Gold Polish Calculator — Grams-per-Tola Polish Loss → Grams Output
Gold polish loss is the small mass of metal removed during the final polishing and finishing of a jewellery piece. Sarafa Bazar jewellers typically quote polish loss as grams-per-tola (e.g., "1 g per tola" or "0.5 g per tola"), translating to a deduction from the gross gold weight when reconciling with the customer.
This calculator takes a polish-loss rate in grams-per-tola and your gross weight, then returns the net (post-polish) weight in grams plus the money-value difference at live international XAU/USD spot rates.
Polish loss math
Net grams = Gross grams − (Gross tola × polish g/tola). Where gross tola = Gross grams ÷ 11.664. Example: 50 g gross with 1 g/tola polish loss = 50 − (4.287 × 1) = 45.713 g net.
