Overtime Calculator — Complete Guide & Instructions

Useful for factory workers, HR staff and anyone verifying an overtime line on a payslip.

Pro Tips for Best Results
- Use basic salary only — HRA, DA and allowances are normally excluded from the OT base rate.
- The Factories Act, 1948 sets OT at twice the ordinary rate — choose 2× when checking statutory compliance.
- Some employers compute hourly rate on 26 days rather than 30 — check your appointment letter's convention.
- Leave "OT Days" blank to see pay per OT day; fill it in to project the month.
Common Problems & Solutions
Check whether you entered gross salary instead of basic — OT is priced on basic pay, which is lower than gross.
The divisor is days × hours. Enter actual scheduled hours (e.g. 8) and working days (e.g. 26), not the OT hours, in the schedule fields.
The calculator prices what you select. If your shop-floor agreement says 1.5× but law says 2×, run both multipliers to see the difference.
