Subscription Cost-Benefit

🗣
What is cost-benefit analysis? A process used to measure the benefits of a decision in comparrison to its cost. Essentially, benefit should always outweigh cost. - In this example, every month there is a select property that asks for the value of a subscription's benefit. That value correlates with a number between -2 ... 0 ... 2. - Using the monetary value of the same subscription, I created a benchmark formula to help me determine if the subscription is still worth the cost. - There is a new cost property that collects all subscriptions to keep and provides a new monthly cost as a SUM at the bottom of the table.
