When you want to understand what old jewellery might be worth, it helps to begin with a neutral reference: how much gold content the item represents based on its weight and stated purity. That number is useful for comparison, but it is not automatically the amount a buyer will pay.
Estimate first, quote second
An online calculation can provide an indicative gold-content value. A resale quote requires a buyer's assessment of the actual item.
The three inputs behind theoretical old-gold value
Weight
The weight used in the calculation determines how much material is being valued.
Purity
The stated karat determines the pure-gold proportion used in the estimate.
Reference rate
A reference gold rate provides the monetary basis for the gold-content estimate.
If you need a refresher on how karat affects the pure-gold proportion, read the Gold Purity guide.
Why an actual resale quote can differ
The item's physical purity may be assessed rather than assumed from an online input.
The eligible weight used by a buyer can differ from the gross weight entered in a calculator.
A buyer can use a different gold-rate methodology from the informational reference rate.
Explicit deductions or other commercial terms can reduce the amount offered.
Separating theoretical value from a deduction
Assume a hypothetical theoretical gold-content value of ₹1,00,000.
If you want to model an explicitly quoted deduction of ₹2,000:
₹1,00,000 − ₹2,000 = ₹98,000.
The ₹2,000 figure is only an example. Gold Ledger does not assume that a standard deduction applies to every old-gold transaction.
Why deductions should remain explicit
Hiding a deduction inside the calculation makes it harder to understand why the estimated amount changed. Gold Ledger keeps the deduction as a separate input so you can compare the theoretical gold-content value with the amount remaining after the deduction you entered.
This does not imply that a particular deduction is appropriate. It simply makes the mathematical effect of an entered deduction visible.
What an online calculator cannot determine
Whether the stated purity matches the item's actual physical purity.
Whether the full gross weight will be treated as eligible gold by a buyer.
What rate a particular buyer will use when making an offer.
What final amount a jeweller or gold buyer will quote after inspecting the item.

Frequently asked questions
How is the theoretical value of old gold estimated?
A basic estimate can use the item's weight, stated purity and a reference gold rate to calculate its theoretical gold-content value.
Why can an old-gold buyer offer less than the calculated gold-content value?
An actual buyer may use its own physical purity assessment, measured eligible weight, deductions, rate methodology and commercial terms. Those factors can make a quote differ from an informational estimate.
Is there one standard deduction for selling old gold?
Gold Ledger does not assume that one deduction applies universally. If a deduction is relevant to a comparison, it should be entered explicitly so its effect remains visible.
Can an online calculator verify the purity of old jewellery?
No. A calculator can estimate value from a purity input, but it cannot physically test an item, verify a hallmark or determine the purity a buyer will assess.
