# Control Accounts in the Cost Ledger
## The Question
In a financial ledger, we maintain detailed accounts for each raw material, each work-in-progress job, and each finished product. But in the cost ledger, we use accounts named Raw Material Control A/c, WIP Control A/c, Finished Goods Control A/c, Wages Control A/c etc.
Why "Control"?
## The Reasoning
- When we say 'Raw Material A/c', it usually refers to ONE specific type of raw material (e.g., Steel A/c, Copper A/c).
- When we say 'Raw Material Control A/c', it refers to all types of raw materials taken together as a whole.
Similarly:
- WIP Control A/c = total of all jobs/processes in progress
- FG Control A/c = total of all finished goods
- Wages Control A/c = total wages payable / paid for all categories
## Why Use the "Control" Approach in the Cost Ledger?
1. Summary view for management — management is interested in total raw material consumed, not what each item cost.
2. Reduced volume of postings — instead of posting to 50 individual RM accounts, one Control A/c receives the aggregate.
3. Detailed records are kept in subsidiary records — bin cards, stores ledger, job-cost cards — outside the main control account.
4. Control function — the balance of the Control A/c should match the total of all subsidiary records. Any mismatch indicates an error → 'control' in the literal sense.
## Common Control Accounts in the Cost Ledger
| Control Account | What it captures |
|---|---|
| Raw Material Control A/c | All RM purchased, issued, returned |
| Wages Control A/c | All wages incurred (direct + indirect) |
| Direct Expenses Control A/c | All direct exp. incurred |
| Factory OH Control A/c | All factory indirect costs |
| Administrative OH Control A/c | All admin indirect costs |
| Selling & Distribution OH Control A/c | All S&D indirect costs |
| WIP Control A/c | All goods in process |
| Finished Goods Control A/c | All finished goods |
| Cost of Sales A/c | Final cost charged to revenue |
| Costing P/L A/c | Cost-profit summary |
| General Ledger Adjustment A/c | Substitute for debtors/creditors/cash in non-integrated system |
## Important Insight
In a non-integrated system, you'll find General Ledger Adjustment A/c instead of Cash/Bank/Debtors/Creditors — because the cost ledger does not 'see' those real-world parties; it only sees the totals coming in or going out.
