Internet Bill
Compute your internet bill including data overage fees.
About Internet Bill
Any data beyond the cap is multiplied by the overage rate and added to the monthly plan cost. Streaming can quietly blow past a data cap, and overage fees often dwarf the plan price unless you watch them.
Formula
Internet Bill
Overage = max(0, data used - cap) x rate; total = plan + overage
- overage rate
- Fee charged for each gigabyte over the data cap

Assumptions and limits
- The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
