Tank printer or cartridges: do the maths (2026)

Tank printers (Epson EcoTank, Canon MegaTank, HP Smart Tank) are sold as the definitive escape from the "ink rip-off". And for some people they are. For most, on the other hand, they're €230 that will take you almost two decades to recoup. The difference between one case and the other fits in a single question: how much do you print a month?

We'll give you the exact calculation, with 2026 numbers, so you don't get swept along by the marketing.

The essentials in 20 seconds

• Tank ink is dirt cheap (~€0.006/page), but you pay €180–300 up front to get access to it.
• The break-even point versus compatible cartridges is around ~9,600 pages: below ~250–300 pages/month, it doesn't pay off.
• A typical home prints 30–100 pages a month; the experts only recommend a tank from ~30 upwards, but the real break-even depends on what you compare it with.
• Switching from original to compatible cartridges brings the cost down from ~€0.10 to ~€0.03/page without buying a printer.
• Manufacturers like Epson promise up to 90% savings on ink (Epson Europe, 2025), but they always compare with original cartridges, not compatibles.

Why does tank ink seem so cheap? The mirage

The cost per page of a tank printer is real and ridiculous: around €0.005–0.01. Epson puts its EcoTank ink at around €0.0029 per page in black (LD Products, 2024). The trick isn't in the ink: it's that you've already paid €180–300 up front to get access to it.

The sales pitch is irresistible: "forget expensive cartridges, refill with ink bottles at pennies a page". And it's true. The problem is that this calculation hides the most important thing: if you already have a working printer at home, that money comes out of your pocket today, to save a few cents tomorrow.

A tank printer is an inkjet machine with integrated refillable tanks: instead of changing cartridges, you pour ink from bottles. The cost per page is the price of the ink (or toner) divided by the pages it yields under the ISO standard. These are the two concepts that will decide your purchase.

The right question isn't "is tank ink cheaper?" (it is). It's: "do I print enough to pay off the machine before it goes obsolete?"

In 2026, the manufacturers themselves acknowledge that the saving is conditional. Epson warns in its official calculator that "actual savings will vary considerably depending on tasks, print volumes and usage conditions" (Epson Europe: EcoTank calculator methodology, 2025). Translation: the "up to 90%" is a ceiling, not what you'll see.

How much does each option really cost? The numbers (2026)

At a home volume of 100 pages a month (1,200 a year) over 3 years, sticking with your current printer and compatible cartridges works out at ~€108; buying a tank printer, ~€252; and using original cartridges, ~€360. The one they push hardest is the second most expensive of the three. Indicative figures for the Spanish market:

Option	Machine (upfront cost)	Cost per page	Ink over 3 years (3,600 pp.)	3-year total
A. Your current printer + COMPATIBLE cartridges	€0 (you already have it)	~€0.03	~€108	~€108
B. Buy a tank printer + its ink	~€230	~€0.006	~€22	~€252
C. Your current printer + ORIGINAL cartridges	€0	~€0.10	~€360	~€360

Read the table slowly, because it's counterintuitive:

• The option they push most (the tank, €252) is more expensive than sticking with your printer using compatible cartridges (€108).
• The "traditional" option (original cartridges, €360) is by far the worst.
• At this level of printing, switching to a tank is losing money. What's bleeding you dry isn't your printer: it's the original cartridges.

If you want to fine-tune your own case with your exact volume, we have a dedicated guide: the real cost of printing.

How many pages does a tank take to pay off? The break-even point

The number that decides everything: a tank doesn't pay off until you recoup the ~€230 upfront with what you save per page. Versus a compatible cartridge you save about €0.024/page (€0.03 vs €0.006). Divide and out comes the threshold almost nobody shows you:

€230 ÷ €0.024 ≈ 9,600 pages

In other words, the tank wins only if you print more than ~250–300 pages a month sustained over three years. Below that (where the vast majority of homes sit) you're better off keeping your printer and using compatible cartridges.

Watch out for the nuance that changes the whole conversation: market studies and the manufacturers' own guides recommend a tank "from ~30 pages a month upwards" (InkCartridges.com, 2024). But that threshold compares with original cartridges. As soon as you put compatible cartridges into the equation, the break-even shoots up to thousands of pages, because the price of your ink is no longer €0.10 but €0.03.

Independent sources put the tank's saving at between €300 and €600 over three years versus cartridge printers, with a typical payback in 12–18 months of regular use (Alibaba: ink tank vs cartridge cost analysis, 2024). The detail they leave out: that saving is measured against original ink. Against compatibles, the margin narrows enormously.

What exactly do Epson, Canon and HP promise?

The big three all promise enormous savings, and they're true… in the small print. Epson advertises "up to 90% savings on ink cost" on its European calculator (Epson Europe, 2025). Canon states that a set of MegaTank GI-21 bottles is equivalent to 30 standard cartridges in yield (Canon U.S.A., 2023). HP says its Smart Tank bottles yield up to 6,000 pages in black, "30 times more than a standard cartridge" (HP Tech Takes, 2024).

All those figures share the same hidden denominator: they compare tank ink against the brand's own ORIGINAL cartridges, the most expensive on the market. It's the comparison that flatters them most. Nobody shows you the "tank vs compatible cartridges" chart, which is the one that matters to you if you already have a printer.

Epson's methodology admits it without beating around the bush: the "up to 90%" comes from dividing the average selling price of bottles and cartridges by their yield, comparing with the original consumables of the 40 best-selling A4 inkjet models in Europe (Epson Europe: methodology, 2025). Change the point of comparison and the percentage collapses.

