The article describes the components of financial forecasting. Three models of financial planning are considered. The sequence of forming the cash flow report is outlined. Conclusions. The calculation of the forecasted financial potential of the business entity must be carried out on the basis of long–term net profitability (profitability from operations with fixed assets, namely profit from investment of fixed capital) and financial stability, taking into account the forecast of increased profitability of equity capital, growth, preservation or restoration of liquidity. The forecasted financial potential should be based on the generation of net cash flow, which would allow, due to the growth of gross revenue and return on equity, to increase or restore lost financial stability, especially the ratio of current solvency, taking into account the effect of operating and financial levers and the realism of the forecast of the growth of own working capital in the monetary form.
