Open the calculator →GetHossa Tools are free calculators for the questions investors run into most often: how far regular monthly contributions can grow with compound interest, how much income a dividend position pays after tax, and what your yield on cost is. They run right in your browser and don't require an account.
Every calculator comes with an article that explains the formula it uses, walks through a worked example and lists the common pitfalls — so you know what the result means and where its limits are. The numbers are illustrations, not forecasts or tax advice. New calculators are added over time.
A calculator answers "what if"; a portfolio tracker answers "what actually happened". When you want real numbers instead of assumptions, GetHossa records every dividend you receive and forecasts the next 12 months, compares your actual return with the S&P 500, and shows realized gains with FIFO cost basis for every position you've closed.
