How much does an online fax service actually cost?
Enter your monthly page count. The calculator does the math for ten leading subscription vendors and PayPerFax, and tells you which one is genuinely cheapest for your volume. If it is not PayPerFax, the calculator says so.
Two pricing approaches
Subscription vs pay-as-you-go, in plain terms
A subscription fax service charges a flat monthly fee for a fixed page allowance, plus per-page overage above the allowance. You get a dedicated fax number, a login, and the same bill whether you send one page or hit the cap. Overage rates vary by tier. Subscription makes sense when you send more than a few dozen pages a month, need people to fax you back, or work in a regulated field that requires an ongoing account.
Pay-as-you-go charges only for what you send, with no monthly fee and no account to cancel later. PayPerFax charges $2 for the first three pages and $0.75 for each additional page, and nothing at all if the fax fails to deliver. Pay-as-you-go makes sense when your fax needs are occasional (a signed lease, a medical form, a bank document) and a subscription would sit unused between sends. For the wider set of pay-as-you-go options, see our pay-as-you-go fax comparison.

The ten subscription options
What each service charges, and when it makes sense
Every price below is pulled from the vendor’s public pricing page and re-verified monthly. The last-verified date appears at the bottom of each card.
eFax
eFax Plus
$18.99/month for 170 included send pages, then $0.10 per additional page.
The default entry tier at the best-known brand in online fax. Makes sense once you send more than about 30 pages a month consistently and want a dedicated inbound number. eFax also charges a one-time $10 activation fee that is not disclosed on the landing page, and cancellation is by phone only.

RingCentral
RingCentral Fax 1500
$17.99/month for 1,500 included pages, then $0.049 per additional page.
Priced for a small business or law firm that sends several hundred pages a month, but only advertised at $17.99/month with annual billing. Makes sense if you are past the 500-page mark and comfortable committing to a full year up front. Below that, most of your allowance goes unused and a smaller tier or pay-as-you-go beats it on cost per page.

MetroFax
MetroFax Essential
$11.95/month for 500 included pages, then $0.03 per additional page.
The cleanest consumer pricing in the field: low monthly fee, generous 500-page pool, cheap overage. Makes sense if you consistently send 40 or more pages a month and want inbound faxing on a dedicated number. Cancel online with no early-termination fee. Below 40 pages a month, it is still a subscription for volume you are not using.

SRFax
SRFax Healthcare Lite
$12.60/month for 200 included pages, then $0.05 per additional page.
The HIPAA-first plan an SRFax buyer actually lands on now that the general pricing grid has been de-emphasized. Makes sense if you send at least 25 pages a month inside a regulated healthcare workflow and want the audit-friendly account model. Extra fax numbers are $4.95 each and porting a number in is $25.

Dropbox Fax
Dropbox Fax Home Office (formerly HelloFax)
$9.99/month for 300 included pages, then $0.05 per additional page.
The former HelloFax product, now consolidated under Dropbox: hellofax.com redirects to fax.dropbox.com and existing accounts have been migrated. Makes sense if you send 25 or more pages a month and Dropbox is already the center of your workflow. Otherwise the integration is not worth the monthly fee.

Documo
Documo Solo Cloud Fax (formerly mFax)
$25.00/month, billed annually only at $300 up front, for 300 included pages, then $0.15 per additional page.
Positioned upmarket as a HIPAA-included cloud fax platform, absorbing what used to be mFax (mfax.io now redirects to documo.com). Makes sense if you send 50 or more pages a month, need a Business Associate Agreement at the entry tier, and are OK committing to a full year up front. Documo publishes $25/month but there is no separately priced month-to-month tier.

Nextiva
Nextiva vFAX Essential
$9.95/month for 500 included pages, then $0.03 per additional page.
The cheapest headline monthly fee in the mid-volume set, with a generous 500-page pool and low overage. Makes sense if you consistently send 40 or more pages a month and do not need a Business Associate Agreement (the HIPAA plan is sales-gated). Toll-free numbers carry a one-time $9.95 setup charge, and failed faxes do not count against the pool.

MyFax
MyFax Home Office
$12.00/month for 100 included send pages, then $0.10 per additional page.
The Consensus-owned sibling to eFax, priced for lighter home-office use with the longest free trial in the consumer set. Makes sense if you send around 25 to 100 pages a month and want to try before you commit. Read the cancellation terms closely: recurring “billed after cancel” complaints on Trustpilot are the pattern to watch.

Fax.Plus
Fax.Plus Premium
$13.99/month for 500 included pages, then $0.07 per additional page.
A Swiss vendor (Alohi) that bills US customers in USD, with a free lifetime tier of 10 pages for one-off tests. Makes sense if you send 30 or more pages a month and can live inside the 90-page-per-fax cap. HIPAA and a BAA are Enterprise-only at $79.99/month, so it is not the pick for regulated workflows.

Concord
Concord FaxPro 100
$10.95/month, month-to-month billing, for 50 included send pages, then $0.07 per additional page.
The other Consensus-owned option, sibling to eFax but priced and billed on its own. Makes sense if you send around 25 to 50 pages a month and want month-to-month billing with no annual commit. A Business Associate Agreement is available on request at every tier, and long faxes (over 72 seconds of transmission) carry a surcharge.

Frequently asked
Five questions before you pick
Is PayPerFax always cheaper?
No. One-time-fax pricing beats every subscription until you cross a per-service break-even volume. Above that volume, a subscription’s flat rate spreads across enough pages that it wins on cost per page. The calculator above shows the exact crossover for your numbers. Below about 20 pages a month, PayPerFax is cheapest across all ten subscription services on this page. Between 20 and 100 pages a month, the winner depends on which tier you fit into. Above 100 pages a month, a subscription almost always wins on cost alone.
What counts as a page?
Every service on this page counts one standard letter-sized page as one page, whether the source document is a PDF, a Word file, or a scanned image. Cover pages count. Two-sided originals are two pages. PayPerFax includes an optional cover page in the first three pages, so a two-page document with a cover ships for the base $2 rate. See our full pricing page for the exact page-count rules on the PayPerFax side.
What if I only need to fax once (or once a year)?
Then no subscription on the market is going to be cheaper than paying for a single fax. At one fax a year, the cheapest subscription in the grid above still costs you twelve months of billing for the one fax you actually send. PayPerFax costs $2 for that fax and nothing for the other eleven months. If you have a signed document that needs to go through today and you never want to think about a fax service again, use PayPerFax as a one-time send. There is no account to close afterward.
Do subscription services have hidden fees?
“Hidden” is the wrong word; the fees are disclosed, just often outside the headline price. The most common ones are per-page overage above the included allowance, per-page international sending rates, and setup or number-porting charges on cancellation. The calculator uses the vendor’s public overage rate on every service, so the annual number you see is realistic for your volume. Setup and porting charges are one-time and are not modeled here.
How often do these prices change?
Not often, but often enough that a comparison page needs a maintenance plan. We re-verify every vendor’s public pricing page on the 1st of each month. The last-verified date appears on each card in the grid above; if any date is more than 45 days old, that card is flagged for a manual re-check. If you spot a discrepancy against a vendor’s live pricing page, tell us and we will update the same day.
