How to Use the Global Surgery Calculator
This calculator estimates Disability-Adjusted Life Years (DALYs) for a surgical condition in a given population. Follow these steps:
- Enter Population – Input the total population number (e.g., 1,000,000). Must be a non-negative integer.
- Enter Prevalence (%) – Input the percentage of the population affected (e.g., 5 for 5%). Must be between 0 and 100.
- Enter Disability Weight – Input a value between 0 (perfect health) and 1 (death) representing the severity of the condition (e.g., 0.5).
- Enter Duration (years) – Input the average duration of the condition in years (e.g., 1). Must be non-negative.
- Click "Calculate DALYs" – The result will display the total DALYs and a breakdown of the formula.
Formula: DALYs = (Population × Prevalence%) × Disability Weight × Duration
Example: For a population of 1,000,000 with 5% prevalence, disability weight 0.5, and duration 1 year: Cases = 50,000; DALYs = 50,000 × 0.5 × 1 = 25,000.

Frequently Asked Questions
DALY stands for Disability-Adjusted Life Year. It is a metric that quantifies the burden of disease by combining years of life lost due to premature mortality and years lived with disability.
Cases are calculated as Population multiplied by Prevalence (as a percentage). For example, a population of 1,000,000 with a prevalence of 5% yields 50,000 cases.
Disability weights range from 0 (perfect health) to 1 (death). Common surgical conditions have weights between 0.1 and 0.6. Consult the Global Burden of Disease study for specific values.
