Standard costing and variance analysis: how do you find out exactly where your factory is losing money?
I set a standard cost for every product in my factory, but the actual numbers at month-end never quite match — what does that mean, and what should I do about it?
Standard costing means fixing, in advance, what a single unit of product should cost to make — based on an expected quantity and price for materials, labour, and manufacturing overhead. When you close the month and compare actual cost to that standard, the difference is called a variance. A variance isn't a number to assign blame over — it's a diagnostic tool that points to exactly where something went off plan.
The first category is the material variance, which splits into two parts: a price variance (you paid more or less per unit of material than planned, whether from a new supplier, inflation, or better negotiation) and a usage variance (you consumed more or less material than the standard allows for the same output, usually from production waste or an efficiency gain). As an illustrative example: if the standard is 2kg of material per unit at AED 10/kg, and you actually used 2.3kg at AED 11/kg, the variance is a combination of a price increase and higher-than-planned consumption.
Labour variance works the same way: a rate variance (the actual hourly wage differs from standard, often due to overtime or a different skill mix on the line) and an efficiency variance (actual hours used are more or less than standard for the same output, reflecting real productivity on the floor).
Overhead splits into a spending variance (the difference between what was actually spent on items like maintenance and utilities and what was budgeted) and a volume variance (the effect of producing a different quantity than the level the original standard was built on, which changes how fixed costs get spread across units). Taken together, these variances give a factory owner a precise picture of where a margin slipped, instead of simply noticing profit dropped without knowing why — the kind of analysis RASEEKH helps industrial clients build once their books are organised and reviewed on a regular basis.
