Two people can walk into the same lender with seemingly similar jewellery and walk out with very different loan amounts. A gold loan calculator will show you why. Its result depends on several inputs and assumptions, and a small change in any of them can shift your figure by tens of thousands of rupees. This guide walks through each factor that affects the result, with a worked base case so you can see how much each one matters. The prices and slabs are illustrative, based on recent descriptions of India’s 2026 gold-lending framework, so confirm the current figures with your lender.
The Base Case
Suppose you have a 22-carat necklace weighing 30 grams in total, including 4 grams of stones. Using an illustrative 24-carat price of ₹15,000 per gram:
- Net gold weight: 30 − 4 = 26 grams
- Gold value: 26 × (22 ÷ 24) × 15,000 = ₹3,57,500
- Loan at 80% LTV: about ₹2,86,000
Now let’s see how each factor changes this.
1. Net Weight vs. Gross Weight
This is the most common source of overestimates. Lenders value only the gold content, so stones, pearls, enamel, and other materials are deducted.
- Using the gross weight of 30 grams by mistake gives a value of ₹4,12,500 and a loan of about ₹3,30,000
- The correct net weight of 26 grams gives about ₹2,86,000
That’s an overestimate of roughly ₹44,000. Weigh your jewellery carefully and subtract non-gold parts, or ask the jeweller or lender for the net weight.
2. Gold Purity
Purity is converted into a factor: 24 carat is 1.000, 22 carat about 0.916, 20 carat about 0.833, and 18 carat 0.750.
- 22 carat (base case): value ₹3,57,500, loan about ₹2,86,000
- 24 carat, same net weight: value ₹3,90,000, loan about ₹3,12,000
- 18 carat, same net weight: value ₹2,92,500, loan about ₹2,48,625
Check the hallmark rather than guessing, since a lender’s testing decides the final purity. Many lenders also accept only gold above a minimum purity, so very low-carat items may not qualify.
3. The Gold Price Used
Calculators and lenders value your gold using a reference price per gram, and the figure changes daily.
- At ₹13,500 (10% lower), value falls to ₹3,21,750 and the loan to about ₹2,57,400
- At ₹15,000, the loan is about ₹2,86,000
- At ₹16,500 (10% higher), value rises to ₹3,93,250 and the loan to about ₹3,14,600
Be aware that lenders may use a benchmark price that differs slightly from the retail rate you see in a jeweller’s shop, and the 24-carat versus 22-carat reference can differ between calculators. Use the same price basis when comparing tools.
4. The Loan-to-Value Ratio
The LTV caps how much of the gold’s value you can borrow. Recent descriptions of the RBI framework effective April 2026 refer to tiers: up to 85% for loans up to ₹2.5 lakh, up to 80% for loans above that up to ₹5 lakh, and up to 75% above ₹5 lakh. Older calculators may still use a flat 75%.
- At a flat 75%, the base case would give about ₹2,68,125 instead of ₹2,86,000
Lenders can also offer less than the cap, so the LTV you’re quoted may be lower than the maximum.
5. Loan Size Slabs and Cliffs
Because LTV depends on the loan size, calculator results can behave unevenly near the slab boundaries. In a calculator that applies the 85% slab only when the resulting loan stays within ₹2.5 lakh:
- A gold value of ₹2,90,000 gives a loan of about ₹2,46,500
- A gold value of ₹3,00,000 gives about ₹2,40,000 (because the higher value pushes it into the 80% slab)
So a slightly more valuable pledge can show a smaller maximum loan in some tools. Lenders may apply the slabs differently, so treat results near the thresholds with caution and ask how your lender calculates.
6. Type and Condition of the Gold
- Making charges and wastage aren’t valued. Lenders value the gold content, not the jeweller’s labour charges, so a heavily crafted piece won’t fetch more than its gold content.
- Condition and hallmark can matter, and damaged or unverifiable items may be valued conservatively.
- Coins, bars, and ornaments may be treated differently under a lender’s policy, so check what’s accepted.
7. The Lender’s Policy
- Banks and NBFCs may set different LTVs, rates, and minimum or maximum loan sizes within the regulatory limits.
- Special schemes can change terms, such as the rate or repayment structure.
- Appraisal methods differ in practice, so the final figure at the branch may vary from the online estimate.
8. Interest Rate, Tenure, and Repayment Type
If your calculator also estimates interest or EMI, the rate and structure matter. On a ₹2,86,000 loan with interest-only payments:
- 9%: about ₹25,740 per year (₹2,145 per month)
- 11%: about ₹31,460 per year (₹2,622 per month)
- 14%: about ₹40,040 per year (₹3,337 per month)
Gold loans can have different repayment options, such as interest-only with a bullet repayment, EMIs, or a single payment at maturity. Choose the one the calculator is set to, or the results won’t match your actual loan.
9. Fees and Charges
Processing fees, valuation charges, and other costs aren’t part of the loan amount, but they affect your real cost. Ask for a full breakdown.
10. Data Entry and Tool Errors
- Wrong weight or carat entered
- An outdated gold price in the calculator
- Old LTV assumptions that don’t reflect current rules
- Rounding differences between tools
Always cross-check the inputs, and compare more than one calculator.
A Quick Checklist
- Use net weight, not gross
- Confirm purity from the hallmark
- Enter the current gold price and the right reference (24K or 22K)
- Check the LTV and slab rules that apply
- Include the rate and repayment type for cost estimates
- Ask about fees and policies
- Treat the result as an estimate until the lender’s appraisal
This is general information rather than financial advice, so consider speaking to a qualified adviser, and read the loan agreement carefully before pledging your gold.
Frequently Asked Questions
Q1. Why does a calculator give me a different answer from the lender?
The lender physically assesses the weight and purity, uses its own benchmark price and policies, and may apply LTV slabs differently, so the final figure can differ from the online estimate.
Q2. What’s the single biggest mistake in gold loan calculations?
Using the gross weight of jewellery instead of the net gold weight, which can overstate the loan by tens of thousands of rupees.
Q3. Does a higher gold price always mean a bigger loan?
Generally yes, since the gold’s value increases, but slab thresholds can make results uneven in some tools, so check how your lender applies them.
Q4. Do making charges increase my gold loan amount?
No, lenders value the gold content, not the jeweller’s making charges or wastage, so these don’t add to your eligible loan.
