Why Manufacturing Standard Costs Become Outdated and How to Fix Them

If it is obviously more expensive to produce this year, why isn’t the standard the same? The question is a conversation in the finance rooms of the business today, and the answer is that it was created in a world that is a moot point today. The route has been set; wages have increased, the freight lanes have been redone, and steel used in the area is more expensive.

Prices included in the bill of materials are based on a more stable supply chain, but do not represent the market prices. Many businesses use such figures as the foundation for information for controlling inventory, creating quotes, or calculating commissions. The financial decision makers would need to reevaluate these decisions prior to the end of the next reporting period when incorrect assumptions about cost may exist in the general ledger.

Decide Even if the Standard Is Broken or Just Stale

There are two types of standard cost drift, and it’s necessary to determine the nature of the drift before deciding what to do about it. Stale = Inputs (such as the price paid for some input or a wage rate change for some job) have changed from previous rolls. Broken” is when the method doesn’t agree with the way the part is manufactured: A new cell, a new alloy, a routing (don’t delete an operation from the system). Stale is a refresh. The Broken is a rebuild’d. Mix them up, and you’ll get the same incorrect number back on your re-roll in each of the first four quarters and figure you’d done something wrong – whereas you had. 

You type it in incorrectly, and you will receive the same wrong value each time you re-roll the first four quarters and shrug at that, believing the variance report is ripping you off; it isn’t. One way to see this is to look at the price change on those rates that you’re interested in; even if the gap looks ugly, it would be an indication of the method and not the price. This is where an experienced accounting partner earns their keep, because they’ve seen enough BOMs to tell the difference quickly instead of running the shop through another full cost study.

Decide How Often You’re Willing to Re-Roll Standards

The traditional manner of producing a yearly rollover, at the time of the budget, is based on the assumption that the inputs do not vary very rapidly, and that any changes which were made this year are not large enough to see in a yearly comparison. But that’s been dropped to the back of the queue and not come back around 2022.

One accounting-firm overview puts it plainly: failing to update standards to current conditions makes variance analysis irrelevant, and standards should be reviewed at least annually. Annually is the floor, not the target. The real decision is how much more often you can stand to re-roll without turning the finance team into a full-time standards shop. Most companies land in one of three places:

• Quarterly refresh: Actuals are used to update material rates, and labour rates are updated quarterly whilst overhead rates are updated once every two years or so. This really is the sweet spot to which most mid-size manufacturers can aspire.
• Annual chronogram: No calendar. When the value on the input exceeds a specified value, then all of the components that are in contact with the input component will be updated. In theory, it’s cleaner, less cumbersome, and it needs a system that’s able to monitor a trigger.
• Dual-track: To maintain the continuity of annual inventory value; disclose an annual inventory shadow current-cost view; but the standard practice of pricing, quoting, and margin review. Here, harder; no one’s mind occurs with a number sometimes.

Decide What the Standard Is For

Standard costing provides a consistent approach to assigning costs to inventory and comparing expected production costs with actual expenses. Variances are then documented when there is a discrepancy, and finance staff should review, identify, and properly document these variations. It’s very important to have the costs accurate when tracking utility bill costs; outdated knowledge can lead to a faulty or inaccurate budget. One of the most frequently seen reasons for costing errors is the pricing section. Compile the basic cost from routers, including some objective margins to produce quotes and sales teams. If the standard cost is not the actual cost, however, there are inconsistencies, or if the cost is no longer accurate, then if the result is a ‘one-day job’, it is sold at a loss; and only if the actual costs are checked several weeks later, upon discovering a difference between the standard and the real costs, will there be any deficiencies noted. 

Before now, select special decisions as well as those that have to be made using current cost. All price quotes, including review bids, make vs. buy, and capex payback calculations, should be done and based on the current cost. Variance is reported and inventory is valued as per the standards of S/N. The Cartesian coordinates can be used to graph inventory values and to indicate the difference in inventory between periods. The value of the inventory can be reported against a Cartesian coordinate system and plotted; the range of the inventory over the period of report may be displayed as a change of Cartesian coordinate.

Decide Who Owns the Number

In an unaccountable environment, the standards are moving fastest. Owned & managed roaming by Engg. Material rates are not a rate of HR but a rate of purchases; the same applies to labour rates. It is owned by Finance. When one of the four of them is silent, everybody thinks the other is keeping watch on the number on the router, and it continues getting older. Use one (and only one) owner for the standard cost process; set a cadence for that one owner; have the one owner auto-pull current rates from the other three to run the one on that cadence.

All part numbers must include a last updated date that is visible to anyone accessing the record. If that date is older than the latest contract with your biggest supplier, the displayed figures are likely incorrect. Manufacturing analytics can support finance teams in identifying discrepancies, and tracking these discrepancies between these figures can have a profound impact on budgeting, purchasing decisions, and financial reporting if the part costs are wrong.
