TEEP Calculator: TEEP vs OEE and Hidden Capacity

This free TEEP calculator shows how much of all calendar time – 24 hours a day, 7 days a week – your equipment spends producing good parts at full speed. OEE tells you how well you use the time you planned; TEEP adds the question of how much time you plan at all. Together they reveal hidden capacity before you buy another machine.

Free TEEP Calculator

Enter the calendar hours of the period, the scheduled hours, planned stops and unplanned downtime, then ideal cycle time and units produced. The calculator returns TEEP, OEE, loading and OOE, shows where every calendar hour goes and how much hidden capacity a higher OEE or an extra shift would unlock – with an Excel export that keeps the formulas.

Key takeaways

  • TEEP = OEE × Utilization.
  • Utilization = planned production time ÷ all calendar time.
  • Low OEE → improve losses. Low utilization → add shifts or weekend time before investing.
  • TEEP is a capacity metric, not a shop-floor performance target.

Worked Example

A press runs two shifts of 7.5 planned hours, five days a week, with an OEE of 65%.

  • Planned time = 2 × 7.5 × 5 = 75 h; utilization = 75 ÷ 168 = 44.6%.
  • TEEP = 0.65 × 0.446 = 29.0% – the press is fully productive for about 49 hours a week.

Before buying a second press, the plant has two levers: raise OEE (better use of the 75 hours) or add planned time (a third shift or Saturday). Both are usually far cheaper than a new machine.

How to Use TEEP in Capacity Decisions

  1. Calculate OEE for the constraint machine – find it with bottleneck analysis.
  2. Calculate TEEP with the current shift model.
  3. Model scenarios: OEE +10 points, extra shift, weekend production.
  4. Compare cost per extra productive hour for each scenario with the cost of new equipment.

Common Mistakes

  • Using TEEP as a daily target for operators – they cannot influence the shift model.
  • Comparing TEEP between plants with different working-time regulations.
  • Ignoring OEE losses because “we can always add a shift”.

TEEP FAQ

What is a good TEEP?

It depends on the business model. A plant running 24/7 can reach high values; a single-shift operation will always show low TEEP even with excellent OEE.

What is OOE?

Overall Operations Effectiveness uses operating time (including planned maintenance) as the base. It sits between OEE and TEEP.

How do you calculate TEEP for a machine that runs 24/7?

If the machine is planned to run all calendar time, utilization is close to 100% and TEEP is practically equal to OEE. In that case, TEEP adds little insight – focus on OEE losses, because there is no unused shift time left to unlock.
