You put in your gold’s weight and purity into a sell gold calculator , and it spits out a number that looks like it’s been settled. Then a buyer tests, weighs and quotes, and the number drops. That does not mean you are always being short-changed. A calculator is based on assumptions, and every assumption has a margin. Knowing where those margins are gives you an idea of whether a lower offer is fair or badly explained.

Where the difference comes from

Most of the gap sits in five places. Here is what the calculator assumes against what can change at the counter.

Factor	What the calculator assumes	What can change
Purity	The hallmark or carat you entered	Old pieces, repairs and mixed alloys can test lower
Weight	Gross weight on the bill	Stones, lac, enamel and clasps are not gold
Rate	One price at one moment	Rates move through the day
Melting loss	Nil	Some loss if the process is careless
Making charges	Value of the piece as jewellery	Buyers often pay only for the gold content

Purity and weight cause the biggest swings because they change how much pure gold you are actually selling. A 20 g necklace entered as 22kt holds about 18.3 g of pure gold. If it tests at 21kt and has 0.8 g of stones, the pure gold falls to about 16.8 g, a drop of more than 1.5 g before any rate is applied.

Why two buyers can quote different amounts

Not all buyers are alike. A jeweller taking old gold against a new purchase may credit the value against the exchange. A local dealer might do a quick but rough test with a touchstone. A dedicated gold buyer may test with an XRF machine. None of these is wrong in itself, but the method determines how much of the gold’s real value you receive.

How to tell whether an offer is fair

Work backwards. Ask the buyer what tested purity, what net weight and what rate he used and then multiply them yourself. The gap is explained if the result is as good as or better than the offer. If it doesn't, then there is something else being deducted, and you have a right to know what.

Steps that protect your final value

Weigh the piece yourself and subtract stones you can see.
Run a sell gold calculator with purity one carat lower and treat the answer as a range, not a promise.
Compare the rate on offer with a live market rate on the same day.
Ask whether testing is done in front of you and whether it damages the piece.
Get a proper invoice and a clear payment timeline.

If you bought the gold as an investment, calculate your gold investment returns on the amount that lands in your bank, not on the screen figure. That is the number that counts.

Mistakes that widen the gap

Entering the carat stamped on the piece without allowing for old repairs.
Selling on the first quote without a second opinion.
Taking a verbal figure instead of a written one.

What a transparent sell gold process looks like

Transparency is key in a gold sale because most of it is hard to verify yourself. Purity, melting loss, and weight are taken on faith unless the process is open. A transparent sale lays out the controls for you: purity tested right before your eyes, a process that does not cause metal loss, a rate that keeps up with the live market, and an invoice for every step. If any is absent, ask why.

myGold’s sell gold service is built around these checks. Pricing is linked to live market rates. Jewellery is tested with XRF, which is non-destructive. The gold is melted in high-quality crucibles that are designed to prevent metal loss, and tested again for purity. Treated with ultrasonic cleaning and weighed with an accuracy of 0.001 g. Payment is by instant bank transfer(IMPS/NEFT/RTGS), with a proper invoice, and all jewellery is accepted, BIS hallmarked or not.

Before you sell, try myGold’s sell gold calculator first. Treat that figure as a range, then let the tested result confirm it.

Conclusion

The reliability of a quote is only as good as the purity and weight behind it. You can use a sell gold calculator to establish a realistic range and check the rate, ask for a written breakdown and allow a proper test to confirm the rest.
