Gold Average Cost

The Gold Average Cost Calculator computes your weighted average cost per gram (or ounce) across all your gold purchases, accounting for different quantities, purities, and prices paid at different times. Enter each purchase with its date, weight, purity, and price. The calculator shows your cumulative average cost per gram of pure gold and plots it over time as a line chart, so you can see how each purchase moved your average up or down. Dollar-cost averaging into gold — buying small amounts regularly — is a popular strategy for building a gold position without timing the market. This calculator helps you track the effectiveness of that strategy and compare your average cost against the current spot price to see your overall gain or loss.
