What a fax really costs in 2026: the full calculation

Short answer: a fax page sent from a business fax machine costs, in practice, between €0.80 and €2.50 — not the few cents most people imagine. The call charge is only a fraction of the total: the bulk goes on the dedicated line rental (€15 to €35 a month, whether you use it or not), consumables, maintenance and, above all, staff time — walking over to the machine, re-dialling a number, resending a transmission that failed. An online fax service shifts the balance: no line, no paper, and a cost that genuinely tracks volume. The calculation below gives you your own figure in ten minutes.

Nobody knows what a fax costs in their organisation. Ask an office manager: they will quote the per-minute call rate, sometimes the line rental. They will forget the toner, the maintenance contract signed in 2014, the reams of paper, the cover sheet printed twice, and the half-hour an assistant spends every week chasing failed transmissions to a foreign number.

That vagueness matters. It is precisely why a fax machine gets kept "because it costs nothing" when in fact it weighs more heavily than the solution that would replace it. Here is how to put real numbers on it.

The six cost items of a paper fax

1. The line rental

This is the dormant item. A dedicated analogue fax line historically cost between €15 and €25 excl. VAT per month. With the switch-off of the legacy copper network — Orange stopped selling new analogue lines in 2018 and has been closing exchanges area by area since 2023 — that line has been replaced by a VoIP connection, a SIP trunk channel or an ATA adapter. The price has not fallen: budget €12 to €35 excl. VAT per month depending on the carrier and the business contract.

That amount is paid regardless of volume. An organisation sending 20 faxes a month is therefore already paying €1 of line rental per fax before dialling a single number.

2. The calls

Here the rates really are low: a few cents a minute to a national landline, more for international destinations. A page in standard resolution takes 15 to 25 seconds; in fine mode, up to 45 seconds. Sending 4 pages to Germany at €0.10/min works out at around twenty cents.

The trap lies elsewhere: billed calls that never complete. A fax that connects, negotiates, fails on page 3 and hangs up is still billed to you. On poorly configured VoIP transmissions, the mid-transmission failure rate often exceeds 20% — the topic is covered in detail in our article on T.38 failures. Every failure doubles the call cost of the page concerned.

3. The hardware and its depreciation

A professional laser multifunction fax machine costs between €250 and €900 excl. VAT. Depreciated over five years for a department sending 30 faxes a month, that adds €0.30 to €1 per fax. An entry-level model looks cheap to buy, but its per-page consumables cost is almost always higher — the classic loss-leader hardware model.

On top of that come the accessories nobody budgets for: a UPS for router and fax machine, essential now that the line depends on mains power (the old copper line was powered from the exchange), and sometimes an ATA fax adapter if the carrier does not supply one.

4. Consumables

The real cost centre of paper:

On paper — literally — you are at €0.05 a page. Except that the page printed is not the page sent. There is the cover sheet, the draft that gets proofread, the archive copy, the incoming fax printed then thrown away, the junk faxes received and printed too. The real ratio is frequently 2 to 3 printed pages per useful page. Reckon on €0.10 to €0.15 per useful page, and keep a pack of compatible toners in reserve if your department cannot tolerate a day of downtime.

5. Maintenance and incidents

Maintenance contract, a telecom engineer's call-out when the line "stopped working after the migration", fixing the recurring paper jam: anywhere between €0 (small outfits that muddle through) and €200 excl. VAT a year. Divided by 360 faxes a year, that is still €0.55 per fax at the top end.

6. Staff time — the heaviest item by far

This is the one people refuse to count, and it is the most expensive. Let's break down a real paper transmission:

• print the document and the cover sheet: 1 min
• walk to the fax machine, wait for it to be free: 2 min
• dial the number, load the feeder, keep an eye on it: 2 min
• collect the transmission report, file it: 2 min
• if it fails (1 time in 5), start again: +4 min as a weighted average

Total: roughly 11 minutes per transmission. At the fully loaded cost of an administrative role — €32,000 a year including employer contributions, or about €0.30 a minute — that comes to €3.30 of time per fax. Five to ten times the technical cost.

Sending from an online service, with an address book and a saved cover-sheet template, drops to 2 or 3 minutes, or under €1.

Three worked scenarios

Let's take three common profiles and calculate the full monthly cost, time included.

The small professional practice: 15 faxes a month

Low volume penalises paper heavily: the line rental and depreciation are fixed.

The multi-site SME: 4 branches, 200 faxes a month

Four dedicated lines, four fax machines, four stocks of consumables. Fixed costs multiply by the number of sites while volume per site stays modest.

