The Directory Submission Cost Calculator is a free online tool developed by SubmitSaaS that helps SaaS businesses estimate the total cost of submitting their product to online directories. Its primary function is to compare three cost paths: the time cost of doing it yourself, the paid listing fees required by certain directories, and the cost of using a done for you submission service. The tool calculates a break even point to help users determine the most cost effective approach before beginning a directory submission campaign. The calculator accounts for several cost components, including the hourly value of the user's time for tasks such as form filling, account creation, uploads, and navigating submit page friction. It also factors in the time spent checking directory fit, pricing, link type, and submit URL before each submission, as well as one time work for creating descriptions, taglines, screenshots, logos, and categories. Users can input the number of directories they plan to target and the tool outputs a breakdown of DIY time cost, paid listing fees, and service package pricing. The tool is free to use and requires no account creation or technical setup. Typical use cases include planning a directory submission campaign, budgeting for paid listings, and evaluating whether to outsource the work to a service provider. The workflow involves selecting a campaign size, reviewing the estimated costs, and comparing the DIY total against service packages. The tool also provides information on service packages that include submission to 60 or 140 directories, guaranteed Domain Rating increases, and complete submission reports, with paid directories excluded from the service scope. The calculator is designed for SaaS founders, marketers, and growth teams who want to allocate resources efficiently when building backlinks and generating organic traffic through directory listings.
