Gold Calculator: Buyer Desk

This app is a worksheet for mixed-karat gold lots. For each item you enter weight, karat or fineness, and any deduction for stones or other non-gold parts. Price, currency, weight unit, source, and capture date are all entered by you. It then shows fine-gold mass, a melt estimate, and your offer as a percentage or fixed amount, with the assumptions kept visible.

Quotes can be saved as dated snapshots with revisions kept in history. The listing mentions exporting a customer estimate as PDF and an internal CSV worksheet. The app does not provide live prices, test authenticity, or recommend an offer — results come only from your own inputs.

Why no subscription? Calculations are unlimited and free, and the first three distinct quote saves are included. Further saves need Pro, which is sold as monthly or annual subscriptions or as a lifetime purchase at $69.99 — the lifetime option avoids the recurring fee.
