worker's consent. If the ordinary hourly wage is 1,200,000 rials, the overtime hourly rate is 1,680,000 rials.
Normal overtime assigned to a worker must not exceed 4 hours per day, except in exceptional cases by mutual agreement of the parties. Do not approve a weekly overtime total only by checking whether it exceeds 44 hours. The daily schedule matters because a week can have a correct total but still contain a daily overtime problem.
Friday is the paid weekly rest day, and workers who work on Friday receive 40% in addition to usual wages for not using the Friday holiday. Night work between 10 p.m. and 6 a.m. gives non-shift workers a 35% premium. Keep these premiums separate from ordinary weekly overtime unless your payroll policy or contract defines how they interact.
No. Hard, hazardous, and underground jobs are limited to 6 hours per day and 36 hours per week, and Article 61 prohibits assigning overtime to workers doing dangerous, hard, or hazardous work. For those workers, the main issue is not the 1.4x formula; it is whether overtime can be assigned at all.
Everhour Billing & Invoicing turns tracked billable time and expenses into invoices, calculates amounts from rates, and excludes non-billable tasks. After time is selected for an invoice, Everhour marks it as invoiced so the same approved hours do not appear again in a later invoice.
Everhour timesheets let users submit weekly project hours or working hours for approval. Managers can approve, reject, or partially approve submitted time, and approved time stays locked for regular members, which keeps payroll review tied to a controlled set of hours.
Track approved overtime, separate billable from non-billable work, and generate invoice-ready totals from rates and expenses. Everhour keeps invoiced time protected from reuse and connected to billing status.
