Monthly Phone Bill Calculation Formula

$$\text{Total} = (T \times CPM) + (S \times CPS) + (D \times CPD) + F$$

This formula calculates your phone bill by multiplying your talk minutes (T), sent SMS (S), and data usage in GB (D) by their respective costs per unit (CPM, CPS, CPD), then adding any fixed monthly charges (F).

The Phone Bill Estimator is useful for anyone on a prepaid or pay-as-you-go mobile plan. Enter your expected monthly usage — minutes, SMS, and data — along with per-unit costs and any fixed fees. The calculator will show you the total bill, making it easier to manage your phone expenses or compare different carriers and plans. Perfect for students, families, and budget-conscious users.
