A plan with 100 Mbps is certainly enough to let you stream in 4K on three or four devices and do a bunch of other cool stuff on multiple devices in a small-to-medium sized household (say, 2–6 people).

Mediacom gives you exponentially faster speeds with each $10 per month more you spend. It’s also generous with data caps, giving you a ridiculously high 6,000 GB of data (!!!) to use per month if you sign up for the 1Gig plan. Most internet providers have data caps of around 1,000 GB per month, so 6,000 GB is, um, quite a lot.

These speeds aren’t available in every service area. At that price point, you may have to settle for 100 Mbps, which honestly is still quite fast. If you really need superior performance, though, consider spending $20 more per month for the truly stupendous 400 Mbps speeds.

What’s the best RCN internet deal?

The best RCN deal is the 100 Mbps plan, which costs $29.00 or $34.99 per month (depending on your service area). It’s fast and it comes with no contract requirements or data caps. You can usually snag a coupon to get free installation too.

Like Xfinity, RCN’s prices vary based on where you are in its service area, so you may be paying slightly more or less in Chicago for the same speeds compared to a customer in Boston or New York.

Even so, you’re bound to get a solid deal from RCN. Its plans have fast speeds, no contracts, no data caps—and they usually come at a lower price than the nearest competitor. You can’t go wrong with RCN.

New customers in Washington, DC can get no-cost installation, a subscription to the TiVo Stream 4K service, and a $100 VISA Prepaid Card when signing up for a qualifying plan. If you’re in Chicago, you can get a 940 Mbps internet plan for $44.99 per month—a bit cheaper than it used to be there.

Last but not least, RCN’s famed coupon page is devoted to deals and bargains—mostly coupon codes to get free installation on internet service. Installation normally costs you $50–$100 with RCN, so that’s a nice savings.

Internet deals FAQ

Who has the cheapest and best internet service?

If you don’t qualify for a low-income internet program, then the cheapest and best deal is Xfinity’s Performance Starter Plus plan. It costs under $50 per month (plus the cost of installation, equipment, taxes, and other fees) and gives you a respectable 25 Mbps download speeds. That ain’t the fastest, but it’ll work great if you live in a small household and want to do streaming, gaming, and other online stuff on a couple devices.

Pro tip:

If you’re struggling to make ends meet in difficult times, read our affordable internet guide to find other ways to access low-cost Wi-Fi.

What is the best deal for home internet?

The best all-around deal for home internet is the AT&T Fiber Internet 100 plan for $35 a month. It delivers download and upload speeds of up to 100 Mbps on a fiber network. That’s a sweet price for great internet.

If fiber internet isn’t available in your area, don’t fret. You can still find fast internet deals near you. Spectrum and Xfinity both offer excellent plans featuring speeds between 100 to 200 Mbps for around $50 a month. Both providers have internet networks that run over coaxial cables, which are typically quite reliable and consistent.

Who has the cheapest internet service?

Xfinity and Mediacom have the cheapest internet service, both offering plans that deliver between 25–60 Mbps for around $20 a month.

If you’re living on a low income or have students in the house, you can apply for a low-budget internet program from Xfinity, Spectrum, Optimum, Suddenlink, or Mediacom. These ISPs all have cheap plan options for qualifying customers and are all committed to offering price breaks due to new coronavirus concerns.

How much should I pay for internet?

You should pay on average about $60 a month for solid and dependable internet. Keep in mind that doesn’t include equipment or installation fees you might have to pay to get started.

Of course, internet costs vary wildly depending on what you want out of your Wi-Fi. You can get internet for as low as $10 a month if you aim for a cheaper plan with less speeds or have been approved for a low-income program. But if you need gigabit speeds, a bundle package with internet and TV, or other advanced services, you’ll likely pay even more than $60 per month.
