Stock Calculators

Model discounted employee share purchases in MiniWebtool’s ESPP Calculator. Salary deductions, offering period, discount, lookback, share prices, and tax assumptions determine estimated shares, gross profit, and after-tax return for the sale scenario.

MiniWebtool’s Stock Average Calculator combines an existing holding with an additional purchase to find the weighted average cost per share. Compare position size and cost before and after, with an optional current-price input.

Estimate sensitivity to a market benchmark with MiniWebtool’s Stock Beta Calculator. Enter paired prices, periodic returns, or summary statistics to calculate beta and related regression measures, including alpha and R-squared.

MiniWebtool’s Stock Profit Loss Calculator accounts for purchase price, sale price, share count, and commissions. Review net gain or loss, ROI, and break-even price, with annualized return where holding-period information is provided.

Enter your shares, price, and a forward or reverse split ratio into MiniWebtool’s Stock Split Calculator to see the new share count, adjusted price, position value, cost basis, and any fraction.
