About the Data Plan Cost Calculator
Mobile plans often charge a flat rate for a set amount of data, then bill extra for anything used beyond that limit. This calculator adds those overage charges to the base plan cost.
Formula: Overage = max(0, Data Used − Included Data); Total Bill = Base Plan Cost + (Overage × Overage Rate per GB)
Tracking your effective cost per GB over a few months can help decide whether it's time to upgrade to a plan with more included data.
