For a single user doing basic browsing, 25 Mbps is enough. For a family of 4 with multiple streaming devices and video calls, 200–300 Mbps is more realistic. If you work from home and run video conferences daily, aim for at least 100 Mbps download and 20+ Mbps upload. Our calculator tells you the exact number based on your real usage.
ISPs advertise "up to" speeds — meaning the theoretical maximum under perfect conditions. In reality, speed varies based on network congestion (especially evenings), your router's age and placement, the number of devices sharing your connection, and how far you are from your ISP's infrastructure. A delivery rate of 70–85% is considered acceptable. Below 60% warrants a call to your ISP.
We divide your monthly bill by your actual download speed (not the advertised speed). This gives you a real-world cost-efficiency number. A good Cost per Mbps is under $0.50. If you're paying $60 for 150 Mbps actual speed, that's $0.40/Mbps — solid value. If you're paying $80 for 40 Mbps actual, that's $2/Mbps — significantly overpriced.
Each activity needs a certain amount of bandwidth: 4K streaming needs ~25 Mbps, HD streaming ~5 Mbps, online gaming ~15 Mbps, video calls ~10 Mbps. Our calculator adds up your selected activities and their counts, then checks whether your actual speed can handle them simultaneously without buffering or lag.
Fiber delivers symmetric speeds (equal upload and download) with much lower latency and more consistent performance than cable or DSL. If fiber is available in your area at a similar price to your current cable plan, it's almost always worth switching. The main advantage: you actually get what you pay for, usually 95%+ delivery rates.
