KDPH to WPM Converter: Exact Speed & Mistake Calculation Formula for Typing Exams

How to convert Key Depressions Per Hour (KDPH) to Words Per Minute (WPM), calculate Gross vs Net Speed, and compute mistake penalties in SSC and Court exams.

Most government recruitment notifications express speed in Key Depressions Per Hour (KDPH) or Words Per Minute (WPM). Understanding how these metrics relate ensures you hit your target score during timed drills.

2. Gross Speed vs Net Speed Formulas

🔹 1. Gross Speed (Raw WPM)

Gross speed measures the total number of words typed per minute regardless of mistakes.

$$\text{Gross Speed (WPM)} = \frac{\text{Total Key Depressions Typed} / 5}{\text{Time Duration in Minutes}}$$

🔹 2. Net Speed (Actual Qualifying WPM)

Net speed deducts your mistake penalty from the gross speed.

$$\text{Net Speed (WPM)} = \text{Gross Speed} - \left(\frac{\text{Total Mistakes} \times \text{Penalty Factor}}{\text{Duration in Minutes}}\right)$$

🔹 3. Accuracy Percentage

$$\text{Accuracy (%)} = \left(\frac{\text{Correct Keystrokes}}{\text{Total Keystrokes Typed}}\right) \times 100$$
