Cost of downtime calculator · Manufacturing performance platform · MES, OEE, CMMS & AI Put a price tag on your hidden factory. See what you can recover.

Three numbers and two clicks are enough. The calculator prices your production losses the way Fabrico's financial impact module does, then shows how much of that cost MES and OEE software with CMMS built in can recover on your lines.

  • ROI in 3 to 6 months for most FMCG customers
  • Pilot line live in days
  • Built on R.C. Hansen's OEE method

Cost of downtime calculator

What your losses cost, and what MES, OEE and CMMS can recover

Start with your bottleneck lines, the ones that set plant output. The sample is an FMCG plant at industry-average figures; change any number and the result updates.

Your bottleneck lines
€

From these lines. An estimate is fine.

%

Selling price minus cost of goods sold.

%

Not measured? Most plants run at about 60%.

How do these lines run?

Can you sell more output from these lines?

If you can't sell it, recovered capacity comes back as fewer overtime and weekend hours, not as stock.

Refine the estimate Optional

How much of each loss can you cut in the first year?

Typical cuts breakdowns and changeovers by 20%, small stops and operator stops by 15%, and scrap and waiting by 10%: OEE up by about 10% in a year, the pace R.C. Hansen describes. Cautious halves the cuts; ambitious adds half again.

Labor, spare parts and contractors. Prices the repair costs you save by planning more of the work (CMMS). Enter 0 to leave it out.

€/ hour

Financial impact

Your OEE losses with a price tag, ranked by recoverable value

If a loss has no price tag, it has no priority. These are the formulas Fabrico's financial impact module runs minute by minute on every line, applied to your numbers.

Your top three: changeovers · small stops and slow cycles · breakdowns. Together they hold 74% of the recoverable value. Hansen’s rule: no more than three key projects at a time, bottlenecks first.

The hidden factory

Recover production capacity before you buy a new line

R.C. Hansen compares an OEE program with adding capacity: the program costs a fraction of the capital, takes months instead of years, and a new line may only run at the OEE you have today.

Capital project timings and the OEE caveat are from Hansen, chapter 3.

The principle

Recovered capacity is for meeting demand from the equipment you already have, not for building stock. That is why the calculator asks whether you can sell more.

Method

How the OEE and maintenance calculation works

A first look a finance team can follow, built on the business-case method in R.C. Hansen's Overall Equipment Effectiveness. Every assumption is listed here.

  1. Classify every minute

    OEE plus all losses equals 100% of scheduled time, split into six loss groups as in Hansen's worked example: breakdowns, changeovers, small stops and slow cycles, operator, procedure and material stops, scrap and rework, and waiting.

  2. Cut the losses, recompute OEE

    OEE = availability × performance × quality, before and after the first-year cuts. Production output rises in step with OEE.

  3. Value the recovered output

    If you can sell it: extra output × gross margin. If demand is flat: hours no longer needed × cost per hour. "Partly" splits it half and half. An hour stopped is priced as revenue at risk, profit and crew and energy.

  4. Add maintenance savings

    Reactive work falls from 40% to 30% of maintenance, and a reactive repair costs three times a planned one (Hansen: 3 to 5 times). That saves about 11% of your maintenance budget.

Counted once, kept conservative

  • Downtime is counted once, as recovered output, never again as a maintenance saving.
  • Extra output is valued at gross margin, so material and energy saved on less scrap are left out.
  • Gains stay flat after the first year, although Hansen notes they keep compounding.

FAQs

How accurate is this estimate?

It is a first look, built on R.C. Hansen’s OEE business-case method and your own numbers. In a pilot, Fabrico measures the real losses on one line, so the estimate is replaced by your own data within weeks. Review the result with your finance team before you decide.

What OEE should I enter if we don’t measure it?

Most plants that have not measured OEE run at about 60%. If you know the good output, the scheduled hours and the ideal rate of your bottleneck, OEE = good units ÷ (scheduled hours × ideal rate). The OEE calculator on fabrico.io walks you through it.

Why does the calculator ask whether we can sell more output?

Because recovered capacity is only worth its margin if customers buy it. If demand is flat, the same gain comes back as fewer overtime and weekend hours. Hansen calls these the “sell everything” and “same output” cases; the real value usually sits between them.

Is downtime counted twice, in OEE and in maintenance?

No. Shorter breakdowns are counted once, as recovered output. The maintenance (CMMS) saving covers only repair costs: more of the work planned, less of it reactive.

Why doesn’t the calculator show a payback?

Because Fabrico is quoted per plant, for the modules, lines and sites you choose. Use the opportunity as the size of the prize. In a 30-minute call we show what a quote for your plant includes, and a pilot line is live in days.

Where do my numbers go?

Nowhere, unless you choose to send them. The calculator runs in your browser. If you contact us from this page, you can attach your results so we can prepare for the call.
