Standard costing that surfaces the variance
Value production at a standard cost, book the difference between standard and actual to dedicated variance accounts, and see exactly where the factory drifted from plan.

Standard costing vs actual costing
Actual costing values every unit at what it actually cost to make - precise but volatile and slow. Standard costing values units at a predetermined standard, then measures the difference from actual as a variance. Standards make production costing fast and comparable; variances tell you where reality diverged so you can act.
| Approach | Strength | Trade-off |
|---|---|---|
| Actual costing | Exact unit cost | Volatile, hard to plan against |
| Standard costing | Fast, comparable, plan-friendly | Needs variances to explain the gap |
How Fintra books standard cost
When a work order for a standard-cost item completes, Fintra books finished goods at the standard cost times the quantity and posts the residual WIP - the difference between accumulated actual cost and standard - to a production variance account. Standard-cost items therefore always relieve WIP cleanly to a known finished-goods value.
Production variance on completion
production_variance = accumulated_WIP − (standard_cost × qty_completed)
A positive residual is unfavourable (actual exceeded standard); a negative residual is favourable. It posts to the production variance account (5045).
Dedicated variance accounts
- A production variance account (5045) captures the WIP-to-FG residual on completion.
- Material price, material usage, labor rate, labor efficiency, and overhead each have their own account (5040–5044).
- The variance report sums posted activity in these accounts and labels it favourable or unfavourable.
Why manufacturers run standards
Standards turn a noisy stream of actual costs into a stable plan you can price and budget against, while variances give you a monthly scorecard of where the factory beat or missed that plan. That combination - stable costing plus a variance signal - is why standard costing is the backbone of most manufacturing accounting.
Frequently asked questions
What is the difference between standard and actual costing?
Actual costing values products at their real incurred cost, which is precise but volatile. Standard costing values them at a predetermined standard and books the difference from actual as variances. Standards make costing fast and comparable, while variances explain where actual diverged from plan.
How does Fintra book standard cost on a work order?
When a standard-cost work order completes, finished goods are booked at standard cost times the quantity completed, and the residual WIP - accumulated actual cost minus that standard value - posts to a production variance account. So finished goods always carry a known standard value.
What is a production variance?
A production variance is the difference between the actual cost accumulated in WIP and the standard cost of the units completed. A positive residual is unfavourable (actual exceeded standard); a negative residual is favourable. Fintra posts it to a dedicated production variance account on completion.
Where does the standard cost come from?
The standard cost lives on the inventory item and typically comes from the BOM roll-up of material, labor, and overhead. Movements for standard-cost items are valued at that standard, so drift from actual shows up as a variance instead of a shifting unit cost.
