Changeover / SMED Savings Calculator
See how much production time and money you recover by cutting changeover minutes with SMED across every line, every week of the year. Your numbers stay in your browser.

How this is calculated
Every minute shaved off a changeover is a minute the line can run instead. Multiply that saving by how often you change over, across every line and every operating week.
SMED and honest caveats
- SMED means Single-Minute Exchange of Die. The core move is converting internal setup, which can only happen while the machine is stopped, into external setup that is prepared while it still runs. That is where most of the target reduction comes from.
- Recovered time is capacity, not automatic cash. The dollar figure assumes you can sell or use the extra runtime. If a line is not the bottleneck or demand is soft, the real value is lower.
- The target must be achievable. A target below your true external-setup floor will overstate savings. Use a number a pilot has actually hit.
- Guarded math. If the target is set above the current time, minutes saved is held at zero rather than showing a negative saving.
Reducing changeover time is a core lean practice. For the wider method and the eight wastes it attacks, read the lean manufacturing guide. To see how recovered availability flows into your overall score, use the OEE calculator.
Turn faster changeovers into real capacity
Harmony connects your machines, systems, and paperwork into one real-time operational layer, no rip-and-replace, so changeover time is measured accurately and the recovered hours this calculator estimates show up on the floor. Read the CLS case study.
