What profitability models have you used for forecasting a project?

For forecasting a project’s profitability, I typically use several models including the discounted cash flow (DCF) analysis, which estimates the present value of future cash flows, and the internal rate of return (IRR), which helps assess the profitability of potential investments. Additionally, I utilize break-even analysis to determine the sales volume needed to cover costs, and scenario analysis to evaluate how different variables impact profitability under various conditions. These models collectively provide a comprehensive view of potential financial outcomes.
