Stress Load Calculator — Quantify Your Allostatic Load
Calculate your total stress load using cortisol, HRV, sleep, and life-domain scores. Identify which inputs are eating your performance.
Stress is not one thing. It is the sum of physiological, psychological, environmental, and lifestyle inputs. Chronic activation of the HPA axis drives metabolic dysfunction, immune suppression, and accelerated aging. This tool quantifies your total load and shows you the highest-leverage input to remove.

What the calculator measures
- Morning cortisol (if tested) and your perceived stress
- HRV baseline relative to age
- Sleep efficiency and consistency
- Training stress score (sessions per week, RPE)
- Life-domain stressors (work, finances, relationships, health)
- Recovery practices (sauna, breathwork, social connection, time in nature)
Output
A 0-100 score where below 30 is sustainable, 30-60 is elevated, and above 60 is unsustainable for more than a few weeks. The tool returns:
- Your biggest contributor (often sleep or alcohol, not work)
- A 14-day load-reduction protocol
- Recommended biomarkers to track if score is sustained above 60
Why allostatic load matters
McEwen’s original framework: it is not stress that breaks you, it is the failure to recover from stress. Two men with the same training volume can have completely different stress profiles if one sleeps 7 hours and the other 5.5. The calculator focuses on the recovery side of the equation.
What to do with the result
- High score with poor sleep → sleep optimization protocol
- High score with low HRV → HRV Optimizer
- High score with elevated cortisol → phosphatidylserine, ashwagandha trial, address chronic stressors
