Beyond Burn Rate: Burn Quality (BQ) for Smarter Capital Allocation
Burn rate measures speed. Burn Quality measures value per euro. Use ΔPoS × Value at Gate / € Spent to fund milestones that retire risk and raise valuations.
In life sciences, managing cash is critical. But burn rate only tells you how fast you spend- not what you create. Burn Quality (BQ) is a simple way to compare uses of cash and fund milestones that reduce risk and build value on schedule.
What is burn quality?
Burn Quality quantifies the capital efficiency of a strategic decision (experiment, milestone, or hire). It lets you compare options and pick the ones that create the most value per euro.
Formula
- ΔPoS (Change in Probability of Success): improvement in likelihood of success after the activity (e.g., 10%→25% gives ΔPoS = 0.15).
- Value at Gate: the financeable value once you reach the milestone (e.g., clinical pilots signed, IND enabled, data package accepted).
- € Spent: fully loaded cost to reach that gate.

How to interpret BQ
- BQ > 1 → every euro spent creates more than one euro of risk-adjusted value.
- BQ < 1 → deprioritise or redesign the activity.
Examples
- A therapeutics team calculated BQ = 3.75 for tox studies → clear priority over other activities.
- A platform company compared options: deepen the lead (BQ = 2.4) vs. start a new indication (BQ = 1.0) → deepen first.
Investors don't buy runway; they buy a schedule of decreasing risk. Sharing your BQ for competing options shows discipline, earns credibility, and aligns your ask with value creation.
Take aways
- Fund gates, not generic activity.
- Prioritise by risk retired per euro.
- Communicate BQ to align founders, board, and investors.
