Frequently Asked Questions
ROK stands for Return on Knowledge, a metric that measures the efficiency of your investment in learning by comparing the annual income increase to the total cost (including opportunity cost of time).
Opportunity cost is estimated as hours spent multiplied by $20 per hour, representing the average hourly wage you could have earned otherwise.
You can input an estimated future increase or use the calculator to compare different learning options.
