Quick Answer
Multiply each activity's hours by its data rate, add everything together, and then scale by the number of days in the month.
How to Use It
- Enter the number of hours you spend on each activity per day.
- Choose how many days are in the month you want to estimate.
- Click Calculate.
- Review the activity breakdown and total usage.
Formula
Daily data usage = sum of each activity's hours x GB per hour
Monthly data usage = daily data usage x days per month
Worked Examples
Example 1: 2 hours of HD streaming uses 4 GB per day.
Example 2: 1 hour of social media and 2 hours of browsing uses 0.36 GB per day.
Example 3: 30 days at 5 GB per day equals 150 GB per month.
How to Interpret Your Results

| Low usage | Your current plan leaves room for more activity. | Keep monitoring if your habits change. |
| Moderate usage | You are using a meaningful part of your allowance. | Good time to compare plan sizes. |
| High usage | Your activities are likely to exceed a small data plan. | Consider a larger plan or Wi-Fi use. |
