Takt Time Calculator
How often you must finish one unit to meet customer demand.
Takt time
103.8
- Net available time
- 450 min
- Required output rate
- 34.7 units/hr
- Demand per shift
- 260 units
Takt time is the heartbeat a line should run at, derived entirely from the customer: available working time divided by the units the customer wants in that period. It is not a capability measure and it says nothing about what your equipment can actually do — it is a requirement you then compare your cycle time against.
The practical value is in that comparison. If your cycle time is below takt, you have slack and can absorb variation, or you are over-producing. If it is above takt, you will miss the shipment no matter how hard people work, and the fix has to be structural: split the work, add capacity, or extend the time available. This calculator gives you takt in seconds per unit alongside the required output rate in units per hour, so you can compare it directly against a stopwatch reading.
How the result is calculated
Takt time = (Available time − Planned breaks) ÷ Customer demand- Net available time = Shift length − planned breaks and meals
- Takt time (sec/unit) = Net available time × 60 ÷ Demand per shift
- Required output rate (units/hr) = Demand ÷ (Net available time ÷ 60)
Variables
| Symbol | Meaning | Unit |
|---|---|---|
T | Takt time | sec/unit |
Ta | Net available time | min |
D | Customer demand per shift | units |
Worked example
A single-shift cell works 480 minutes with a 30-minute unpaid meal break. The customer orders 260 units per shift.
- Net available time = 480 − 30 = 450 min
- Takt = (450 × 60) ÷ 260 = 27,000 ÷ 260
- Takt ≈ 103.8 seconds per unit
- Required rate = 260 ÷ 7.5 hours = 34.7 units per hour
The cell must complete one unit every 103.8 seconds. Any workstation with a cycle time above that becomes the constraint; workstations well below it will sit idle waiting, which is where you should rebalance work rather than asking operators to slow down.
What this calculation does not cover
- Takt time assumes demand is level across the shift. With highly seasonal or batch demand, calculate takt per product family or per demand period instead of blending everything into one average.
- Takt is a requirement, not a target for individual operators. Forcing every station to exactly takt removes the buffer that absorbs normal variation and usually increases both stress and defects.
- If the line runs multiple products with very different work content, a single takt number is misleading — use a weighted takt based on the demand mix, or level the schedule first.
- Takt excludes planned maintenance beyond the shift-level breaks. If maintenance consumes production time, subtract it from available time before calculating.
Frequently asked questions
What is the difference between takt time and cycle time?
Takt time comes from the customer: how often you must ship a unit. Cycle time comes from your process: how long a unit actually takes at a station. Takt is the target, cycle time is the reality. Comparing the two tells you whether you can meet demand and which station constrains the line.
Should I include planned downtime in available time?
No. Available time should contain only time you intend to produce. Planned maintenance, scheduled cleaning, breaks and meals are removed first. Unplanned downtime stays out of the calculation entirely — it is a capability problem that shows up when you compare measured cycle time against takt.
How do I calculate takt for a multi-shift operation?
Calculate it per shift using that shift’s available minutes and that shift’s demand. If demand is stable across shifts, the number will be identical and you can use one figure. If shifts differ in length or staffing, keep them separate — averaging a 480-minute shift with a 360-minute shift produces a takt that neither shift can actually run to.
