September 6, 2023

A $3B Credit Union's deposit campaign is an excellent example of how financial institutions can use calculators to solve customer problems and generate an impressive return on investment with strategic campaign execution.

This Credit Union ran a successful digital campaign featuring interactive savings and CD calculators across email, paid display, retargeting, SEO, SEM, and social media.

Campaign Highlights:

  • Campaign Goal: This 90-day campaign was aimed at engaging new and existing members to educate them about the benefits of saving at higher interest rates.
  • Increased Conversions: This campaign delivered a 34% conversion rate, which is 6x their typical 5% conversion rate.
  • Funded Accounts: They raised $6M in new deposits from 4K newly funded accounts.
  • Average Initial Deposit: They saw an initial deposit that was 146% higher than the average initial deposit in 2022.


New Year, New You! Like millions of Americans every year, many Credit Union members were struggling to save enough and did not know where to turn. In order to help members take advantage of their great rates, this Credit Union launched a CD and savings campaign that featured personalized, interactive guidance to help members achieve their savings goals.

As part of this initiative, the Credit Union launched a new landing page, which featured an optimized savings calculator and CD calculator to help members visualize potential savings and get connected to the right products. In addition to the landing page, Credit Union ran Google SEO and SEM campaigns, display, in-branch, social posts, and retargeting efforts with the calculator as the focus.

A Big Problem

While most Credit Unions focus on advertising rates and promoting generic offers, Credit Union decided to offer personalized financial guidance to help members understand how much they could save by.

Why interactive calculators?

The answer was simple, Credit Union members had voiced to the Credit Union marketing team that they want to get personalized answers from interactive tools.

Members were telling us they wanted to use calculators. They weren’t able find what we had and when they did they were confusing to them so it worked its way up to marketing as a big priority.

Before Chimney, Credit Union members weren't able to find the financial tools they were looking for and when they did, the tools were confusing to them. So Credit Union decided launching interactive calculators would be the best solution for their cross-channel campaign.

The requirements?

  • Easy to Use: The tool had to be on-brand, ADA-compliant, and a responsive design.
  • Not an iFrame: The tool had to be SEO optimized and measurable, so an iFrame would not work.
  • Personalized & Interactive: The tool had to be something that is modern and easy for members to use. Not an old tool that is frustrating for members.
  • Measurable Impact: The tool had to not only be easy to use but also generate measurable impact

The problem was finding a tool that was versatile, on-brand, easy to use, and would actually help members get into applications.

The Campaign Results

The campaign ran from January 25 to March 31, outperforming benchmarks and helping the Credit Union engage with their members, educate them about the process, and build trust.

The numbers

They generated over 4k funded accounts totaling $6M in new deposit.

2.5K people started applications from the calculator while 400 people booked appointments directly from the calculator - the top goal completions from the campaign came from Email, Online Banking, Google Organic, and Google Search.

Credit Union advertised in the following places: Google SEO/SEM, ATM ads, Digital Lobby Screens, Posters in the branch, Online Banking Ads, Ads, Display Ads, Retargeting Ads, Social Posts, and an email to members.

"The savings promo brought in 146% higher average deposit compared to the previous year, which is GREAT!"

Google Search: The campaign in full had a 34% conversion rate, which is 6x the typical 5-10% conversion rate for search.

The calculator was super easy to use and see what your payment would be, one of the reasons we chose chimney bc thye’re not only on brand but simple for people to understand. We could put the default based on our data (interest rates and our data).
