Percent predicted is calculated as Percent Predicted = (Actual FVC / Predicted FVC) x 100. If Actual FVC is 3.0 L and Predicted FVC is 4.0 L, what is the %Predicted?

Percent predicted shows how your actual FVC compares to what would be expected for a healthy person with similar characteristics, expressed as a percentage. You divide the actual value by the predicted value and multiply by 100. Here, 3.0 L divided by 4.0 L equals 0.75, and 0.75 × 100 equals 75%. So the percent predicted is 75%, meaning the actual FVC is three quarters of the predicted normal. If you test other possibilities, such as 60% or 50%, those would require smaller actual values (e.g., 2.4 L or 2.0 L) to fit the same formula.
