About Setup Time Reduction Saving Calculator

Setup reduction releases line time worth the internal cost of that capacity. Annual saving is minutes saved per changeover x changeovers a year x cost per minute of line time, where cost per minute should reflect contribution lost, not just labour, whenever the line is capacity-constrained.

Formula

Setup reduction saving

Minutes released = (current setup - target setup) x changeovers per year; saving = minutes x cost per minute

Worked example

With the default values below, Setup Time Reduction Saving Calculator returns Annual Saving of $1,183,000.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation or tax into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Is the released time really worth money?

Only if the line is a constraint and the extra output can be sold. On a line with spare capacity the saving is limited to labour and consumables actually avoided.

How is a large setup reduction achieved?

Separate internal work that needs the machine stopped from external work that does not, convert internal to external, then simplify and standardise fixtures and fasteners. Most first-pass SMED projects cut setup by 50% or more with little capital.
