Smartphone Data Calculator

Most cell phone carriers have gone to tier pricing for data plans. This can save lighter users of data up to $180/year over unlimited plans. However, it isn't that easy to figure out how much data you are consuming. Use the calculator below to estimate your monthly consumption of data. As you make an estimate for each activity, the Total Monthly Data Usage will update, as will the Recommended Plan table.

Estimated Total Monthly Data Usage:

The usage estimates for each activity built into the calculation are based on a blend of the estimates used by major carriers in the data calculators at their websites. We said it at the top of the page, and we'll say it again here: Actual data usage will vary widely by activity and device. MyRatePlan does not warranty the accuracy of these estimates.

Note also that 1 megabyte (MB) = 1,024 kilobytes (KB) and 1 gigabyte (GB) = 1,024MB.

Keep in mind that the data consumed for an activity can vary widely, and the same activity can use different amounts of data on different devices. Therefore, treat these projections as a very rough estimate. If you do go with a less-than-unlimited data plan, keep track of your data usage throughout the month to avoid billing surprises. Also, try and use free Wi-Fi connections for data as much as possible as this will not count against your usage allowance. Contact your carrier directly if you find a need to increase or decrease your data plan.

Mobile Hotspot: Many smartphones can share a cellular data connection with laptops and other devices. This sharing is usually via Wi-Fi, but can also be by Bluetooth or cable. Depending on the carrier, there may be an additional cost for this feature. If you'd like to include the cost in your calculation, check the box below. Data used counts against your plan's allowance, so keep that in mind when you are estimating how much data you need.
