Not every financial institution will conduct a formal RFP for calculator solutions — the investment level and operational complexity often don't require it. But for institutions that need to document vendor selection through a procurement process, or that want the discipline of a structured evaluation, a consistent framework ensures that the right criteria are evaluated consistently across all vendors under consideration.
Free calculator widgets are an appealing option for institutions that need to check a box — a mortgage calculator on the mortgage page — without a budget allocation for a managed program. They're quick to deploy, require no contract, and the price is hard to argue with. For credit unions specifically, NAFCU-affiliated services like CULookUp.com offer a library of roughly 30 free or low-cost calculators delivered via iframe — a widely used option in the community credit union space.
Financial calculator programs are typically evaluated by their subscription costs — the annual licensing fees charged by the vendor. This is a straightforward number that's easy to compare across vendors and easy to present in a budget discussion.
If you're evaluating Fintactix Financial Calculators versus Chimney, here's a breakdown of key differences to help you make an informed decision.
Founded in 2021 by SEO specialist Matthew Covi, Chimney has grown to about 20 employees and serves around 150+ banks and credit unions. Their primary offering is a white-label calculator platform, with approximately 40 available. Chimney has also introduced "Chimney Home," a homeowner tool currently in beta.
Choosing a financial calculator vendor is not a complex procurement decision, unlike a core banking system replacement or a new loan origination platform. But it's a decision that has a longer shelf life than most institutions expect, involves more stakeholders than it initially appears to, and carries risks — particularly around accessibility and ongoing maintenance — that aren't visible at the point of selection.
