A stock return calculator is an online financial tool that computes the total return generated by a stock investment — including both price appreciation (capital gains) and dividend income — over a specified holding period. It takes inputs of the purchase price, purchase date, current or sale price, any dividends received during the holding period, and brokerage and transaction costs, to calculate absolute return, annualised return (CAGR), and post-tax return. The stock return calculator enables investors to accurately evaluate the real performance of their equity holdings — accounting for the total cost of acquisition (including STT, brokerage, and stamp duty at purchase) and total proceeds (minus transaction costs at sale) rather than simply comparing buy and sell prices. In India, the stock return calculator also helps investors determine whether gains qualify as Long-Term Capital Gains (LTCG — shares held over one year, taxed at 12.5% above ₹1.25 lakh) or Short-Term Capital Gains (STCG — shares held under one year, taxed at 20%), which significantly affects the net post-tax return. Ventura's stock return calculator helps investors benchmark their individual stock performance against the Nifty 50 index return over the same period — determining whether the stock has generated genuine alpha or has simply participated in the broad market move.
