How this calculation works
An Indian eight-gram unit converts to gross grams before any value calculation. A quote for that same purity multiplies gross grams directly; a pure-gold quote uses fine-gold equivalent grams. Purity is applied once, not again to a quote that already prices the chosen fineness.
Total = (quote × quoted-basis grams + making charge × gross grams) × (1+entered tax/100)A worked example
One eight-gram unit at an entered same-purity quote of ₹6,000 per gram costs ₹48,000 before any entered charges. At 916 fineness, its fine-gold equivalent is 7.328 grams.
Good to know
No live price or tax classification. The eight-gram Indian trade convention differs from the British sovereign coin. Enter fineness rather than assuming every 22-carat article is exactly 22/24 pure. Stones, wastage, fixed fees and buyback deductions are excluded.

Name the eight-gram unit explicitly
In the Indian gold-trade convention used here, one unit is exactly eight grams. Tamil Nadu’s statistical handbook describes a sovereign as eight grams in its scheme tables. The page keeps that weight convention separate from the specifications of a British sovereign coin.
Names such as pavan or savaran may be used conversationally, but the calculation depends on the stated eight-gram weight. Confirm the invoice’s gross gold weight and whether stones or non-gold components have been excluded.
The mass converter can check gram-based quantities, while this gold weight and price calculator adds an explicitly entered fineness and quote basis.
Avoid applying purity twice
Suppose the entered quote is ₹6,000 for one gram at the selected 916 fineness. Eight gross grams then have a modeled metal value of ₹48,000. Multiplying that result by 0.916 again would discount a quote that already prices that purity.
If the quote instead prices one gram of pure gold equivalent, eight grams at 916 fineness represent 7.328 fine-gold grams. The pure-gold quote multiplies that smaller fine-gold amount. The quote-basis option makes the distinction visible.
Keep an estimate separate from a shop invoice
Making charge is modeled here as an entered rupee amount per gross gram. The optional illustrative tax input applies to metal value plus that making amount. Neither the percentage nor that base is selected as a legal tax classification.
A real invoice may include stones, wastage, fixed labour charges, discounts or other items. Entering a live market price is your choice; the calculator does not fetch one. The percentage calculator can inspect an individual stated charge, while this page combines the explicitly entered components.
A few questions, answered
Is this a live gold-rate page?
No. Every price and percentage comes from your inputs, making the estimate reproducible without a price feed.
Is 916 exactly the same as 22 divided by 24?
No. This tool uses the entered parts-per-thousand fineness directly. For 916, the multiplier is 0.916 rather than the mathematical fraction 22/24.
Does a British sovereign coin weigh eight grams here?
The eight-gram option is the explicitly named Indian trade unit. Do not use it as a specification for a particular coin. Enter that item’s measured grams instead.
