Data usage by activity — what actually eats your GB
Before picking a plan, you need to understand how much data each activity consumes. The figures below are based on published estimates from Netflix, Google, Microsoft, and the FCC Broadband Speed Guide.
How much data does each household type really need?

|---|---|---|
| Single person, light use Email, social media, occasional streaming |
50–100 GB | 100–200 GB plan or basic unlimited |

Top US internet providers — data caps compared (2026)
Data caps vary significantly by provider and plan. Many providers throttle or charge overage fees once you exceed your monthly limit. Here is a current comparison of the major US internet service providers.
| Provider | Data cap | Overage fee | Notes |
|---|---|---|---|
| Xfinity (Comcast) | 1.2 TB/mo | $10 per 50 GB, up to $100/mo max | Unlimited add-on available for ~$30/mo extra. Most common cap in the US. |
| AT&T Internet | Unlimited | No overage | All AT&T fiber plans include unlimited data. DSL plans may vary by market. |
| Verizon Fios | Unlimited | No overage | All Fios fiber plans are truly unlimited with no throttling reported on residential tiers. |
| Spectrum (Charter) | Unlimited | No overage | Spectrum does not impose data caps as part of their standard policy. Subject to network management. |
| Cox Communications | 1.25 TB/mo | $10 per 50 GB block | Unlimited upgrade available. Cap applies to most residential plans by default. |
| T-Mobile Home Internet | Unlimited | No hard cap | Wireless home internet. May experience network management (deprioritization) during congestion above 50 GB. |
| Starlink (SpaceX) | Unlimited* | No overage fee | Residential plan is unlimited but subject to network priority management above 1 TB in congested areas. |
| Mediacom | 200 GB–6 TB | $10 per 50 GB block | Cap depends on plan tier. Entry plans cap at 200 GB — one of the lowest caps from a major ISP. |

Conclusion
Choosing the right internet plan starts with knowing how you actually use the internet — not guessing. If you stream HD video daily and occasionally video call, 300–500 GB/month is your ballpark. If your household streams in 4K, games regularly, or has a full-time remote worker, you need at least 1 TB or an unlimited plan.
Among the top US providers, AT&T Fiber, Verizon Fios, and Spectrum offer the cleanest unlimited plans with no hidden overage fees. Xfinity and Cox give you more flexibility in where they operate, but their data caps require monitoring if your household is data-heavy.
Use the activity table and estimates in this guide as your baseline, add up your household's habits, and match that number to a plan before you sign. A few minutes of planning now saves you from surprise overage charges every month going forward.
