Abstract: A method for dynamic cash flow modeling may include a cash flow computer program executed by a computer processor: (1) identifying a plurality of cash flow forecasting models, each cash flow forecasting model having a different cash flow forecasting approach; (2) receiving a cash flow forecast request comprising a plurality of cash flow forecast parameters; (3) training each of the plurality of cash flow forecasting models using training data; (4) tuning each of the plurality of cash flow forecasting models to identify optimal hyperparameters for each cash flow forecasting model using a validation data set; (5) selecting one of the plurality of tuned cash flow forecasting models with a lowest error; (6) forecasting, using the selected tuned cash flow forecasting model, a cash flow forecast using the training data set and the validation data set; and (7) outputting the forecast from the selected tuned cash flow forecasting model.
