Compare calculators
Both calculators run independently — change the inputs on either side to compare results.
Depression Index Calculator
Compute a 0–10 depression-symptom index by combining inverted mood, energy, and direct social-withdrawal ratings. Useful for personal tracking; not a clinical diagnosis.
Depression Screening Calculator
Screen for depression symptoms using a simplified PHQ-9 methodology by scoring five core indicators like low mood, sleep issues, and fatigue. Use it as an initial self-check — not a clinical diagnosis.
Depression Severity Score
0 points
0-2 points across these 5 items suggests minimal depressive symptoms; the example score of 0 lands here. No further action is typically indicated by screening guidance.
This is the PHQ-2/PHQ-style sum of 5 items scored 0-3 (range 0-15); the PHQ-9 clinical cutoff for likely major depression is 10 on its full 27-point scale, so treat this short form as a screen only.
