Case Study: a $3B credit union boosts deposits and conversions with Chimney calculators

a $3B Credit Union raises $6M in deposits with Chimney

A $3 billion credit union faced a challenge common to many financial institutions: its members struggled to save money and found the credit union's existing online financial tools difficult to use and hard to find. To address this, the credit union partnered with Chimney to implement interactive and personalized savings and CD calculators as the centerpiece of a new digital campaign.

Chimney provided on-brand, ADA-compliant calculators that were seamlessly integrated into a new landing page and promoted across multiple channels including email, SEO, SEM, and social media. This solution delivered exceptional results, generating a 34% conversion rate—6 times the credit union's typical rate—and driving $6 million in new deposits from 4,000 newly funded accounts. The campaign also resulted in an average initial deposit that was 146% higher than the previous year's average, demonstrating the measurable impact of the tools provided by Chimney.
