Making Charges, Wastage & GST: How to Configure Jewellery Pricing Formulas in WooCommerce
Introduction
The price of a gold jewellery item is never just the weight of metal multiplied by today’s rate. Every piece you sell carries additional costs — the craftsmanship that shaped it, the metal lost during manufacturing, and in markets like India, the applicable tax. Getting these components right in your WooCommerce store isn’t just a technical task — it’s the difference between accurate profitability and systematic margin erosion.
This article explains each component of the jewellery pricing formula, how it works in the real world, and exactly how to configure it in WooCommerce using the ITS Jewellery Price Plugin.
Understanding the Full Jewellery Pricing Formula
Before touching any settings, it’s worth understanding the formula your pricing should implement: code Codedownloadcontent_copyexpand_less
Product Price = Metal Value + Making Charge + Wastage Charge [+ GST]Where:
- Metal Value = Metal Weight (grams) × Metal Rate (per gram)
- Making Charge = Fixed per gram OR percentage of metal value
- Wastage Charge = Percentage of metal value (or metal weight × rate × wastage %)
- GST = Applied to (Metal Value + Making Charge + Wastage) at the applicable rate
Let’s break each component down in detail.
Making Charges: What They Are and How to Set Them
What Is a Making Charge?
Making charge is the fee a jeweller charges for the skilled labour involved in creating a jewellery piece. It covers:
- The artisan’s time and skill
- Workshop overhead (tools, equipment, electricity)
- The jeweller’s margin on craftsmanship
- Design complexity (more intricate pieces command higher making charges)
Making charges vary enormously. A simple gold chain might carry a making charge of ₹150–₹300 per gram. A hand-crafted bridal necklace with detailed filigree work might command ₹800–₹1,500 per gram. Chains are typically on the lower end; heavily worked bangles, kundan sets, and bridal jewellery are on the higher end.
The Two Ways to Express Making Charges
Method 1: Flat charge per gram
This is simpler to understand and communicate. If the making charge is ₹350/gram and the item is 15 grams, the making charge is ₹350 × 15 = ₹5,250, regardless of what gold is doing that day.
This method is common for items where craftsmanship cost scales directly with weight — chains, plain bangles, simple rings.
Method 2: Percentage of metal value
Here the making charge is calculated as a percentage of the current metal value. If making charge is 12% and the metal value is ₹92,700, the making charge is ₹92,700 × 12% = ₹11,124.
This method means your making charge income scales with the gold price — if gold goes up, your making charge revenue goes up proportionally. It’s common for designs where the gold content is more significant than the labour in total cost.
Neither method is universally better. Use the one that matches how your manufacturer or workshop bills you, or the one that gives you the margins you need on each product type.
Configuring Making Charges in the ITS Plugin
When you edit a product and open the Jewellery Price tab, you’ll find the Making Charge field with an option to select the type (flat per gram or percentage).
For flat per gram: Enter the per-gram making charge amount. For a necklace with a ₹350/gram making charge, enter 350. The plugin multiplies this by the product’s metal weight.
For percentage: Enter the percentage value. For a 12% making charge, enter 12. The plugin calculates the metal value first (weight × rate) and applies the percentage to that.
Because making charges are product-specific — not metal-rate-specific — you enter them once per product and they stay fixed. Only the metal rate changes daily. The making charge amount in rupees will change if you’re using the percentage method (because it’s calculated against the metal value), but the percentage itself is stable.
Wastage Charges: The Hidden Cost of Craftsmanship
What Is Wastage?
Wastage (also called “scrap” or “loss” in some jewellery markets) refers to the precious metal lost during the manufacturing process. It’s a real and unavoidable cost of jewellery production.
When a goldsmith works with gold, small amounts are lost through:
- Metal filings from shaping and finishing
- Small pieces lost during soldering
- Polishing loss
- Rejects and rework
Wastage is typically expressed as a percentage of the metal weight or metal value, and it ranges from roughly 2% for simple cast pieces to 8–12% for heavily hand-worked jewellery.
Is Wastage Separate From Making Charge?
Yes, and understanding why matters for pricing correctly. Making charge is the cost of labour. Wastage is the cost of lost material. They’re separate items:
- If there’s no wastage (theoretically possible for machine-made cast jewellery), the making charge still applies
- If there are additional wastage charges (high for handmade pieces), they’re added on top of making charge
In practice, some jewellers bundle these together, but keeping them separate makes your pricing more transparent and easier to adjust independently.
Configuring Wastage in the ITS Plugin
In the Jewellery Price product tab, the Wastage Charge field accepts a percentage value. Enter the wastage percentage for that specific product — for example, enter “5” for 5% wastage.
The plugin calculates the wastage amount based on the metal value (weight × rate × wastage%). This means wastage charges, like percentage-based making charges, scale with the gold price.
Setting wastage by product category:
Rather than setting wastage arbitrarily, align it with what you actually pay your manufacturer. Common benchmarks:
- Machine-made chains: 2–3%
- Cast rings and pendants: 3–5%
- Hand-crafted bangles: 5–7%
- Filigree and kundan work: 8–12%
If your manufacturer charges 5% wastage on a particular product, use 5%. Don’t under-report wastage or you’ll be absorbing the cost yourself.
GST on Gold Jewellery: The Indian Context
How GST Applies to Jewellery
For jewellery retailers in India, GST adds a layer of complexity to product pricing. The current GST structure for gold jewellery is:
- 3% GST on gold (whether it’s a gold bar, coin, or jewellery)
- 5% GST on making charges (the labour component is treated differently from the metal)
This means the effective GST on a gold jewellery item is not a flat 3% on the total price — it’s 3% on the metal+wastage component and 5% on the making charge component.
