What Goes Into the Calculation
Manual entry
Work re-entered from a file into a program, from an e-mail into a spreadsheet, or from one system into another.
Correction work
Time spent tracking down missing information, wrong stock counts, order errors and inconsistent records.
Report preparation
Time spent pulling different sources together, checking them, and presenting them to management.
Direct loss
The monthly amount lost to stock discrepancies, late invoices, order errors, missed collections or work left waiting.
Keep Your Inputs Separate
Log every hour under a single heading. Don't add the same job to both manual entry and correction, or to report preparation as well; the calculation depends on not counting the same effort twice.
How to Read the Result
- 01
Current monthly load
The cost of the hours you entered, plus direct loss.
- 02
Improvement scenario
The rate you chose shows how much of this load you expect to change.
- 03
Budget comparison
Add the initial investment and monthly service cost to see the scenario's monthly effect, and a payback period if one applies.
Limits of the Calculation
The calculation multiplies monthly hours by average hourly cost, adds direct loss, and applies your chosen improvement rate to that total. Monthly service cost is subtracted from the scenario; if there's an initial investment, payback period is calculated from these inputs.
- Tax, financing cost, inflation and the time value of money are not included.
- Unmeasured outcomes such as revenue growth, new customer acquisition and strategic benefit are not added.
- The result is not a quote, a savings commitment or an accounting record.
Frequently Asked Questions
Which working hours should I enter in the calculator?
Enter time spent re-keying data, correcting errors and preparing reports in separate fields. Count each task once so the same labour does not appear under two headings.
Can I use the calculator without a direct-loss figure?
Yes. Leave direct loss at zero and build the scenario from time cost alone. Note in the decision file which costs the narrower result leaves out.
Is the improvement rate a savings promise from marqey?
No. It is your scenario assumption about which work could become standardised. Use a cautious and an optimistic rate to make the uncertainty visible.
Why can the calculated payback period differ from the real result?
The calculation excludes tax, financing, inflation, revenue growth and benefits you have not measured. It is only as reliable as the hours, costs, investment and monthly service values entered.
Does the calculator result replace a price proposal?
No. Product scope, migration, connections and implementation work are established separately. The calculator only compares today’s operating burden with a possible investment budget.