What is "cost per page" based on? The ISO standard

Cost per page isn't a number invented by marketing: it comes from an international standard. The ISO/IEC 24711 standard defines how the yield of a colour inkjet cartridge is measured, and ISO/IEC 24712 sets the test document (four typical pages plus a diagnostic one) that all manufacturers must print (ISO, 2021).

The important detail: the test is done in continuous printing, with at least nine cartridges, at 23 °C, on plain paper and with factory settings (Canon U.S.A., how yield is measured, 2024). Why does it matter to you? Because you don't print like that. If you print in bursts (a few pages today, nothing for two weeks) your inkjet will waste ink on head cleanings that the ISO standard doesn't count. That's exactly the scenario in which a tank yields worse than promised and a well-used compatible yields the same.

ISO yield is, in short, a laboratory number comparable across brands, not a promise of what you'll get at home. We develop it in how many pages a cartridge prints.

What if my machine is a laser, not inkjet?

If your printer is a laser, the equation changes fundamentally: laser uses toner, not ink, and its cost per page in black is usually even lower and more stable than a home inkjet's, with no risk of dried-out heads. There a tank printer almost never makes sense: you already have the cheap consumable.

The laser vs inkjet decision has its own article: laser or inkjet printer. And if you get tangled up in the terms, ink cartridge or toner: which is which clears it up in two minutes. For laser, your answer isn't a tank: it's a compatible toner for your model.

When a tank printer IS worth it

Let's be honest, because sometimes it's the right call:

• You genuinely print a lot: more than 250–300 pages a month (small business, freelancers, exam candidates, large families with lots of notes). At 150 pages/month, a Smart Tank pays for itself in about 2 months according to HP; at 50, in 6–7 (HP Tech Takes, 2024), again, comparing with originals.
• Your current printer is broken or very old and you're going to buy a new one anyway. If you're going to spend the money regardless, a tank has a better long-term cost than a cartridge machine + originals.
• You print a lot of colour photos and the volume is high and steady.

In those cases, go ahead: the high volume pays off the machine in one or two years.

When NOT to (and what to do instead)

For everyone else (the majority) a tank means buying a solution to a problem you can already fix for free:

• You print fewer than 200 pages a month.
• Your printer works perfectly.
• You print "in bursts" (some weeks a lot, others nothing), the worst scenario for any inkjet.

Here the smart move is crystal clear: keep your printer and stop buying original cartridges. The extra cost isn't in the machine, it's in the branded ink. Switching to compatible cartridges brings your cost per page down from ~€0.10 to ~€0.03 without spending a euro on a new printer.

👉 Check the compatible cartridge for your model: compatible cartridges and toner at star-toner.com. Same print result, up to 70% cheaper than the original.

"OK, but do compatibles print just as well?"

It's the number-one doubt, and it's a fair one. The short answer: a quality compatible cartridge uses the same per-page yield standard (ISO) and, in normal document and home-photo use, you won't notice the difference.

And we don't say this second-hand. At Star Toner we print and test our own compatible consumables before selling them: we print out text and photo pages, put them next to the original's and compare density, lines and bleed. On office documents and home photos we don't see a difference by eye; where you do have to be demanding is in professional colour photo printing, which is another league. We tell it with the tests in front of us in original vs compatible toner: we printed them side by side.

Three rules to not go wrong when buying compatibles:

1. Check your printer's exact model before ordering. If in doubt, we'll help you in how to know which toner your printer needs.
2. Beware of firmware: HP and other brands sometimes block non-original cartridges with updates. It can be avoided; you'll find it here: HP firmware that blocks cartridges.
3. Buy from a shop with a guarantee, not from opaque marketplaces. Your consumer rights cover you the same with compatibles: the legal guarantee on compatible cartridges in Spain.

In summary

Your situation	The smart decision
You print < 200 pp./month	Keep your printer + compatible cartridges
You print 200–300 pp./month	Grey area: compatibles still win unless you're heading higher
You print > 300 pp./month and steadily	A tank starts to pay off
Your printer is broken	Consider a tank as a replacement

The tank printer isn't a rip-off, but it isn't magic either. Before spending €230, do the maths above with your real volume. For 8 out of 10 people, the calculation ends in the same place: the printer you already have + compatible cartridges.

Frequently asked questions

How many pages does a tank printer take to pay off?
Versus compatible cartridges, break-even is around 9,600 pages (€230 ÷ ~€0.024 saving per page): about 250–300 a month over three years. Versus originals, some sources bring it down to 12–18 months (Alibaba, 2024), but that comparison doesn't apply if you use compatibles.

Is an EcoTank, a MegaTank or a Smart Tank better?
It depends on the model and whether you print more text or photos; we compare them in detail in our EcoTank vs MegaTank vs Smart Tank comparison. But the prior question (and the one that saves you the most money) is whether you need a tank at all.

How much do you really save with compatible cartridges?
As a guide, the cost per page drops from ~€0.10 (original) to ~€0.03 (compatible), a saving of around 60–70% on ink without changing printer. Tank manufacturers promise up to 90%, but always comparing against their own originals (Epson Europe, 2025).

Do compatible cartridges damage the printer?
A quality compatible doesn't damage the machine or void your legal guarantee. The real risk is firmware blocks, which are avoidable, and products of dubious origin: always buy with a guarantee. Extending their life also helps: how to extend the life of your cartridges.

How many pages a month does a normal person print?
A typical home is around 30–100 pages a month. At that volume, a tank printer takes many years to pay off versus compatibles: compatibles are almost always the cheapest option.
