From the desk of Sudarshana — 25+ years in the jewellery industry
Every jewellery retailer wants to know the same thing at the end of a sale: did I make money on this transaction? The answer seems simple. Selling price minus cost equals profit. But in a gold jewellery business, "cost" is not a simple number — and choosing the wrong definition of cost leads to business decisions that look correct but are not.
I encountered this problem repeatedly across jewellery businesses I worked with. They were calculating profit margins — but using a definition of cost that gave them a misleading picture of their actual financial position.
Most jewellery billing systems calculate profit based on the current market gold rate at the time of sale. The logic seems sound: if gold is trading at Rs. 18,000 per gram today and you sell a 10-gram item for Rs. 210,000, your profit against current cost is Rs. 30,000.
This is the right basis for pricing decisions. When you set your selling price, you need to know whether you are competitive against the current market. If you priced based on what you paid for the gold three months ago, you might underprice in a rising gold market and lose the margin you should be capturing.
But here is the problem: If the gold in that item cost you Rs. 15,000 per gram when you purchased it six months ago, your actual profit on the transaction is Rs. 60,000 — double what the current-cost calculation shows. Conversely, if gold has fallen since you purchased, your actual profit may be significantly less than the current-cost calculation suggests. Using only current cost means you never know your real profit on any transaction.
The alternative is to calculate profit based on the historical purchase cost of the gold — what you actually paid for the raw material that went into each item. This gives you your true profit per transaction, because it reflects what the business actually spent to produce or acquire each piece.
But if you use historical purchase cost as the basis for your selling price, you have a different problem. In a rising gold market, you price items at what you paid for the gold, which may be well below current market rates. Customers — who know today's gold price — buy happily. You think you are making your target margin. In reality you are selling at below-market prices and cannot afford to replace the stock at current rates. In the long run, you erode your working capital without realising it.
| Scenario | Purchase Cost | Current Market | Selling Price | Profit (Current Cost) | Profit (Purchase Cost) |
|---|---|---|---|---|---|
| Gold price rose since purchase | Rs. 15,000/g | Rs. 18,000/g | Rs. 210,000 | Rs. 30,000 | Rs. 60,000 |
| Gold price same as purchase | Rs. 18,000/g | Rs. 18,000/g | Rs. 210,000 | Rs. 30,000 | Rs. 30,000 |
| Gold price fell since purchase | Rs. 20,000/g | Rs. 18,000/g | Rs. 210,000 | Rs. 30,000 | Rs. 10,000 |
10g item, making charge Rs. 10,000. Current-cost profit appears the same in all three scenarios. Purchase-cost profit shows the real picture.
The solution I implemented is straightforward once you frame the problem correctly. Neither figure is wrong — they answer different questions. The mistake is showing only one of them and treating it as the complete picture.
The implementation: Every sale transaction records two profit figures simultaneously — profit calculated against the current gold rate, and profit calculated against the actual purchase cost of the gold. Both figures are visible in the invoice, in the daily cash balancing report and in the management MIS.
Management sees the current-rate margin (for competitive pricing decisions) and the purchase-cost margin (for real profitability assessment) side by side. Neither replaces the other. Both inform different decisions.
Current-cost margin tells you whether your pricing is competitive. If your current-cost margin is thinner than your target, you are not capturing the full premium the market would support. This is your daily pricing signal.
Purchase-cost margin tells you whether the business is actually profitable. This is the figure that determines whether you can sustain operations, replace stock, pay staff and generate the return the business needs. This is your real financial health indicator.
When gold prices are rising, current-cost margin will appear lower than purchase-cost margin — a signal that you are capturing good profit on older stock. When gold prices are falling, current-cost margin will appear higher than purchase-cost margin — a warning that your real profit is below what the pricing suggests and stock replacement will cost you.
Before implementing dual-margin reporting, jewellery businesses I worked with were making pricing decisions based on current cost (reasonable) but assessing business health based on the same current-cost figure (misleading). When gold prices rose over an extended period, current-cost margins looked thinner than historical norms. Management read this as a profitability problem and began cutting costs, reducing stock, discounting to move inventory. In reality, their purchase-cost margins were excellent because they had purchased gold at lower prices. They were solving a problem that did not exist.
After implementing dual-margin reporting, the same business could see immediately that while current-cost margins were thinner, purchase-cost margins were strong. Pricing decisions and operational decisions were separated. Each was made with the right information.
Management could distinguish between a genuine profitability problem and a gold price movement effect for the first time. These had previously been invisible to each other.
Pricing decisions were made against current market rates without confusion about whether current-cost margins reflected real business health.
In falling gold markets, the purchase-cost margin provided early warning that real profitability was under pressure before the current-cost figure showed it clearly.
Stock purchasing decisions improved. Understanding the true purchase-cost margin on current inventory helped management make better decisions about when and how much gold to purchase.
Jwellex records the purchase cost of gold at the point of entry — whether from a raw material purchase, a manufacturing process or a supplier invoice. When an item is sold, the system calculates and displays both the current-rate margin and the purchase-cost margin on every transaction.
Both figures appear in daily balancing reports, in the management MIS and in periodic profitability analysis. Neither is hidden. Neither is presented as the "correct" figure to the exclusion of the other. Management sees both and uses each for its proper purpose.
