About StockAvg

StockAvg is a set of free calculators for weighted average cost across stocks, crypto, ETFs, options, futures and mutual funds. Every tool runs entirely in your browser, so the numbers you type never leave your device.

The math — total spending divided by total shares, fees included — is standard and never changes, so the site stays correct without updates.

StockAvg is maintained by an independent maker. It may show non-intrusive advertising once traffic justifies it. We do not collect or sell your data.
