Telehealth Data Usage Calculator

Why video doctor visits use more data than you think

A quick follow-up with your doctor feels nothing like streaming a movie — but to your data plan, it is almost the same thing. Most telehealth platforms run HD video at around 12 MB per minute, so a 20-minute consultation quietly burns about 240 MB. Add a couple of follow-ups and a family member's appointment, and you can spend close to a gigabyte a month without ever noticing. On a tight mobile data cap, that invisible bill is what pushes you into overage territory.

How this calculator does the math

Enter how many video visits you have per month, how long each one lasts, and the call quality. The calculator multiplies visits × minutes × the per-minute rate for your quality: audio-only (about 1 MB per minute), SD video (about 5 MB per minute), or HD video (about 12 MB per minute). It then converts the total to GB and shows it as a share of your monthly cap, with a plain-English verdict on whether your cap can take it.

Worked example — four HD visits a month

Say you have four appointments a month, 20 minutes each, on HD video: 4 × 20 × 12 = 960 MB, or about 0.94 GB. On a 10 GB plan that is just 9.4% of your cap — video visits barely dent your data. But put those same four visits on a 1 GB plan and the verdict flips: the visits alone would eat nearly the whole plan, and switching them to audio-only would cut that to about 80 MB a month.

Practical tips to keep telehealth off your data cap

Take visits on Wi-Fi whenever you can — it is the biggest lever by far. If the doctor does not need to see you, switch to audio-only: it uses roughly one-twelfth the data of HD video. Close background apps and pause cloud backups during the call. And check whether your plan throttles video to SD — for a routine follow-up you will not miss the pixels, and you will save a meaningful slice of data.
