Formula, assumptions, and example
Formula: DASI score = the weights of the twelve activities marked achievable added together. Predicted METs = [(DASI score × 0.43) + 9.6] ÷ 3.5; the maximum score is 58.2.
DASI is a structured self-reported functional-capacity instrument. This page accepts already-understood activity responses and adds the published weights, then displays the commonly used MET conversion as an estimate rather than a measured exercise result.
- The responses come from the approved DASI instrument and the user’s own functional history.
- A marked achievable activity contributes its specified weight; an unachievable activity contributes zero.
- The twelve weights sum to a maximum DASI score of 58.2 points.
- The displayed MET value uses the published linear conversion from score to estimated peak oxygen-use equivalent.
- The estimate is not measured VO₂ peak and does not establish exercise clearance.
- Pain, dyspnoea, fatigue, frailty, cognition, language, and assistance needs can affect responses.
- The calculator does not change the instrument’s administration, ask follow-up questions, or interpret perioperative risk by itself.
- Symptoms or a change in exercise tolerance need discussion with the responsible clinical team.
Worked example: DASI = 2.75 + 1.75 + 2.75 + 5.50 + 2.70 + 3.50 = 18.95 points; predicted METs ≈ 5.07.

How to use the Duke Activity Status Index (DASI) Calculator for a real question
Add the twelve scored DASI activity components and estimate the associated MET value without reproducing the instrument’s question wording. Start with one clearly defined goal, enter values in the units shown, and keep the result attached to the assumptions below.
What this answers
This tool is useful when your question includes DASI calculator, Duke Activity Status Index, DASI score. It returns the outputs declared in the calculator contract rather than a live quote, approval, diagnosis, or professional sign-off.
What you enter
Self-care activities marked achievable · Walking indoors marked achievable · Walking one or two blocks on level ground marked achievable · Climbing stairs or a hill marked achievable · Running a short distance marked achievable · Light household work marked achievable · Moderate household work or shopping marked achievable · Heavy work or moving furniture marked achievable · Yardwork marked achievable · Sexual activity marked achievable · Moderate recreation marked achievable · Strenuous sport marked achievable. Keep the same time period, unit system, and currency wherever the form requires comparable values.
How to check it
Run the worked example first, compare its output with the page's example, then change one input at a time. This makes an unexpected result easier to trace to a unit, boundary, or assumption.
Three checks before you rely on the answer
- Match the question. Confirm that the result means the quantity you need, not a similar-sounding percentage, balance, rate, or estimate.
- Match the inputs. Use the requested units and period, and read each hint before replacing the example values with your own.
- Read the boundary. Review the assumptions and limits. The responses come from the approved DASI instrument and the user’s own functional history.

Context and background
How health estimates should be read
Health calculators use measurements and population-level relationships to produce screening or planning estimates. They describe the supplied model; they do not diagnose, prescribe, or replace clinical judgment.
Many familiar health formulas began as practical ways to summarize measurements. Their limits matter as much as their output because individual bodies, medications, conditions, and professional standards vary.
Research and review
How this guide was researched
Researched by Hassan ALRowaie, Founder and editorial researcher at WorldCalculate.
This guide follows the live calculator's declared inputs, formula, worked example, assumptions, validation boundaries, and source-backed methodology. The review date describes editorial review of the calculator explanation; it is not a promise that external facts or rates remain current.
The Duke Activity Status Index turns everyday activity capacity into a weighted score. WorldCalculate focuses on the arithmetic and the distinction between a questionnaire-based estimate and a measured exercise test, so the result can support a conversation without overpromising what it knows.
What DASI measures
DASI is a twelve-component self-reported measure of functional capacity. The activities are weighted according to their expected energy demand and added into a score.
It is useful because everyday activity can give context when formal exercise testing is unavailable or not the immediate question.
DASI score formula
Add the weight for each activity the respondent marks as achievable. The weights produce a score from 0 to 58.2 points.
The associated MET estimate uses [(score × 0.43) + 9.6] ÷ 3.5. This is an estimate linked to the instrument, not a direct gas-exchange measurement.
How to use this page
Select yes only when the activity is achievable as the approved instrument defines it. Select no when it is not achievable, and avoid guessing from a single unusually good or bad day.
The page uses neutral activity labels and point values; use the authorized instrument for the full wording and administration context.
Worked example
If the selected activities contribute 18.95 points, the conversion is [(18.95 × 0.43) + 9.6] ÷ 3.5, or about 5.04 METs.
The result preserves the score and the conversion separately, making a transcription or formula check easier.
Why daily activity matters
Walking, stairs, household tasks, yardwork, recreation, and sport cover different levels of exertion. A pattern of limitations can be clinically useful even when the person has not completed a formal exercise test.
Activity is influenced by more than the heart and lungs, including pain, balance, strength, environment, mood, and access to help.
DASI versus an exercise test
A questionnaire reports what someone can do; a cardiopulmonary exercise test measures physiologic responses under controlled conditions. They should not be treated as interchangeable.
A score can support planning and discussion, but a clinician may need examination, testing, or a different risk tool for the actual decision.
Common response mistakes
Do not mark an activity yes because it was possible once if it is not part of usual capacity. Do not infer ability from age, diagnosis, or another person’s expectations.
If language, disability, assistive equipment, or cultural context affects a response, document that context rather than forcing a misleading binary answer.
Safety and limitations
A DASI score cannot clear someone for exercise or surgery, and a low score does not reveal a single cause. New chest discomfort, fainting, severe breathlessness, or rapidly worsening tolerance need medical attention.
Use the result with the full history, examination, local perioperative pathway, and the responsible team’s judgment.
FAQs
What is the maximum DASI score? 58.2 points. Are METs measured here? No, they are estimated from the score. Can the calculator replace a clinician? No; it is a transparent scoring aid.
