Plan the complete cost
All tools work with your own inputs. No paid data feed or sign-in is needed to calculate.
Gold value calculator
Estimate a purchase using your quotation. The rate must already match the jewellery purity.
Silver purchase calculator
Enter a per-gram quotation for the silver purity you intend to buy.
Platinum value calculator
Manual quotation calculator; not a jeweller price feed.
Copper value calculator
Manual per-kilogram quotation; exchange, industrial and scrap quotations are not interchangeable.
Gold jewellery bill calculator
Separate metal weight, making charges, wastage and your tax assumptions.
Making-charge comparison
Compare alternative percentage, per-gram and fixed making-charge quotes on the same metal value, before tax.
Budget-to-gold calculator
Find the maximum net metal weight within your budget under explicit charge assumptions.
Metal weight converter
Convert using explicit mass definitions; troy ounces differ from ordinary ounces.
Gold fine-metal content
Calculate theoretical fine-gold content from net alloy weight. This does not test or certify purity.
Jewellery invoice arithmetic checker
Compare an entered bill total with the stated calculation. Not a tax or legal certification.
Old-gold exchange estimator
Use the dealer's purity-specific buyback quotation, not a retail purchase rate.
Metal purchase return calculator
Use your total acquisition cost and achievable net sale proceeds, including charges.
Wedding jewellery budget planner
Allocate a budget to three editable quotation amounts. Values are your estimates, not retailer offers.
