Fixed and variable costs

🎯 Goal: Tell apart fixed costs (recurring, steady) and variable costs (change with use) to budget better.
Fixed costs recur steadily (tuition, internet). Variable costs change with use (snacks, outings). Sorting them helps control a budget.

Let’s explore

📌
Fixed: about the same monthly → easy to predict.
🌊
Variable: rises/falls with spending → easiest to cut.
✂️
To save fast, cut variable costs first.

Practice activity
