Formula

pure grams = weight × purity; loan = pure grams × price × LTV

How the calculation works

A loan against gold is lent against the pure gold content, not the weight of the ornament. One bhori is 11.664 grams, and at 91.7% purity that is 10.696 grams of fine gold. The difference is not small: valuing the full 11.664 grams at the same price gives 99,144 against 90,915, about 9% more than the metal actually contains.

The purity figure is where the errors are largest, because karats and percentages are not the same scale. 22 karat is 91.7%, not 22%. Entering 22 as though it were a percentage leaves the fine weight at under a quarter of its true value, and the loan figure with it. This is the single most expensive mistake the tool exists to prevent.

The loan to value ratio is applied last, to the value of the pure metal. Lenders keep it below 100% because the price of gold moves and they need the pledged metal to cover the loan if they have to sell it. A 75% ratio on this example supports 68,186.

When to use it

Worked example

One bhori (11.664g) at 91.7% purity and 8,500 a gram supports a loan of 68,186 at 75% of value.

Pure gold 10.70
Gross value 99,144.00
Fine value 90,915.05
Maximum loan 68,186.29

Common questions

How do I express purity?

As a percentage, not in karats. 22 karat is 91.7% and 18 karat is 75%.
