The Perceived Stress Scale (PSS-10) is the most widely validated self-reported stress measurement tool in psychological research. Developed by Dr. Sheldon Cohen, it measures how stressful you find life situations in the past month. Think about how you've felt and thought over the last 30 days when answering each question.

How to Use the Perceived Stress Scale Calculator
The PSS-10 stress calculator uses the standardized Perceived Stress Scale questionnaire. Each of the 10 questions asks about stress-related thoughts and feelings over the past month. Four questions are reverse-scored (higher answers indicate lower stress), which the calculator handles automatically.
Rating Your Responses
Answer honestly based on how often you felt this way in the past 30 days. "Never" = 0 points, "Almost Never" = 1, "Sometimes" = 2, "Fairly Often" = 3, "Very Often" = 4. For reverse-scored questions (4, 5, 7, 8), the scoring is automatically flipped.
Interpreting Your Score
A total score of 0-13 reflects low perceived stress — your coping resources appear sufficient for current demands. A score of 14-26 reflects moderate stress — some areas may benefit from attention. A score of 27-40 reflects high perceived stress that may be affecting health, relationships, and cognitive function.
Using Your Score Over Time
The PSS-10 is most valuable as a tracking tool. Retaking it monthly lets you see whether stress management interventions are working. Common effective interventions include consistent aerobic exercise, mindfulness meditation (10+ minutes daily), CBT techniques, and improving sleep quality.

FAQ
Is this stress calculator free?
Yes, completely free. No signup required. All data processed locally in your browser.
What is the PSS-10?
The Perceived Stress Scale (PSS-10) is a validated psychological instrument developed by Dr. Sheldon Cohen in 1983. It is the most widely used self-reported stress measure in research and clinical settings. The 10-question version measures how stressful people find their lives in the past month.
What do PSS-10 scores mean?
PSS-10 scores range from 0 to 40. Scores of 0-13 indicate low stress, 14-26 indicate moderate stress, and 27-40 indicate high perceived stress. Scores are not diagnostic but provide a useful self-assessment benchmark.
Is this tool confidential?
Yes. Your answers never leave your device. All calculations are performed locally in your browser, and nothing is stored or transmitted.
What should I do if my stress score is high?
A high PSS-10 score suggests significant perceived stress that warrants attention. Evidence-based approaches include regular exercise, mindfulness meditation, cognitive behavioral therapy (CBT), sleep optimization, and social support. If stress is significantly impacting your daily life or you feel overwhelmed, speaking with a mental health professional is recommended.
How often can I retake this assessment?
The PSS-10 is designed to measure stress over the past month, so retaking it monthly provides meaningful trend data. Taking it more frequently (e.g., weekly) can capture shorter-term changes but may be influenced by very recent events.