• Paper: 4 × (18 + 6 + 8) = €128 of fixed costs, + €20 of calls, + 200 × 11 min ≈ €660 of time → ≈ €808/month, or €4.04 per fax.
• Online, with a single number and routing by department: subscription €40–70, pages included or billed, time 200 × 3 min ≈ €180 → ≈ €240/month, or €1.20 per fax.

This is where the gap becomes structural. Consolidating numbers is covered in our multi-site fax guide.

The high-volume department: 1,200 faxes a month

At this level, the per-page cost regains importance and "unlimited" online plans deserve a close read of their fair-use policy. Paper remains more expensive, but the gap narrows on the technical items — the advantage then comes mainly from time savings and automatic audit trails. A desktop scanner with duplex feeder becomes, in that case, an investment that pays for itself in a few weeks, because it removes the slowest step: scanning page by page.

The costs everyone systematically forgets

The number kept "just in case". Many organisations pay for a line for months after switching online, out of fear of losing the number. Porting exists: see our article on keeping your fax number. One month of double subscription is normal; six months is money thrown away.

Junk faxes. Advertising, fax spam: every page received uses up toner and paper, plus the time of whoever bins it. In a department receiving 100 faxes a month, 10 to 20% fall into this category.

The cost of a silent failure. A fax that never arrives and whose report nobody checks can cost you a case file, a procedural deadline, a refused claim. That cost appears on no invoice, but it is by far the highest.

Electricity. A laser multifunction device on standby draws 5 to 15 W continuously, plus printing peaks. Over a year, a few tens of euros — marginal, but real. A switched power strip is enough to cut peripherals outside office hours.

Space and physical archiving. A linear metre of paper archives takes up floor space that carries rent. Moving to digital archives does, in return, require serious backup: an external hard drive for backups costs less than a fireproof cabinet.

How to work out your own figure in ten minutes

1. Count your actual volume over three months: the fax machine's transmission log or the carrier's itemised statement. Not an estimate from memory — the gap between perception and reality often reaches 50%.
2. Pull out the telecom invoice and isolate the fax line: rental, usage, add-ons.
3. Estimate consumables over twelve months: toner and paper orders attributable to the fax station.
4. Time a transmission — really, stopwatch in hand, including the walk. Multiply by your volume and by the per-minute cost of an administrative role (annual loaded salary ÷ 1,600 h ÷ 60).
5. Add the failure rate: in your log, count the "failed" or "busy" lines and express them as a share of the total.
6. Divide the annual total by the number of useful faxes.

The resulting figure is almost always a surprise. Write it down: it is your benchmark against any offer, and the only argument that works in a budget meeting.

What actually brings the bill down

• Stop printing every incoming fax. Fax-to-email cuts the consumables item by three — see the guide to receiving faxes by email.
• A shared, verified address book. Half of all failures come from a wrong or badly formatted number. Check the international format before sending using our supported countries page.
• A saved cover-sheet template, never reprinted.
• Consolidating numbers across sites: a single inbound number routed by department costs a fraction of four lines.
• Sending in standard resolution when the document allows: fine mode doubles the call duration for a gain that is often nil on printed text.
• Closing lines that have become redundant, with a written deadline in the migration plan.

Frequently asked questions

Is an online fax always cheaper than a fax machine?

Almost always, as soon as you count staff time and the line rental. The theoretical exception: an organisation that receives a lot and never sends, with a fax machine already written off and a line shared with voice. Even then, the cost of paper and archive space closes the gap within two or three years.

Why do "per page" rates vary so much between countries?

Because call termination — what the local carrier charges to carry the call — differs enormously from one country to another, and because some destinations require several attempts. The topic is developed in our article on international sending.

Should faxes be charged back internally to departments?

In large organisations, yes: even a token internal charge cuts volume by 20 to 40% within a few months, simply because users finally stop to ask whether the transmission is necessary.

Does the cost really fall with volume?

On the technical items, yes. On staff time, no: ten times more faxes means ten times more minutes, unless you automate sending from your business applications. That is where the real high-volume gain lies.

How do I justify the budget for an online service when "the current fax costs nothing"?

By presenting the six-item table, with your figures and your transmission log. The objection collapses as soon as the line rental and the staff time appear on the same page as the price of toner.

Key takeaways

• The real cost of a paper fax page sits between €0.80 and €2.50, and the cost per complete transmission between €3 and €5 in small organisations.
• Calls are the smallest item; line rental and staff time are the heaviest.
• Fixed costs penalise low volumes and multi-site organisations: that is where going online pays off most.
• Three levers are enough to halve the bill and more: stop printing incoming faxes, make numbers reliable, close redundant lines.
• Measure before you decide: three months of transmission logs and an honest stopwatch beat any sales estimate.
