Reverse-calculate the effective rate per tola, gram, or ounce from money paid and weight received.
A rate finder back-calculates the effective rate per unit from a completed transaction. Given how much money was paid and what weight of gold or silver was received (at a specific karat or purity), it shows the actual rate per tola, per gram, and per troy ounce — both at the karat you bought and normalized to the pure (24K gold / .
Formula
Rate = Money ÷ Weight. Pure-equivalent Rate = Rate ÷ Purity Fraction.You just bought a gold piece, paid PKR 500,000 for 2 tola of 22K, and walking home you start wondering — was that actually a fair rate, or did you get fleeced? This calculator answers the question by back-calculating. Enter what you paid and what you received (with the karat), and it tells you the exact rate per tola, per gram, AND per troy ounce — both at the karat you bought and normalised to the pure 24K-equivalent for direct comparison against any published market rate. The 24K-equivalent is the key trick. Shop A in Saddar quotes you PKR 240,000 per tola for 22K; Shop B in Anarkali quotes PKR 245,000 per tola for 22K. Which is better? Most people just compare the raw numbers, but normalising both to 24K-equivalent (240,000 × 24/22 = 261,818 vs 245,000 × 24/22 = 267,273) shows Shop B is actually paying you PKR 5,454 more per tola of pure-gold equivalent — meaningful across a large sale. Equally useful for spotting overcharges on purchases: if today's published 24K rate is PKR 280,000/tola and your back-calculated 24K-equivalent rate on a recent purchase is PKR 305,000, the jeweller charged you about 9% above market — which is the bundled making-charge and shop margin. Helpful for jewellery valuation for insurance, auditing past purchases when the family budget is tight, and comparing quotes across multiple shops on the same morning before the rate fluctuates.
A rate finder back-calculates the effective rate per unit from a completed transaction. Given how much money was paid and what weight of gold or silver was received (at a specific karat or purity), it shows the actual rate per tola, per gram, and per troy ounce — both at the karat you bought and normalized to the pure (24K gold / .999 silver) equivalent. This is invaluable for verifying a jeweller's quote against market rates, comparing prices across shops, auditing past purchases, documenting transactions for insurance or tax, and spotting when you may have paid above or below market value.
Dividing the money paid by the weight received gives the effective rate per unit at that karat or purity grade. To compare against a 24K market rate (the international benchmark), divide this effective rate by the purity fraction — for example, if you paid for 22K at $65/g, the 24K-equivalent rate is $65 ÷ (22/24) = $70.91/g. Whenever an advertised or posted rate differs meaningfully from the back-calculated rate, the difference is the jeweller's margin, making charge, or a pricing discrepancy worth investigating.
Quick cross-reference: if the per-tola rate is X, divide by 11.6638 for per-gram, multiply per-gram by 31.1035 for per troy ounce.
| Per Tola (PKR) | Per Gram (PKR) | Per Troy Ounce (PKR) | Per Troy Ounce (USD ≈ 280 PKR/USD) |
|---|---|---|---|
| 200,000 | 17,149 | 533,493 | $1,905 |
| 250,000 | 21,437 | 666,866 | $2,381 |
| 275,000 | 23,580 | 733,553 | $2,620 |
| 300,000 | 25,724 | 800,239 | $2,858 |
| 325,000 | 27,868 | 866,926 | $3,096 |
| 350,000 | 30,011 | 933,613 | $3,334 |
| 400,000 | 34,299 | 1,066,986 | $3,811 |
Converting a per-tola rate to per-gram: divide by 11.6638 (e.g. 275,000 ÷ 11.66 ≈ PKR 23,580/g).
Converting per-gram to per-troy-oz: multiply by 31.1035 (for international spot comparison).
A reputable jeweller's 22K rate should be 91.67% of the 24K rate — any bigger gap is margin or error.

Paid PKR 500,000 for 2 tola of 22K gold → rate at 22K = PKR 250,000/tola; pure 24K-equivalent = PKR 272,727/tola.
Paid $2,000 for 1 troy ounce of 18K gold → $2,000/oz at 18K = $2,000/oz; pure equivalent = $2,666.67/oz.
Paid PKR 100,000 for 10 tola of .925 sterling silver → rate at sterling = PKR 10,000/tola; pure .999 equivalent = PKR 10,811/tola.
Paid PKR 300,000 for '4 tola 3 masha' (about 4.25 tola) of 21K → rate at 21K = PKR 70,588/tola; 24K-equivalent = PKR 80,672/tola.
Comparing two jewellers: Shop A charges $3,200 for a 40 g 22K chain (≈ $80/g at 22K); Shop B charges $3,100 for a 38 g 22K chain (≈ $81.58/g at 22K) → Shop A is slightly cheaper per gram.
Spotting overcharge: if the daily 24K rate is $75/g and you paid an implied $82/g 24K-equivalent, the jeweller took about 9.3% above market — that's the making charge or margin.
