The hurdle rate is the minimum return an investment or project must earn before it’s considered worth doing at all.
The idea
Every option competes against what you could otherwise do with the same money, time, or effort — its opportunity cost. The hurdle rate turns that comparison into a single number: a threshold return that a proposal must clear before it even enters the conversation. Set it too low and marginal projects crowd out better uses of scarce resources; set it too high and good opportunities get rejected. In finance, the hurdle rate is often built from a baseline cost of capital plus a risk premium, so riskier or less certain projects face a higher bar than safer ones. Framed this way, it’s opportunity cost made explicit and enforceable, rather than re-litigated case by case.
When to use it
- Comparing multiple investment or project proposals competing for the same limited capital
- Deciding whether a new initiative is worth pursuing at all, before spending time on a detailed business case
- Setting a personal bar for which opportunities deserve your time, not just your money
How to apply it
- Estimate your baseline cost of capital, or the return of your best readily available alternative
- Add a risk premium if the opportunity is less certain or less liquid than that alternative
- Reject or deprioritize anything that doesn’t clear the resulting threshold
- Revisit the rate periodically — your opportunity cost changes as your options change
Watch out for
- A hurdle rate set once and never revisited can silently misallocate resources as conditions change
- Overestimating expected returns to game a fixed hurdle rate is a common failure mode
- A rate that’s too conservative can lead to rejecting genuinely good opportunities out of excess caution
Related models
- Opportunity — the hurdle rate is a way of pricing opportunity cost explicitly.
- Compound Interest — the baseline return a hurdle rate is often benchmarked against.
