Most online faxing services charge per page, similar to physical fax machines, or offer subscriptions that include a limited number of pages. Some online fax services instead use flat-rate subscriptions, which can be more predictable for people who fax regularly.
So what does this mean in practice? Let’s take a simple example using the average prices in the comparison table above. In many retail locations, faxing costs about $1.50 per page. If you only need to send one or two pages, the total cost may be similar whether you fax in person or use an online service.
But if you need to fax documents to a healthcare provider, submit paperwork for taxes, or send forms to a bank or credit card company, you might easily send around 25 to 30 pages once cover sheets and supporting documents are included. At typical in-store rates, that can add up quickly. Using a flat-rate online fax subscription changes the math. Instead of paying per page, the cost remains the same regardless of whether you send a few pages or several dozen.
For example, based on the averages above:
