Searching for an old gold exchange calculator, jewellery exchange calculator, or gold buyback calculator? Indians commonly part-exchange hallmarked or scrap jewellery when buying a new piece. The counter values net gold weight at today's rate, deducts melting or refining, then applies an exchange credit to a new invoice that includes making charges and GST.
This free Nelstack tool estimates how many new grams you can get, how much cash you still pay, and how exchange compares with selling for buyback cash and buying new separately — before you walk into the store.
Jewellers and online old-gold valuation tools share the same core formula:
Gross old value = net gold grams × rate per gram for that purity (22K / 18K / 24K).
Exchange credit ≈ gross old value − melting / refining (% and/or flat fee). Optionally replace the formula with the quoted credit printed on the shop estimate.
New jewellery invoice = new gold value + making charges + GST on gold (and optionally GST on making). Cash due = invoice − exchange credit. Negative cash due means unused credit or a refund-style surplus on paper — confirm how your jeweller treats it.
Worked example (22K): 40 g at ₹7,000/g with 3% melting → ≈ ₹2,71,600 credit. Matching new rates, 12% making, 3% GST on gold (making GST off), zero top-up → roughly 33.7 g of new gold. Change rates to match today's gold rate in India.
| Feature | Exchange gold | Sell old, buy new | Buy new gold |
|---|---|---|---|
| Old gold treatment | Credit against new invoice (typical 1–5% melting) | Cash/proceeds at higher deduction (often ~5–8%+) | No old gold; pay full invoice |
| Making on old piece | Usually not recovered | Usually not recovered | N/A |
| When it can win | Lower deduction + GST/value-addition rules favour you | Rarely cheaper than exchange for the same shop | When you have no old gold or need a different purity |
| Typical search intent | Old gold exchange / jewellery exchange calculator | Gold buyback / sell old gold calculator | Jewellery cost with making + GST |
Chain offers (sometimes marketed as low or zero deduction) vary by brand and campaign. Set melting to 0% or paste a quoted credit if your store publishes a special exchange rate — this calculator is brand-agnostic and not affiliated with any jeweller.
Making charges on the old piece are almost never recovered on exchange or buyback. New jewellery usually adds fresh making (% of gold, ₹ per gram, or flat).
Stones and non-gold weight should be subtracted so only net gold is valued. Ask for stones to be returned and for weighing/testing in your presence (Karatmeter / XRF).
BIS hallmark (for example 916 for 22K) can improve trust in purity but does not replace a shop test. For GST, many invoices use about 3% on gold and 5% on making when itemised; practices differ between full-bill and value-addition treatment — use the Tax section to match what your counter explains.
Anyone upgrading bangles, chains or sets; comparing a local jeweller quote with a national chain; checking whether cash buyback then repurchase is worse than exchange; or estimating cash top-up before a wedding or festival purchase. Pair it with the jewellery cost estimator on our gold rates page for a full buy-side view.
An old gold exchange calculator estimates how much credit you may get when swapping old jewellery for new gold. It multiplies net gold weight by today’s rate, subtracts melting/refining, then compares that credit with the new bill (gold + making + GST) so you can see grams you can buy or cash you still pay.
1) Weigh gross grams. 2) Subtract stones/non-gold weight → net gold. 3) Multiply by the purity rate (22K/18K/24K) you and the jeweller agree. 4) Subtract melting/refining % or flat fee. 5) Apply that exchange credit to the new jewellery invoice. This page’s calculator follows the same flow and lets you override with a shop-quoted credit.
Exchange usually offers a better effective rate than cash buyback at the same counter because the jeweller wants you to buy new stock. Buyback (sell for cash) often applies a higher deduction. Use Compare mode: Exchange gold vs Sell old, buy new vs Buy new gold to see cash-out differences for the same new weight.
Counters cite melting, refining and purity uncertainty — commonly about 1–5% of old gold value on exchange (often higher on pure cash buyback). Hallmarked BIS pieces may get a cleaner quote, but shops still test with a Karatmeter/XRF. Enter the % or flat fee your jeweller quotes, or paste their quoted credit.
Almost never. Making charges paid when you bought the piece are sunk cost. Exchange and buyback are based on recoverable gold content (weight × purity × rate), not the original invoice total. New jewellery will usually add fresh making charges again.
On the new piece, jewellers commonly charge about 3% GST on gold value and 5% on making when itemised. Some invoices tax the full new bill; others talk about GST mainly on value addition after credit. This calculator lets you set GST on gold, optionally add GST on making, and toggle full-bill vs value-addition treatment.
It depends on melting deduction, making on the new piece and GST. Example: 40 g of 22K at ₹7,000/g with 3% melting → ≈ ₹2,71,600 credit. With matching new rates, 12% making and 3% GST on gold (making GST off), zero top-up → roughly 33.7 g of new gold. Edit rates to match today’s ticket.
Related but not identical. A buyback/resale calculator estimates cash for selling old gold. An exchange calculator also models the new jewellery side (making + GST) and net cash or grams after credit. Nelstack covers both paths in one tool with Compare mode.
Brand schemes change and are marketing policies, not universal maths. If your store advertises 0% melting, set deduction to 0% or enter their quoted credit. This tool is brand-agnostic and illustrative — not affiliated with any jeweller chain.
Only the gold portion is valued for exchange/buyback. Enter non-gold weight (stones, beads, etc.) so net gold = gross − non-gold. Ask the jeweller to return stones separately and weigh gold in front of you.
Hallmarking (e.g. 916 for 22K) builds trust in purity and can improve the quote, but shops still verify. Unhallmarked or scrap pieces may face a higher wastage/purity haircut. Use the purity and credit your counter confirms.
‘Old gold rate today’ searches usually mean today’s market rate applied to used jewellery — there is no separate official IBJA ‘old gold’ fixing. Your cash or exchange credit is market rate × net weight × purity, then deductions. Live prefills here are indicative retail references; edit them to the rate printed on your estimate.
No. It is an educational estimator for India. Actual offers depend on purity tests, deductions, invoice GST practice and store policy. Not tax, legal or investment advice. Always get a written line-item breakdown before you exchange.
