Leuchtturm1917 A5 vs A4 Springback Binder: Which Office Notebook Actually Costs Less Over Time?

Every week, someone forwards me a question that looks like a math problem. "Where to buy a printer near me." "No tax on overtime calculator." "Decimal calculator." People want quick arithmetic. I get it—they need stuff, and the fastest answer is usually the one they remember.

But after five years of managing purchasing for a 45-person company—roughly $80,000 a year across 8 vendors—I've learned that quick arithmetic is rarely the whole answer. The question I actually answer is: what does this cost over time?

That's total cost of ownership (TCO, in plain terms: the price tag plus every cost that follows). And today, I want to apply that lens to two Leuchtturm1917 products people often ask me about:

• Leuchtturm1917 Notebook Hardcover Medium A5 (No. 251) — the classic 251-page notebook: numbered pages, table of contents, two bookmarks, thread-bound binding, gusseted pocket.
• Leuchtturm1917 Springback Binder A4 (Peka) — a refillable binder with a spring mechanism. Heavier build, designed for years of use with replaceable inserts.

I compared them across three dimensions: cost per year, what failure costs, and the value of your team's time. The third one surprised me. It might surprise you too.

Dimension 1: Unit Price Is a Lie

Someone with a decimal calculator will tell you the A5 is cheaper. They're looking at the shelf prices: about $26.95 for the A5 hardcover, roughly $72.00 for the Springback Binder (as of January 2025—verify current pricing, because it moves). That's a $45 gap at the register. Case closed, right?

Wrong. The A5 has 251 pages. Then it ends. You buy another. The binder keeps going, and refill pages run between $18 and $26 per pack (Leuchtturm1917, January 2025).

Let's do the math with an example. If someone in your office burns through one A5 per quarter—I have three of those people—you're at $107.80 per year. Over three years: $323.40.

The binder path: $72 upfront, plus about $88 per year in refills. Year one: $160. Years two and three: $88 each. Total over three years: $336.

Almost identical. Hmm. Let me re-check that. (Yes, I actually typed it into a spreadsheet.) They're within $13 of each other over three years.

The point? The "A5 is cheaper" claim is true only in the moment you swipe the card. The per-year number depends on how fast a person writes and how much you value the binder's advantages. So run the math for your actual team before you decide. Unit price is the beginning of the cost, not the end.

Dimension 2: What Failure Actually Costs

In 2020, I bought cheaper notebooks. Not Leuchtturm1917. Just... notebooks, $7 each. They looked fine on the spec sheet. I knew I should test one before ordering 60 units, but I thought: what are the odds? It's a notebook. How bad can it be?

The odds caught up with me. Three months in, spines cracked on two of them. Pages came loose. A lab manager walked up to my desk holding a small stack of paper-clipped sheets, asking "which notebook did these come from?" I didn't know. Neither did she.

That decision cost us about $400 in lost time and rework. I did that math once, and it hurt enough to stick.

The A5 hardcover from Leuchtturm1917 is thread-bound. In five years, I haven't seen a single one lose a page. The Springback Binder is in a different weight class—the mechanism is built like a proper lever arch, and ours in operations has been in daily use since 2022. Still closes cleanly. Still holds its paper.

The cheapest product isn't the one with the lowest price. It's the one that doesn't fail. Because failure has a cost—and usually, it's bigger than the savings.

Dimension 3: The Time Tax (the one everybody skips)

Now the one that flips the conclusion.

People ask me, half-joking, whether there's a no-tax-on-overtime calculator to figure out what their team's time is truly worth. I don't know that tool. But the instinct is right: time is a cost, and nobody writes it down.

The A5 is a self-contained unit. You take it to a meeting, write, close it, done. It's perfect for a project with a clear beginning and end—fill it, shelve it, and the archive is complete. Our field service team lives in these. For them, the binder would be dead weight.

The Springback Binder is a system. You can put printed documents into it next to handwritten notes. You can move sections, pull an insert out when it's full, file it, and carry on without losing your thread. That matters for people who manage long, messy, evolving projects—like our project coordinators. (Should mention: I didn't get this at first. I thought "it's just a fancy folder." Then one coordinator showed me how she had 14 months of project history in one binder, perfectly ordered. That was the moment it clicked.)

And here's the math nobody runs: if the binder saves a coordinator 15 minutes per week of searching for notes—and I'd argue it saves more—that's 13 hours per year. At $35/hour loaded cost, that's $455. The binder paid for itself before lunch.

The belief that "premium office supplies are a luxury" comes from an era when a notebook was just paper and glue. That era is old. The tool is part of the workflow now. And the workflow is part of the cost.

Which One Should You Actually Buy?

Go with the Leuchtturm1917 A5 Hardcover (No. 251) if:

• Your people move—field visits, client meetings, on-site work.
• Each notebook represents a single project or a defined period.
• You want a clean shelf archive: numbered, complete, finished.

Go with the Leuchtturm1917 Springback Binder A4 (Peka) if:

• Your people work at desks, managing work that shifts and grows.
• They need printed documents and handwritten pages in one place.
• You want to move from buying full notebooks to buying refills—and extend the product's life by years.

Buy neither if the true use case is scratch paper. I've seen companies spend $25 on a premium notebook for someone who needed a sticky-note pad. Don't overspend on a tool the job doesn't require. That's the other half of TCO.

The Bottom Line

People keep searching for quick answers. The nearest printer store. The perfect overtime calculator. The lowest list price. Those are arithmetic questions.

Procurement is an economics question.

I've processed maybe 60–80 orders a year since 2020—somewhere around 360 total, I'd have to check the system. I've consolidated vendors, learned the hard way that a supplier who can't produce a proper invoice costs you about $2,400 in rejected expenses (that one came straight out of my department budget), and stopped trusting the number on the tag.

So here's my real recommendation, after all that: for the Leuchtturm1917 A5 vs. the Springback Binder, stop asking "which one is cheaper?" Ask "which one is cheaper for your workflow, over the next three years?"

Run the numbers. Then buy. That's it.
