Cable TV is an outdated concept. You pay an ever-increasing bill every month for thousands of shows you’ll never watch. When you do want to watch, you have to organize your life around the TV schedule or set up your own DVR.

Buying episodes and streaming TV shows online may be cheaper than paying that cable bill. It all depends on what you want to watch and how much you’re paying for cable — we’ll walk you through what you need to know.

How Much Does Cable TV Cost?

To really crunch these numbers, you’ll need to understand how much you’re actually paying for cable. Cable TV bills vary based on the amount of channels you’re paying for, whether you’re getting a bundle along with Internet and landline phone service, your cable provider, where you live, and so on. Everyone’s cable bill will be a bit different, so understanding what you pay will help you do the math on your own situation.

According to the NPD Group, the average monthly pay-TV bill in the USA was $86 in 2011. NPD predicts the average monthly pay-TV bill in the USA will reach $123 in 2015 and $200 by 2020, so cable TV is only becoming more and more expensive.

Buying, Paid Streaming, and Streaming With Ads

First, let’s run down all the Internet-based TV options available to you. There are several different types of TV streaming services you need to care about:

Free Streaming With Ads: Some TV shows are available for streaming online right after they’re aired and can be watched for free. The downside is that the streams have commercials you have to watch — but, then again, you’d have to watch commercials even if you were paying for TV. Hulu has some free shows with commercials. Other shows are available elsewhere — for example, full episodes of The Daily Show and The Colbert Report are available for streaming on each show’s official website. You may also find such episodes on each TV network’s website.

The Price of an Episode

On iTunes, you can expect to pay about $2.99 to $3.49 for an HD episode and $1.99 to $2.49 for an SD episode. You can also buy season passes to get an entire season for cheaper, and these prices will vary depending on the amount of episodes you get in a season.

So, When is it Cheaper?

Whether this is cheaper than cable depends on how many TV shows you watch and how new they are. For example, if you’re a person who watches every new TV show the moment it airs, you should stick with cable. On the other hand, if you’re a person who only watches old shows that are available on Netflix, you’d save a lot of money by dropping cable and sticking with Netflix. If you only watched a handful of shows per year, you could buy those shows — or stream them even cheaper if they were available for streaming — and save money by dropping cable.

Let’s say you pay $86 per month for cable. And let’s say you buy TV show seasons at $40 each on iTunes — some will be cheaper. You can then buy two full seasons per month — that’s twenty-four seasons per year — and have some extra money left over to pay for Netflix. This is a very rough example — to get a real one, you need to focus on the specific shows you actually want to watch.

Finding Where Shows Are Available

Just Watch allows you to search for TV shows and movies and see where they’re available for streaming or digital purchase. Searching a website like this one is much faster and more convenient than searching every individual service.

Roku streaming boxes also have a universal search feature that allows you to search all your Roku’s channels for content and see where a TV show or movie is available. Of course, the Roku doesn’t support iTunes so not every service will be displayed here. This feature is also only available to Roku users in the USA and not in Canada.
