About Kaizen Saving Estimate Calculator

A kaizen saving is time saved per unit x annual volume, converted to hours and valued at the fully loaded labour rate. Payback in months follows from implementation cost against annual saving. Small per-unit savings become large at volume: twelve seconds on 400,000 units is over 1300 hours a year.

Formulas

Kaizen saving

Hours released = time saved (s) x volume / 3600; saving = hours x labour rate

Payback

Payback months = implementation cost x 12 / annual saving

Worked example

With the default values below, Kaizen Saving Estimate Calculator returns Annual Saving of $560,000.00. 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 saving real if headcount does not fall?

Only if the released hours are used for something valuable — more output on a constrained line, or redeployment. Otherwise the saving is capacity, not cash, and should be reported as such.

Should the labour rate include overheads?

Use the fully loaded rate including benefits, supervision and facility overhead where headcount genuinely changes. For capacity release on a constrained line, use contribution per unit instead.
