How Overtime Pay Works
Overtime pay compensates hours worked beyond the normal schedule at a premium rate. The formula is: Overtime pay = Hourly rate × Multiplier × Overtime hours. At Rs 650/hour with 8 overtime hours at 1.5×, that is 650 × 1.5 × 8 = Rs 7,800 of extra pay for the week. Add regular pay (650 × 40 = Rs 26,000) for a Rs 33,800 weekly total.
The 1.5× rule — time and a half — is the global default, originating in American labour law and adopted as company policy across much of the private sector worldwide. It exists for a reason: extra hours cost you disproportionately (fatigue, lost evenings, health), so the premium partly compensates the real price you pay. The 2× rate (double time) typically applies to weekends, public holidays, or night shifts in many systems, and is the statutory norm in several countries including Pakistan’s factory legislation.
Note what the multiplier applies to: your ordinary hourly rate, usually basic pay divided by standard hours — not including allowances unless your contract says so. This is a common source of underpayment: employers who compute OT on a deflated base rate. Always check which rate your multiplier multiplies, not just the multiplier itself — the overtime pay calculator shows both figures separately so nothing hides.
Overtime Rules in Pakistan
Pakistani labour law treats overtime seriously on paper. Under the Factories Act 1934 (adopted into provincial law after devolution), a worker required to work beyond the normal daily or weekly limits is entitled to overtime at twice the ordinary rate of wages. Similar double-rate provisions appear in shops-and-establishments legislation covering retail and office workers, though thresholds and coverage vary by province.
The gap between law and practice is wide. Many private-sector employees — especially in offices, where the law’s coverage is murkier — receive 1.5×, a flat allowance, or nothing at all for late sittings. Enforcement is weak and most workers never claim. Knowing the statutory 2× figure matters because it is your starting position in any negotiation or complaint: you are not asking for a favour, you are asking for the legal minimum where the law covers you.
Practical steps: get your overtime policy in writing (offer letter, HR manual, or email confirmation). Keep your own log of extra hours — dates and times — because employer records have a habit of shrinking. And if your contract specifies 1.5× while the statute says 2× for your category of work, that is worth a conversation with a labour-law professional, not just HR.
Overtime Traps to Watch For
Unpaid late sittings normalized as culture. In many Pakistani offices, staying late is expected but never recorded. If it is regular, it is overtime — log it and raise it.
OT calculated on basic pay only. If allowances make up half your compensation, OT on basic alone can halve your real entitlement. Check your contract’s definition of wages for OT purposes.
Comp-off instead of pay, at bad rates. Time off in lieu is fine if genuinely equivalent, but one comp-off day for three late evenings is a pay cut disguised as flexibility.
Managerial exemptions misapplied. Some employers label everyone manager to dodge OT obligations. Titles do not decide coverage — the nature of your work and the applicable statute do.
Monthly salary hiding hourly theft. A fixed salary makes extra hours invisible. Convert your salary to an hourly rate, multiply by your real weekly hours, and see what each unpaid evening actually costs you.
Overtime Pay Calculator: Frequently Asked Questions
What is the standard overtime rate?
The most common standard worldwide is 1.5× the regular hourly rate, known as time and a half. In Pakistan, factory legislation provides for double the ordinary rate (2×) for covered workers, while many private employers apply 1.5× by policy. Weekend, night, and public-holiday work often attracts higher multipliers. Always check your contract first — this overtime pay calculator lets you select whichever multiplier actually applies to you.
What is the 1.5x rule for overtime?
The 1.5× rule means overtime hours are paid at one and a half times your normal hourly rate. If you earn Rs 600/hour, each overtime hour pays Rs 900. It originated in US labour law and is now the default company policy across much of the global private sector. Some employers and laws use 2× instead, especially for holidays. The calculator includes 1.5×, 2×, and 2.5× presets plus a custom field.
What does Pakistan labour law say about overtime?
Under laws such as the Factories Act 1934 and its provincial successors, workers required to work beyond normal hours are generally entitled to overtime at twice the ordinary rate of wages. Shops-and-establishments laws contain similar provisions for retail and office workers, with details varying by province. In practice many private employers pay 1.5× or nothing, and enforcement is weak — so get your employer’s policy in writing and keep your own log of extra hours.
How is the weekly overtime threshold decided?
The threshold is whatever your contract or the applicable law defines as normal working hours — commonly 40–48 hours per week in Pakistan depending on the sector. Hours beyond that threshold count as overtime. Some employers set daily thresholds (e.g., beyond 8 hours a day) instead of weekly ones. Check whether your workplace counts overtime daily or weekly, because the two methods can give different totals for the same week.
Can my employer refuse to pay overtime?
It depends on your contract and which law covers your work. Where statutes like the Factories Act apply, overtime at the prescribed rate is a legal entitlement, not a favour. But many office workers fall into grey areas where the contract governs — and if the contract is silent, employers often pay nothing. Document your hours, get policies in writing, and consult a labour-law professional before escalating. The calculator gives you the exact figures to support your case.
