How to use this calculator
- Enter your typical daily data usage — check your phone or router's data usage stats.
- Read the projected weekly and monthly totals.
Assumptions
- Assumes consistent daily usage — actual usage often varies significantly day to day (e.g. streaming video some days, light browsing others).
Technical details: what the fields mean
- Typical daily usage
dailyUsageGb - Typical data used in a day, from your device or router's usage stats.
Methodology
Weekly usage = daily usage × 7. Monthly usage = daily usage × 30 — a simple projection assuming a consistent daily pattern.
Worked example
1.5GB/day
Inputs: dailyUsageGb=1.5
Result: 10.5 GB/week, 45.0 GB/month
Practical guidance
- Check your device's built-in data usage tracker over a full week for a more representative daily average than a single day's figure.
Common mistakes
- Basing the estimate on one unusually high or low usage day rather than a representative average.
