StackFi Tools
Practical tools for metals buyers and on-chain asset holders
These free tools turn live market data into fast answers for real decisions, from the premium on a tokenized stock to junk silver melt value, ratio analysis, and unit conversions.
Bullion buyers often need quick math before making a move. If you are pricing a bag of pre-1965 dimes, comparing dealer premiums on one-ounce rounds, watching the gold-silver ratio for a rotation signal, or translating spot prices into grams for international quotes, a clean calculator saves time and prevents mistakes. StackFi built this tools hub to keep those workflows simple and close to the market data you are already using on the site.
Every calculator here runs entirely in the browser with no login wall and no backend dependency. The inputs are straightforward, the outputs are mobile-friendly, and the pricing assumptions stay transparent so you can sanity-check them against your own dealer quotes or stacking rules. Start with the tool that matches your immediate question, then jump into the linked silver guides if you want a deeper strategy view.
