How to use this calculator
Pick the video quality you usually stream at, enter your average hours streamed per day and days streamed per month, and enter your monthly data cap in gigabytes. Click Calculate to see your estimated monthly data usage, how much of your cap that uses, and the daily and hourly usage behind it. Click Clear to reset all fields.
The formula
Streaming video is delivered at a bitrate, measured in megabits per second (Mbps). To convert a bitrate into data volume: GB per hour = bitrate (Mbps) × 3,600 seconds ÷ 8 bits per byte ÷ 1,000 (to get gigabytes), which simplifies to GB per hour = bitrate (Mbps) × 0.45. This calculator uses typical average streaming bitrates for each quality tier: about 3 Mbps for SD (480p), 5 Mbps for HD (720p), 8 Mbps for Full HD (1080p), and 25 Mbps for 4K Ultra HD. Actual bitrates vary by streaming service, content, and network conditions, since most services use adaptive bitrate streaming that adjusts in real time — these are representative averages, not a guarantee for any specific service.
Daily usage is the hourly rate multiplied by hours streamed per day, and monthly usage is daily usage multiplied by days streamed per month. Dividing monthly usage by your data cap gives the percentage of your plan the streaming would consume.
Interpreting the results
The highlighted cards show your estimated monthly data usage and what share of your data cap that represents. If the share exceeds 100%, your streaming habits alone would exceed your plan's allowance before accounting for any other internet use. The supporting cards show the daily usage and the hourly streaming rate implied by your selected quality, so you can see how quality changes add up.
