Free Overtime Tracker Excel Template
Log every overtime hour with the reason it happened. Most overtime is the symptom of a fixable scheduling problem — the data reveals which.
What you get
Working OT tracker by operator, work center, and reason. Cost rollup with year-over-year trend. Surfaces whether OT is one-off urgency or systemic understaffing.

Why manufacturers still use Excel for this
Overtime is the easiest expense to track and the hardest expense to control. Payroll captures the dollars; nobody captures the why. Without the why, you cannot tell whether last week's overtime was unavoidable (genuine demand spike) or a symptom of poor scheduling (avoidable).
This template forces a reason code on every OT event. Patterns emerge quickly: 40% of OT is "rush order from customer X" (sales-driven), 25% is "machine breakdown recovery" (maintenance-driven), 20% is "schedule fell behind" (planning-driven), 15% is "absence coverage" (workforce-driven). Each reason has a different fix.
After 90 days of disciplined logging, the largest reason becomes obvious. Most shops can cut OT 20–30% by attacking just the top reason — not by clamping down on overtime authorization (which usually fails), but by fixing the upstream cause.
What's inside the template
OT event log
Date, operator, work center, OT hours, reason code, approver, OT cost (hours × premium rate).
OT reason code dictionary
Pre-built code list: rush order, breakdown recovery, schedule fell behind, absence coverage, customer change, supplier delay, planned project.
Weekly cost rollup
Total OT hours and cost by week. Year-over-year comparison surfaces trends the weekly view hides.
OT by reason Pareto
Total OT hours by reason code, sorted by impact. Drives the improvement project list.
OT by work center
Identifies whether OT is concentrated in specific work centers (capacity problem) or spread across the shop (systemic planning problem).
Authorization audit
OT hours by approver, with patterns flagged — same approver authorizing OT across multiple unrelated reasons usually signals approval-rubber-stamping.
How to use this template
A practical walkthrough — five steps from blank spreadsheet to a working schedule.
- 1
Require a reason code at authorization
The OT approval workflow should require selecting a reason from the dictionary before approval. Without that gate, reasons get backfilled inaccurately or not at all.
- 2
Capture at the event, not in payroll
Payroll has the hours; payroll does not have the why. Capture the why at the work-center level when the OT is worked, not 2 weeks later when payroll runs.
- 3
Review monthly with planning and ops
The reason Pareto is the agenda for the monthly OT review. The top reason gets a 60-day improvement project; everything else gets monitored.
- 4
Track the trend after intervention
When you fix a reason (e.g., add safety stock to eliminate "supplier delay" OT), the trend chart confirms it worked. No trend improvement = wrong root cause.
When you outgrow this template
Excel is the right answer for early-stage scheduling — until it isn't. Here are the warning signs that you need a real production scheduling tool.
If three or more of these apply, you have outgrown Excel scheduling. The good news: you do not have to leave Excel behind. Resource Manager for Excel (RMX) is a real finite-capacity scheduling engine that runs as an Excel add-in — so your team keeps the interface they know while gaining the scheduling power of a dedicated APS tool.

How is "premium" overtime cost calculated?+
OT cost = hours × (base rate × 1.5) for time-and-a-half jurisdictions, or × 2.0 for double-time situations. The template uses configurable multipliers per operator type. The full OT cost is not just the premium — it is the entire hourly rate during overtime, with the premium portion being the extra cost vs straight time.
What is "good" overtime vs "bad" overtime?+
Good OT covers genuine demand spikes you could not have predicted (sudden customer pull-in). Bad OT covers systemic problems (chronic understaffing, poor scheduling, predictable supplier delays). The reason codes separate them; the action plan differs.
Should I authorize OT to recover from a missed schedule?+
Almost never — but most shops do this routinely. OT to recover usually means the original schedule was unrealistic, and OT papers over the planning problem without fixing it. The honest fix is to plan against real capacity. The tracker surfaces this pattern.
How do I reduce overtime without hurting throughput?+
Fix the top reason in the Pareto. If "supplier delay" causes 40% of OT, fix supplier reliability or carry buffer stock. If "schedule fell behind" causes 30% of OT, fix the schedule (finite capacity vs infinite capacity planning). Reducing OT by management decree without fixing the cause usually backfires.
