Neither, in the abstract. The two models cross over at a break-even volume: divide the monthly subscription fee by what a single title typically costs, and you get the number of titles you need to watch each month for the subscription to pay for itself. Watch more than that, the subscription is cheaper. Watch fewer, individual purchases are cheaper. There is no third answer, and anyone who gives you one without asking how much you watch is guessing.
What complicates it is that the two models are not selling the same thing. Cost only settles the comparison if access, permanence and catalogue coverage are equivalent — and they are not. So the honest structure is: run the arithmetic first, then check whether the cheaper option actually does what you need.
How do you work out your own break-even point?
Take the monthly fee of the tier you are considering, divide it by the typical price of one title in the genre you watch, and round up. That is your break-even count.
titles needed per month = monthly subscription fee ÷ typical per-title price
For the numerator, FANZA publishes some of the figures and not others. Its help centre gives ¥8,980 a month as the top of the 月額動画 range, for 見放題ch デラックス, and prices the FANZA TV tier at ¥550 a month (tax included) as part of a DMM Premium membership, with the FANZA TV Plus option a further ¥1,078 a month (tax included). Registering DMM Premium through Apple or Google in-app billing costs ¥650 a month instead of ¥550 (FANZA and DMM help centres, checked 2026-08-03).
Two adjustments make the result honest rather than flattering:
Use the price of titles you would actually buy, not the cheapest on the site. Back-catalogue titles are consistently cheaper than new releases. If you watch new releases, dividing by a bargain-bin price gives you a break-even number that is far too low, and the subscription looks better than it is.
Count titles you would have paid for, not titles you would have watched. A subscription changes behaviour: people sample more when sampling is free at the margin. If a subscription gets you through fifteen titles a month but you would only ever have bought three, your real comparison is three purchases against the monthly fee — not fifteen.
That second adjustment is where most online comparisons go wrong. It is also why the subscription frequently loses for people who are convinced it wins.

What are you actually buying under each model?
Different products. The table below compares them on the dimensions that survive a price change.
| Monthly subscription | Single-title purchase | |
|---|---|---|
| What you pay for | Access to a tier's current catalogue for a period | Ongoing access to one specific title |
| What happens when you stop paying | Access ends entirely | Purchased titles remain under the platform's library terms |
| Catalogue access | Broad but bounded — a negotiated subset that rotates | Exactly what you chose, nothing more |
| Is a specific wanted title guaranteed? | No — inclusion is negotiated and can change | Yes, that is what you bought |
| Rewatch value | Only while subscribed, and only if the title stays in the tier | Not dependent on a recurring payment |
| Cost behaviour | Fixed monthly, independent of use | Scales linearly with how much you watch |
FANZA states both sides of that table explicitly. A purchase carries a viewing period set per product — its published examples are 2 days, 7 days, 30 days and unlimited — and even an unlimited one ends if you close the DMM account, if the title is withdrawn from sale, if the product number, sales floor or handling maker changes such that the DRM record changes, or if the period stops being unlimited for any reason. On the subscription side, a title whose distribution has ended stops playing even while your subscription is still valid, and downloaded files stop playing within two days of the subscription expiring (FANZA help centre, checked 2026-08-03).
Rotation differs by channel rather than being one policy. FANZA describes 見放題ch as refreshing by roughly 1,000 titles a month, and its own comparison table marks that channel as one where titles do leave, while marking 見放題ch デラックス and VRch as channels where distribution largely does not end — qualified by a note that some titles may still be withdrawn for unavoidable reasons (FANZA 月額動画 plan page and help centre, checked 2026-08-03).
The row that costs people the most money is the fourth. A subscription is a bet on the catalogue, not on a title. If there is a specific work you want, the subscription may simply not contain it, and no amount of value elsewhere in the tier compensates for that.
The row that causes the most disappointment is the second. "Purchase" implies ownership, but what you have is access under the platform's library terms — terms the platform writes and can change. It is more durable than a subscription, which ends the day you stop paying, but it is not a file on your hard drive. The streaming-versus-download guide covers where that distinction becomes concrete.
When should you choose the subscription?
Choose the monthly subscription when your viewing is high-volume and low-specificity — you watch a lot, you are not attached to particular titles, and you are comfortable with the catalogue deciding what is available.
The conditions that favour it:
- Your realistic monthly count clears the break-even number with margin, so a quiet month does not flip the maths
- You browse and sample rather than seeking specific works
- Your interests sit in the back catalogue, which is where subscription tiers are deepest
- You are watching now rather than building a library for later
- You will actually cancel during months you do not use it
That last condition is the one that quietly decides the outcome. Subscriptions are priced on the assumption that a meaningful share of subscribers forget to cancel. A plan that is excellent value in the months you use it is pure loss in the months you do not, and the cancellation guide exists because platforms do not make that step as easy as the signup.
When should you choose single purchases?
Choose per-title purchases when you watch occasionally or specifically — a handful of titles a month, or particular works you want reliably available regardless of what a catalogue does next.
The conditions that favour it:
- Your monthly count sits below break-even, or varies unpredictably
- You want specific titles, performers or studios rather than a browse
- You rewatch a small number of things, and want them not to vanish
- You want new releases, which are typically sold individually before entering any subscription tier
- You do not want a recurring charge to manage
There is also a non-financial argument. A subscription's marginal cost of watching one more thing is zero, which is pleasant and also the mechanism by which subscriptions expand consumption. Paying per title reintroduces a decision at each purchase. Some readers consider that a feature.
Is there a way to avoid choosing?
Yes, and it is usually the right first move: buy individually for a month, count what you actually bought, then decide.
One month of real data beats any estimate, because the number you need — titles you would genuinely pay for — is the one people are worst at predicting about themselves. A month of purchases also tests registration, payment and playback before you commit to a recurring charge, which matters if you are overseas.
The reverse order is worse. Starting with a subscription tells you how much you watch when watching is free at the margin, which is not the number the break-even formula needs. And if the tier turns out not to carry what you wanted, you have paid to learn the catalogue rather than to watch it.
