What it means
When running a business, you usually budget a specific amount for the raw materials needed to create your products. Sometimes, suppliers change their prices, or you have to buy from a different vendor at short notice.
Material price variance is the financial measurement of the difference between what you expected to pay and what you actually paid for those supplies. This metric matters because it directly impacts your profit margins.
If your purchasing team manages to negotiate lower prices, your material price variance is favourable, meaning you saved money. Conversely, if market prices spike or supply chain issues force you to pay premium rates, you experience an unfavourable variance that eats into your bottom line.
In daily operations, finance teams calculate this variance for every batch of materials purchased. By reviewing these figures regularly, managers can spot troubling supplier price increases early, negotiate better long-term contracts, or decide when it is time to look for alternative vendors.
Tracking this metric also keeps purchasing teams accountable. It separates the cost of the raw materials from the amount of materials used, ensuring you know exactly why your production costs went up or down during a specific reporting period.
Imagine budgeting $10 for a taxi ride to work, but heavy traffic forces the driver to take a longer route, and the meter reads $12 at the end of the trip. That extra $2 is your price variance.
In practice
Real-world examples
Example 1
As a boutique coffee roaster, you budgeted $5 per kilogram for green beans. Due to a poor harvest, you actually paid $6 per kilogram for 1,000 kilograms, creating a $1,000 unfavourable variance (a $1 overspend on each kilogram).
Example 2
A small furniture maker budgeted $30 per sheet of plywood. Your purchasing manager negotiated a bulk deal of $25 per sheet for 200 sheets, resulting in a $1,000 favourable variance, although the manager should check that quality has not slipped.
Example 3
A mid-sized bakery budgeted $2 per kilogram for flour. Because of urgent delivery needs, you bought from a local supplier at $2.50 for 500 kilograms, producing a $250 unfavourable variance that came from paying for speed.
Think of it
Imagine budgeting ten pounds for a taxi ride to work, but heavy traffic forces the driver to take a longer route, and the meter reads twelve pounds at the end of the trip. That extra two pounds is your price variance.
Formula
Calculation
Material Price Variance = (Standard Price - Actual Price) x Actual Quantity Purchased. A negative result is unfavourable (you paid more than planned) and a positive result is favourable. For example, if your standard price was $10 per unit, your actual purchase price was $12, and you bought 500 units, the calculation is ($10 - $12) x 500 = -$1,000. This is a $1,000 unfavourable variance.
Now reverse it. If the actual price had been $9 for the same 500 units, the calculation would be ($10 - $9) x 500 = +$500, a $500 favourable variance. Note that the formula multiplies by the quantity actually purchased, not the quantity used, which is what keeps price and usage variances separate.Case study
Seen in the real world
This is a fictional, illustrative scenario. GreenLeaf Cosmetics manufactures organic skin care products. For their flagship moisturiser, the company budgeted a standard cost of $4 per bottle for organic shea butter. At the end of the month, production records showed the company purchased 2,000 bottles worth of shea butter, but the actual invoice averaged $4.50 per bottle due to rising global demand for organic ingredients.
The finance manager calculated the material price variance by taking the standard price of $4, subtracting the actual price of $4.50, and multiplying the result by the actual quantity of 2,000 bottles purchased. This produced a $1,000 unfavourable variance. Armed with this data, the operations director met with the procurement team. They reviewed the supplier contracts and discovered that buying in larger quarterly batches could lock in the original $4 rate.
GreenLeaf adjusted its purchasing strategy the following month, eliminating the variance and protecting their profit margins. Over a full year at the same volume, the extra $0.50 per bottle would have cost $12,000 if purchases ran at 2,000 bottles a month, so the saving from the new purchasing approach was significant. The team also agreed to review standard prices each quarter. If the market price of shea butter stayed higher than $4, the standard itself would need to move to a more realistic figure, otherwise every future report would show a variance that no one could control.
Watch out
Common mistakes
- Failing to separate the price variance from the usage variance.
- Using outdated standard costs that do not reflect current market realities.
- Blaming the production team for extra costs caused by purchasing decisions.
Questions
People also ask
Who is responsible for material price variance?
Usually, the purchasing or procurement manager is held accountable because they negotiate supplier contracts and buy the materials.
Is a favourable variance always a good thing?
Not always. If you paid a lower price by buying inferior quality materials, it might lead to higher waste and unhappy customers.
How often should I calculate this variance?
Most businesses calculate material price variance monthly as part of their standard management accounts review.
