Last reviewed: 13 November 2026 (3 Jumada al-Akhirah 1448 AH)
In short
- We take the world price of a gold ounce in dollars from two independent sources and show it only when they agree.
- We convert it to rial at the fixed peg of 0.3845 rial per dollar.
- It is a raw price: no making charge and no shop margin.
How a price is made
- World priceGold ounce in dollars from two sources
- CheckA reading counts if they differ by 0.5% or less
- Into rialGram of 24 carat at the peg

Formulas
- 124 carat gram in rial = gold ounce in dollars ÷ 31.1034768 × 0.3845
- 2Gram of any carat = 24 carat gram × carat ÷ 24
- 3Price of any weight = gram price × weight in grams
- 4Silver gram in rial = silver ounce in dollars ÷ 31.1034768 × 0.3845
- 5Change % = (price now − last trading day's close) ÷ close × 100
31.1034768 grams in an ounce, and 0.3845 rial per dollar under the rial's peg (one rial is about 2.6008 dollars).

- Making charge
- The shop's margin when selling and buying
- Taxes and fees
Ask the shop for the final price before buying.
Why do some sites and shops show higher prices?
We show the raw gold price. Some sites that shops rely on show a selling price with additions, such as:
- A dollar rate above the peg, such as 0.3862 instead of 0.3845, which lifts every carat by about 0.5%.
- A fixed amount added per gram or bar, such as one rial on a gram of 24 carat, or 15 rials on ten tolas.
- Slower updates of the world price, hourly for example, so it lags the market.
- Rounded carat shares, such as 0.916 for 22 carat.
These are the seller’s additions, not part of the gold price. Enter the shop’s price in the calculator to see how much they are.
