Discount Rate Selection and Hurdle Inputs

Discount Rate Selection and Hurdle Inputs focuses on the rate assumptions used to translate future cash flows into present value. The central question is not merely which percentage was entered, but whether the rate matches the cash flow’s timing, currency, inflation basis, risk, tax basis, capital claim, and measurement purpose.

Start with Discount Rate for the valuation mechanics, selection frameworks, sensitivity examples, and distinction between valuation, central-bank, and public-policy uses.

This branch sits inside Discount Rates, Required Return, and Risk Premia. Use the broader section to compare Required Rate of Return, Risk-Free Rate, and Market Risk Premium.

What to Check

• Valuation date, payment dates, forecast horizon, and terminal-value measurement date.
• Nominal versus real inputs and pre-tax versus after-tax cash flows.
• Enterprise, debt, equity, project, or public-benefit cash-flow ownership.
• Currency, compounding, maturity, and benchmark conventions.
• Risk adjustments already reflected in cash flows or scenarios.
• Flat-rate assumptions versus maturity-specific discount factors.
• Market-input dates and any applicable accounting, regulatory, or government guidance.
• Sensitivity of value and decision thresholds to plausible rate changes.

Common Mistakes

• Selecting a rate to produce a preferred valuation.
• Using company-average WACC for a project with materially different risk.
• Discounting equity cash flow with an enterprise rate.
• Applying nominal rates to real cash flows or annual rates to monthly periods.
• Counting the same risk in both reduced cash flows and a higher rate.
• Treating a historical policy rate as current without checking the governing source.
• Confusing a central-bank lending rate, a valuation rate, and a price discount.
