Consider how many so-called “free” services we use from the moment we wake up until we go to bed: checking social media for free, sending messages for free, watching clips for free, using email for free, searching for information for free, opening maps for free, or even getting free Wi-Fi at a coffee shop.
Many services are so convenient that we rarely question where these companies earn their money. For consumers, the word “free” is very straightforward: if we don’t take out our wallet, don’t swipe a card, and no money is deducted from our accounts, we tend to feel like we aren’t paying anything.
However, in the digital business world, “free” may not mean costless. Instead, the price we pay might not be in cash. We might be paying with our time, attention, data, usage behaviors, or habits that keep us staying longer with a service.
At the same time, the digital life is also filled with another type of expense that seems small each time: monthly fees. These include phone bills, internet charges, streaming services, music subscriptions, cloud storage, productivity software, fitness apps, and various digital tools.
When signing up for each service, we often think, “It’s only a little over a hundred baht a month.” But if we have ten such monthly fees simultaneously, that small amount adds up. This is the intriguing aspect of the digital economy: some things seem to have no price, while many others have prices so small that we barely notice paying. Yet, combined, the true cost of “free” can be greater than expected.
Ask yourself a simple question: if social media platforms have hundreds of millions of users and allow us to use their services without charging fees, how do these companies pay for servers, staff, technology, and system development? The answer is that, in many cases, “we” are not the direct paying customers but part of what generates revenue for the business.
Many platforms generate income through advertising. The more users they have, the more valuable ad space becomes. The better they understand user interests, the more targeted the ads are. The longer we stay on the platform, the greater the opportunity to generate revenue. Small data points — such as which videos we watch longer, what topics we search for, what we “Like,” what products we’ve purchased, or our current travel interests — when aggregated from many users, become valuable business assets that help companies understand what people want.
Another thing we pay without realizing it is “time.” We might intend to watch just one clip on our phone, but when we look up, half an hour has passed. That 30 minutes doesn’t just disappear; along the way, we’ve seen multiple ads, generated more behavioral data, and helped the system learn what keeps us engaged longer.
This is the idea behind the Attention Economy, where human attention becomes a business resource. Everyone has different amounts of money, but everyone has the same 24 hours a day. Facebook, YouTube, TikTok, Netflix, games, online news, or online stores aren’t just competing within their industries; they’re competing for the same limited leisure time we have.
For businesses, being able to make users “stay just a little longer” has real economic value. That’s why the word “free” is so powerful: it removes nearly all barriers to decision-making. We don’t have to compare prices or consider value; we just download and try. Then the business’s challenge is to keep us from leaving.
In the past, business models were straightforward: we wanted a product, we paid money, and the product was ours. Buy a book once and it stays with us; buy software once and we can keep using it. But modern business models are shifting from one-time sales to building long-term financial relationships with customers.
Instead of paying 5,000 baht once, it might become 299 baht per month. To consumers, 299 baht feels easier to decide on than 5,000 baht. But for companies, if a customer stays for two years, 299 baht per month can add up to more than 7,000 baht. More importantly, companies receive monthly revenue, making forecasting income and cash flow easier without starting sales from zero each month. This is the appeal of subscription businesses.
One strategy that perfectly links “free” with “monthly fees” is the Free Trial—offering 7 days free, one month of Premium free, or a basic version free to start. On day one, we think, “Trying it costs nothing.” But after a while, playlists, photos in the cloud, work files, viewing histories, and other data accumulate. Switching to another service then involves not just money but also time, hassle, and the feeling of “starting over.” This is called Switching Cost in business.
Sometimes, customers stay not because they love the brand more each month but because staying is easier than switching. This is why subscriptions are powerful: businesses don’t need to sell new products constantly; they just need to keep us in the system long enough.
Look at your own statement and count how many automatic monthly deductions you have: phone bills, internet fees, streaming services, music subscriptions, cloud storage, work software, photo editing apps, fitness apps, online news, or services you might not even remember subscribing to.
Each amount may not seem intimidating because humans feel large sums more clearly than many small amounts that slowly add up. This is why businesses like to break big prices into daily or monthly rates. Saying “only 10 baht a day” feels different from “3,650 baht a year,” even though it’s the same total. When multiple subscriptions accumulate, consumers may experience Subscription Fatigue—the exhaustion from too many monthly fees.
However, subscriptions are not inherently bad. In many cases, they let us access quality services without paying a large sum upfront and can be more cost-effective if used regularly. Problems arise when we stop asking ourselves, “Am I still using this?” The most dangerous fees are not subscriptions we use daily but those we’ve forgotten we have.
Looking more broadly, this model is shifting the economy from ownership to access. We don’t need to own music because we pay to listen to all songs. We don’t need to buy movies because we subscribe to entire libraries. We don’t need to buy software because we rent it monthly. We don’t need our own storage space because we can rent cloud storage anytime. The benefit is greater convenience, but the question is, if one day we stop paying, what do we really own?
For consumers, this may be a reason to periodically review their “life rentals” to distinguish between things that truly add value and those fees deducted simply because we forgot to cancel. For businesses, the key lesson is that continuous revenue models are attractive, but sustainable businesses cannot rely indefinitely on customers’ laziness to press Cancel. Ultimately, customers must feel that every monthly deduction brings them something worthwhile.
In a world where every company wants to be on our credit card charging 99, 199, or 299 baht monthly, the next competition won’t be about who signs up the most members but who can keep customers willing to pay after the initial excitement fades.
Ultimately, the words “free” and “monthly” may be the two most powerful terms in the digital business era. The first gets us in without much thought, and the second keeps us staying without feeling like we pay much. Meanwhile, we may be paying with invisible costs — time, attention, data, habits, and small amounts quietly leaving our accounts every month. So, perhaps the most expensive things aren’t those with the highest price tags but those whose cost we never questioned because we just assumed they were “free.”