In practice, many jewellers in India display an “inclusive” price (GST already included) rather than adding it separately at checkout. Some display ex-GST and add it at checkout. Both are legitimate; the important thing is consistency and correct calculation.
Configuring GST in WooCommerce
GST in WooCommerce is handled through the built-in Tax system, not through the jewellery pricing plugin. The plugin calculates the pre-tax price (metal + making + wastage), and WooCommerce’s tax engine applies the applicable rate on top.
Setting up GST in WooCommerce:
- Go to WooCommerce → Settings → Tax
- Enable taxes if not already enabled
- Go to the Standard Rates tab and add a tax rate:
- Country: India (IN)
- Rate: 3%
- Tax name: GST
- Select whether this is inclusive or exclusive
For the nuanced GST structure (3% on metal, 5% on making), proper implementation requires either:
- A tax plugin that supports component-based GST (like WooCommerce Tax or a GST-specific plugin)
- Setting a blended approximate rate based on your typical product composition
- Consulting with your CA for the configuration that aligns with your tax filing
The ITS Jewellery Price Plugin handles the pre-tax price calculation. Tax is applied by WooCommerce on top. The two systems work together without conflict.
GST for Non-Indian Stores
If you’re running a jewellery store in the UAE, UK, Australia, or elsewhere, your applicable tax rate and rules differ:
- UAE: VAT at 5% on jewellery (with certain exemptions for pure gold investment products above 99% purity)
- UK: VAT at 20% on jewellery (jewellery is a luxury good; standard VAT rate applies)
- Australia: GST at 10% on all jewellery
- USA: Sales tax varies by state; use a WooCommerce sales tax plugin or Avalara/TaxJar integration
Configure your applicable tax in WooCommerce’s Tax settings. The pricing plugin handles the jewellery formula; WooCommerce handles the tax.
Putting It All Together: A Worked Example
Let’s trace a complete price calculation for a 22K gold bangle:
Product details:
- Metal: 22K gold
- Metal weight: 18 grams
- Today’s 22K gold rate: ₹6,200/gram
- Making charge: ₹400/gram (flat)
- Wastage: 6%
Calculation:
| Component | Calculation | Amount |
| Metal Value | 18g × ₹6,200 | ₹1,11,600 |
| Making Charge | 18g × ₹400 | ₹7,200 |
| Wastage Charge | ₹1,11,600 × 6% | ₹6,696 |
| Pre-GST Total | ₹1,25,496 | |
| GST (3% on metal+wastage, 5% on making) | (₹1,18,296 × 3%) + (₹7,200 × 5%) | ₹3,549 + ₹360 = ₹3,909 |
| Final Price | ₹1,29,405 |
In the ITS plugin, you’d configure:
- Metal: Gold 22K (rate: ₹6,200/gram — updated daily)
- Metal Weight: 18
- Making Charge: 400 (flat per gram)
- Wastage: 6 (percentage)
The plugin calculates the pre-GST price (₹1,25,496) automatically. WooCommerce adds the GST at checkout or displays it inclusive, depending on your tax configuration.
Tomorrow, if gold rises to ₹6,350/gram, the metal value becomes ₹1,14,300, wastage becomes ₹6,858, and the pre-GST total updates to ₹1,28,358 — automatically, without you touching the product.
Common Configuration Mistakes to Avoid
Mixing flat and percentage making charges inconsistently. Choose one method per product type and be consistent. If your chain supplier bills by flat per gram and your bangle manufacturer bills by percentage, configure each product type accordingly — but don’t mix methods within the same category.
Using the wrong weight field. The metal weight field should contain the net metal weight — the weight of the precious metal content of the item. This is different from the total product weight (which includes stones, clasps, and other non-metal components). Using total product weight will over-calculate the metal value and price your products too high.
Setting making charges too low to recover costs. When setting making charges in your plugin configuration, verify they actually cover what you pay your manufacturer plus your own markup. A common error is entering the manufacturer’s making charge without adding your own margin on the craftsmanship component.
Ignoring wastage on machine-made products. Even machine-made cast jewellery has some wastage (typically 2–3%). Not accounting for it means you’re absorbing this cost silently. Set at least 2% wastage even on your simplest products.
Not testing after a rate update. After you first configure your metals and products, update the gold rate by a test amount and verify that prices change correctly on the front end. This takes 5 minutes and confirms everything is wired up correctly.
A Note on Transparency With Customers
One of the philosophically important aspects of displaying the full pricing formula — metal value, making charge, wastage — is that it invites scrutiny. Some jewellers are hesitant to show this breakdown because they worry customers will question the charges.
In practice, the opposite tends to be true. Customers who see the breakdown understand that making charges are a real cost of skilled craftsmanship, not an arbitrary markup. They understand that wastage is a real material loss, not a hidden fee. The transparency builds confidence, not scepticism.
The stores most afraid to show the formula are often the ones with the most reason to be — stores padding margins in opaque ways. If your pricing is honest and competitive, showing the formula is entirely in your interest.
Conclusion
Configuring making charges, wastage, and tax correctly in your WooCommerce jewellery store is a one-time setup task that protects your margins and enables full pricing transparency. The ITS Jewellery Price Plugin handles the formula mechanics; WooCommerce handles the tax. Together they give you an automated pricing system that reflects exactly how jewellery is priced and sold in the real world.
Get the setup right once, and every future price update — just changing the daily gold rate — cascades through the entire formula correctly for every product.
