Order entry error cost calculator
What does keying customer orders into the ERP cost each month, and what do the errors add? Enter your order volume, the minutes an order takes, the share that go wrong, what an error costs to put right and the loaded hourly cost of the people doing it. The calculator returns the monthly hours and cost, split between entry and errors.
You priced the errors. Mirage removes the retyping behind them.
Customer orders from any inbox, read, checked and entered in your ERP without retyping. Send us a few orders and we send back a plan, no commitment.

Where each input comes from
- Orders per month
- The ERP's count of sales orders created manually over the last three months, divided by three. Exclude EDI and web orders that post without a person.
- Minutes per order
- A stopwatch on ten orders of normal complexity, from opening the email or PDF to the saved order, including the lookups (customer, item codes, prices, delivery date).
- Error rate
- Credit notes, order changes after confirmation and returns whose cause is an entry mistake (wrong item, quantity, price, address, date), over the same orders. Three months of credit notes usually give the figure.
- Cost per error
- The average cash cost of one such error: reshipping freight, restocking, a credit written off, an expedite fee, a penalty. Your logistics and finance teams have the components.
- Minutes to fix
- The time between the customer's call and the corrected order, across everyone involved. Often longer than the original entry.
- Loaded hourly cost
- Gross salary plus employer charges and benefits, divided by paid hours. Not the hourly wage alone.
The formula
entry hours = orders × minutes per order / 60
cost of entry = entry hours × hourly cost
errors = orders × error rate
cost of errors = errors × (direct cost + minutes to fix / 60 × hourly cost)
cost per month = cost of entry + cost of errors
The result is the cost of the manual step as it runs today, in hours and in money, with the errors it produces priced at what they cost to repair. It is a baseline, not a saving: what an alternative would save depends on what share of the orders it takes over and on its own cost.
A worked example
A distributor enters 2,000 orders a month by hand at 6 minutes each: 200 hours. 3% of them carry an error, 60 orders, each costing 45 in freight and credits plus 20 minutes to fix. At a loaded 35 per hour: entry 7,000; direct error cost 2,700; rework 20 hours, 700. Total 10,400 a month, 124,800 a year, 220 hours or 1.4 full-time equivalents, and a third of the cost is the errors.
What the figure does and does not include
- Included: the time of entry, the time of repair, and the cash cost of each error you entered.
- Not included: late deliveries that cost a customer, discounts given to keep one, the planning disruption of a wrong quantity. Those are real and larger, and they are not in the formula because they are not read from a document.
- The error rate is the most uncertain figure. If you do not have it, enter 1% and 5% and look at both results.
FAQ
How do I measure the cost of manual order entry?
Multiply the orders entered by hand each month by the minutes each one takes, convert to hours and multiply by the loaded hourly cost of the people doing it. Add the cost of the errors that entry produces: the orders later corrected or credited, times what each one costs to put right in cash and in time.
What is a typical order entry error rate?
There is no figure that applies to your company. Read yours from three months of credit notes, order changes after confirmation and returns whose cause was an entry mistake, divided by the orders entered in the same period. Companies that measure it are often surprised by it, in either direction.
What counts as the cost of an order entry error?
The cash spent to repair it (reshipping freight, restocking, credits written off, expedite fees, penalties) and the time of everyone who handled it, from the customer call to the corrected order. Lost customers and planning disruption are real too, but they are not read from a document, so the calculator leaves them out.
Why use the loaded hourly cost rather than the salary?
Because the hour costs the company more than the wage: employer charges, benefits, paid leave and the tools and space of the position. Finance usually has a loaded rate per role; using the bare wage understates the figure by a third or more.
Does this calculator tell me what automation would save?
No. It gives the cost of the manual step as it runs today. An automated intake takes over a share of the orders and has its own cost; the saving is the difference. The automation ROI calculator on this site takes it from there.
