Skill Fade Calculator (Assuming 1% skill loss per day)

What is the Skill Fade Calculator?

The Skill Fade Calculator shows how much your ability decreases over time, assuming a consistent 1% loss every day without practice. Whether it's a language, sport, coding, or any other skill — lack of practice causes a gradual decline in proficiency.

Why Track Skill Fade?

• Quantify how much performance declines with inactivity.
• Stay motivated to maintain regular practice habits.
• Plan realistic training and re-learning strategies.

How to Use the Calculator

• Enter your current skill level or performance score.
• Enter how many days of inactivity you expect.
• See how much your skill may decline over that time.
• Use this insight to plan the skill maintenance.
