Key Features
- Calculate remaining data allowance
- Estimate daily data usage
- Compare costs between plans
- Track your data usage trends
Formula Used
The calculator uses the following formulas to determine your results:
Where:
- Total Data Allowance = Your plan's data limit in GB
- Data Used = Amount of data you've consumed so far
- Number of Days in Month = Current day of the month
- Monthly Cost = Your current plan's monthly fee
Worked Example
Let's look at an example to see how the calculator works:
Example Calculation
You have a 20GB data plan that costs $30 per month. You've used 12GB so far this month (on day 15).
Remaining Data = 20GB - 12GB = 8GB
Daily Usage = 12GB / 15 days ≈ 0.8GB/day
Estimated Cost = (12GB / 20GB) * $30 = $18
This means you have 8GB of data left, use about 0.8GB per day, and have spent approximately $18 of your $30 plan so far.
