About Reward Chart Progress Calculator

Progress is stars earned over stars needed, and the finish estimate divides the stars still needed by the daily earning rate. A visible countdown in days keeps a chart credible; goals that are more than a couple of weeks away rarely hold a young child's attention.

Formulas

Progress

progress % = stars earned / stars needed x 100

Days to goal
