Gold Loan Amount Calculator: Estimate Your Loan Value

A gold loan amount calculator estimates how much a lender might offer against gold you pledge. Enter the gold’s net weight, purity, estimated price per gram, and the lender’s advance percentage to get an indicative amount; the lender’s valuation and terms determine the actual offer.

Formula

The calculator first estimates the value of the gold content, then applies an advance percentage to that value:

Estimated gold value = net gold weight × (purity ÷ 100) × gold price per gram
Estimated loan amount = estimated gold value × (advance percentage ÷ 100)

• Net gold weight (wt) is the weight of the gold itself, in grams, excluding stones and other non-gold components.
• Purity (pur) is the gold content expressed as a percentage. For example, 22-karat gold is often described as 91.6% pure, though an actual item’s assessed purity can differ.
• Gold price per gram (price) is a price you enter in your own currency. It should reflect the relevant gold price and purity basis used for your estimate.
• Advance percentage (ltv) is the percentage of assessed gold value used in this estimate. It is an input, not a claim about a lender’s limit or offer.

The first output is the estimated loan amount. The second shows the estimated value of the pure-gold content before applying the advance percentage. Both outputs use the same currency as the price input; the calculator uses “-” as the unit because no particular currency is assumed.

Worked Example

Using the calculator’s default values—20 g of gold, 91.6% purity, a price of 70 per gram, and a 75% advance percentage:

1. Convert purity to a decimal: 91.6 ÷ 100 = 0.916.
2. Estimate the pure-gold content: 20 g × 0.916 = 18.32 g.
3. Estimate its value: 18.32 × 70 = 1,282.40 in your currency.
4. Apply the advance percentage: 1,282.40 × 0.75 = 961.80.

Estimated gold loan amount: 961.80 in your currency. The estimated pure-gold value is 1,282.40. These are arithmetic estimates, not a lender’s valuation or commitment to lend.

Assumptions

• The gold price you enter is applicable to the item’s purity and is expressed per gram.
• Weight means net gold weight; stones, clasps, solder, and other materials are excluded.
• The entered advance percentage is applied directly to estimated pure-gold value.
• No fees, deductions, interest, taxes, or other charges are included.
• The calculation does not model a lender’s assay, eligibility review, valuation method, or offer terms.

How to Use the Estimate

Use the result as a rough valuation aid before discussing a pledge with a lender. It helps show how weight, purity, price, and the advance percentage affect the arithmetic. It does not tell you whether a lender will accept the item or what amount it will offer.

• Measure the relevant weight. Use net gold weight rather than the full jewelry weight. A scale reading for an ornament that includes stones can overstate the gold content.
• Check the purity basis. Purity may be stated in karats or as a percentage. This calculator takes a percentage: if a reliable assessment states 22 karat, a commonly used conversion is 22 ÷ 24 × 100, approximately 91.67%. Do not enter “22” as the percentage.
• Enter a matching price. Make sure the price is per gram and uses a purity basis that can reasonably be compared with the item. A price quoted per ounce, per 10 grams, or for a different purity must be converted before use.
• Use a clearly identified advance percentage. If you do not have a lender’s figure, test a range of possible percentages as scenarios, not as a prediction of an offer.

For instance, leaving the other defaults unchanged, reducing the advance percentage from 75% to 60% changes the estimate from 961.80 to 769.44. The gold-value estimate remains 1,282.40. This illustrates that the advance percentage changes the estimated loan amount, not the underlying value calculation.

What Can Change a Lender’s Valuation?

The calculator intentionally uses a simplified model. A lender may assess an item’s weight and purity independently, and the assessed figures may not match your inputs. Non-gold parts can be excluded from the weight, while workmanship or design value may not be counted as gold content. The price used for an assessment may also differ from the price you entered, and the lender may apply its own valuation and advance method.

Therefore, the result is not a guaranteed loan amount, a current gold-price quote, or an estimate of total repayment. A loan’s repayment depends on its actual principal, interest, fees, payment schedule, and other disclosed terms. Ask the lender for the written valuation and complete cost information before relying on any offer.

Common Calculation Mistakes

• Counting stones as gold: use gold-only weight where available. If the non-gold weight is unknown, the estimate has added uncertainty.
• Mixing units: enter grams and a price per gram. Convert other weight or price units consistently before calculating.
• Using karats as a percentage: 22 karat is not 22% purity. Convert it to a percentage first.
• Applying purity twice: if the entered price already represents the assessed value per gram of the item’s actual purity, applying the purity factor again may understate value. For this formula, enter a price per gram on a pure-gold basis.
• Treating the estimate as approval: the formula does not account for lender-specific checks, item acceptance, or loan terms.

Rounding can also cause small differences. This calculator keeps the entered values through the calculation and displays the outputs to two decimal places; a lender may use different precision or rounding.

Frequently Asked Questions

How do I calculate the amount I can get for a gold loan?
Multiply net gold weight by purity as a decimal and by the gold price per gram. Then multiply that estimated value by the advance percentage. The result is only an estimate; the lender assesses the item and sets its offer.

Should I enter 22 karat as 22 or 91.6?
Enter purity as a percentage, so use about 91.6 for 22-karat gold, not 22. An actual assessment can produce a different purity figure.

Does the calculator include stones or making charges?
No. It estimates gold content from net gold weight and purity. It does not assign value to stones, workmanship, or making charges.

Why is a lender’s amount different from the calculator?
The lender may determine a different net weight, purity, gold price, or advance percentage, and may apply additional assessment conditions. The calculator models only the values you enter.

Is the result the amount I will receive?
No. It is a mathematical estimate, not an approval or offer. The lender’s disclosure gives the exact figures and applicable terms. This result is an estimate, and the lender’s disclosure gives the exact figures.
