Overtime Calculator
Calculate overtime pay, hourly rate and total monthly pay from your basic salary
Overtime Formula
Hourly Rate = Monthly Basic / (Working Days — Hours/Day)
OT Rate = Hourly Rate — Multiplier
OT Pay = OT Rate — OT Hours
Total Pay = Regular Pay + OT Pay
Real-Life Guide to Using the Overtime Pay
Overtime earnings calculation. Use the examples and checks below to turn the number into a practical decision.
When this calculator is useful
Hourly-wage and shift workers who put in extra hours beyond their standard shift, or payroll staff verifying overtime dues, use this to compute what the extra hours are worth in rupees.
For most people, the best way to use the Overtime Pay is to try the real case first, then change one input at a time. That makes the trade-off visible. For example, with a loan calculator you can change tenure while keeping the same rate; with an investment calculator you can change return assumption while keeping the same monthly contribution; with a health, education or measurement calculator you can check how much one input changes the final category.
The result should answer a practical question: Can I afford this? How much should I save? Is this score enough? Is this measurement within range? What is the safer or cheaper option? If the output does not answer the decision clearly, adjust the inputs until the scenario matches your real situation.
Practical Advice
Use the Overtime Pay as a planning tool, not just a number generator. Write down the inputs you used, because the final answer is meaningful only when you remember the assumptions behind it.
If the decision affects money, health, tax, safety, academics or legal compliance, keep a second check ready. That second check may be a bank quote, payslip, official rule, prescription, site measurement, mark sheet or invoice.
Common Mistakes
- Applying the overtime multiplier to gross salary per hour instead of the basic+DA hourly rate, which most overtime rules under applicable labour law are actually based on.
- Assuming every employee who stays late is legally entitled to overtime pay — many salaried managerial and supervisory staff are typically excluded from statutory overtime provisions.
- Using a flat daily rate divided by 8 hours when the actual standard working hours per day or week defined by the applicable establishment rules may differ (some states/industries define different standard hours).
- Forgetting that overtime is commonly paid at twice the ordinary hourly rate under many applicable labour laws, not at 1.5x as is common in some other countries' rules.
- Not distinguishing between hours worked beyond the daily limit versus beyond the weekly limit, since some rules trigger overtime based on crossing either threshold, whichever gives the employee a better outcome.
How to Interpret Results
The result shows extra pay owed for hours worked beyond standard shift length, calculated at the overtime multiplier on your hourly rate; compare it against your payslip's overtime line to check your employer used the correct hourly base and multiplier.
A good interpretation looks at both the main result and the supporting values. If a page shows totals, ratios, categories, schedules or warnings, read those together instead of focusing only on the biggest number.

What is an Overtime Calculator?
Overtime pay is the additional compensation paid to employees for hours worked beyond standard working hours (typically 8 hours/day or 48 hours/week as per the Factories Act). Overtime is typically paid at 1.5� the normal rate (time and a half) or 2� (double time) depending on company policy.
For salaried employees, the overtime hourly rate is derived from monthly salary: Hourly Rate = (Monthly Basic) / (Working Days — Hours per Day). This calculator computes overtime earnings based on your monthly salary, overtime hours, and applicable multiplier.
help_outlineHow to Use the Overtime Calculator
- Enter your Monthly Basic Salary — only the basic component (not total CTC or gross salary). Basic is used for OT calculation as per the Factories Act. Typically 40�50% of gross salary.
- Enter Working Days per Month — standard is 26 days (excluding Sundays) for a 6-day work week, or 22 days for a 5-day week. Verify with your employment contract or HR policy.
- Enter Regular Working Hours per Day — typically 8 hours. Some factories work 9-hour shifts; adjust accordingly to get the accurate hourly rate.
- Enter Overtime Hours worked in the current month — total extra hours beyond regular working hours this month (e.g., 20 hours over 10 days = 2 extra hours/day).
- Select the Overtime Rate Multiplier (1.5� standard, 2� double time for Factories Act workers, or enter a custom rate). Click Calculate Overtime to see hourly rate, OT pay, and total monthly pay.
Benefits
- Derive your exact hourly rate from monthly salary — useful for comparing consulting/freelance rates
- Know your overtime pay precisely before the payslip arrives — verify employer's calculation
- Confirm if employer applied the correct multiplier and hours — avoid underpayment of OT
- Compare 1.5� vs 2� scenarios — understand your legal entitlement under the Factories Act vs company policy
- Pay breakdown chart shows what percentage of your total monthly pay is regular vs overtime
Key Terms
- Basic Salary
- The fixed, non-variable core component of your salary package — used to calculate OT pay, PF (12% of basic), gratuity (15/26 — basic), and leave encashment. Excludes HRA, allowances, and variable pay.
- Hourly Rate
- Monthly Basic / (Working Days — Hours/Day). For ₹30,000 basic / (26 days — 8 hours) = ₹144.2/hour. This is the regular rate — OT rate multiplies this by the applicable factor.
- OT Multiplier
- Factor applied to hourly rate for overtime: Factories Act mandates 2� for factory workers. Most office/IT companies pay 1.5� or straight time (1�) for salaried employees — check your employment contract.
- Factories Act, 1948
- Requires adult workers in factories to work max 48 hours/week or 9 hours/day. Overtime (anything beyond) must be paid at double the regular rate. Applicable to manufacturing units with 10+ workers.
- Compensatory Off (Comp-off)
- Equivalent time off given instead of overtime pay. Legally permissible only if agreed to; cannot replace mandatory Factories Act overtime pay in manufacturing. Service sector employees often accept comp-off.
