MLS and IDX Cost Calculator
This calculator adds up published fees for an MLS or IDX setup: 8 IDX plugin plans, license fees from 5 MLSs, and 10 RESO Web API vendor plans. It shows the total per month and per year, and links every figure to the page it comes from.
It is an adding machine, not a quote. It contains no Peregrine prices, it covers only the MLSs and vendors cited in our MLS and IDX cost guide, and fees change, so confirm each one with the provider. Fees last checked .

What the Total Does and Does Not Include
Included: the published subscription, license, establishment and connection fees for the options you pick, and, if you enter hours, a development range at the market hourly rates Clutch reports.
Not included: setup fees a vendor does not publish, tiered or usage-based fees, maps, hosting and other infrastructure, MLS membership or broker dues, and fees from any MLS that is not listed. There is no national MLS price list: each board sets its own fees, and the same data is priced differently for brokers and for vendors.
Development hours are yours to enter. We do not suggest a number, because the work depends on how many boards you combine, how fresh the data must be and what you build on top. Our guide on what it costs to build a real estate platform explains what drives it.
Before you can pay any of these fees you need data access. See how to get MLS data access for your app, or our MLS and IDX integration service if you want the pipeline built.
