How it works
Four taps from gold to dollars.
01
Weigh the piece
Use any scale. Type the weight in grams, pennyweight, or troy ounces. MeltMate converts automatically.
02
Pick the karat
10k, 14k, 18k, 22k, or 24k. MeltMate multiplies by the standard gold purity (e.g. 14k = 58.3% pure).
03
Read the payout
Live spot price × purity × your payout %. The exact dollar amount you'd hand over.
04
Save the transaction
Optional GPS location, optional note, time-stamped. Export to CSV any time.
The formula
pure_grams = weight_g × (karat ÷ 24) melt_value = pure_grams ÷ 31.1035 × spot_price_per_ozt payout = melt_value × payout_percent
