Compare fax services
How much does an online fax service actually cost?
Enter how many pages you need to fax now. The calculator compares what that one fax costs with PayPerFax against the least a leading subscription can cost: its shortest term, usually one month, plus any required setup fee. A first-month promo price counts if you need no code to get it. You see which one costs less for this fax. 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 comes from the vendor’s public pricing page. The date we last checked each card by hand is at the bottom of the card.
eFax
eFax Personal
$18.99/month for 200 included pages to the US and Canada, 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. You can cancel online; annual plans and accounts with more than one number cancel by chat, email or phone.

RingCentral
RingCentral Fax 3000
$27.99/month month to month, or $22.99/month billed annually, for 3,000 included pages, then $0.049 per additional page.
Priced for a small business or law firm that sends hundreds of pages a month. RingCentral retired its 1,500-page plan, so this is now its only standalone fax plan. Makes sense if you are well past the 500-page mark every month. Below that, most of your allowance goes unused and a smaller plan or pay-as-you-go beats it on cost per page.

MetroFax
MetroFax Essential
$11.95/month for 550 included pages, then $0.03 per additional page.
The cleanest consumer pricing in the field: low monthly fee, generous 550-page pool, cheap overage. Makes sense if you consistently send 40 or more pages a month and want inbound faxing on a dedicated number. No contract and 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 local 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 part of Dropbox: hellofax.com redirects to fax.dropbox.com, and the HelloFax login now opens Dropbox Fax. 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). 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 a 14-day free trial on the annual plan. 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
$17.99/month month to month, or $13.99/month billed annually, 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 $99.99/month ($79.99/month billed annually), 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
Six questions before you pick
Is PayPerFax always cheaper?
No. For a few faxes, paying per fax can cost less than a subscription. If you fax a lot every month, a subscription spreads its fee across many pages and can cost less per page. It depends on the plan and on how many pages you send. The calculator above compares one fax: for the pages you need to send now, it shows whether PayPerFax or the least a subscription can cost is cheaper.
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 compare the price of that fax with the least a subscription can cost, and read its cancellation terms. If you keep a subscription for the whole year, you pay twelve months 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, setup fees, and number-porting charges when you leave. For each service, the calculator counts the least it costs to send this fax: one month of the plan (or the minimum term, if the plan has one), plus any mandatory setup fee and any pages over the allowance. If the vendor gives new buyers a lower first-month price with no code, the calculator uses that price for the first month and shows the full fee in the renewal line. It does not add up a monthly or yearly total. If you fax every month, count the fee for every month you keep the plan. Other one-time charges, such as number porting, are on the vendor’s pricing page.
How often do these prices change?
Not often, but often enough that a comparison page needs a maintenance plan. On the 1st of each month, we check the calculator prices against each vendor’s public pricing page. If a price changed or the page cannot be read, we flag it for a manual check. Each card above shows the date we last checked it by hand. If you spot a difference from a vendor’s live pricing page, tell us and we will fix it the same day.
Does any of this work with an AI assistant?
PayPerFax does. If your AI assistant is connected to PayPerFax, it can prepare the fax and give you a link to review and pay. You do not need a monthly plan or an account. You pay once for each fax, in your browser.
